Stray from the side farthest to the left you will eithe go up or you kill either go over. If you go over to the left it's wrong. But if you go to the right it's correct but if the line is a negative and you end up going down the slop make sure to put your negligible sign.
Step-by-step explanation:
A. D(t) = -25t + 160
this is the correct answer because if you substitute 3 you get 85
Answer:
x = 72
Step-by-step explanation:
Make the problem simpler by eliminating the fractional coefficients:
x-9= 1/4x + (1/4x + 12) + (1/4x - 3), when multiplied by 4, becomes:
4x - 36 = x + x + 48 + x - 12
Summing up all the x terms, we get:
4x - 2x - x = 48 - 12 + 36
Then x = 72
The correct answer is -2 I just took the test.
