So basically you use the ratio they have given you. You either multiply by 2 if image is enlarged or divide by 2 if it is reduced. (Keep in mind I got the 2 from your ratio : 1inch : 2inches) Therefore the find the original width, you multiply 10 by 2, giving you 20 inches.

Write the equation of the line that goes through the point (-2, 8) with a slope of 1/2
hram777 [196]

Answer:

The answer is Y = 1/2x + 9

Step-by-step explanation:

The general equation with a slope and intercept is:

y=mx+b

We are given a slope of 1/2, which represents the "M" part of the equation.

So we have:

Y = 1/2x + b

We do not know what "b" is, so the equation is not complete.

We plug in "-2" for X and "8" for Y:

8 = 1/2 (-2) + b

b = 9

So, the full equation is: Y  = 1/2x + 9

Alona [7]
<span>Let's find out the ball's acceleration V^2 = U^2 + 2as Where the distance S = 6 feet and U = 45. Suppose he just took off so V = 0 and we are left with U^2 =2as (45)^2 = 2a(6) a = 2025/12 = 168.75 ft/s^2 Also S = ut + 1/2 at^2 Here S = 5ft and U= 0; a = 168.75. So we have 5 = (1/2) * 168.75 * t^2 So we have 5 * 2 = 168.75 t^2 T^2 = âš 10/ 168.75 = 0.00596 = âš0.006 T = 0.0077s</span>
