Answer:
y-4 =-1(x+1) point slope form
y-2 = -1(x-1)
y = -x +3 slope intercept form
Step-by-step explanation:
We have 2 points, we can find the slope
m = (y2-y1)/(x2-x1)
= (2-4)/(1--1)
(2-4)/(1+1)
-2/2
=-1
The slope is -1
Then we can use point slope form to find an equation
y-y1 =m(x-x1)
y-4 = -1(x--1)
y-4 =-1(x+1) point slope form
Using the other point
y-2 = -1(x-1)
Distribute the -1
y-2 = -1x +1
Add 2 to each side
y-2+2 = -x+1+2
y = -x +3 slope intercept form
Answer:
C. 12 feet.
Step-by-step explanation:
The lamp post has a shadow that's twice as long as it'a actual height. The tree's shadow is 24 feet long, so it would be 24/2, which is 12 feet.
Answer:
13/84
Step-by-step explanation:
TanA = opposite/adjacent = 13/84
The first thing we must keep in mind is the following unit conversion:
We have then that for 35 gigabytes:
Part A:
For this case we make the following rule of three:
2000 bytes --------------> 1 page
35*10^9 bytes ----------> x
From here, we clear x:
Part B:
Then, the number of 500-page books is:
To make this easier, you want to do 5 1/2 into a decimal. 5.5, next divide to find her pace per minute. 12/ 5.5 =2.1818
Multiply that by 60, and your answer is 130
