Answer:
5x^3- 6x^2 - 25/y + 18 / y
Step-by-step explanation:
It would be that expression over y.
Sorry if its wrong I'm still learning too:)
24 hours if Mai earns 5.50 each hour
132/ 5.50 = 24
Answer: A) 3x + 5x - 4 = 1
<u>Step-by-step explanation:</u>
The second equation is y + 4 = 5x. Solve this equation for y by subtracting 4 from both sides. --> y = 5x - 4
Now replace "y" in the first equation with "5x - 4".
3x + y = 1
--> 3x + (5x - 4) = 1
Answer:
B. (-3,3)
Step-by-step explanation:
We want to know the solution to the equations, which just means <u>where the two lines intersect.</u>
If we just count the spaces, we can see that they touch at (-3,3). Remember that coordinates are (x,y), so we go left 3 (-3,3) and up 3 (-3,3).
Answer:
Step-by-step explanation:
Let h represent the number of hours of babysitting.
C represents the total cost of babysitting for h hours.
For babysitting, Nicole charges a flat fee of $3, plus $5 per hour. Therefore, the equation would be
C = 5h + 3
Comparing the equation with the slope intercept form, y = mx + c,
The slope = 5
The y intercept = 3
If she babysits for 5 hours, the cost would bee
C = 5 × 5 + 3
C = $28
