Answer:
A
Step-by-step explanation:
Answer: 4.3478 or 100/23
Step-by-step explanation:
Set the y values equal to each other since they are the same unknown (x). You end up with 100=23x, solve for x. Move the 23 over to the other side by using division. x=100/23. If you need it in decimal form, 100÷23=4.347826087
Answer:
A7.45x = y
Step-by-step explanation:
We can use a ratio to solve this problem. Take the total cost of the lunches and divide by the number of lunches.
y = total cost of lunches and
x = number of lunches
74.50 y
-------------- = ------------
10 x
Using cross products
74.5 x = 10 y
Divide each side by 10
74.5/10 x= 10y/10
7.45x = y
Steps?
A graph shows zeros to be ±3. Factoring those out leaves the quadratic
(x-2)² +1
which has complex roots 2±i.
The function has roots -3, 3, 2-i, 2+i.
