Answer:
The 3rd
Step-by-step explanation:
y = 4 x - 7
The slope is the number moltipied by x, 4
Hope this helps, have a good day
First, you have to find the midpoint of the segment. Using the midpoint theorem, (which is (x1+x2)/2, (y1+y2)/2 ) the midpoint of that segment in (3,-1)
Next find the slope of the segment 1,0 and 5,-2 using rise over run or deltax / deltay which is a fancy way of saying change in x over change in y.
The slope is 4/2 or 2
When a line is perpendicular to another the slope is the negative reciprocal so the slope of our new line will be -1/2
Now plug in the coordinate (3, -1) to find the y-intercept and the equation of that line will be complete
so -1 = -1/2 (3) +b
-1= -1.5 +b
0.5 = b
The final equation will be -1/2x + 0.5 =y
hope this helps:)
Answer:
x=9
Step-by-step explanation:
90(the angle)-30=60
60-15=45
45/5=9
<u>(5(9)+15)+30=90</u>
Just multiply by 0.15 to get the tip amount and add to your original number. This gives you 32.43
Well, from those 560, 200 are from her salary, and the rest is commissions from sales, so.... 360 is the 5.5% she's got, now, if we take "x" to be the 100% for the sales, then
solve for "x".
