Answer:
-1
Step-by-step explanation:
it goes over -6 and up 6. so as a fraction it would be -6/6. but thats also equal to -1, so that is what you would put as your answer
(x₁,y₁) = (2,-3)
(x₂,y₂) = (2,9)
To determine the slope using two points lie on the line, we could use the following formula
m =

plug in the numbers
m =

m =

m =

m = undefined
The slope is undefined, the line is vertical
It had taken a while for me to understand the problem. From what I understood, the given pairs of points are tabulated below:
x f(x) -7 -11
-1 1
3 9
4 11
7 17
Then, the choices are equations in terms of x. The correct equation should yield the pairs tabulated above when the x-values are substituted into the equation. So, the solution is basically just substituting x to each of those equations, then you get the corresponding y values. Check which of those question has pairs similar to the given. I suggest that you tabulate the numbers so that it would be easier for you. For me, I used MS Excel as shown in the picture. Th x-values are in the first column gathered from the given. I applied the equations to get the f(x) values. As you can see, the pairs matched with the third column. Therefore, the answer is:
f(x) = 2x+3.
Answer:
mZB= 74
Step-by-step explanation:
ZB+ZA=180
3X-23+2X-12=180
5X-35=180
5X=180+35
5X=215 (then divide both sides by 5 to x be left alone.)
X=43....so ZB=2(43)-12
=86-12=74
Answer:
Exponential function: a*b^x
if B is less than 1, it is a decay function
if B is more than 1, then it is a growth function
if B is 0, then the function neither decreases nor increases
Example 1: 100*0.14^x
The y-intercept is decreasing by 86%
Example 2: 3000*1.14^x
The y-intercept is increasing by 14%
Example 3: 400*0
The y-intercept is neither decreasing nor increasing
Going back to the function, <u>a</u> is the y-intercept, and <u>b</u> is the rate
<u>I hope this will help you, I just started to learn about exponential functions..</u>
