Answer: -3

Step-by-step explanation:

The slope of a line passing thorough two points (a,b) and (c,d) is given by :-

m=\dfrac{d-b}{c-a}

From the given description, we observe that the line is passing through (1,-1) and (-1,5).

Then , the slope of the graph passing through (1,-1) and (-1,5) will be :

m=\dfrac{5-(-1)}{-1-1}\\\\\Rightarrow\ m=\dfrac{5+1}{-2}\\\\\Rightarrow\ m=\dfrac{6}{-2}=-3

Hence, the slope of this graph= -3

Answer:

-3

Step-by-step explanation:

The slope is the ratio of the change in y-coordinates to the change in x-coordinates:

... (5 -(-1))/(-1-1) = 6/-2 = -3

A florist must make 5 identical
Sonbull [250]

Answer:

A. 40x + 10y + 10z = $160

B. 8 Roses, 2 lilies and 2 irises

C.

1. 20x + 5y + 5z = $80

2. 4x + y + z = $16

3. 8x + 2y + 2z = $32

Step-by-step explanation:

Cost for each flower = $160/5 = $32

So we have $32 for each bouquet consisting of 12 flowers each.

Roses = x = $2.50 each

lilies = y = $4 each

irises = z = $2 each

8x + 2y + 2z = $32

8($2.50) + 2($4) + 2($2) = $32

$20 + $8 + $4 = $32

$32 = $32

a. Maximum budget is $160

40x + 10y + 10z = $160

40($2.50) + 10($4) + 10($2) = $160

$100 + $40 + $20 = $160

$160 = $160

b. From above

8x + 2y + 2z = $32

8 Roses, 2 lilies and 2 irises

c. No. There are other solutions If total cost is not limited

1. 20x + 5y + 5z

20($2.50) + 5($4) + 5($2)

$50 + $20 + $10

= $80

2. 4x + y + z

4($2.50) + $4 + $2

$10 + $4 + $2

= $16

3. 8x + 2y + 2z

8($2.50) + 2($4) + 2($2)

$20 + $8 + $4

= $32

Valentin [98]
If there are 24 hours a day, he hangs out 8 hours a day since 24-8-8=16

All activities are eqyal to 8/24, which simplifies to 1/3.

1/3 as a percent is 33.33...%

He should include 33.33..% three times in his circle graph.

Help now now now!!!!!!!!!!!!!!
WARRIOR [948]
The answer is 2. Here's why:

First if all, anything to the power of 0 is 1.
So n^0=1.
You need to plug in 3 for m, so then 6(3)^-1.
3^-1=1/3.
6 × 1/3= 6/3=2
2×1=2.
