4 is 16.3, I don't know 5 or 6, 7 is 176, I don't know 8 or 9, 10 is 8.1, I don't know 11, and 12 is 48.
(I used a calculator, lol)
i) first you combine the like terms; 3x² and x², then 4x and -8x, then -7n and -1.
Then you would get 4x²-4x-8.
You then cannot simplify further. so your answer would be 4x²-4x-8.
Answer: y = 5x + 13
<u>Step-by-step explanation:</u>
Parallel means it has the same slope.
Given line y = 5x + 5 --> the slope is 5, so parallel slope is 5
Use the Point-Slope formula: y - y₁ = m(x - x₁) such that
y + 2 = 5(x + 3) <em>input m and (x₁, y₁) into the Point-Slope formula</em>
y + 2 = 5x + 15 <em>distributed</em>
y = 5x + 13 <em>subtracted 2 from both sides</em>
I think the answer is 2.4 x 10^3
Hope this helped.
