A line passes through the point (2,-5) and is perpendicular to the line with the
equation y = 1/5x+ 5. What's the equation of the line?
OA) y= -1/5x+1
B) y=1/5x+4
C) y = 5x - 2
OD) y = -5x + 5
Answers
Answer:
D) y = -5x + 5
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = 1/5x + 5. Its slope is 1/5. A line parallel/perpendicular to this one will have a slope of -5.
Plug this value (#) into your standard point-slope equation of y = mx + b.
y = -5x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (2, -5). Plug in the x and y values into the x and y of the standard equation.
-5 = -5(2) + b
To find b, multiply the slope and the input of x (2)
-5 = -10 + b
Now, add 10 to both sides to isolate b.
5 = b
Plug this into your standard equation.
y = -5x + 5
This equation is parallel/perpendicular to your given equation (y = 1/5x + 5) and contains point (2, -5)
Hope this helps!

Matt bowled three strings. His scores were 220, 166, and 181. What was his average for the three strings?
Answers
Answer:
189
Step-by-step explanation:
To find his average, we will find the mean. This means we will add 220+166+181 to get 567. When finding the mean we divide the answer but the total amount of addends. In our case we have 3 so we divide 567 by 3.
567 divided by 3 = 189

Robert plays cricket. He hit the ball in such a way that it goes up 180 feet
in 45 seconds. What is the speed of ball in feet per second?
Answers
Answer:
4 feet per second
Step-by-step explanation:
Hi there!
[tex]v=D/t[/tex] where v is velocity (speed), D is distance and t is time
Plug in the known values (D=180 feet, t=45 seconds)
[tex]v=180/45\\v=4[/tex]
Therefore, the speed of the ball is 4 feet per second.

Martika surfs with her friends at Virginia Beach. Her friend, Mark caught 8 waves out of 20 possible waves to ride in the shore. They plan to stay out in the water for 50 more waves. How many of the 50 waves do you predict Mark will catch?
Answers
Answer:
40 waves
Step-by-step explanation:
Prob (Mark catches waves) = Times waves caught / Total waves = 8 / 20 = 4 / 5 = 20%
Predicted waves out of 50 , caught = 4 / 5 or 20% of 50 = (4 / 5) x 50 = 40
Alternatively, multiplying numerator & denominator of wave catch probability ie 4 / 5 with 10 each , we get (4 x 10) / (5 x 10) = 40 / 50 . This also signifies 40 out of 50 waves are predicted to be caught.what is the answer to the question 5/6 * 1/4 =

Una recta atraviesa el punto (8, -1) y tiene una pendiente igual a 5/4.
Escribir una ecuación en forma pendiente intersección para esta recta.
Answers
Answer:
y = (5/4)x - 11
Step-by-step explanation:
Use y = mx + b as your starting point. This becomes y = (5/4)x + b.
Substitute 8 for x and -1 for y and solve for b:
-1 = (5/4)(8) + b, or
-1 = 10 + b.
Then b must be -11, and the desired equation is
y = (5/4)x - 11

Answer:
A cafeteria because all of the other choices would be biased towards the sport/activity that is already occurring.
Step-by-step explanation:
During a wrestling match, people are definitely going to be directed towards wrestling. During a basketball game, people prefer basketball. During a chorus or choir, people prefer choir most likely.
When in a cafeteria, people just sit there and eat or play games or talk.
People are also stationary so people won't be yelling at you to back off when you jump in the stadium for wrestling/basketball and start blasting questions at someone in a headlock.
