Answer:
wah
Step-by-step explanation:
As in step 2 the student added -2 only at one side of equation which is against the law of addition property of equality
so the correct option from above equation is
The student did not properly apply the addition property of equality to isolate x.
SO its B
hope it helps

Hello,
A=(-4,2)
B=(3,-5)
AB≡y-2=(x+4)(-7)/7==>y=-x-2
Slope of the perpendicular: 1
y-2=(x-1)1==>y=x+1 is the equation of the perpendicular.
Intersection: y=x+1 and y=-x-2 ==>(-3/2,-1/2)=Q
|PQ|²=(-1/2-2)²+(1+3/2)²=25/2
|PQ|=5√2/2≈3.5355339059....
P1=(0,233)=(x1,y1)→x1=0, y1=233
P2=(10,246)=(x2,y2)→x2=10, y2=246
Slope: m=(y2-y1)/(x2-x1)
m=(246-233)/(10-0)
m=13/10
Point-slope equation:
y-y1=m(x-x1)
y-233=(13/10)(x-0)
y-233=(13/10)x
y=(13/10)x+233
Answer: The equation is y=(13/10)x+233
Answer:
Option A
Step-by-step explanation:
Since at. 0.05 level of significance, the p value was great than 0.05 but less than 0.1, we will fail to reject the null and conclude that the sample data does not provide enough evidence that the average life of the batteries is greater than 75 weeks.
