Match each system with the number of solutions. 1. y = -5-x, y = x + 5 2 2. y = 4(1.2)x, y = x + 7 1 3. y = (0.5)x, y = 6 0

The reason why most of the answers regarding this problem say "all of them have only one solution" is because the x's in the equations are meant to be raised to a power.

Step-by-step explanation:

So, y=-5^-x and y=x+5 when graphed would have 0 solutions.

y=4(1.2)^x and y=x+7 would have two solutions.

And y=(0.5)^x and y=6 would have one solution.

based on context clues you gave i'm assuming the answer would be c.

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.
