3=4m+ b
-1=3m+b
m=4
plug in to either equation,
3=16+ b
b=-13
Thus, C would be the answer.
Change divide sign to multiplication sign, and flip second fraction
= 41/21 × 23/8
multiply top numbers together and multiply bottom numbers together
= (42×23)/(21×8)
=943/168
Answer:
Step-by-step explanation:
Comparing the given y-4=-2/5(x-1) with the standard point-slope formula for the equation of a straight line, we get
y-4=-2/5(x-1)
y-k = (-2/5)(x - 1). Thus, k = 4 and h = 1, and so one point on this new line is (1, 4).
The slope is -2/5.
First, plot a dark dot at (1, 4).
Next, starting with your pencil point on that dot, move your point 5 units to the right and then 2 units down. Plot a dark dot there.
Finally, draw a line through your two dark dots.
The answer will be C-115.75
You have to times 23 by 5.50 which you will get 126.50
Then you have to subtract that by 10.75
You will get C
