The old rate of pay is x and the new rate is y then we have:
y = 2x + 7
Y = 21
PART 1: 21 = 2x+7
Subtract 7 from each side:
14 = 2x
Divide both sides by 2:
X = 14 / 2
X = 7
PART 2: The internship pays $7 per hour.
Answer:
a. subtract 7 from 10
Step-by-step explanation:
parenthesis goes before everything in this equation
X(7x+3)=0
x=0
or
7x=-3
x=-3/7
so,
(0,0) or (-3/7,0)
