Answer:

Y = 2.5X + 8

Y: height (in feet)

X: time (in years)

Step-by-step explanation:

Height = 8 + 5(t/2)

= 8 + 5t/2

Height = 8 + 2.5t

Y = 2.5X + 8

Find slope of the graph 9x-3y=15
LekaFEV [45]
<h3><u>Explanation</u></h3>
  • Convert the equation into slope-intercept form.

y = mx + b

where m = slope and b = y-intercept.

What we have to do is to make the y-term as the subject of equation.

9x - 3y = 15 \\ 9x - 15 = 3y \\  \frac{9x - 15}{3}  = y

  • Simplify

\frac{9x}{3}  -  \frac{15}{3}  = y \\ 3x - 5 = y  \\ y = 3x - 5

From y = mx+b, the slope is 3.

<h3><u>Answer</u></h3>

\large \boxed {slope = 3}

A local carpet company has been hired to carpet a planetarium which is in the shape of a circle. If the radius of the planetariu
dem82 [27]

We are given radius = 6 yards

area of circle = pi * r * r = 3.14 * 6*6 = 113.04 yard square

cost of carpet is $14 per square yard

cost of 113.04 square yard = 14*113.04= 1582.56 dollars

Answer: cost to carpet the planetarium is $1582.56

The coordinates of the image of line segment RT are R'(-2,-4) and T'(4.4). The image was produced by a dilation with a scale fac
Daniel [21]

Given the coordinates of the image of line segment RT to be R'(-2,-4) and T'(4.4), if the image produced was dilated by a scale factor of 12 centered at the origin, to get the coordinate of the end point, we will simply multiply the x and y coordinates of by the factor of 12 as shown:

For R' with coordinate R'(-2,-4), the coordinates of endpoint of the pre-image will be:

R = 12R'

R = 12(-2, -4)

R = (-24, -48)

For T' with coordinate T'(4,4), the coordinates of endpoint of the pre-imagee will be:

T = 12T'

T = 12(4, 4)

T = (48, 48)

Hence the coordinate of the endpoint of the preimage will be at R(-24, -48) and T(48, 48)
