Use slope formula to find the missing coordinate.<br><br> (r, 1) and (5, -7) Slope = 8/3
Lena [83]

Answer:

r=8

Step-by-step explanation:

The formula for slope is

m = (y2-y1)/ (x2-x1)

Substitute in what we know.

8/3 = (-7-1)/(5-r)

Simplify

8/3 = -8/(5-r)

We can use cross products to help us solve.

8 * (5-r) = 3 * (-8)

divide each side by 8

8/8 * (5-r) = 3 * (-8)/8

5-r = -3

Subtract 5 from each side

5-r-5 = -3-5

-r = -8

Multiply by -1

r = 8

the ratio of black bags to blue bags is 5 to 3. If there are a total of 185 black bags, then how many blue bags are there?
nlexa [21]

Answer:

There are 111 blue bags

Step-by-step explanation:

Let

x ----> the number of black bags

y ---> the number of blue bags

we know that

\frac{x}{y}=\frac{5}{3}

isolate the variable y

y=\frac{3}{5}x -----> equation A

x=185 ----> equation B

substitute equation B in equation A

y=\frac{3}{5}(185)

y=111

therefore

There are 111 blue bags
