Answer:
#1 is 28
Step-by-step explanation:
Set the perimeters equal, as 6x - 2 = 8x - 12, solve for x = 5, and plug in.
Answer:
18
Step-by-step explanation:
We know that line FH total length is 49. We also know that the length of line GH is 31.
To find FG, all we need to do is subtract 49-31 to find the length of FG.
Line FG total length is 18.
Answer:
b = -33/l
Step-by-step explanation:
-1lb + 7 = 40
-1lb = 33 (subtraction property of equality)
-1lb/l = 33/l (division property of equality)
-1b/-1 = -33/l (division property of equality)
b = -33/l (solved)
Standard form of line:
Ax + By = C
where A, B, and C are integers, and A is positive
slope-point form of a line:
y - y1 = m(x - x1)
where m is the slope and (x1, y1) is a point on the line. Replacing with m = 3 and point (2, 5):
y - 5 = 3(x - 2)
y - 5 = 3x - 3(2) distributing
y - 5 = 3x - 6
y - 5 - y = 3x - 6 - y subtracting y at both sides
- 5 = 3x - 6 - y
- 5 + 6 = 3x - 6 - y + 6 adding 6 at both sides
1 = 3x - y which has the standard form
