Answer:

B

Step-by-step explanation:

Plug x as 4 and y as 2.

2 = 4 - 2

2 = 2 <em>True</em>

2 = 3(4) + 4

2 = 12 + 4

2 = 16 <em>False</em>

Answer:

No.

Step-by-step explanation:

Substitute 4 (as x) and 2 (as y) into the 2 equations to see if they fit.

y = x - 2

2 = 4 - 2

2 = 2

The first equation is true for (4,2).

Now try the 2nd one.

y = 3x + 4

2 = 3(4) + 4

2 ≠ 16

So the 2nd equation is not true for (4,2).

Either one not true makes the solution incorrect.

Consider functions f and g defined by the graph and the table.<br><br> Please help me ASAP
Fed [463]

Answer:

Step-by-step explanation:

Given are two functions represented one by graph and another by table

We can check the given statement one by one

1) f(2)=18 : f(0) =15

Average rate of change = \frac{18-15}{2-0} =1.5

For g(x) avg rate of change

=\frac{g(2)-g(0)}{2-0} \\=4

Hence g has a higher average rate of change than f.

True

2)f is linear and eventually exceeds g (f(0)>g(0) . True

3) True because y intercept is 10 for f while 8 for g

4) True because f(3) <g(3)

5) False both cannot be linear

Whatis the value of y?​
Romashka [77]
Answer is A, y = 65

The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.

***Question is on the picture ​
RUDIKE [14]

Answer:

M(4, -3)

Step-by-step explanation:

Reflecting over the x-axis is simple:

If the x is positive, the reflection would be negative and vice versa.

In this case, the <em>y </em>isn't affected since it's only reflecting over the x-axis.

So, M is at the coordinates (4, -3)
