8 0

When x = -1, f(x)=3(-1) +2 = -1
when x = 0, f(x)=3(0) +2 = 2
when x = 2, f(x)=3(2) +2 = 8

range: {-1, 2, 8|

Allison, Brianna, and Celeste went on a hike. Allison brought 9 homemade

poizon [28]

Answer:

Allison = $0.27

Brianna = $1.89

Step-by-step explanation:

The total cookies that the three girls have are:

Allison's cookies + Brianna's Cookies

= 9+15

=24

There is a total of 24 cookies which has to be divided between the 3.

Each girl gets 24/3 = 8 cookies.

Since Celeste had no cookies she will have to pay for the 8 cookies.

Allison had 9, she will give one to Celeste

Brianna had 15 out of which she will use 8 for her self and 7 will be given to Celeste.

Celeste is paying 2.16 for 8 cookies.

Price of one cookie = 2.16/8

=$0.27

So, amount that will be given to Allison = 0.27 * 1 = $0.27

Amount that will be given to Brianna = 0.27 * 7 = $1.89

1. Solve and verify each of the following systems of linear equations.

kakasveta [241]

5x - 2y = -6 ⇒ 10x - 4y = -12
2x - 1y = 1 ⇒ 10x - 5y = 5
 y = -17
 5x - 2(-17) = -6
 5x + 34 = -6
 - 34 - 34
 5x = -40
 5 5
 x = -8
 (x, y) = (-8, -17)

2x + 3y = 432 ⇒ 10x + 15y = 2160
5x + 2y = 16 ⇒ 10x + 4y = 32
 11y = 2128
 11 11
 y = 193.4545455
 2x + 3(193.4545455) = 432
 2x + 580.3636364 = 432
 - 580.3636364 - 580.3636364
 2x = -148.3636364
 2 2
 x = -74.1818182
 (x, y) = (-74.1818184, 193.4545455)

The first T-shirt you buy costs $7, and every additional shirt costs only $5. Let f(n) be the total cost of n shirts. F is a seq

Zina [86]

Answer:

f(n) = 2 + 5n. This is an arithmetic sequence.

Step-by-step explanation:

f(1) = 7

f(2) = 7 + 5

f(3) = 7 + 5 + 5 = 7 +10

f(4) = 7 + 5 + 5 + 5 = 7 + 15

In general,

f(n) = 7 + 5(n -1 )

= 7 + 5n - 5

= 2 + 5n

We have the sequence 7, 12, 17, 22, 27 …

This is an arithmetic sequence, because it is a sequence of numbers in which the common difference between consecutive terms is 5.
