4x²=100
x²=100/4
x²=25
x=√25
x=+5 or -5
The answer is -2x intercept 2,y-intercept:1 because the line is touching the graph where 2 is which identifies that it’s an x intercept and for the -2 it hit a point when the the line goes down to -2 and of course 1 is y because it shows the y on the top.
I hope this help good luck on your test if you need more help let me know
Total number of hours = 15
Let the hours spent tutoring french be x.
Therefore hours spent on scooping ice cream = (15 - x)
Amount: Tutoring french is $15 an hour, total for x hours = 15x
For scooping ice cream it is $10 an hour 10*(15 - x) = 150 - 10x
To make more than $180
15x + (150 - 10x) > 180
15x + 150 - 10x > 180
15x - 10x > 180 - 150
5x > 30
x > 30/5
28.95 is 14.7 greater than 14.25
