A- It's LINEAR: every 2 other weeks, her savings increase by a CONSTANT amount of $12 (per 2 weeks) or $6/week

B- After the 2 first week she had $20 less the $12 (baby sitting for 2 weeks) =$8. This is the amount she saved prior to babysitting , then each week she added $6 (or $12 in 2 weeks)
If Y is the total amount of saving after a period of time T  & $6 is the rate per week & she started with $8, then the equation becomes Y= 6 T +8, where T is the number of weeks

C- the slope is the coefficient of T that means 6
As for Y intercept or where the function intercepts the Y axis it happens for T=0 & in this case Y intercept = 8
Hope it's clear

I’m sort of confused on how to state and find the domain and range of this graph
Yuliya22 [10]

    You have a special type of function, so you have to express the domain and range of each interval. Every aspect of this graph is closed, so you will only use brackets when writing your answers. Hence, you get [30,5] for the first interval, since there is a horizontal distance of 30 and a vertical distance of 5. You repeat the same process for each interval.

If a translation maps point (3, 2) to (5,3); or T:(3, 2) - (5,3), indicate the image for (2,4)
Zinaida [17]

Answer:

A

Step-by-step explanation:

Note that for (3, 2) → (5, 3)

The x- coordinate of the image is 2 more (+ 2) than the original and the y- coordinate of the image is 1 more (+ 1) than the original, that is

(x, y ) → (x + 2, y + 1 ) ← rule to obtain image, hence

(2, 4 ) → (2 + 2, 4 + 1 ) → (4, 5 ) → A

Joe went shopping for holiday gifts for her family. She has a budget of $150. She has 15 people to purchase a gift for, but also
Vitek1552 [10]
$150 (budget) - $30 (spend on herself) = $120 (left)

120 / 15 = $8

(150 - 30) divided by 15 = $8

Only $8 maximum can be spent on each family member
