y = 3x :) hope this helps!
Answer:
7. 80 miles
8. F
Step-by-step explanation:
7. Jorge leaves 2 hours early, and is going 20 miles per hour. So before Marcos starts going, Jorge has gone 40 miles (2*20). Then, 1 hour later, Jorge is at 60 miles and Marcos is at 40 (because he goes 40 miles per hour in his car). Another hour later, Jorge is at 80 (60+20) and Marcos is at 80 as well (40 + 40). They will both have gone 80 miles when Marcus catches up.
8. You want to get <em>a</em> isolated.
A = h/2(a + b)
First, multiply both sides of the equation by the reciprocal of h/2.
2A/h = a + b
Then, subtract b from both sides.
2A-b/h = a
Answer:
The answer is: 
Step-by-step explanation:
We are given: 
and 
We need to find 
.
Simply divide 
and 
.
Which equates to:
This cannot be simplified further, so it is the answer.
D. The y-intercept of the function is (0, 5) and e. The function crosses the x-axis twice are true
