Answer:
x = 8
Step-by-step explanation:
Set 2x + 3 = 3x - 5
Solve for x
x = 8
Answer:
(x-8)^2+(y-16)^2 = 4
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2+(y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-8)^2+(y-16)^2 = 2^2
(x-8)^2+(y-16)^2 = 4
Answer:
712
Step-by-step explanation:
So what you do is you have to substitute -9 for a and -4 b.
7(-4)^2 +5((-9)(-4)-6)=
=7(16)+5(30)=
=112+600=
=712
Answer:
25
Step-by-step explanation:
Those parallel lines tell us our triangles are similar. So that means the corresponding sides are proportional.
So we have that x corresponds to x+15 and
40 corresponds to 24+40.
So we have this proportion to solve:
![\frac{x}{x+15}=\frac{40}{24+40}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bx%2B15%7D%3D%5Cfrac%7B40%7D%7B24%2B40%7D)
Let's simplify what we can:
![\frac{x}{x+15}=\frac{40}{64}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bx%2B15%7D%3D%5Cfrac%7B40%7D%7B64%7D)
Cross multiply:
![(64)(x)=(x+15)(40)](https://tex.z-dn.net/?f=%2864%29%28x%29%3D%28x%2B15%29%2840%29)
Multiply/distribute:
![64x=40x+600](https://tex.z-dn.net/?f=64x%3D40x%2B600)
Subtract 40x on both sides:
![24x=600](https://tex.z-dn.net/?f=24x%3D600)
Divide both sides by 24:
![x=\frac{600}{24}=25](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B600%7D%7B24%7D%3D25)
x=25
