32.50-18.50=14
he spent $14 on gas, but we want how many gallons, one gallon is 3.50
so 14/3.50=4
She put 4 gallons in the can
Answer:
(y - 6) = 3/5(x - 5)
Step-by-step explanation:
First, let's look at what point-slope form is: (y - y₁) = m(x - x₁)
Let's plug in the vallues we know.
m is the slope: 3/5
x₁ is 5
y₁ is 6
Therefore:
(y - 6) = 3/5(x - 5)
This is your equation.
Hope this helps!

Its called a constant
Answer:
Step-by-step explanation:
First we need the find the set of x such as 2x + 3 >= -3
2x + 3 >= -3 [Sum -3 in both sides]
2x + 3 - 3 >= - 3 - 3
2x >= -6 [Now, divide both sides by 2]
2x / 2 >= -6/2
x >= - 3
So, for every x>= -3 we have that 2x + 3 >= -3
Now we do the same with the other ineq:
5x-2 < 3 [sum 2 in both sides]
5x - 2 + 2 < 3 + 2
5x < 5 [divide by 5 in both sides]
5x / 5 < 5 / 5
x < 1
So, for every x<1 we have 5x-2<3
Then our set it the intersection of both of the previous sects, it is:
(x<1)intersect(x>=-3):
Solution: -3 =< x < 1
