The total ball in the bag is 4 + 2 = 6 balls. Their are 4 red balls and 2 blue balls.

If they are drawn singly the probability that 2 blue balls are counted can be expressed as follows

$p(b)=\frac{2}{6}+\frac{2}{6}=\frac{4}{6}=\frac{2}{3}$

Solve the system of equations. 8x – 3y = 1 –2x + 3y = 11 A. (–1, –3) B. (–1, 3) C. (2, 5) D. (5, 2)

Makovka662 [10]

Answer:

C. (2, 5)

Step-by-step explanation:

Looking at the answer choices, you can see that solving for y will tell you which choice is correct. We can eliminate x from the equations by adding 4 times the second equation to the first:

(8x -3y) +4(-2x +3y) = (1) +4(11) . . . . . adding the equations to eliminate x

9y = 45 . . . simplified; next we divide by 9

y = 5 . . . . . matches choice C

Check

8(2) -3(5) = 16 -15 = 1

-2(2) +3(5) = -4 +15 = 11 . . . . the answer checks OK in both equations

Answer:

m = undef

General Formulas and Concepts:

Order of Operations: BPEMDAS
Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (3, 2)

Point (3, -2)

Step 2: Find slope m

Substitute: $m=\frac{-2-2}{3-3}$
Subtract: $m=\frac{-4}{0}$
Simplify: m = undef
