Answer:
- 43t - 22s - 3
Step-by-step explanation:
(–45t + 53s) + (–3 – 75s + 2t)
Opening the brackets
-45t + 53s -3 - 75s + 2t
Collecting like terms
-45t + 2t + 53s - 75s -3
Simplify the expression
-43t -22s - 3
Answer:

Answer:
25 miles per gallon
Step-by-step explanation:
if you divide the number of miles(387.5) by the number of gallons (15.5) you should get 25miles per gallon
An x intercept occurs whenever y=0.
y=(x-4)(x+2)
So for y=0, x=-2 or 4, so the x-intercepts are:
(-2, 0) and (4, 0)
Only (-2, 0) is within your answer choices.
The equation of a line is y=mx+b
To find the gradient you calculate the change in Y/change in X.
To find the y-intercept you should plug it in a graphic calculator.
