Answer:
28 are 6th
14 and 7th
40% are 8th
Step-by-step explanation:
L1: 2x+4y-3=0 ..........(1)
P: (2,0)
The point on the line L1 closest to the given point P is at the intersection of L1 with L2, which is the perpendicular passing through P.
Slope of L1=-2/4=-1/2
Slope of L2=-1/(-1/2)=2
Since it passes throug P(2,0), we can use the point-slope formula:
(y-0)=2(x-2) =>
L2: 2x-y-4=0.............(2)
Solve for x & y using (1) and (2) to get intersection point required:
(1)-(2)
2x-2x + 4y-(-y) -3 -(-4) =0
5y=-1, y=-1/5
Substitute y=1/5 in equation (1)
2x+4(-1/5)-3=0 =>
2x-19/5=0
x=19/10
=> the point on L1 closest to (2,0) is (19/10, -1/5)
Answer
x = unidentified
Explanation
If 12÷3=4 and 12 = 4×3, that means 6÷0=x and x×0=6.
This isn't possible because any number divided by 0 is unidentified.
Answer:
(4,14) because both lines pass through it.
Step-by-step explanation:
A "solution" to a system of equations is simply a point that both lines pass through.
First image is the solution found through graphing and the second image is the solution found through substitution.
The mean average of all the test runs are 10 miles. Thus, a mean rate of 10 miles per gallon would be more accurate.
