4y - 8 > 10
add 8 to both sides
4y > 18
Divide both sides by 4
y > 18/4
y > 9/2
y > 4.5
Answer:
128
Step-by-step explanation:
8 - 5 x 3 x -2^3
8 - 5 x 3 x -8
8 - 15 x -8
8 - -120
128
It is 4:2
Since it is similar AB is double the size of AB' and BC is double the size of BC'. so 4:2 4 is double the size of 2.
Question 8 should be y=-5/2x-1. And question 9 should be y=1/2x-7.
