Answer:
D
Step-by-step explanation:
4/4 = 1
Answer:
y = -x + 10
Step-by-step explanation:
Slope Formula:
Slope-Intercept Form: y = mx + b
Step 1: Find slope <em>m</em>
m = (11 - 9)/(-1 - 1)
m = 2/-2
m = -1
y = -x + b
Step 2: Find y-intercept <em>b</em>
9 = -(1) + b
9 = -1 + b
b = 10
Step 3: Rewrite linear equation
y = -x + 10
Answer:
x = 17
Step-by-step explanation:
Given equation:
(6x + 3) + 75 = 180
Subtract 75 from both sides:
⇒ (6x + 3) + 75 - 75 = 180 - 75
⇒ 6x + 3 = 105
Subtract 3 from both sides:
⇒ 6x + 3 - 3 = 105 - 3
⇒ 6x = 102
Divide both sides by 6:
⇒ 6x ÷ 6 = 102 ÷ 6
⇒ x = 17
Answer:
y = 0
Step-by-step explanation:
Plug in 28 for x. Solve for the equation:
x + 3y = 28
(28) + 3y = 28
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 28 from both sides:
28 (-28) + 3y = 28 (-28)
3y = 0
Isolate the variable, y. Divide 3 from both sides:
(3y)/3 = (0)/3
y = 0
y = 0 is your answer.
