I believe all you do is multiply both coordinates by 22.
( -88, 66)
Answer:
There would be 5.5 or 5 1/2 classes
Step-by-step explanation:
Turn fractions into decimals
Multiply each by 60
Then Divide
The only way that 2 lines don't intersect is when they are paralell
the only time 2 lines that are straight are paralell, is when the slopes are the same
find the slopes
slope=(y1-y2)/(x1-x2)
so the points of the line (0,-1) and (2,3) are
y1=-1
y2=3
x1=0
x2=2 so subsitute
(-1-3)/(0-2)=-4/-2=4/2=2
slope=2
the ohter one
points (-2,4) and (-3,3)
y1=4
y2=3
x1=-2
x2=-3
subsitute
(4-3)/(-2-(-3))=1/(-2+3)=1/1=1
slope=1
the slopes are different so they will intersect
Answer:
The answer to your question is: 10 units
Step-by-step explanation:
P (-3, -12)
1.- Find the center of the circle
x² + y² = 6x - 8y + 24
x² - 6x + ( )² + y² + 8y + ( )² = 24
x² - 6x + (3)² + y² + 8y + (4)² = 24 + 9 + 16
(x - 3)² + (y + 4)² = 49
Center (3, -4)
2.- Find the distance between the center and the point given
Formula
d = ![\sqrt{(x2- x1)^{2} + (y2 - y1)^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%28x2-%20x1%29%5E%7B2%7D%20%2B%20%28y2%20-%20y1%29%5E%7B2%7D%20%7D)
Substitution
d = ![\sqrt{(-3 - 3)^{2} + (-12 +4)^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%28-3%20-%203%29%5E%7B2%7D%20%2B%20%28-12%20%2B4%29%5E%7B2%7D%20%7D)
d = ![\sqrt{(-6)^{2} + (-8)^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%28-6%29%5E%7B2%7D%20%2B%20%28-8%29%5E%7B2%7D%20%7D)
d = ![\sqrt{36 + 64} }](https://tex.z-dn.net/?f=%5Csqrt%7B36%20%2B%2064%7D%20%7D)
d = ![\sqrt{100}](https://tex.z-dn.net/?f=%5Csqrt%7B100%7D)
d = 10 units
