Answer:

A

Step-by-step explanation:

3x+2y=15

-3x

2y=15-3x

divide by 2

y=-3/2x+7.5

Parallel Line = Same Slope

y=-3/2x+b

substitute (5,2)

2=-3/2(5)+b

2=-7.5+b

   +7.5

9.5=b

Final Equation: y=-3/2x+9.5

Lana needs to first convert the equation to slope-intercept form, and then use the parallel line's slope with the provided point in the point-slope formula to find her line's equation.

The correct option for Lana to find an equation for a line that passes through the point (5, 2) and is parallel to the given equation 3x + 2y = 15, is option A.

First, Lana needs to write the given equation in slope-intercept form which is y = mx + b, where m is the slope and b is the y-intercept. To do this, she needs to rearrange the equation by subtracting 3x from both sides and dividing by 2, which gives y = -1.5x + 7.5.

Parallel lines have the same slope, so the slope, m, of Lana's line is -1.5. Now, she uses the point-slope form of a linear equation which is y - y1 = m(x - x1), where (x1, y1) is the point the line passes through. Substituting the point (5, 2) and slope -1.5 into this equation, Lana gets y - 2 = -1.5x + 7.5.

She rearranges this to get her final equation.

Answer (2 answers):

x = -2/5,  x = -14/5

Step-by-step explanation:

First step is to try and get the absolute value by itself on one side and everything else that's not inside the absolute value on the other side.

9|5x+8|=54

|5x+8| = 54/9

|5x+8| = 6

Remember how absolute values turn everything positive? For example

|-4|=4, but |4|=4 as well. So we must do the same to our problem by splitting up the absolute equation into two parts.

|5x+8| = 6     and     |-(5x+8)| = 6

now solve the first equation.

(Just remove the absolute value sign and solve it normally)

5x+8 = 6

5x = -2

x = -2/5

Now solve the other equation

-(5x+8) = 6

-5x - 8 = 6

-5x = 14

x = -14/5

Answer: Domain = { -3 , 6 , 5 , -6}

Range = { 7 , 2 , -1 , -6 }

Step-by-step explanation:

considering the points given

[tex]x_{1}[/tex] = -3                                [tex]y_{1}[/tex] = 7

[tex]x_{2}[/tex] = 6                                [tex]y_{2}[/tex] = 2

[tex]x_{3}[/tex] = 5                                [tex]y_{3}[/tex] = -1

[tex]x_{4}[/tex] = -9                               [tex]y_{4}[/tex] = -6

This shows that that is relationship between the values of x and the values of y.

All the values of x represent the domain and all the values of y represent the range.

Therefore :

Domain = { -3 , 6 , 5 , -6}

Range = { 7 , 2 , -1 , -6 }

Answer:

190 km an hour

Step-by-step explanation:

old: $16

new: $20

percent increase

-> formula: (new-old / old) x 100

(20-16 / 16) x 100

4/16 x 100

0.25 x 100

answer: 25% increase

According to the question,

Old selling price,

New selling price,

We know the formula,

→ [tex]Percent \ increase = \frac{New \ selling \ price- Old \ selling \ price}{Old \ selling \ price}\times 100[/tex]

By putting the values,

                               [tex]= \frac{20-16}{16}\times 100[/tex]

                               [tex]= \frac{4}{16}\times 100[/tex]

Answer:

45 degrees

Step-by-step explanation:

because 2 and 5 are vertical angles they are therefore congruent by definition, 5 is half of one and one is a right angle so measure angle 2 = 45 degrees

Answer:

50

Step-by-step explanation:

The total of all 6 angles make a circle, which equals 360°. Using the information below the figure,

2 * m∠5 = 90°, since 2 * m∠5 = m∠1 and ∠1 is a right angle.

Because ∠1, ∠5, and ∠6 are on one side of line L, they must equal 180°, and if ∠1 equals 90°,

m∠5 + m∠6=90°.

Since 2 * m∠5=m∠1 and m∠1=90°, m∠1 must be 45°. And by Transitive Property, m∠6 also equals 90°.

If the total measure of the angles is 360° and ∠1, ∠5, and ∠6 add up to 180°, ∠2, ∠3, and ∠4 must also add to 180°.

m∠6=m∠3 - 20°. We know that m∠6 is 45°, so we put that into an equation. I am going to use x as the measure of ∠3.

45=x-20  >>>  20+45=x-20+20  >>>  20+45=x  >>>  65=x  >>>  x=m∠3  >>>  m∠3=65

m∠3=m∠4, so m∠3+m∠4=65+65, or 130. And like I said above, ∠2, ∠3, and ∠4 must add to 180°. 180 minus 130 (the measure of ∠3 + ∠4) = 50, which has to be the measure of ∠2

Answer:

1640.

Step-by-step explanation:

1640 would be your best option. As you are much higher than average. 2060 would not be a better option as you are below average in this case.

Answer:2060

Step-by-step explanation: your closest to 2060

Using the cross product property on this proportion gives us the following equation:

20 (2x - 9) = 10 (9)

Use the distributive property and multiply

40x - 180 = 90

Add 180 to both sides

40x = 270

Divide 40 from both sides

x = 270/40

Simplify fraction

x = 27/4

The cross product is a type of multiplication between vectors that results in a vector product. It has the distributive property and is anticommutative.

The cross product is a type of multiplication between vectors that results in a vector product. It is denoted by the symbol A x B and is also known as the vector product.

The cross product has the distributive property, which allows us to distribute a vector across the sum of two other vectors. For example, A x (B + C) = (A x B) + (A x C).

The cross product is anticommutative, meaning that the order in which we multiply two vectors matters. A x B = -B x A.

Answer:

[tex]5\frac{2}{3}[/tex] miles.

Step-by-step explanation:

Kevin recorded the distances he ran last week in the table attached to this question.

Now, the total number of miles he ran on Monday through Wednesday is the same as the total number of miles he ran on Thursday and Friday.

Hence, {x + (x + 9) + (x + 4)} = {2x + (4x - 2)}

⇒ 3x + 13 = 6x - 2

⇒ 9x = 15

⇒ [tex]x = \frac{15}{9} = \frac{5}{3}[/tex]  

Therefore, he ran on Wednesday = x + 4 = [tex]\frac{5}{3} + 4 = \frac{17}{3} = 5\frac{2}{3}[/tex] miles. (Answer)

Answer: 9 miles

Step-by-step explanation:

x + x + 9 + x +4 = 2x + 4x-2

Collecting like terms

x + x + x +9 + 4 = 2x + 4x -2

Collect like terms

3x +13 = 6x -2

3x - 6x = -2 -13

-3x = -15

Divide both side by -3

x = 5

Therefore ; total number he ran on Wednesday

x + 4

If x = 5

Therefore total number he ran on Wednesday = 5+4

Sybil's profit for selling n watermelons is represented by the function P = 2n - 15, which is the result of subtracting her cost function from her revenue function.

The function that represents Sybil's profit, P, for selling n watermelons is found by calculating the difference between her revenue and her costs. The profit function, therefore, is the revenue function R = 6n minus the cost function C = 4n + 15. Executing the subtraction, we get:

P = R - C

P = 6n - (4n + 15)

P = 6n - 4n - 15

P = 2n - 15

This function represents the profit made on selling n watermelons.

Final answer:

The function representing Sybil's profit for selling n watermelons is P = 2n - 15.

Explanation:

Profit can be calculated by subtracting the total cost from the total revenue. In this case, the total revenue function is R = 6n and the total cost function is C = 4n + 15. To find the profit function, we subtract the total cost function from the total revenue function:

P = R - C

P = 6n - (4n + 15)

P = 2n - 15

Therefore, the function representing Sybil's profit for selling n watermelons is P = 2n - 15.

Answer:

41.24 cm²

Step-by-step explanation:

Here is the complete question:  A 3 cm by 3 cm rectangle sits inside a circle with radius of 4 cm. What is the area of the shaded region?

Given: measurement of rectangle is [tex]3\ cm\times 3\ cm[/tex]

          Radius of circle is 4 cm.

We can find the area of shaded region by subtracting area of rectangle from area of circle.

First, lets find the area of rectangle

Formula; Area of rectangle= [tex]length\times width[/tex]

Area of rectangle= [tex]3\ cm\times 3\ cm= 9\ cm^{2}[/tex]

∴ Area of rectangle= 9 cm²

Now, finding the area of circle.

Formula: Area of circle= [tex]\pi r^{2}[/tex] (∵ r is radius)

Area of circle= [tex]3.14\times 4^{2} = 3.14\times 16[/tex]

∴ Area of circle= 50.24 cm²

Next solving to find area of shaded region.

Area of shared region= [tex]\textrm{Area of the circle} - \textrm{Area of the rectangle}[/tex]

Area of shaded region= [tex]50.24\ cm^{2} - 9\ cm^{2} = 41.24\ cm^{2}[/tex]

∴ Area of shaded region= 41.24 cm²
