Brainliest for best answer
Naily [24]

Answer:

Step-by-step explanation:

________

Good evening ,

_______________

-4x+3y=-12

-2x+3y=-18

This system is the same as

y = (4/3)x - 4

y = (2/3)x - 6

We note that the two coefficients 4/3 and 2/3 are positives

So the right answer is C (graph 2).

Can you guys help me​
Fudgin [204]

Answer:

The answer is 76.

Step-by-step explanation:

≅ means to be equal to.

☆Angle DGE ≅ EGF.

Therefore, 3x + 8 = 5x - 12

☆Let's solve that equation.

3x  + 8 = 5x - 12 \\  \frac{ - 5x \:  \:  \:  \:  \:  \:  \:   =  - 5x  \:  \:   \:  \:   \: \:  \:  \: }{ - 2x + 8 =  - 12}  \\  \frac{  \:  \:  \:  \:  \:  \:  \:  \: - 8  =  - 8}{  \frac{ - 2x}{ - 2}  =  \frac{ - 20}{ - 2} }   \\ x = 10

We found the value of x which is 10.

☆Let's Now plug in.

DGE \\ 3x + 8 \\ 3(10) + 8 \\ 30 + 8 \\ 38

and the other:

EGF \\ 5x - 12 \\ 5(10) - 12 \\ 50 - 12 \\ 38

☆They asked for what the angle of DGF measured. So we would have to add both sides

38 + 38 = 76

☆The answer is 76

Please help which should I choose
Aleksandr [31]
<h3>Answer: Choice A. Graph (1)</h3>

Reasoning:

If it is at all possible to draw a single vertical line through more than one point on the curve, then the graph is not a function. With graphs (2), (3) and (4), we can draw a vertical line through more than one point on those curves, so they aren't functions. Graph (1) is the only thing left. This graph is a function because it is not possible to draw a single vertical line through more than one point. It passes the vertical line test. Any input (x) leads to exactly one and only one y output.

Nice work on getting the correct answer when you chose "graph (1)".
