7. e and f
9. c.
sorry didn't understand 8
Yes, that is correct. 10 to the 5th is 100,000. so that divided by 100 = 1000. Hope it helps!
Answer:
(-4, 2)
Step-by-step explanation:
4x+2y=-12
3x+y=-10
Start by dividing the first equation by 2 to simplify it...
2x+y=-6
Then, subtract -2x from both sides to isolate y...
y=-2x-6
Substitute -2x-6 for y in the second equation...
3x-2x-6=-10
Combine like terms...
x-6=-10
Add 6 to both sides
x-6+6=-10+6
x=-4
Plug -4 in for x to solve for y:
3(-4)+y=-10
-12+y=-10
Add 12 to both sides
-12+12+y=-10+12
y=2
(x,y)=(-4,2)
There is a total of 9 spaces between the two.
Meaning that the " 5th" segment is the midpoint.
The answer is : ( 5, -1)
hope it helps you.
