Answer:
y= -2/5+5
Step-by-step explanation:
A line must always be written in the form y= and the line given is not. Dividing both sides of the equation by 2 you get y=5/2x-4. This is the equation of the line given.
Perpendicular line have gradients that, when they are multiplied, they are equal to -1
The line given multiplied by the gradient of the line(the one required to find)= - 1. That is 5/2×line= -1.
Dividing both sides of the equation by 5/2 you'll get - 2/5. This is the gradient of the line required.
Using the general formula y=mx+c substitute the gradient into the equation. You'll get something like this y= -2/5x+c.
Substitute the given point into the equation. You'll get something like this 3= -2/5(5)+c.
Calculate the value of c. You'll get c=5.
Substitute the value of c into the original equation. You'll get something like this y= -2/5+5
This is the equation: y= -2/5+5
Answer:
12km/hour
Step-by-step explanation:
The formula for how far he was jogging = Speed
Speed = Distance /Time
In the question,
Distance = 5km
Time = 5/12 hour
Speed = 5km / 5/12 hour
= 5 km ÷ 5/12 hour
= 5km × 12/5 hour
= 12km/hour
Therefore,Ezra was jogging as fast as 12 km/hour
Answer:
sorry i dont under stand it either would it be ok if i repost this
9/8=12/p -----> divide by 12 on both side
9 1. 9
-- x -- = ---- = 8
8 12. 72
p=8
hope this helped:)
Answer: 2300.
Explanation:
There are 1000 millimeters in a meter.
There are 100 centimeters in a meter.
There are 10 millimeters in a meter.
Multiply the number of meters by 1000 giving us 2000.
Multiply the number of centimeters by 100 giving us 300.
Add the numbers together to get 2300.
Bonus info
Milli: 1000
Centi: 100
That information should probably help you with other measurement conversions when you take chemistry or physics.
Have a nice day! :) Good luck with the rest of middle school.
