Answer:

For the question on the right, I assume b is the exponential factor, or growth factor.

Step-by-step explanation:

Linear:

$Y=aX + b\\(X, Y) = (0, 15) => b = 15\\(X,Y) = (1, 12) => a = -3\\Y = -3X + 15$

You can find the equation by using two points and the equation for a line.

Exponential:

$Y = a^{bX+c}\\(X, Y) = (0, 81) => a^{c} = 81 => a^{c} = 3^{4} => a=3, c=4\\(X, Y) = (1, 27) => a^{b+c} = 27 => a^{b}a^{c} = 27 => a^{b} = \frac{27}{81} = \frac{1}{3} => b=-1\\Y = 3^{-X+4}$

Does the graph represent a function?

S_A_V [24]

The answer is not it is not because if you use the vertical line test it does not pass and if you plotted the coordinates then x would repeat multiple times

Hope this helps

Improper fraction for 5 9/13

ipn [44]

Answer: 87/13

So 6*13 = 78 78+9=87 and then you take the 87 and put it over the 13,

So, now you have your answer: 87/13

Jet001 [13]

Answer:

1. (4x-10)/2

4x/2 - 10/2

2x - 5

2. (1-50x)/-2

1/-2 -50x/-2

25x - 1/2

3. 5(x + 10)/25

(5x + 50)/25

5x/25 + 50/25

1/5 x + 2

4.(-0.2x + 5)/2

-0.2x/2 + 5/2

-0.1x + 2.5
