Answer:
x=8
Step-by-step explanation:
a
x+2=7x-3
x+7x=3-2
8×= 1
×=8
b
13y+25=8y+5
13y+8y= 25+5
21y=30
y= 30-21
y=11
Looks like all you have to do it multiply the numbers together; there is no application of the Distributive Property to these problems.
Answer:
A. y = 80x
B. g(x) = 80x
C. To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.
Step-by-step explanation:
Part A:
To write an equation, use y= mx where m is the slope, x is the number of days, and y is the rent cost.
x and y remain the same in the equation.
To find m, use the slope formula with (5,465) and (7, 625).
It costs $80 a day.
The equation is y = 80x.
Part B:
Function notation replaces Y as g(x). So the equation is g(x) = 80x.
Part C:
To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.
Since EF=FG, you can set 6x - 10 = to 3x + 11
Then add like terms
so,
Now you can divide by 3 to get
:)
then put it back into
so,
