Jake and mike took a different number of tests. jake scored 85 points on each test. mike's total score was 15 less than jake's total score. the following expression shows mike's total score: 85x − 15 in the expression, what does the variable x represent? a. the total number of tests mike took b. the total number of tests jake took c. the sum of jake's and mike's total score d. the difference between jake's and mike's total score

We have been given that Jake scored 85 points on each test.

If we suppose that Jake took x test then total number of points scores by Jake is 85x.

Now, we have been given that Mike's total score was 15 less than Jake's total score.

Therefore, Mike's total score is given by

Therefore, the variable x represents the total number of tests Jake took.

B is the correct option.

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
