M∠b = 90° - 33° = 57° ← answer
Answer:
-4
Step-by-step explanation:
The two equations you have are:
y = 3x - 7
x = 1 (this comes from the x value being 1)
To solve for y, use the substitution property of equality to replace x in the equation:
where x = 1,
y = 3(1) - 7
y = -4
To find how much time the machine that took the longer job is, you would create an equation in terms of X, the amount of time it takes one of the machines.
Please see the attached picture for the work.
51 minutes is the longer time.
34 minutes for the other machine.
It's A. When you reduce between the x exponents in the original you get an xcubed on top. In A, when you reduce between the x exponents you get xcubed on bottom and they cancel each other out.
