Answer:
Tim has 64 dollars. I did the math and I know I'm right
Answer:
Step-by-step explanation:



Set each factors equal to zero.


The x-int is

Answer:
3x + 2y = 16
x = 2 , y = 5
Step-by-step explanation:
Given that George bought x quarts at $3.00 per quart & y quarts at $2.00 per quart and he bought 7 quarts for $16.00
Considering the total cost
3x + 2y = 16
For the cost of each
x + y = 7
solving the 2 equations simultaneously be substitution
x = 7 - y
3(7 - y) + 2y = 16
21 - 3y + 2y = 16
-3y + 2y = 16 - 21
-y = - 5
Divide both sides by -1
y = 5
x = 7 -y
x = 7 - 5
= 2
Answer:
The slope is the cost per hour.
$5 per hour
Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
in this problem
For x=32, y=-4
Find the value of the constant of proportionality k

substitute

simplify

so
The linear equation is

Find x when the value of y=0
Remember that
In a proportional relationship <u><em>the line passes through the origin</em></u>
so
If y=0
then
the value of x must be equal to zero
therefore
