Answer:
Substituting x= 2y-2 in 5x
5(2y-2)
10y-10
10(y-1)
Answer:
x = 8
Step-by-step explanation:
As the triangle has 2 congruent angles, this means that their corresponding sides are of equal measure.
Therefore, -4 + 2x = 12
Add 4 to each side: 2x = 16
Divide both sides by 2: x = 8
PEMDAS is the steps to do Order of operations...
P- parentheses
E- exponents
M- Multiplication
D-Division
A- Addition
S- Subtraction
You do p first e next then either m or d then a or s
F(x) = -5x
f(-3) = -5(-3)
f(-3) = 15
---
g(x) = 2x - 1
g(4) = 2(4) - 1
g(4) = 8 - 1
g(4) = 7
Answers:
f(-3) = 15
g(4) = 7
Hope this helps.
EDIT:
Order of operations doesn't matter in addition. So you can add them in any order.
