Answer:

b = 23/2 or b = 11.5

Step-by-step explanation:

STEP 1: Simplify both sides of the equation.

1/2(4b - 6) = 20

(1/2)(4b) + (1/2)(- 6) = 20 (DISTRIBUTE)

2b + - 3 = 20

2b - 3 = 20

STEP 2: Add 3 to both sides.

2b - 3 + 3 = 20 + 3

2b = 23

STEP 3: Divide both sides by 2.

2b/2 = 23/2

b = 23/2

To solve you move the variables to the side and divide both sides by the factor number that doesnt have the variables your answer would be b=23/2 as a decimal is 11.5

Answer:

y < 2x-3

Step-by-step explanation:

First you graph the -3, and the slope is 2 so you go up 2 and over 1. Since y is less than 2x-3, you shade the right region.

Use a graphing calculator to graph the function and its parent function. Then describe the transformations, f(x)=(x+3)+1/4

nlexa [21]

Most of the graphing resources used shows that the graph is translated up by 3.25 (3 + 1/4). If you add the 3 and the 1/4, you get the equation of a line:

f(x) = x + 3.25,

which means that the graph of f(x)= x now has a y intercept of 3.25.

The graphs are below. The red line represents f(x) = x, and the green line represents (x+3)+1/4. Hope this helps!
