Answer:
30%
Step-by-step explanation:
the first solution -30% will be 45% and the second solution added by 30% will be 45%
In order to find which one is or isn't, you need to solve for the value of 'x'.
2x + 15 = 35
2x = 20
x = 10
Substitute x =10, into equation. If each side are not the same (i.e. 0=2), then that's the equation that is not equivalent,
Answer is B
Double check this. Chur! :)
Hope this makes sense.
<u>SOLUTION:</u>
General Equation: y = mx + b
.
Substitute slope = -2 into the equation:
y = -2x + b
.
Find the y-intercept:
4 = -2(-3) + b
4 = 6 + b
b = -2
.
Substitute b = -2 into the equation:
y = -2x - 2
.
Answer: y = -2x - 2
Answer:
D
Step-by-step explanation:
Because A isn' at all right and B, and C equal the same but D = 36 So the sides are 18 each side.
I’m also struggling with that but it’s the perimeter of a right triangle
