I'M not sure sorry i just keep getting
1/4x
Answer:
-8m + (-7.7n - 6)
Step-by-step explanation:
You distribute the negative in front of the parentheses, to everything inside of the parentheses, and change the sign to addition.
1)We have to make a line perpendicular to y=2x+3, passing through the point (0,0).
y=2x+3
m=solpe=2
The slope of the line perpedicular to y=2x+3 is m´
m´=-1/m
m´=-1/2
Point slope form:
y-y₀=m(x-x₀)
(0,0)
m=-1/2
y-0=-1/2(x-0)
y=-x/2
Therefore, the line perpendicular to y=2x+3 is y=-x/2.
2)The point on the line y=2x+3 tha is closest to the origin is the point of intersection of the two lines.
y=2x+3
y=-x/2
We can solve this system of equations by equalization method.
2x+3=-x/2
least common multiple=2
4x+6=-x
4x+x=-6
5x=-6
x=-6/5 (=-1.2)
y=-x/2
y=-(-6/5)/2=6/10=3/5 (=0,6)
Therefore: the point of the line y=2x+3 that is closest to the origin is:
(-1.2 , 0.6)

Given Information:
Length of room = l = 8 feet
Width of room = w = 7 feet
Required Information:
Amount of carpet = ?
Answer:
Amount of carpet = 56 ft²
Step-by-step explanation:
Jason wants to replace the carpet in the utility room of his house.
We are given the dimensions of the room and we are asked to find the required amount of carpet in square feet.
The required amount of carpet is given by

where w is the width of room and l is the length of the room.

Therefore, Jason need 56 square feet of carpet for the utility room.
