Answer:
Divide by 2
Then subtract 4
Step-by-step explanation:
Let y = 2(x+4)
Exchange x and y
x = 2(y+4)
We want to solve for y
Divide each side by 2
x/2 = y+4
Then subtract 4 from each side
x/2 -4 =y
The inverse is x/2 -4
Answer:
We can factor the quadratic function into (2x + 7)(x + 1) and this way, the terms sum to 2x^2 + 9x + 7. Looking at the 2 factors 2x+7 and x+1, the way to find the zeros is to set both of these expressions equal to 0. Therefore we have: 2x+7=0

Answer:
y=14
Step-by-step explanation:
- the triangle is equilateral triangle
- angle A = angle B
- so we immediately got the answer for x.. x=25
- so 180°-100°=80°
- 5y+10°=80°
- 5y=80°-10°
- 5y=70°
- y=70°/5
- y=14
I think its A but not positive
