Y=2x+6
gradient is found from the formula,

y intercept is found by subbing the values of (-1,4) into the equation y=2x+c
Answer:
-15
Step-by-step explanation:
g(x) = 3x + 3
Let x = -6
g(-6) = 3*-6 + 3
= -18 +3
= -15
Answer: 1, 3, 4, and 5 but stick with 1, 3, and 4
Step-by-step explanation:
just use a calculator to find 3, 4 is easy because red normally has more, and one is just an estimate
Writing the two equations in full and subtracting R(x) from W(x) to arrive at D (x) gives the answer. This is shown below;
W(x) = 0.002x^3 - 0.01x^2 + 0x + 0
R (x) = 0x^3 + x^2 - 4x +13 -
-----------------------------------------------
D(x) = 0.002x^3 -1.01x^2 + 4x - 13
