Answer:
Vertically opposite angles are equal.
Therefore,
![(4x + 7) = 5(x - 4) \\ 4x + 7 = 5x - 20 \\ \boxed{x = 27}](https://tex.z-dn.net/?f=%284x%20%2B%207%29%20%3D%205%28x%20-%204%29%20%5C%5C%204x%20%2B%207%20%3D%205x%20-%2020%20%5C%5C%20%20%5Cboxed%7Bx%20%3D%2027%7D)
<h3><u>x=27</u> is the right answer.</h3>
Answer:
1.8
Step-by-step explanation:
-2 1/4 x -4/5 = 9/5
= 1 4/5
= 1.8
Substitute y
6x + 5(2x – 14) = -6
use distributive property
6x + 10x – 70 = -6
add terms together
16x = 64
isolate x
16x/16 = 64/16
x = 4
to find value of y, use your x value in the second equation
y = 2(4) – 14
y = -6
Verify you are correct
6(4) + 5(-6) = -6
Answer:
![\boxed{\sf \ \ \ x=-5 \ \ \ or \ \ \ x=-1 \ \ }](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%20%5C%20%5C%20%5C%20x%3D-5%20%5C%20%5C%20%5C%20or%20%5C%20%5C%20%5C%20x%3D-1%20%5C%20%5C%20%7D)
Step-by-step explanation:
![x^2+6x+5 = x^2+x+5x+5 = x(x+1)+5(x+1)=(x+5)(x+1)](https://tex.z-dn.net/?f=x%5E2%2B6x%2B5%20%3D%20x%5E2%2Bx%2B5x%2B5%20%3D%20x%28x%2B1%29%2B5%28x%2B1%29%3D%28x%2B5%29%28x%2B1%29)
so
![x^2+6x+5 = 0 (x+5)(x+1)=0\\\\ x = -5 \ or \ x=-1](https://tex.z-dn.net/?f=x%5E2%2B6x%2B5%20%3D%200%20%3C%3D%3E%20%28x%2B5%29%28x%2B1%29%3D0%5C%5C%5C%5C%3C%3D%3E%20x%20%3D%20-5%20%5C%20%20or%20%5C%20x%3D-1)
hope this helps
