f(x)= x^2+ 2x – 8
Factor the polynomial by finding 2 numbers that when added together would equal 2 and when multiplied together would equal -8.
The factored form is (x-2) (x+4)
Now find the zero's by solving for the two x's:
x = 2 and x = -4
The answer would be {2,-4}
Answer:
Number of students tickets sold = x = 380 tickets
Number of adults tickets sold = y = 150 tickets
Step-by-step explanation:
Let
Number of students tickets sold = x
Number of adults tickets sold = y
x + y = 530 (1)
3x + 4y = 1740 (2)
From (1)
x = 530 - y
Substitute x = 530 - y into (2)
3x + 4y = 1740
3(530 - y) + 4y = 1740
1590 - 3y + 4y = 1740
- 3y + 4y = 1740 - 1590
y = 150
Substitute y = 150 into (1)
x + y = 530
x + 150 = 530
x = 530 - 150
x = 380
Number of students tickets sold = x = 380 tickets
Number of adults tickets sold = y = 150 tickets
Answer:
Triangle PQR is drawn on a coordinate plane with vertices P (-6, 0), Q (-3, 4), and R(2, 4). What is the length of PR? Is APQRisosceles (two sides of equal length)? Use the drop-down menus to answer the questions. The length of PR is approximately Choose. units. Triangle PQR Choose. an isosceles triangle because Choose.. v are the same -2-1 Choose.. length.
