Let a number = n
n(7) = 48
isolate the n. Divide 7 from both sides
n(7)/7 = 48/7
n = 48/7
Divide
n = 6.857 is your answer
hope this helps
Answer:
The triangles are congruent.
Step-by-step explanation:
The dashes represent the same size of a side.
If one of the triangles were flipped, the dashes will be in the same place on each triangle causing them to be congruent.
Answer:
It is a function.
Step-by-step explanation:
You can test if a graph is a function if you draw a vertical line anywhere on the graph and you see it hits two points.
This is the table for the graph.
![\left[\begin{array}{ccc}x&y\\-3&0\\0&1\\3&2\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx%26y%5C%5C-3%260%5C%5C0%261%5C%5C3%262%5Cend%7Barray%7D%5Cright%5D)
Remember these rules:
- Each x value, or input, has its unique y value, or output
- If you draw a vertical line anywhere on the graph, it should only go through one point
We can check these two rules for this graph:
- Does each x value have its own, unique y value? Yes
- If you draw a vertical line anywhere on the graph, does it only go through one point? Yes, there are no overlaps
Keep in mind that two different x-values can have the same y value.
Figure 1:
It has two x values with the same y-values.
Figure 2 and 3:
The vertical line goes through two points. So the same x-value has two different y-values.

(-2x + 4y)(3x - 7y) = -6x^2 - 28y^2 + 12yx
Answer:
the 3rd one x+2=5
Step-by-step explanation:
Why?
because you are going from small # to a bigger # so you know you are adding
there is 2 there and it says that it = 5
