Answer:
<em>Martin saved $75 on the television because of the sale</em>
Step-by-step explanation:
<u>Equations</u>
Let's call x=the original price of the television (before discount).
The television had been on sale for 25% off, this means the discount was:
25% of x = 
= 0.25x
The sale price was the original price minus the discount:
x - 0.25x = 0.75x
This is what Martin paid, thus:
0.75x = 225
Dividing by 0.75:
x = 225 / 0.75
x = $300
The original price of the television was $300, and the discount was:
0.25*$300 = $75
Martin saved $75 on the television because of the sale
75%
500-125 is 375
375/500 gives 3/4 which is .75
move the decimal over to the right twice to get 75%
Answer:
-50
Step-by-step explanation:
From the graph, f(1) = -5, and g(9) = -5. Then the expression evaluates as ...
5f(1) +5g(9) = 5(-5) + 5(-5) = -25 +(-25) = -50

Answer:
The relation is a linear function with the equation: y = -6/5x + 3/5
Step-by-step explanation:
Question 5)
The given graph is a straight line.
We know that the graph of a linear function is a straight line that can be written in the form
where m is the slope and b is the y-intercept
The slope of the line can be determined by taking two points
(3, -3)
(-2, 3)
Finding the slope
From the graph, the y-intercept can be obtained by setting x=0 and check the corresponding y-value of y.
or substituting m = -6/5 and (3, -3) in the slope-intercept form to determine y-intercept 'b'.
now substituting m = -6/5 and b = 3/5 in the slope-intercept form to determine the equation of the linear function
y=mx+b
y = -6/5x + 3/5
Therefore, the relation is a linear function with the equation: y = -6/5x + 3/5
