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
Hello!
First of all, we can see that our y-intercept is 0. As you can see, for every 1 x value, we have 3 y values. We divide, giving us a slope of 3.
Therefore, our equation is y=3x.
I hope this helps!
Answer:
x=1 and x=-1/3
Step-by-step explanation:
Therefore, x=1 and x=-1/3
The correct answer for this question is 11 - 13i.
This is how to answer this one:
(7 - 3i) (2 - i)
= [ (7*2) - (3i*2) - (7*i) + (3i*i) ]
Get the product of each term
= (14 -6i - 7i + 3i^2)
Group similar terms
= 14 - 13i - 3
Simplify.
= 11 - 13i
Side solution:
i = square root (-1)
i^2 = -1
