Answer:
g(2y) = 8y^2 -3
Step-by-step explanation:
g(x)=2 x^2 -3
Let x=2y
g(2y) = 2 (2y)^2 -3
= 2 (4y^2) -3
= 8y^2 -3
7x - 35 < 2(x -5)
Use distributive property on the right side:
7x -35 < 2x - 10
Add 35 to both sides:
7x < 2x + 25
Subtract 2x from both sides
5x < 25
Divide both sides by 5
X < 5

Step-by-step explanation:
7/15 divided by 3/5
7/15 / 3/5
Keep ====> 7/15
Change =====> *
Flip ====> 5/3
Now multiply
7/15 * 5/3 = 35/45
35/45 = 7/9
Answer: 7/9
