Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.
-3x + 2y = -8
3x – 2y = 8
A. No Solutions
B. Infinitely Many Solutions
C. One Solution

B) Infinitely Many

Step-by-step explanation:

0 = 0

Step-by-step explanation:

Combine the equations

-3x + 2y = -8

3x – 2y = 8

obtaining:

-3x + 2y = -8  

3x – 2y = 8

  0 + 0 = 0

Since this is always true, this system  has an infinite number of solutions (B)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

7,24
