Answer:
slope = 7/2 or 3.5 as a decimal.
y-intercept = 1 or (0, 1) in coordinate form.
Answer:
$3.50
Step-by-step explanation:
Let x be the cost of per gallon gas.
We have been given that it costs Raquel 5$ in tolls to drive to work and back each day, plus she uses 3 gallons of gas. It costs her a total of 15.50$ to drive to work and back each day.
We can represent this information as:

Therefore, Raquel is paying $3.50 for per gallon gas.

<h3>Because A. Is not pentomino </h3><h3>C. Is not pentomino</h3><h3>D. There are no pentomino</h3>
Answer:
The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.
Step-by-step explanation:
I assume an x is missing, and the function is h(x) = -3x^2 + 30x + 225
You want to know the number of days in which the function value is zero.
-3x^2 + 30x + 225 = 0
Divide both sides by -3.
x^2 - 10x - 75 = 0
(x - 15)(x + 5) = 0
x - 15 = 0 or x + 5 = 0
x = 15 or x = -5
We discard the negative solution.
Answer: The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.
