Directly proportional to x
z=kx
And inversely proportional to y
z=kx/y we are given the point (x,y,z) of (3, 6, 9.5) so
9.5=3k/6 now multiply both sides by 6
57=3k divide both sides by 3
19=k so now that we know the constant of proportionality:
z=19x/y, and we want to solve for z when x=8 and y=12 so:
z=19(8)/12
z=12 2/3 exact
z≈12.667 (rounded to the nearest thousandth)
Answer:
-6<x<0
- -
Step-by-step explanation:
make them less than or equal to signs, I don't know how to do that on a computer, I hope I am correct
point one on the left is -6, point 2 on the right is 0 (in terms of the x-axis, that's what domain is )
when there is arrows in the graph, the x/y is always in the middle.
Good luck! Hope I'm not late!
Answer:
D. Quadrant IV
On the coordinate plane, you would go to the right two points, and then down 6, leading to quadrant IV
1. Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. To answer this question, plug in the values they have given you.
y=mx+b
y=1/4x-5
2. To write an equation in slope-intercept form when given two points, use m=y2-y1/x2-x1
Remember: in an ordered pair, x comes first then y.
Plug the y- and x-values in. So, y2=6, y1=2 and x2=-2, x1=9
6-(-)2/-2-9= - 4/11.
The slope of your next equation would be m= - 4/11
Answer: B) 1/6•3=1/2
Step-by-step explanation:
quotient means division
which means 1/2 / 3
which equals 1/6
This is the only equation with 1/2, 3, and 1/6
