Answer:

y = 4

Step-by-step explanation:

21 = 3(y + 3), Distribute

21 = 3y + 9, Subtract 9 on both sides

12 = 3y, Divide 3 on both sides

4 = y

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

Stells [14]

Answer: $\dfrac14$

Step-by-step explanation:

Given: The factory produces equal quantities of four flavors cherry lemon orange and strawberry.

Let orange candy= cherry = lemon = strawberry = x

Total candies = x + x + x + x= 4x

The probability that a randomly selected candy is orange = $\dfrac{x}{4x}=\dfrac14$

Hence, the probability that a randomly selected candy is orange = $\dfrac14$
