f(x) = 7
-7^2 + 9(7)= -49 + 63 = 14
6y - 8 ≤ 10
What you do to one side of the inequality, you do to the other side. Add 8 to both sides.
6y ≤ 18
Divide both sides by 6 to isolate y.
y ≤ 3
You need to subtract the total number of pennies they have to the number of pennies they wrapped
Total: 592+128=720
Subtract total to the number of pennies wrapped
720-250=470
You can round 470 up to get 500 pennies that the girls had left
The answer is B
Answer:
To make this easier, first draw or imagine a vertical line at x=2
Find where the vertical line and the graph intersects.
Draw or imagine that point of intersection.
Now, draw or imagine a horizontal line that goes through the point of intersection.
That horizontal line tells us the the value of the function by passing through that mark that says "-2"
The function's value at x=2 is -2.
Have an awesome day! :)
I think it is going to be 3.55 for each notebook and 1.9 for each pen
