Answer:
9) -25/21
11) 14
Step-by-step explanation:
In each case, subtract the y-coordinates. Subtract the x-coordinates in the same order. Divide the difference in y by the difference in x.
9)
y-coordinates: -10 - 15 = -25
x-coordinates = 6 - (-15) = 21
slope = (difference in y)/(difference in x) = -25/21
11)
y-coordinates: -20 - 8 = -28
x-coordinates = 3 - 5 = -2
slope = (difference in y)/(difference in x) = -28/(-2) = 14
Rst is a right triangle rs=12 rt=20 st=15 what is sin r
Answer:
3/4 (0.75)
Step-by-step explanation:
sin r = 15/20 = 3/4 (0.75)
What is this answer?
What is the value of the expression
-1s/20r if r= -1/4 and s= 4/5?
Simplify your answer.
Answer:
[tex]\frac{4}{25}[/tex]
Step-by-step explanation:
Given expression:
[tex]-\frac{1s }{20r}[/tex]
r = [tex]-\frac{1}{4}[/tex] , s = [tex]\frac{4}{5}[/tex]
Now;
[tex]-\frac{1s }{20r}[/tex] = [tex]-\frac{s}{20r}[/tex]
Insert the parameters:
= [tex]-\frac{\frac{4}{5} }{20 x (-\frac{1}{4} )}[/tex]
= - [tex]\frac{\frac{4}{5} }{-5}[/tex]
-x - = +
= [tex]\frac{4}{5}[/tex] x [tex]\frac{1}{5}[/tex]
= [tex]\frac{4}{25}[/tex]

Try using Symbolab, I use it all the time it gives the correct answer and it gives good explanations (I use it all the time).
If the slope of line a is -4/3 and the slope of line b is 3/4 line a and line b are perpendicular
A: True
B: False
C: False most of the time
Answer:
hi! so for perpendicular it's negative reciprocal!
so is -4/3 and 3/4 negative reciprocals?
oh and remember reciprocals are flipped!
if you still don't get it let me know aha
Answer:
True
Step-by-step explanation:
e Whenever you need to find the slope of a line, it is always the reciprocal with the opposite sign. For example, if your slope was 5, your slope to make it perpendicular would be -1/5. If you had the slope of -8/5, the perpendicular sope would 5/8.

write an equation of a line (-4,-1) and is perpendicular to the line y=4/3x+6
y =
Answer:
y= -3/4x-2
Step-by-step explanation:
- perpendicular: opposite signs and reciprocal
m= -3/4
point-slope form: y-y1=m(x-x1)
y-(-1)= -3/4(x-(-4))
y+1= -3/4(x+4)
y+1= -3/4x -3
y= -3/4x-2
Find all real square roots of -9

Write the equation of the line that passes through the given points. (-2,2.5) and (0,-4.5)
Answer: y = -3.5x - 4.5
suppose: the equation of the line is y = ax + b ( a ≠ 0 )
because the line passes through (-2;2.5) => 2.5 = -2a + b
the line passes though (0;-4.5) => -4.5 = b
=> b = -4.5
2.5 = -2a + b
=> a = -3.5
b = -4.5
=> the equation of the line is y = -3.5x - 4.5
Step-by-step explanation:
Mario walked at a rate of 5/6 miles every 10 minutes what is his unit rate every mile per hour
Answer:
Mario's unit rate is 5/1
Step-by-step explanation:
We know that Mario walks 5/6 miles per 10 minutes.
We need to find out how many miles Mario walks in 60 minutes (1 hour).
10 * 6 = 60. Which means that we must multiply 5/6 by 6.
[tex]\frac{5}{6} *\frac{6}{1} = \frac{30}6[/tex]
30/6 = 5
Mario walks 5 miles per hour.
To put this in to a unit rate we must put this is a fraction:
[tex]\frac{Miles}{Hour}[/tex]
Substitute:
5/1
Answer:
Mario's unit rate is given by 900 miles/hour
Step-by-step explanation:
We have been given that Mario walked at a rate of 2/3 miles every 10 minutes
We have the relation between speed, time and distance, which is given by
speed = distance/Time
we have,
distance = 2/3 miles
Time = 10 minutes
On substituting these values in above formula, we got
speed 2/3 /10
speed 2/10.3
We have to find the unit rate in mile per hour, so we need to multiply it by 60
Thus, unit rate is given by
1/15 X 60
= 4 miles/hour
struggling a lot pls help!!!!! ASAP
Answer:
Its (-2, 0)
Explanation: This is actually very simple because you just simply go left 2 times towards the middle of the two lines crossing each other, and thats -2. Then after the point doesn't move any farther so its 0.
