Identify the variation as direct, inverse, joint or combined. y = 7x

Direct variation

Step-by-step explanation:

Hi, to answer the question we haveto analyze the information given.

The expression of y =7x is a direct variation, because if the value of one variable changes, the other variable´s value changes as well.

for example:

if x = 1 , y = 7.

y= 7(1)=7

if x =2 , y= 14.

y = 7(2 ) =14

Feel free to ask for more if it´s necessary or if you did not understand something.

step-by-step explanation:

it's 15

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
