Answer:
$7.50
Step-by-step explanation:
For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: total cost
We write the algebraic expression that models the problem.
We have then:

Simplifying we have:

Then, by the time the cost is equal to $ 300 we have:

From here, we clear the value of x.
Answer:
an algebraic expression for the problem is:

Answer:
The coordinates of B are (-5, -1).
Step-by-step explanation:
You can make a linear relationship. Since AB is <em>1 unit down and 3 units to the left of</em> A, B must be <em>1 unit down and 3 units to the left of</em> AB.
Answer:
$15
Step-by-step explanation:
12/8 = 1.5 = 1.50 per cookie
1.50* 10 = 15
x² + 5x - 6 can be expressed as (x + 6)(x - 1).
