Answer:
27 dollars a week
Step-by-step explanation:
Well there’s 72 weeks in 18 months so 2,000 divided 72 equals 27.

87. The domain of added functions includes the restrictions of both. So the range of the added function in this question is [-4, 3]
88. When finding the domain of a divided function we do the same as adding, but with an extra rule: g can't equal zero. So for this question the domain is (-4, 3)
89. To graph f + g you add the y-values for each x-value. I added a picture to help explain this one!
Answer: (B)
Explanation: If you are unsure about where to start, you could always plot some numbers down until you see a general pattern.
But a more intuitive way is to determine what happens during each transformation.
A regular y = |x| will have its vertex at the origin, because nothing is changed for a y = |x| graph. We have a ray that is reflected at the origin about the y-axis.
Now, let's explore the different transformations for an absolute value graph by taking a y = |x + h| graph.
What happens to the graph?
Well, we have shifted the graph -h units, just like a normal trigonometric, linear, or even parabolic graph. That is, we have shifted the graph h units to its negative side (to the left).
What about the y = |x| + h graph?
Well, like a parabola, we shift it h units upwards, and if h is negative, we shift it h units downwards.
So, if you understand what each transformation does, then you would be able to identify the changes in the shape's location.
Answer:
13. (1) x + 8x = 32
14. $337.5
Step-by-step explanation:
14. $270 x 0.25 = 67.5
270 + 67.5 = 337.5
I am sorry. I only got these-
Answer:
value of blue dot is -6
Step-by-step explanation:
-6 is visible if you go 3 units to the left of -3. -3 - 3 = -6.
