Your doing the Distributive Property. So in this equation your distributing the first 2 on the outside of the parenthesis, so this first section of your problem after distributing is 6n+8. Next distribute the -2 to the 2n and 5. DON'T FORGET THE NEGATIVE. So it would look like 6n+8-4n-10. Then combine like-terms. so 6n-4n = 2n. Then 8-10=-2. Your final answer should be
2n-2.
Hope this helped.
Answer:
Slope = 1/2
y-intercept = 30
Equation : y = 1/2x + 30
D. 150 miles
Step-by-step explanation:
We can use the two visible points you marked on the graph.
They are (0,30) which is also the y-intercept and (20,40).
Calculate change of y over change of x.
10/20 or 1/2
So the slope is 1/2 and the y-intercept is 30.
Therefore, using y = mx + b form, the equation is y = 1/2x + 30
Then, to find how many miles you drove if the cost was $105, we can plug in 105 for y in the equation.
105 = 1/2x + 30
75 = 1/2x
x = 150
