Answer:
9/1
Step-by-step explanation:
$27 for 3 hours. To find the slope, it always has to be over 1 hour because it's a unit rate. 27/3 would be 9. It makes sense too because $9 per 1 hour is the same as $27 for 3 hours.
Answer:
the slope is 9
Step-by-step explanation:
The slope is how much it cost per hour so that means if you do 27 divided by 3 then you get 9 cause 3 hours is 27 but one hour is 9
how you check if your right is by adding 9 up 3 times
9+9+9=27

y=-3, x = 5, y = 3
Answer:
see below for the graph
Step-by-step explanation:
The desired graph has two y-intercepts and one x-intercept. It is not the graph of a function.
Here's one way to get there.
__
Start with the parent function y = |x| and scale it down so that it has a y-intercept of -1 and x-intercepts at ±1.
Now, it is ...
f(x) = |x| -1
We want to scale this vertically by a factor of -5. this puts the y-intercept at +5 and leaves the x-intercepts at ±1.
Horizontally, we want to scale the function by an expansion factor of 3. The transformed function g(x) will be ...
g(x) = -5f(x/3) = -5(|x/3| -1) = -5/3|x| +5
This function has two x-intercepts at ±3 and one y-intercept at y=5. By swapping the x- and y-variables, we can get an equation for the graph you want:
x = -(5/3)|y| +5
______
Comment on this answer
Since there are no requirements on the graph other than it have the listed intercepts, you can draw it free-hand through the intercept points. It need not be describable by an equation.
Q(−5, −2), S(3, 4)
Q(5, −2), S(−3, 4)
Q(−5, 2), S(−3, 4)
Answer:
Step-by-step explanation:
When we reflect accrox x-axis, that means we have to change y-coordinates to their opposite, from positive to negative, or from negative to positive.
So, in this case, the given points are
If we reflect these points accros x-axis, they would be
Therefore, the right answer is the third choice.
