Let x be the fifth number
⇔
⇔ 23.3 + x = 34
⇔ x = 10.7
Answer:
A and C
Step-by-step explanation:
It can not be D, since that will mean that <em>the line is perfectly horizontal</em>, with 0 as its slope.
It can be C, since the <em>equation's slope is positive and has a negative y-intercept</em>, like the graph.
Changing around A gives us y = 2x - 3. That has a <em>positive slope and a negative y-intercept</em>, like the graph. So, A is a possibility.
Changing around B gives us y = ²/₃x + 3. This has a positive slope, <em>but also a positive y-intercept</em>, so B can not be the answer.
Answer:
scale factor is 3, k=3
Step-by-step explanation:
everything is being multiplied by 3
Answer:
3+(k+1)1.5= 3
Step-by-step explanation: you do 1.5 * k and 1 and get 1.5k + 1.5
then you go 3 +1.5k+1.5=?
1.5k+4.5=?
-1.5k -1.5k
4.5=-1.5
_ . _
-1.5 . -1.5
k=3
Since 2 cases = $48
÷ 48 by 2 to get the cost of one case of paper
48÷2=$24 per case
and each case has 12 pack of paper
so $24 for 12 packs of paper
180÷12=15, which gives you the number of case you need
15 cases × $24= $360 for 180 packs
