Solve the inequalities (i) 5 ≤ 2x − 4 ≤ 8 (ii) −10 < 4 −3y/− 5 ≤ 4

Step-by-step explanation:

(i) 5 ≤ 2x − 4 ≤ 8 add 4 to all three expressions

9 ≤ 2x ≤ 12 divide by 2

9/2 ≤ x ≤ 6

(ii) −10 < (4 −3y)/− 5 ≤ 4 multiply all sides by -5

-20 ≤ 4 - 3y < 50 subtract 4

-24 ≤ -3y < 46 divide with -3

-46/3 < y ≤ 8

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
