Eduardo solved the following inequality, and his work is shown below: −5(x + 4) ≥ 4x − 38 −5x − 20 ≥ 4x − 38 −9x − 20 ≥ −38 −9x ≥ −18 x ≥ 2 What mistake did Eduardo make in solving the inequality? A. When dividing by −9, he did not change the direction of the sign. B. He subtracted 4x from both sides when he should have added. C. He added 20 to both sides when he should have subtracted. D. He did not make a mistake.

answer: 48

just remember to use pemdas:

parentheses

expressions

multiplication

division

addition

subtraction

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
