Answer:
12+-8=4
Step-by-step explanation:
<em>this would be that same as 12-8=4, just keep the numbers but flip the negative into a positive number then change the equation into a subtraction problem if this confuses you.</em>
Answer:
According the the Property of Equality (POE), if a=b and b=c, then a=c.
If -8y + 8 = x and x = -2y + 2, substitute so that it becomes -8y + 8 = -2y + 2.
Solve from there:
Move the y variables to their own side.
-8y + 2y = 2-8
-6y = -6
y = -6
Then plug the y into either equation to find x.
x = -2y + 2
x = -2(-6) + 2
x = 12 + 2
x = 14
Answer:
This is a function because each x value has a different y value. If one of x values would of had two different y values then it would of not have been a function
Step-by-step explanation:
Answer:
x=7
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
x+30−4x=4x+9−4x
−3x+30=9
Step 2: Subtract 30 from both sides.
−3x+30−30=9−30
−3x=−21
Step 3: Divide both sides by -3.
−3x
−3
=
−21
−3
<u><em>The sides of a rhombus are all congruent (the same length.)</em></u>
