Answer:
7 4/6 - 5 5/6 = 1.83 or 1 5/6
Hope This Helps!
The question is unclear, so I'm going to go with this being the original question:
5x-2y=8
From this starting point we can rearrange to find the gradient of the line.
y= (5/2)x +4
Therefore the line l, has gradient -2/5, from here we can see that the line must have equation y = (-2/5)x
Answer:
43 years
Step-by-step explanation:
So its kind of an absolute value problem so you have to look at it like the distance from 0 A.D.
27+16=42
.25x88= 22 problems
or:
100÷25=4
so each problem would be 4 points each.
4×22=88
Grace got 22 problems correct
An equation in point-slope form that passes through point P(a,b) is as follows:
y-b=m(x-a) where m=slope, a,b are coordinates of point P.
For a line to pass through P(4,-8)
the equation will look like:
y-(-8) = m(x-4)
simplify left side
y+8=m(x-4)
The given equation has a slope of m=-1/2, so the slope of a line perpendicular to it has a slope of -1/m = -1/(-1/2)=+2
Now go through the answer choices:
a. y+8=2(x-4) => passes through P(4,-8) and has a slope of 2. so TRUE
b. y-4=2(x+8) => has a slope of 2, but passes through (-8,4), which is not P so FALSE
c. y+8=(1/2)(x-4) => passes through P(4,-8), but has the wrong slope (a reflection, not perpendicular) so FALSE
d. y-8=(1/2)(x+4) => passes through a wrong point (-4,8) and has the reflected slope (not perpendicular) so FALSE
