5x – 1 = 3x – 15
Subtraction Property of Equality (Subtract 3x from both sides)
2x - 1 = -15
Addition Property of Equality (Add 1 to both sides)
2x = - 14
Division Property of Equality (Divide both sides by 2)
x = -7
Answer:
what grade is this?
Step-by-step explanation:
Answer:
It is greater because when you divide decimals you move the decimal which would automatically make the product less than the quotient.
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
Pytago: a^2 + b^2 = c^2
x =
= 15
Answer:
y-6 = -7x + 21
Step-by-step explanation:
Find the slope
(-8 - 6)/(5-3)
-14/2 = -7
Now find the formula
y-6=-7(x - 3)
y-6 = -7x + 21
Another way to write it is
y= -7x + 27
