(x-10)(x-4) because 4-10=6 then multiply that by 0 from 4-4
Using linear function concepts, the slope of -1 means that when one of the length/width is increased by 1, the other is decreased by 1.
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- The lengths and the widths are interchangeable, that is, either can be considered as the input or as the output.
- The slope of -1 means that when the input in increased by 1, the output is decreased by -1, that is, when one of the length/width is increased by 1, the other is decreased by 1.

Lets do this:-
A. 7 Sandwiches
18 - 7 = 11
7 × $7.75 = $54.25
7 sandwiches cost $54.25.
11 × $4.50 = $49.50
11 soups costs $49.50
49.50 + 54.25 = 103.75
A is not d answer cuz d total of d lunches came to $113.50.
B. 8 sandwiches
18 - 8 = 10
8 × $7.75 = $62
8 sandwiches cost $62.
10 × $4.50 = 45
8 soups costs $45
62 + 45 = 107
B is not d answer cuz d total of d lunches came to $113.50.
C. 9 Sandwiches.
18 - 9 = 9
9 × $7.75 = 69.75
9 sandwiches cost $69.
9 × $4.50 = 40.50
9 soups costs $40.50
69 + 40.50 = 109.5
C is not d answer cuz d total of d lunches came to $113.50.
D. 10 Sandwiches
18 - 10 = 8
10 × $7.75 = $77.75
10 sandwiches cost $77.75.
8 × $4.50 = $36
8 soups costs $36.
77.75 + 36 = <span>113.75
</span>D is not d answer cuz d total of d lunches came to $113.50.
So, based on your answer choices there is no correct choice. <span />
your answer is going to be x 22 and y 34
Answer: x = 7
Step-by-step explanation:
do opposites to both sides. what is the opposite of -5? it would be plus 5.
add 5 to both sides
3x = 21
now what is the opposite of 3 times x? 3 divided by.
divide 3 to both sides
x = 7
