The answer is x = 0.5 To get this you do 9-7 which is 2 and then do 2 divided by 4 which is 0.5
The easiest way is to graph it based upon the slope (m) and y-intercept (b), in the standard slope-intercept form: y = m (x) + b.
The line above intercepts the y-axis at y = -2, which is b. The slope (m) = rise/run = (y2-y1)/(x2-x1 ); so for the point (-4, 2) to (-6, 4) is:
(4-2)/(-6--4) = 2/(-6+4) = 2/-2 = -1.
So one form of the equation would be:
y = -1x - 2
Now the other form of an equation is point-slope: y-k = m (x-h), where the point is at (h, k)
and if we pick -5 for x (bc 5 it listed in 3 of the answers), the y at x=-5 looks like around +3
so we get: y-k = -1 (x--5)...
y-3 = -(x+5)... therefore D) is the correct answer:
144 = 12^2
121 = 11^2
so root(130) is between 11 and 12, so is about 11.4 on the number line.
hope this helps :)
Answer:
96
Step-by-step explanation:
y=8.3x
x=4
Substituting x as 4,
y=8*3*4
y=8*12
y=96
Hence, x=4, y=96
