Answer:
q = 10
Step-by-step explanation:
The desired form is a rearrangement of the given equation, divided by the leading coefficient.
Monic polynomialA monic polynomial is one with a leading coefficient of 1. The desired form requires that we start from that condition. In order to avoid fractions, we can begin by subtracting the constant term on the left.
2x^2 -20x +49 = 19 . . . . . . given
2x^2 -20x = -30 . . . . . . . . subtract 49
x^2 -10x = -15 . . . . . . . . . divide by 2
Completing the squareThe square of the binomial a+b is given by ...
(x +b)^2 = x^2 +2bx +b^2
That is the constant term on the right is the square of half the coefficient of x. To achieve this perfect square trinomial in our equation, we need to add the square of half of -10.
x^2 -10x +25 = -15 +25 . . . . . . add (-10/2)^2 = 25 to both sides
(x -5)^2 = 10 . . . . . . . . . . . write in the desired form
The value of q in the form ...
(x -p)^2 = q
is 10.

Line m is parallel to line p. M angle HEF IS 39 degrees. And m IGF is 13 degrees. Find the m EFG. Explain in detail how you know you are correct. I WILL MARK THE BRAINLIEST
Answer:
[tex]m\angle EFG=52^{o}[/tex]
Step-by-step explanation:
We have been given that line m is parallel to line p, [tex]m\angle HEF=39^{o}[/tex] and [tex]m\angle IGF=13^{o}[/tex].
Since line m is parallel to line p and EJ is a transversal, so measure of angle EJG will be 39 degrees as angle EJG is alternate interior angle of angle HEF. Both angles are inside parallel lines m and p and on opposite side of transversal EJ.
We can see that angle EFG is exterior angle of triangle GFJ. Since the measure of an exterior angle of a triangle equals to the sum of the opposite interior angles.
We can see that angle IGF and angle EJG are opposite interior angles of angle EFG.
[tex]m\angle EFG=m\angle IGF+m\angle EJG[/tex]
Upon substituting our given values we will get,
[tex]m\angle EFG=13^{o}+39^{o}[/tex]
[tex]m\angle EFG=52^{o}[/tex]
Therefore, measure of angle EFG is 52 degrees.

6a. Suppose you need to find a box that you can fit your cube-shaped gift into. You know that you will need to find a box that is 4 inches longer than the cube’s length, 3 inches wider than the cube’s width, and 7 inches taller than the cube’s height. Create a polynomial that represents the gift box’s volume in terms of the cube’s length/width/height, in factored and standard form
Answer:
( l + 4) * ( w + 3 ) * ( h + 7)
let l represent the length, w represent the width, and h represent the height of your cub-shaped gift.
Though, if your gift is in the shape of a cube, that would mean all the sides are the same length.
( 2 + 4 ) * ( 2 + 3 ) * ( 2 + 7 )
6 * 5 * 9 = 270
(I haven't done geometry in awhile though, so this may be incorrect unless it actually makes sense.)
Answer:
V = (x+ 4)(x + 3)(x + 7); V = x³ + 14x² + 61x + 84
Step-by-step explanation:
Let x = the side of the cube
Then the dimensions of the gift box are
l = x + 4
w = x + 3
h = x+ 7
V = lwh
V = (x+ 4)(x + 3)(x + 7) Multiply the first two terms
V = (x² + 7x + 12)(x+ 7) Remove parentheses
V = x³ + 14x² + 61x + 84

Wells college Aurora New York Was previously an all girls college.In 2005 the college began to allow boys to enroll.By 2012 The ratio of boys to girls was 3 to 7. If there were 200 more girls than boys in 2012 how many boys in enrolled that year
Answer:
150
Step-by-step explanation:
The ratio of boys to girls is 3 to 7.
We don't know the number of boys or girls. The number of boys and the number of girls are multiples of 3 and 7, respectively. Since they are in the ratio of 3 to 7, then by multiplying both 3 and 7 by the same number, you will get the number of boys and the number of girls. We need to find that number. Call that number x.
The ratio of boys to girls is:
3x to 7x
There are 3x boys and 7x girls.
The number of girls is 200 more than the number of boys.
7x = 3x + 200
Subtract 3x from both sides.
4x = 200
Divide both sides by 4.
x = 50
The number of boys is 3x, so
3x = 3(50) = 150
150 boys and 350 girls were enrolled that year.
Since a college was previously an all girls college, and then it began to allow boys to enroll, and by 2012 the ratio of boys to girls was 3 to 7, to determine, if there were 200 more girls than boys in 2012, how many boys were enrolled that year, the following cross multiplication calculation must be performed:
7 - 3 = 200 3 = X 4 = 200 3 = X 3 x 200/4 = X 600/4 = X 150 = X 150/3 = 50 (150 + 200) / 3 = 50
Therefore, 150 boys and 350 girls were enrolled that year.

Three times the sum of a number and 2 is the same as the number minus 4
Answer:
3* ( n+2) = n-4
n=-5
Step-by-step explanation:
Three times the sum of a number and 2 is the same as the number minus 4
3* ( n+2) = n-4
Distribute
3n +6 = n-4
Subtract n from each side.
3n-n +6 =n-n-4
2n +6 = -4
Subtract 6 from each side.
2n +6-6 = -4-6
2n = -10
Divide by 2 on each side.
2n/2 = -10/2
n = -5
The perimeter of a rectangle is 34 units. Its width is 6.5 units. Write an equation to determine the length of the rectangle.
Answer:
The length for a rectangle with a perimeter of 34 units and a width of 6.5 units would be 10.5 units.
Step-by-step explanation:
To find the length, you can use the equation [34 - (6.5 x 2) ÷ 2 = the length]. So, 6.5 x 2 = 13, then 34 - 13 = 21, finally, 21 ÷ 2 = 10.5 . So the length of the rectangle is 10.5 . To double check, (6.5 x 2) + (10.5 x 2) (=) 34. So this answer is correct.

To find out the sales tax percentage, first find the amount paid in taxes by subtracting the original price from the total price. Then divide this tax amount by the original price and multiply by 100 to get the percentage, which is 4% in this case.
Explanation:To determine the sales tax percentage charged on the coffee table, we first calculate the total amount of sales tax paid. We subtract the original price of the table ($59) from the total amount paid with tax ($61.36) to find the amount of tax paid.
$61.36 - $59.00 = $2.36
Now, we'll convert the sales tax into a percentage of the original price. We do this by dividing the sales tax amount by the original price and then multiplying by 100 to get the percentage.
$2.36 ÷ $59 = 0.04 (rounded to two decimal places)
0.04 × 100 = 4%
Therefore, the sales tax percentage on the coffee table is 4%.

Answer:
<1 = 30
<2= 41
<3 = 96
Step-by-step explanation:
Angle 1 ,66 and 84 form a triangle and triangles add to 180 degrees
<1 + 66 + 84 = 180
Combine like terms
<1 +150 = 180
Subtract 150 from each side
<1 + 150 -150 = 180-150
<1 = 30
Angle 3 and 84 form a straight line. A straight line is 180 degrees.
<3 + 84 =180
Subtract 84 from each side
<3 +84-84 = 180 - 84
<3 = 96
<2 , <3 and 43 form a triangle which adds to 180 degrees,
<2 + <3 + 43 = 180
We have already found <3 to equal 96 degrees
<2 + 96+43 = 180
Combine like terms
<2 +139=180
Subtract 139 from each side.
<2 +130-139 = 180-139
<2 = 41

Which tables represent constant functions?
A function is a law that tells you how to associate inputs (x values) and outputs (y values).
In the case of constant functions, it doesn't matter which input you choose, the ouput must always be the same.
So, a constant function has always the same output (y values) for every input (x values) you feed.
Answer:
Third and last choices represent constant functions.Step-by-step explanation:
A constant function refers to those functions that only have one variable, which is constant. For example, x=2, y=4, x=-1, are constant function, because they don't variate.
From the given tables, the third and last choices are constant function, because you can observe that one variable doesn't variate. The third function has y=3 as the constant value, and the last table has y=-1 is the constant function.
Therefore, the right choices are third and last table.
Aria walked down a trail into a valley. V(d) models Aria's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail. What does the statement V(3)<3 mean?
Answer:
When Aria had walked 3km along the trail, her vertical distance from the top of the valley was less than 3 km
Step-by-step explanation:
Remember that V(d) denotes Aria's vertical distance from the top of the valley V after she has walked d kilometers along the trail.
This means that V(3) is Aria's vertical distance from the top of the valley after she has walked 3km.
Therefore, V(3)<3 means that Aria's vertical distance from the top of the valley after she has walked 3km, is less than 3km
In other words, the statement means that when Aria had walked 3km along the trail, her vertical distance from the top of the valley was less than 3km
V(3) < 3 means Aria's vertical distance from the top of the valley is less than 3 kilometers after walking 3 kilometers along the trail. It shows her descent into the valley is not more than 3 kilometers vertically at that point.
The inequality V(3) < 3 means that after Aria has walked 3 kilometers along the trail, her vertical distance from the top of the valley is less than 3 kilometers. In other words, Aria has descended into the valley, but her descent after 3 kilometers along the trail is not greater than 3 kilometers vertically. This provides a way to understand her position relative to the top of the valley based on the distance she has walked.

Which lines are parallel if m angle 1= m angle 2 ?
how do the graphs of the function f(x)=(3/2)x and g(x)=(2/3)x compare
Answer:
f is a line through 0 and (2,3)
g is a line through 0 and (3,2)
Step-by-step explanation:
f and g are proportional linear functions. They each have the form y=mx+b where b=0 and m is a fraction. The m or slope tell us the form the function takes on the graph. It is a straight line through 0 with steepness m.
[tex]f(x)=\frac{3}{2} x[/tex] has steepness 3/2. Starting at (0,0) or the origin, move up three grid lines on the y-axis and then over 2 grid lines. Mark your point at (2,3). Then connect and draw arrows on the end.

Find the slope of:2y+8x=6
Answer:
-4
Step-by-step explanation:
The slope of the line given by the equation 2y + 8x = 6 is -4. This was found by converting the equation into slope-intercept form, y = mx + b.
To find the slope of the equation 2y + 8x = 6, we first need to convert it into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
Start with the given equation: 2y + 8x = 6Isolate y by subtracting 8x from both sides: 2y = -8x + 6Divide everything by 2 to solve for y: y = -4x + 3In the slope-intercept form y = -4x + 3, the coefficient of x is the slope -4.Therefore, the slope of the line is -4.

The length of a rectangular garden is represented by 3x-4 and the width is represented by 2x-5. Which of the following represents the total area of the garden
The options are
a.) 5x - 9
b.) 6x + 20
c.) 6x²- 23x + 20
d.) 6x²-14x - 9
Answer:
c.) 6x²- 23x + 20
Step-by-step explanation:
Rectangle area can be computed as length × width . The garden is a rectangle so the area can be computed by multiplying the length and the width.
Area= L × W
Length = 3x - 4
width = 2x - 5
Area = (3x - 4)(2x - 5)
Area = 3x(2x) + 3x(-5) -4(2x) -4(-5)
Note : - × - = +
Area = 6x² -15x - 8x + 20
Area = 6x² - 23x + 20
