If you want to solve the system of equations it will be:
Step 1: solve the equation for y
y= -19+7 → y= -12
Step 2: substitute y into the equation
-2x+3x(-12)=-19
Step 3: solve the equation for x
x= -17/2
Step 5: the possible solution is the order pair (x,y)
Answer: (-17/2 , -12)
Answer:
B. 17%.
Step-by-step explanation:
The General Probability Addition Rule is
P(A∪B) = P(A) + P(B) − P(A∩B) where P(A∪B) = P(A) or P(B) and P(A∩B) = P(A) and P(B).
So applying this to our problem we have:
0.57 = 0.43 + 0.31 - P( household has a cat and a dog)
so the answer is 0.43 + 0.31 - 0.57
= 0.17 or 17%.
