Answer:
We first have to find the volume of the cube: (0.3 * 0.3 * 0.3) we then get 0.027, then we plug in the numbers for the density formula. D = 18.954/0.027 will give us 702.
I'm not totally sure the exact answer, or if this even helps, but the Y intercept is changing from -2 to 5
A. Slope is defined by rise/run. It looks like the points where it intersects the axes are at (0, 6) and (2, 0)
Basically you take (y-y1)/(x-x1), which in this case could be (6-0)/(0-2), which is -3.
b. The perpendicular slope would be the negative inverse of that.
The inverse of 3 is 1/3, so the negative inverse of -3 would also be 1/3.
c. The parallel slope is the same as the original slope.
d. Plug these points in for y=mx+b.
2=(1/3)(-1)+b
2=-1/3+b
b=7/3. (that's 2 and 1/3).
The equation for that line would be y=(1/3)x+(7/3)
e. The y intercept is found when x=0. But it's also the b in the y=mx+b equation, so the y intercept is (0, 7/3).
In case that's hard to read:
a. Slope = -3
b. Perpendicular Slope = 1/3
c. Parallel Slope = -3
d. y=(1/3)x+(7/3)
e. Y intercept = (0,, 7/3)
Hope that helps!
4+3-1x22
4+3-22
7-22
-15
So -15 is the answer
Answer:
Write an equation for each statement:
:
"one number is four more than a second number."
x = y + 4
:
" two times the first number is four more than four times the second number"
2x = 4y + 4
;
From the 1st equation, substitute (y+4) for x in the above equation
2(y + 4) = 4y + 4
2y + 8 = 4y + 4
8 - 4 = 4y - 2y
4 = 2y
y = 4%2F2
y = 2, the second number
and
x = 2 + 4
x = 6, a number
