Answer:
No, it is incorrect. The line should be solid, not dotted, because it's a ≤ sign, not a < sign.
Note that a change can be an increase or a decrease.
For an increase, use a positive number. For a decrease, use a negative number.
What is the change in Scott's total pay for each copy of History is Fun he sells?
What is Scott's total pay if he doesn't sell any copies of History is Fun?
Answer:
A. $80
B. $2100
Step-by-step explanation:
Given:
80x+2100=y
Rewrite the equation
y = 80x + 2100
Where,
y = Scott's total pay (in dollars)
x = number of copies of History is Fun he sells
2100 = fixed pay
A.
Since, x = number of copies of History is Fun he sells
If x = 0
y = 80x + 2100
= 80(0) + 2100
= 0 + 2100
= 2100
y = $2100
If x = 1
y = 80x + 2100
= 80(1) + 2100
= 80 + 2100
= 2180
y = $2180
change in Scott's total pay for each copy of History is Fun he sells = $2180 - $2100
= $80
B. What is Scott's total pay if he doesn't sell any copies of History is Fun?
That is, when x = 0
y = 80x + 2100
= 80(0) + 2100
= 0 + 2100
= 2100
y = $2100

Answer:
2a. (x, y) = (2, 2)
2b. (x, y) = (3, -1)
3. -5, 3, y, 5, 1
Step-by-step explanation:
The first equation defines an expression for x, so it is convenient to use that to substitute for x in the second equation.
2(3y-4) -y = 2 . . . . . substitute for x
6y -8 -y = 2 . . . . . . eliminate parentheses
5y = 10 . . . . . . . . . add 8, collect terms
y = 2 . . . . . . . . . . divide by 5
x = 3(2) -4 = 2 . . . find x using the first equation
The solution is (x, y) = (2, 2).
__
Add 3 times the second equation to the first.
(3x +2y) +3(-x +y) = (7) +3(-4)
5y = -5 . . . . . simplify
y = -1 . . . . . . . divide by 5
x = y +4 = -1 +4 = 3 . . . . rearrange the second equation
The solution is (x, y) = (3, -1).
__
The slope of this equation is -5 [the x-coefficient]. I would start at +3 [the y-intercept] on the y axis and then drop down 5 and run over 1 .
[The slope is the ratio of rise to run. A slope of -5 means the "rise" is a drop of 5 for each "run" of 1 unit to the right.]
It will take to complete cases 4 days per 5 cases.
50 testers can complete 25 test cases in 10 days.
All testers are equally productive.
A project has 25 testers and 50 test cases.
How much time will they take to complete?
50 testers can complete 25 test cases in 10 days.
The number of cases completed per day is,
The number of cases completed per day is 2.
A project has 25 testers and 50 test cases.
The time will they take to complete is 2x.
= 2(2) = 4 days per 5 cases
Hence, they will take to complete cases 4 days per 5 cases.

Answer:
40 Days
Step-by-step explanation:
50 testers
25 test case
-> 10 days
(2 days per 5 cases)
25 testers
50 test cases
2x the effort of 50 testers.
(4 days per 5 cases)
-> 40 days
» Each y value is determined by
multiplying each x value by 3, so the
pattern is multiplicative
» Each y value is determined by adding
4 to each x value, so the pattern is
additive
» Each y-value is determined by adding
2 to each value, so the pattern is
additive
