Suppose you have $20 to spend on party decorations. Balloons are $0.05 each, streamers are $0.25 each, and noisemakers are $0.40
sergejj [24]

[C] 0.05b + 0.25s + 0.4n = 20

b = balloons

s = streamers

n = noisemaker

Since they already give us the price of each item we just need to add a variable at the end of each one since we don't know how many of each item is bought. Adding the costs of all the party supplies should not go over $20. We can automatically eliminate B and D. We can also eliminate A because the prices of each item are incorrect. Therefore, C is the correct answer.

Best of Luck!

What is the answer to this problem<br> 8x-2=-9+7×
Ksenya-84 [330]
8x−2=−9+7x

Simplify:

8x−2=−9+7x

8x+−2=−9+7x

8x−2=7x−9

Subtract 7x from both sides.

8x−2−7x=7x−9−7x

x−2=−9

 Add 2 to both sides.

x−2+2=−9+2

x=−7

Domain and range of (4,-4),(2,-3),(-5,1),(4,-1)
aniked [119]

(x; y)


The domain is x.

The range is y.


Therefore

(4; -4) → x = 4; y = -4

(2;-3) → x = 2; y = -3

(-5; 1) → x = -5; y = 1

if is (-4; -1) not (4; -1) then

(-4; -1) → x = -4; y = -1


The DOMAIN = {-5; -4; 2; 4}

The RANGE = {-4; -3; -1; 1}


If is (4; -4) and (4; -1) then it is not a function.
