Answer:
Plug in the values for x
Step-by-step explanation:
plug in x values into the equation
for example, plug -2 into the equation. y= -2(-2). y=4
So on and so forth
Answer:
x = 14
JHK = 21
Step-by-step explanation:
The angles are vertical angles and vertical angles are equal
3x-21 = x+7
Subtract x from each side
3x-x -21 = x+7-x
2x-21 = 7
Add 21 to each side
2x-21+21 = 7+21
2x = 28
Divide by 2
2x/2 =28/2
x = 14
JHK = 3x-21 = 3(14) -21 = 42-21 = 21
Answer:
x > 12, so the answer is the last one or D
Step-by-step explanation:
2/3x − 5 > 3
Step 1: Add 5 to both sides.
2/3x − 5 + 5 > 3 + 5
2/3x > 8
Step 2: Multiply both sides by 3/2.
2/3x * (3/2) > 8 * (3/2)
x > 12
> = open circle
< = open circle
≤ = closed circle
≥ = closed circle
