Answer:
1000. 100x10=1000 100+100+100+100+100+100+100+100+100+100=1000
100/1000=1/10
Step-by-step explanation:
Answer:
y = -3/1x + 2
Step-by-step explanation:
1. Find the slope
The points I will use are (-1,5) and (0,2), where x1 = -1, y1 = 5, x2 =0, and y2 =2.
y2-y1/x2-x1
2-5/0-(-1) = -3/1
2. Find the y-intercepy
y = mx + b
You can use any x or y point. I'll use (-1,5)
m= slope, which is -3/1
5= -3/1(-1) +b
5= 3 + b
Subtract 3 from 5 and 3 to get 2=b.
3. Rewrite in slope-intercept form
y = -3/1x + 2
A) To find the surface area of a cube, you have to use the formula 6•a^2
meaning you just have to calculate one side and multiply it by six.
541.5 is the surface area of the cube.
B) To find the surface area for just five sides, you'll be doing the same, except instead of 6 it'll be five.
so multiply 9.5 by itself
you get 90.25
Then you multiply 90.5 by 5
You get 451.25
Unfortunately I'm not sure how to do C. good luck
Answer:
-5
Step-by-step explanation:
1. 2+(-3)= -1
2. -1+(-4)= -5
Methods for solving a system of equations:
- elimination
- substitution
- augmented matrix
Ranks of method ( number one being the most preferred method)
1) elimination
2) substitution
3) augmented matrix
Elimination is my preferred method because it is simple and easy to work out and hard to get wrong.
Augmented matrix is my least preferred method because it is easy to get wrong and it requires complex steps to solve a simple equation.
Hope this helps ;)
