Answer:

x > -2

Step-by-step explanation:

-2(3x+4) < -4+8 (evaluate right side)

-2(3x+4) < 4 (expand the parentheses on the left side using distributive property)

3x(-2) + 4(-2) < 4

-6x - 8 < 4 (add 8 to both sides)

-6x < 4 + 8

-6x < 12 (divide both sides by 6)

-x < (12/6)

-x < 2 (multiply both sides by -1; remember to flip the sign when multiplying both sides by a negative number)

x > -2

The function f(x) = 2x -3 is changed to f(x)+k. The new function f(x) can be represented by the graph below. What is the value o

OleMash [197]

As you can see in this picture we have a point on y- axis which is our y-intercept and f(x)
so first we should find what WAS the y-intercept before adding k
so we can say:
f(x) = 2(0) - 3 = -3
so it WAS -3 .... but in this picture is -7
so you have:
-3 + k = -7
k = -7 + 3 = -4
so k is equal to -4 :)))
i hope this is helpful
