Answer:
60 feet
Step-by-step explanation:
Setting the proportion up:
x/25=24/10
Cross Multiply.
10x=24*25
10x=600
Divide both sides by 10.
x=60
Part A
The first thing we must do in this case is to hide the slopes of each line.
line m:
m = (- 4-3) / (0 - (- 4))
m = -7 / 4
Line n:
n = (- 2-2) / (3-1)
n = -4 / 2
n = -2
Answer:
Lines m and n are not parallel because their slopes are different.
Part B:
We look for the slope of the K line:
k = (1 - (- 3)) / (4 - (- 3))
k = 4/7
We observe that it is true that:
k = -1 / m
Answer:
The lines are perpendicular.
Answer:
Step-by-step explanation:
first, do 30-2 to get 28. 7-28 is -21. -21/7 is -3
The slope-intercept form: y = mx + b
m - slope
b - y-intercept
We have y = 4x + 3
m = 4 - slope
3 - y-intercept
4 units up and 1 unit right
Answer:
459/99
Step-by-step explanation:
0.6363... is equal to 63/99.
We want to add 4.
4 = 396/99
396/99 + 63/99 = 459/99
We can double check with a calc.
