Which of the following equations has an infinite number of solutions? (1 point)

3x 3 = 4x

2y + 4 y = 16

7x + 5 = 4x + 5 + 3x

6y 2 = 2(y 1)

4.

Graph the inequality: x ≤ 2 (1 point)

number line

5.

4x + 2 = x + 8. (1 point)

x = 4

x = 3

x = 2

x = 1

Solve the inequality.

6.

q 12 ≥ 13 (1 point)

q ≥ 1

q ≥ 1

q ≥ 25

q ≥ 25

7.

12p < 96 (1 point)

p < 8

p < 108

p < 84

p < 8

8.

g/5 < 18 (1 point)

g < 23

g > 90

g > 90

g < 90

9.

Write the inequality and solve for the following problem:

The result of 6 subtracted from a number n is at least 2. (1 point)

n 2 > 6; n > 8

n 6 ≥ 2; n ≥ 8

n + 6 ≥ 2; n ≤ 4

n + 6 ≥ 2; n ≥ 4

i dont get this at all :T

1. 5h-9 = -16*6h.

5h-6h = -16+9

-h = -7

Multiply both sides by -1:

h = 7.

2. Same as #1.

3. 7x+5 = 4x+5+3x.

7x-3x-4x = 5-5

0 = 0 is a true statement.

But all values of x will satisfy the given Eq. Try a few.

4. x =< -2.

Graph x = -2(A ver. line).

(x,y).

(-2,2)

(-2,0)

(-2,-2)

5. Same as #1.

6. q-12 >= -13

q >= -13+12

q >= -1.

7. Divide both sides by 12.

8. Multiply both sides by -5 and reverse the sign.

9. n-6 >= 2.

n => 8.
