Does (8, 1) make the inequality y<x+9 true?

1. The correct answer is letter (C) There is no solution since 4 = 5 is a false statement.

2. The equation that has solution is:
6x - (3x + 8) = 16x

6x - 3x - 8 = 16x

3x - 8 = 16x

-13x = 8

x = -8/13

3. The coordinate grids above shows equations y = 3x - 2 and 2x - y = 4. The correct answer is graph letter (A)

4. Select ALL of the functions.

The functions are letter (A) and letter (D).

5. Write the difference in the rates of change for these two functions

The equation in the table is

m = (Y1-Y2) / (X1-X2)

m = (4-12) / (0-2)

m = -8 / -2

m = 4

y = mx+b

4 = 4(0) + b

b = -4

So the equation of the table is y = 4x - 4.

The second equation is y = 7x + 4.

(0 , 4)

(2 , 18)

(4 , 32)

(6 , 46)

The difference rate is (0, 6, 12, 18) is 6n.

6. The function is linear.

7. The function is nonlinear.

8. The function is linear.

9. The function is nonlinear.

10. The correct answer is letter (C).

11. The correct answer is letter D. Linear function with positive slope
