Answer:
x= -2 and x = 6
Step-by-step explanation:
The solutions are where the two graphs intersect
x=6, y= 10 is one point
x=-2 and y = -6 is the other point
-10x + 1 + 7x =37
-10x + 7x = 37 - 1
-2x = 36
X = 36 / -2
X = -18
Answer is x = -18
I think this is the answer

Step-by-step explanation:
Let x be the miles Kenyon ran on tuesday
Let y be the miles Kenyon ran on thursday
Given,
Mon + Tues + Wed + Thu = 8mi
also given,
Now we have x + y = 5.2 as equation 1 and -x + y = 0.4 as equation 2
Using equation 1,
Substitute this equation into equation 2.
Substitute y = 2.8 into equation 1.
Therefore Kenyon ran 2.4 miles on tuesday, and ran 2.8 miles on thursday.
5 Girls + 3 Boys =8 (sample size)
Probability of choosing 1 boy P(1 B) = 3/8
Probability of NOT CHOOSING ANY BOY = 1-3/8 =5/8
Now apply the binomial probability to choose 3 Boys:
8C3(3/8)³(5/8)⁵ ==>P(All boys) = 0.28
Answer:
The answer is Answer choice A
Step-by-step explanation:
Because 4-1=3
