1 answer:
Answer:
B. (8, -54)
Step-by-step explanation:
y = -7x + 2
Check to see if the point makes the equation true
A. (1,2) 2 = -7(1)+2 = -7+2 = 5 False
B. (8, -54) -54 = -7(8)+2 = -56+2 = -54 True
C. (5, -35) -35 = -7(5) +2 = -35+2 = -33 False
D. (1, -7) -7 =-7(1)+2 = --7+2 = -5 False

1. Find a common denominator
1/4 2/3 both have 12 in common
1/4=3/12
2/3=8/12
2. Add both
3/12+8/12=11/12
3. Subtract
12/12-11/12=1/12
1/12 of the students have neither brown nor blue eyes

Answer:
D) -21.5
Step-by-step explanation:
Your answer would be
B. the estimated average change in y per unit change in x
Answer:
x= 1
Step-by-step explanation:
y= -2 + 1
3x - 2y = 5
substituting method:
substituting y= -2+1 in equ. 3x-2y=5
=> 3x - 2(-2 + 1) = 5
=> 3x +4 -2 = 5
=> 3x + 2 = 5
=> 3x = 5 -2
=> 3x = 3
=> x = 3/3
=> x = 1
