Answer:
b = (2A)/h
Step-by-step explanation:
With area formula for triangle: A = (1/2)*b*h
Solve for b
2*A = 2*(1/2)*b*h
2A = bh
2A / h = b
Answer:
75 degrees
Step-by-step explanation:
Complementary angles equal 90 degrees together. That is the case with angle X and Y. Set an equation to describe the situation.
Y=1/5X
X=5Y
Now, set another equation:
X+Y=90
Substitute the first equation into the second one.
5Y+Y=90
6Y=90
Y=15
Substitute this once again:
X+15=90
X=75
3/4's obviously because the percentage is bigger.

Answer:
g(x) = 7x -1
Step-by-step explanation:
The y-coordinate of a function tells how many units the function value lies above the x-axis. Translating that value down 4 units is the same as subtracting 4 from the function value.
g(x) = f(x) -4
g(x) = 7x +3 -4
g(x) = 7x -1
