Answer: -10
Step-by-step explanation:
Simplifying
-3(y + 5) = 15
Reorder the terms:
-3(5 + y) = 15
(5 * -3 + y * -3) = 15
(-15 + -3y) = 15
Solving
-15 + -3y = 15
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + -3y = 15 + 15
Combine like terms: -15 + 15 = 0
0 + -3y = 15 + 15
-3y = 15 + 15
Combine like terms: 15 + 15 = 30
-3y = 30
Divide each side by '-3'.
y = -10
Simplifying
Answer:
y=(x+2)/4
Step-by-step explanation:
f(x) = 4x +2 is the original equation
x = 4y + 2 is the inverse but we have to solve for y
x+2=4y
4y=x+2
y=(x+2)/4
The correct answer is option 3: m≤-15
Step-by-step explanation:
The inequalities are solved by performing operations on both sides of inequality
Given inequality is:
when an inequality is multiplied by -1 the signs of numbers on both sides are changed while the inequality operator is also reversed.
Multiplying both sides by -1 will give us:
The correct answer is option 3: m≤-15
