Answer:
Two extraneous solutions
Step-by-step explanation:
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
The number of followers is decreasing
Step-by-step explanation:
The function is decreasing over time since the base of the exponent is less than 1. The value is greater when t is 0 and decreases as t increases.
SOLUTION
If the table represents an inverse variation, it means that y is inversely proportional to x, written as

Removing the proportionality sign and introducing a constant k, we have

In the first column, we have x = -4 and y = 3.5. Substituting these values for x and y, we have

So, if it's an inverse variation, the relationship would be

In the second column, x = -2 and y = 7.
Now lets substitute the value of x for -2. If we get y to be 7, then the relationship is an inverse variation
We have

Since we got y = 7, the relationship is therefore an inverse variation.
The constant k = -14
The equation for the inverse variation is
Answer:
one card takes 1/12 of an hour or 60/12=5 minutes.
she has 3/4 of an hour or 60×3/4=45 minutes
number of cards she can make =45/5=9
