Answer:

Step-by-step explanation:

No. of white bands = 15% of 360 = (15/100)*360= 54

No.of red bands = 360 - 54 = 306

No. bands remaining = 360 - 140 = 220

No. of remaining white bands = 20% of 220= (20/100)*220 = 44

No. of remaining red bands = 220 - 44 = 176

No. of red band used = No.of red bands - No of remaining bands

= 306 - 176 = 130

What are the slope between (-5,-2) and (8,13)

Cerrena [4.2K]

Answer:

The slope:

$m = \frac{15}{13}$

Step-by-step explanation:

-To determine the slope of the following points shown, you need this formula:

$m = \frac{y_{2} - y{1}}{x_{2} - x_{1}}$

( $m$ represents the slope, $(x_{1}, y_{1})$ represents the first coordinate and $(x_{2},y_{2})$ represents the second coordinate)

-Apply the following points to the formula:

$m = \frac{13 + 2}{8 + 5}$

Then, solve:

$m = \frac{13 + 2}{8 + 5}$

$m = \frac{15}{13}$

So, the slope is $\frac{15}{13}$ .

E = = 5e + 3f = -36 -e + 2f = 2 f = 1

Ann [662]

Answer:

e = -6

f = -2

Step-by-step explanation:

I used the elimination method and multiplied the second equation by 5 to get:

-5e + 10f = 10. Added this to:

+ 5e + 3f = -36

13f = -26

f = -2

now find e: -e - 4 = 2

-e = 6

e = -6
