Writing the Equation of
a
What is the equation of a line that is parallel to the line 2x + 5y = 10 and passes through the point (-5, 1)? Check all
that apply.
y=-2x-1
2x + 5y = -5
y=-2x-3
2x + 5y = -15
1= -2.(x + 5)
Answer: 2x + 5y = -5
Step-by-step explanation:
Two lines are said to be parallel if they have the same slope.
The equation of the line given :
2x + 5y = 10
To find the slope , we will write it in the form y = mx + c , where m is the slope and c is the y - intercept.
2x + 5y = 10
5y = -2x + 10
y = -2/5x + 10/5
y = -2/5x + 2
This means that the slope is -2/5 ,the line that is parallel to this line will also have a slope of -2/5.
using the formula:
[tex]y-y_{1}[/tex] = m ([tex]x-x_{1}[/tex] ) to find the equation of the line , we have
y - 1 = -2/5(x -{-5})
y - 1 = -2/5 ( x + 5 )
5y - 5 = -2 ( x + 5 )
5y - 5 = -2x - 10
5y + 2x = -10 + 5
therefore :
2x + 5y = -5 is the equation of the line that is parallel to 2x + 5y = 10
Answer: 2x + 5y = -5

y=5x translate down 3 units
Answer:
y = 5x - 3.
Step-by-step explanation:
The value of y will go down by 3 units so it is
y = 5x - 3.
The equation y = 9 + 3x represents a line with a y-intercept of 9 and a slope of 3. To translate the line down 3 units, subtract 3 from every y-coordinate.
Explanation:The equation y = 9 + 3x represents a line with a y-intercept of 9 and a slope of 3. The y-intercept is the point where the line intersects the y-axis, and in this case, it is the point (0, 9). The slope of 3 means that for every increase of 1 on the horizontal axis, the line rises up 3 units on the vertical axis.
To translate the line down 3 units, we can subtract 3 from every y-coordinate. This means that the equation becomes y = 9 + 3x - 3, which simplifies to y = 6 + 3x.

O A. $46,000
OB. $46,200
OC. $46,500
OD. $47,400
O E.
$48,600
Option D
The total earnings of Yvette is $ 47, 400
Solution:
Given that, Yvette earns a $45,000 salary plus a 12% commission on any sales over $10,000
Last year Yvette made $30,000 in sales
Subtract 10,000 from her sales to get the amount she earns commission on:
30,000 - 10,000 = 20,000
Since Yvette gets 12% commission
So amount earned as commission would be 12% of $20,000
[tex]\text{Commission}=20000\times \frac{12}{100}\\\\\text{Commission}=20000\times 0.12\\\\\text{Commission}=2400\left\\\\[/tex]
Yvette also gets a salary of $45,000, so Yvette's total earnings would be $45,000 plus $2,400
[tex]Total\ Earnings = 45000 + 2400 = 47400[/tex]
Thus total earnings of Yvette is $ 47, 400

[tex]6x+a=5t(x+t)[/tex]
We have to make [tex]x[/tex] the subject of formula. That means we have to isolate [tex]x[/tex].
[tex]6x+a=5t(x+t)[/tex]
Distribute [tex]5t[/tex]
[tex]6x+a=5tx+5t^2[/tex]
Subtract [tex]a[/tex] both side we get,
[tex]6x+a-a=5xt+5t^2-a[/tex]
[tex]6x=5xt+5t^2-a[/tex]
Subtract [tex]5xt[/tex] both side we get,

Mr. Lane’s math classes had the pass rates shown. In class 1, 16 out of 24 passed. In class 2, of the class passed. In class 3, 75% of the class passed. In class 4, 0.81 of the class passed. Which class had a pass rate that was exactly 5% greater than another class’s pass rate?
A.Class 1 B. Class 2 C. Class 3
Answer:
Answer 4/5 or class 2
Step-by-step explanation:
4/5=0.80 Class 3 is 70% 75+5=80, or 80%
Final answer:
After converting the pass rates of the classes to percentages, none of the classes have a pass rate that is exactly 5% greater than another class's pass rate.
Explanation:
The student's question pertains to comparing the pass rates of different math classes to determine which class had a pass rate that was exactly 5% greater than another class's pass rate. To answer this, we need to convert the pass rates for each class to a percentage and then compare them.
For class 1, the pass rate is 16 out of 24, which can be converted to a percentage by dividing 16 by 24 and then multiplying by 100, resulting in approximately 66.67%. Class 3 has a pass rate of 75%, as provided. Class 4 has a pass rate of 0.81, which is already in a decimal format comparable to a percentage; it is simply 81% when expressed as a percentage.
By comparing these percentages, we find that Class 3's pass rate is exactly 5% greater than Class 1's pass rate (75% - 66.67% = 8.33%, which is more than 5%). Therefore, none of the classes have a pass rate that is exactly 5% greater than another class's pass rate.

The graph of a linear function F is given
Answer:
Step-by-step explanation:
This line goes through the y-axis at 6; therefore, the coordinate at this point is (0, 6).
This line goes through the x-axis at 2; therefore, the coordinate at this point is (2, 0).
The rate of change of a linear function (aka a line) is the slope of the line. We can use the slope formula to solve for the slope:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Filling in with our coordinates:
[tex]m=\frac{0-6}{2-0}=-\frac{6}{2}=-3[/tex]
The rate of change is -3. This means that y decreases 3 with every increase in x of 1.

Tower A is 90 feet tall. Tower B is 180 feet tall. Tower C is 5 times as tall as both Towers A and B combined. How tall is Tower C?
Answer:
1350
Step-by-step explanation:
I added tower A and B together (90+180) Which gives me 270. Then I did;
270 * 5= 1350 ft. Hope its correct!
Final answer:
Tower C is 5 times as tall as the combined height of Tower A (90 feet) and Tower B (180 feet), which together are 270 feet tall. Multiplying this by 5 gives us the height of Tower C, which is 1350 feet.
Explanation:
The question asks us to calculate the height of Tower C given the heights of Tower A and Tower B and the relationship between their heights. Tower A is 90 feet tall, and Tower B is 180 feet tall. According to the question, Tower C is 5 times as tall as both Towers A and B combined.
To find the combined height of Towers A and B, we simply add their heights:
Tower A height: 90 feetTower B height: 180 feetCombined height of Tower A and B: 90 + 180 = 270 feetNow, we need to calculate the height of Tower C:
Height of Tower C = 5 × (Height of Tower A + Height of Tower B)Height of Tower C = 5 × 270 feetHeight of Tower C = 1350 feetTherefore, Tower C is 1350 feet tall.

can someone help me figure out this
Answer:
Therefore the first option gives the correct answer of a system of equations which has exactly one solution.
Step-by-step explanation:
i) the second option is 2x + 2y = 1 and -2x -2y = 1 . these two equation can be written as 2x + 2y = 1 and 2x + 2y = -1. Therefore we can see that that the expressions for used for the variables x and y are the same but the result is different. This is not possible and so there will be no solutions for these two equations
ii) the third option is 3x + y = -1 and 6x + 2y = -2. therefore these two equations can be written as 3x + y = -1 and 3x + y = -1 (dividing the second equation by 2) and thus we see that both the equations are exactly the same and hence these two equations will have an infinite number of solutions.
iii) the last option is 3x - 2y = 4 and -3x + 2y = 4. these two equations can be written as 3x - 2y = 4 and 3x - 2y = -4. Again we can see in this case that the two equations are exactly the same and therefore these two equations will have an infinite number of solutions.
iv) the remaining option is the first one 2x + y = 3 and 5x - y = 11. If we add the first equation to the second one we 7x = 14 and therefore x = 2. If we substitute x = 2 in the first equation we get (2 × 2) + y = 3, therefore y = -1.
Therefore the first option gives the correct answer of a system of equations which has exactly one solution.

Which of the following has congruent base angles?
A
all trapezoids
B
all isosceles trapezoids
C
all kites
D
all quadrilaterals
All isosceles trapezoids have congruent base angles.
Option A
Explanation:
An isosceles trapezoid is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides.
Properties of isosceles trapezoid:
Opposite sides of an isosceles trapezoid are the same length (congruent). The angles on either side of the bases are the same size/measure (congruent).The bases (both top and bottom) of an isosceles trapezoid are parallel.Note: Refer the attached file for the image of an isosceles trapezoid.
All isosceles trapezoids come into the category of trapezoids but all trapezoids cannot be marked as isosceles. Clearly, if a trapezoid has congruent legs, it is an isosceles trapezoid.
If a trapezoid has one pair of congruent base angles, then the trapezoid is isosceles. A trapezoid is isosceles if and only if its diagonals are congruent.
In the case of quadrilaterals, if the quadrilateral is an isosceles trapezoid, then each pair of base angles are congruent.
The shape that has congruent base angles is all isosceles trapezoids, as they have two pairs of congruent sides which result in two pairs of congruent base angles due to their geometric properties.
After excluding options such as all trapezoids, all kites, and all quadrilaterals which do not necessarily have congruent base angles, it becomes evident that the correct answer is all isosceles trapezoids.
An isosceles trapezoid is defined as a trapezoid where the non-parallel sides (legs) are congruent. According to geometric properties, these congruent non-parallel sides imply that the base angles are also congruent. So, an isosceles trapezoid always has two pairs of congruent base angles.
To support this, consider the Theorem, in an isosceles triangle the angles opposite the equal sides are equal. Similarly, by applying this to the two triangles that form when dividing an isosceles trapezoid along the line of symmetry, it becomes clear why the base angles are congruent.
Find the measure of x in each figure
Answer:x=40
Step-by-step explanation:
The measure of x in each figure, you need to solve the equation 4x + 20 = 180° by isolating the term with x and then solving for x. The solution is x = 40°, so the measure of x is 40 degrees.
The value of x. The given equation is 4x + 20 = 180°, representing a linear pair of angles.
Subtract 20 from both sides of the equation to isolate the term with x:
4x + 20 - 20 = 180 - 20
4x = 160°
Divide both sides of the equation by 4 to solve for x:
(4x)/4 = 160/4
x = 40°
Therefore, the solution to the equation is x = 40°.

Look at the following sequence.
128, 320, 800, 2000, . . .
If it is a geometric sequence, choose the common ratio. If it is not a geometric sequence, choose “not geometric.
Answer:
geometric sequence
Step-by-step explanation:
If the sequence is geometric then there must be a common ratio r between consecutive terms, that is
320 ÷ 128 = 2.5
800 ÷ 320 = 2.5
2000 ÷ 800 = 2.5
Since there is a common ratio r = 2.5 between consecutive terms.
Then the sequence is geometric
A restaurant sells drinks in 3 sizes of cups: small, medium, and large. The small cup costs $.89 and holds 9 ounces. The medium cup costs $1.29 and holds 12 ounces. The large cup costs $1.59 and holds 15 ounces. Which size cup costs the least per ounce?
Answer: the small cup cost the least per ounce
After calculating the cost per ounce for each cup size, we find that the small cup costs the least per ounce at $0.0989, making it the best value.
To determine which size cup offers the best value per ounce, we need to calculate the cost per ounce for each size. This can be done by dividing the cost of each cup by the number of ounces it holds.
For the small cup: $.89 / 9 ounces = $0.0989 per ounce
For the medium cup: $1.29 / 12 ounces = $0.1075 per ounce
For the large cup: $1.59 / 15 ounces = $0.106 per ounce
Now, comparing the cost per ounce for each cup size, we can see that the small cup offers the best value at $0.0989 per ounce.
