Answer:
-1.29
Step-by-step explanation:
y2-y1÷x2-x1
-13-59÷-35--21
-72÷56
-1.29
(3x+12)-5x=22
-15x^2-60x=22
-15x^2-60x-22=0
x=-b/2a
x=60/-30
x=-2
Answer:
the answer is step 3 because the circle on the number line is open.
pls make mine as the Brainliest answer that would really help
Answer:
Yes, each x-value has a unique y-value.
Step-by-step explanation:
This is a function because each x-value has its own y-value. If this is not the case then it is not a function, because then, two points with the same x-value and different y-values would fail the VLT.
Your graph does not have overlaps and each x-value has a unique y-value
VLT
The vertical line test (VLT) is a <u>simple method that mathematicians made because</u><u> they were lazy</u><u> to make a table of values and find duplicates. </u>
<u />
- Passing the VLT means that if you drew a vertical line anywhere on the graph, it would only go through one point.
- Failing the VLT would mean that the vertical line
A quick way to check if it is a function is by looking for duplicates of x-values and check that the duplicates have the same y-value.

Hello!
You can substitute y into the other equation
7 = -3x - 2
Add 2 to both sides
9 = -3x
Divide both sides by -3
-3 = x
The answer is -3
Hope this helps!
