Answer:
200 Miles
Step-by-step explanation:
Solving:
47.98+.14x=51.98+.12x
.14x=4+.12x
.02x=4
x=200
Checking:
47.98+.14(200)
75.98
51.98+.12(200)
75.98

Please check the formatting when posting. I'm assuming these are the equations:
y=x^2 - 2
y=−x
Step-by-step explanation:
We can either graph the equations or solve them. I use graphing - see the attachment. The lines intersect at (-2, 2) and (1,-1)
<u>1. Graphing</u>
See attached graph
(-2, 2) and (1,-1) are the intersection points
<u>2. Solving</u>
y=x^2 - 2 Use y=−x in this equation:
-x = x^2 - 2
0 = x^2 + x - 2
0 = (x+2)(x-1)
x = -2 and +1
(-2, 2) and (1,-1) are the intersection points
Step-by-step explanation:
The first step to finding the median is to sort the numbers from small to large.
3, 7, 17, 19, 20, 21, 31, 43, 46
then you find the middle number, equal numbers on other sides.
20 is in the middle because that leaves 4 on each side.
Answer:
Step 4
Step-by-step explanation:
Step 4 was incorrect
- Square root both sides must take 16 under root as well but it is missed
- It should have 4 instead of 16
Add all the pieces:
6 + 4 + 3 + 5 = 18
In 18 pieces, there are 4 raisins, so in 9 pieces, there are 2 raisins.
