PART A:
Solve for the slope by solving change in y over change in x. We have (3-(-5)/(-2-2) = 8/-4=-2
PART B:
Change in to y=mx+b: -5y = -2x-10. Divide all terms by -5: y = 2/5x + 2. The slope is 2/5 and the y-intercept is 2.
PART C:
Remembering from part a that m=change in y/change in x, we have the equation: -4=1-(-9)/0-x. If we simplify, we have -4=10/0-x. If we multiply both sides from 1/10 we have: -2/5 = -x. So, x = 2/5.
PART D:
We can use point-slope form first:
y-5=-7(x+1). Then we solve the equation! y-5 = -7x-7. After adding 5 to both sides, we have the equation: y=-7x-2.
The slope should be 3/2, since you rise 3 and go over 2
B) 20 Multiplied by 15 multiplied by 9 is equal to 2,700cm cubed
Let x = The age of Michael
Let 2x-3 = The age of Michaels cousin
X+2x-3=46
x=16+1/3
X = 49 years
I think that’s the answer I’m not 100% sure though
Answer:
<em>75%</em>
Step-by-step explanation:
27 ÷ 36 = 0.75
0.75 → 75%
75% of the crew are men
Hope this helped! :)
