Answer:
it is 45
Step-by-step explanation:
677
Answer:
B, C, D, & E
Step-by-step explanation:
All lines intersect the x axis and y axis so we know B and D are correct. All graphs are in the xy plane unless i (
) is involved, or C. It crosses the center (origin) of the entire plane so it crosses the origin, or E.
2(3y+10)=38
6y+20=38
6y=18
y=3
You use the distance distance formula d √︎(x₂-x₁)+(y₂-y₁) on this as well as y=mx+b.
With mx+b you find your second set of coordinates. With the distance formula you get your square root.
So y=-3x+10 well send you 10 up the y intercept the, neg 3 down, and positive one across the x axis.
This gives you your second set of coordinates (1,7) to go with your first set.
You apply both sets of coordinates to the distance formula. d √︎(x₂-x₁)+(y₂-y₁)
You get √︎(1-(-6))+(7-8)
Then √︎7-1
Finally √︎6
And √︎6 is between 2*2 and 3*3
Rough guess, the Sq root of 6 is 2.449 or rounded to the hundredth 2.45
