Answer:
option 4. The graph has zeroes at x = 15 an x = -15 and it opens upward.
Step-by-step explanation:
we have
This is the equation of a vertical parabola open upward (the leading coefficient is positive)
The vertex represent a minimum
The vertex is the point (0,-225)
The axis of symmetry is x=0 (y-axis)
Find the x-intercepts (values of x when the value of y is equal to zero)
For y=0
square root both sides
therefore
The graph has zeroes at x = 15 an x = -15 and it opens upward.
595 - 35t > 420
-35t > 420 - 595
-35t > -175
t < 5........so she can buy 4 tickets
1/10 is equal to 0.10. Multiply their total tables (200) by the percent (10% aka 0.10), and you get 20. Hope this helps.
Answer: 175 robberies
Step-by-step explanation:
Robberies last year= 243
Robberies has reduced by 28% which means there are (100-28)% = 72% robberies this year.
Number of robberies this year= 72% of 243 = 72/100 × 243 = 174.96 = 175.
There are 175 robberies this year
Three hundred thirty-seven thousand, sixty
