Jada is solving the equation shown below. -1/2 (x+4) = 6 which is a possible first step to begin to simplify the equation? check all that apply. divide both sides of the equation by –2. subtract 4 from both sides of the equation. multiply both sides of the equation by –2. distribute –2 over (x+4). distribute -1/2 over (x=4). multiply both sides of the equation by -1/2.

Multiply both sides of the equation by -2

Distribute -1/2 over (x+4)

Step-by-step explanation:

we have

Method 1

Multiply both sides of the equation by -2 ------> Step 1

Subtract 4 from both sides of the equation

Method 2

Distribute -1/2 over (x+4)-------> Step 1

Multiply both sides of the equation by -2

Subtract 4 from both sides of the equation

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
