Are you sure you cancel out as seen on your paper? Because I would have said 2 4/7 was answer which is not the same as answer when you canceled out
Hi there!
The line is in slope-intercept form. This is y=mx+b, where b is the y intercept. Thus, because it is in this form, we can see that the y intercept is 3.
Now, for the x intercept. The x intercept is at y=0. Thus, we can just set y equal to 0 and solve for x.
0=-7x+3
-3=-7x
x=3/7
Thus, the x intercept is 3/7.
Our two answers are - x intercept = 3/7, y intercept = 3
Hope this helps!

Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
5 ( x - 2) + 4 ( 3 + x) = 20
Distribute
5x -10 +12 +4x = 20
Combine like terms
9x +2 = 20
Subtract 2 from each side
9x+2-2 = 20-2
9x = 18
Divide each side by 9
9x/9 = 18/9
x = 2
Answer:
1 : 1740
Step-by-step explanation:
The piece paper has 8 1/2" x 11", we have must find the appropriate dimensions on a scale such that the drawing of the Empire State is contained within the measures of the piece of paper. Leaving a margin of 1/2 "on both sides we have 10" high by 7 1/2" wide.
we choose the highest side of the piece of paper (11 "including margin 10") to cover the height and width (8 1/2 "including margin 7 1/2") for the base
.
1450 ft ≅ 10"(inch) then:
400 ft ≅ x "(inch); x=400ft*10"/1450ft ⇒ x=2.75", also
the scale is:
if 1450 ft ≅ 17400" ⇒ 17400" in the reality are 10" in the piece of paper, so the relation is 1 : 1740, is to say, 1" in the piece of paper is 1740" in the reality
Note: but wish to leave room, the scale can be 1 to more than 1740
