I can use a chart by numbers them on the chart because I think 4 should be after the 3
In the equation you have to replace all x's with -1
f (-1) = (-1)^2 - 8(-1) +5
f (-1) = 1 + 8 + 5
f (-1) = 14
the f(-1) stand for the function of -1. it is also equivalent to y
Because it was reflected across the x axis, the distance between the two points is twice the distance of the old point from the x axis, and the distance from the old point from the x axis equals the distance from the new point to the x axis. The distance from the x axis is the absolute value of the x=y value. 7.5 is the y value, meaning the point is 7.5 units away from y=0, the x axis. The new point is twice this from the old point. 7.5 x 2 = 15. The new point is 15 units away from the old point.
Answer:
no
Step-by-step explanation:
Lets she how much money she has
1.00 dollars
5 * .25 = 1.25 quarters
4 * .10 = .40 dimes
7 * .01 = .07 pennies
Add it all together
1 + 1.25+ .40 +.07 =2.72
3.50 - 2.72 =.78
She is 78 cents short
