d,
If you change the y-intercept but keep the slope the same, it just moves the line up or down. Since the lines would have the same slope (same rate of change), the two lines would be parallel.
Answer:
yes
Step-by-step explanation:
It is true
Inverse operation means the opposite and the opposite of subtract is add so your answer would be B. Add 6
Answer:
Step-by-step explanation:
Given that,
Slope of line is 8
m=8
And we are given two points where the line pass through
(x1,y1) = (9,v). ; x1=9, y1=v
(x2,y2)= (8,2). ; x2=8, y2=2
The slope of a line is given as
m=∆y/∆x
m=(y2-y1)/(x2-x1)
8=(2-v)/(8-9)
8=(2-v)/(-1)
Cross multiply
8×-1=2-v
-8=2-v
Subtract 2 from both sides
-8-2=2-v-2
-10=-v
Divide both sides by -1
-10/-1=-v/-1
Note, -÷-=+
10=v
Then v=10
Answer:
56 screws
Step-by-step explanation:
So, first we can find how many screws he needs.
So, if he uses 2 steps for 8 screws, and has 14 steps, that means he puts screws in 7 steps ( 14÷2)
then, if he uses 8 screws, each with 8 steps, we can do 8 times 7, which is 56 screws
