distribute each bracket, multiplying the terms in the bracket by the value outside the bracket.
= 3g + 15 - 3g - 18 → ( collect like terms)
=(3g - 3g) + (15 - 18) = 0 + ( - 3) = - 3
10^2 is 10×10 which is 100
4^2 is 4×4 which is 16
so it simplifies to 100-16×2. By Order Of Operations, parentheses, exponents, multiply and divide, add and subtract 100-16×2 makes 100-32 which is 68
Answer:
The slope represents the cost per gallon for heating oil while the y-intercept represents the fee for heating oil.
X intercept = -1, y = 0 (-1, 0)
<span>y intercept = 2, x = 0 (0, 2)
</span>
slope between (-1, 0) and (0, 2):
slope = (2 -0)/(0 - -1) = 2/1 = 2, m = 2
Using point (-1, 0) x₁ = -1, y₁ = 0
y - y₁ = m(x - x₁)
y - 0 = 2*(x - -1)
y = 2(x + 1)
y = 2x + 2
