Answer:
W=7
Step-by-step explanation:
-3W+27=6
Subtract 27 from both sides to isolate the variable.
-3W=-21
Divide by -3 to solve for W
w=7
Answer:
The correct answer is D. 37.975.
Step-by-step explanation:
Answer:
y+7=1/3(x-3) in point slope
y=1/3x-8 in slope intercept form
Step-by-step explanation:
First put 3x+y=5 in slope-intercept form (y=mx+b)
y=-3x+5
Give that the slope is -3 the perpendicular slope would be 1/3
now using the points (3.-7)
y+7=1/3(x-3) in point slope
y=1/3x-8 in slope intercept form
Two negatives <em>do not </em>equal a positive when adding. If you're in debt and you add more debt, does that get you out of debt?
Two negatives <em>do </em>equal a positive when you're multiplying them together though. This makes sense if you imagine multiplication as squishing or stretching a particular number on the number line. For example, imagine multiplying 2 x 1/2 as <em>squishing </em>the number 2 two times closer to 0. When you multiply 2 by a negative number, say, -1, you squish it so far down that you <em>flip it to the negative side of the number line</em>, bringing it to -2. You can imagine a similar thing happening if you multiply a number like -4 by -2. You squish -4 down to zero, and then <em>flip it to the positive side</em> and stretch it by a factor of 2, bringing it to 8.
The line equation for its slope and one point is:
y - y1 = m(x - x1)
m is the slope, x1, y1 are the point coordinates, so lets substitute:
y - 4 = (1/2)(x - 2)
y = <span>(1/2)x + 3</span>
