Answer:
3y-15
Step-by-step explanation:
(y-7)3=3y-21
3y-21+6=3y-15
since it is perpendicular line you have to change thing signs of the equation.
x y
(-1,4)
replace the (-1) with x and (4) with y
y=1/2x+b
4=1/2(-1)+b
4=-1/2+b
4+1/2=b
9/2=b
therefore, the perpendicular line is y=1/2x+9/2
Here is the solution of the given problem above.
Given: 2 meters = The length of the taffy that Jen has
1/3 of two meters = measurements of each of her three best friends
? = 1/3 of two meters
? = 1/3 of two meters converted to centimeters
First, we need to get how long 1/3 of 2 meters is. So 2 multiplied by 1/3 is 0.67 meters. So each of her friends gets 0.67 meters. And 0.67 meters in centimeters is 67 meters. 1 meter = 100 centimeters.
In fraction, each friend will get 67/200 centimeters.
