Select the slope and y-intercept of the relationship shown in the table

Answers

Answer:

slope = 0.05, y-intercept = 2,000

Hence, option A is true.

Step-by-step explanation:

x                              y

10, 000                   2,500

20, 000                   3,000

30, 000                    3, 500

Taking two points (10000, 2500) and (20000, 3000) to find the slope between the points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{3000-2500}{20000-10000}[/tex]

[tex]m=\frac{1}{20}[/tex]

[tex]m=0.05[/tex]

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where 'm' is the slope and 'b' is the y-intercept

substituting the point (10000, 2500) and m=0.05 in the slope-intercept form

[tex]y=mx+b[/tex]

[tex]2500\:=\:0.05\left(10000\right)+b[/tex]

[tex]500+b=2500[/tex]

[tex]b=2000[/tex]

Thus, the y-intercept is: b=2000

Thus,

slope = 0.05, y-intercept = 2,000

Hence, option A is true.

Write an equation of the parabola that passes through the point (62,−490) and has x-intercepts −8 and 72. Then find the average rate of change from x=−8 to x=2.

Answers

Answer:

y =  0.7(x^2 - 64x - 576)

Average rate of change = -49.

Step-by-step explanation:

As the x intercepts are -8 and 72 we can write the equation

y = a(x + 8)(x - 72)     where a is some constant to be found.

As it passes through point  (62, -490) we have, substituting:

-490 = a(62+8)(62-72)

-490 =  - 700a

a = 0.7

So the equation of the parabola

y = 0.7(x + 8)(x - 72) or

y =  0.7(x^2 - 64x - 576).

Average rate of change between x = -8 and x = 2

=  [0.7(2+ 8)(2 - 72) -  0.7(-8+8)(-8-72)] / (2 - -8)

= -490 - 0 /10

= -49

What is the product of 60?

Answers

We divide 60 by 2 as many times as possible to get 60 = 15 x 2 x 2. 2 is a prime number so we don't need to break the 2's down any more. Instead we break 15 down. 15 doesn't divide by 2 so we try the next prime number: 3 Divide 15 by 3 to get 15 = 5 x 3, and so 60 = 5 x 3 x 2 x 2.

Answer:

the product of 60 is 5×3×2×2

Please help ASAP !! I’ll give brainleist

Answers

Answer:

x=12

y=9

Step-by-step explanation:

Since the two triangles are equal, the hypotenuse of each are equal as well, meaning 2x is equal to x+12.  2 times 12 equals 24, and 12+12 also equals 24.

the shorter sides are also equal to each other, so (y+5) equals (2y-4).  9+5 equals 14, and 2 times 9 minus 4 also equals 14.

Reflect triangle ABC over the x-axis. Then translate the new triangle 5
units to the left. What are the coordinates of the vertices of the final image?

Answers

Answer:

The coordinates of the vertices of the final image will be:

A''(-6, 8), B''(-7, -2), and C''(0, -2)

Hence, option (B) is true.

Step-by-step explanation:

Given the triangle with the vertices

A(-1, -8)B(-2, 2)C(5, 2)

We know that when we reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate reverses its sign.

Thus,

The rule of reflection across the x-axis:

(x, y) → (x, -y)

so

A(-1, -8) → A'(-1, -(-8)) = A'(-1, 8)

B(-2, 2) → B'(-2, -2) = B'(-2, -2)

C(5, 2) → C'(5, -2) = C'(5, -2)

Then, translate the new triangle 5  units to the left

Rule of translating 5 units to the left

(x, y) → (x-5, y)

so

A'(-1, 8) → A''(-1-5, 8) = A''(-6, 8)

B'(-2, -2) → B''(-2-5, -2) = B''(-7, -2)

C'(5, -2) → C''(5-5, -2) = C''(0, -2)

Therefore, the coordinates of the vertices of the final image will be:

A''(-6, 8), B''(-7, -2), and C''(0, -2)

Hence, option (B) is true.

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Step-by-step explanation:

Given

Stores and Parking Lots

Required

Determine the area as a sum of area of stores and area of parking lots

First, calculate the area of the stores

The dimension of store A is: 25 by 10

The dimension of store B is: 25 by w

The dimension of stores A and B (as an entity) is: 25 by 10 + w

The area is then calculated as:

[tex]Area = 25 * (10 + w)[/tex] -------- A1

Next, calculate the area of the parking lots

The dimension of parking lot A is: 13.5 by 10

The dimension of parking lot B is: 13.5 by w

The dimension of parking lots A and B (as an entity) is: 13.5 by 10 + w

The area is then calculated as:

[tex]Area = 13.5 * (10 + w)[/tex] -------- A2

The area of the shopping center is then calculated as:

[tex]Area = A_1 + A_2[/tex]

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]
