Answer:
y = x² − x + 3
Step-by-step explanation:
Quadratic equation is:
y = ax² + bx + c
Pick three points and plug in. I'll choose (-2, 9), (-1, 5), and (0, 3).
9 = a(-2)² + b(-2) + c
5 = a(-1)² + b(-1) + c
3 = a(0)² + b(0) + c
9 = 4a − 2b + c
5 = a − b + c
3 = c
We know c = 3, so substitute into the first two equations:
9 = 4a − 2b + 3
5 = a − b + 3
0 = 4a − 2b − 6
0 = a − b − 2
Solve by elimination or substitution.
b = a − 2
0 = 4a − 2(a − 2) − 6
0 = 4a − 2a + 4 − 6
0 = 2a − 2
a = 1
b = -1
Therefore:
y = x² − x + 3
Answer:
The answer is No.
Step-by-step explanation:
Zeituni's standard deduction on her federal income tax return is $5700.
she paid $4670 in state taxes and $1180 in mortgage interest last year, totaling to :
So, no, she should not use her standard deduction because it is less than the deduction she will get from itemizing.
Count the squares in between each letter.
Point Q is 6 units from Point R
Point R is 7 units from Point T
Point T is 3 units from Point S
For the area, it is easiest to take the area of each of those shapes and then add them.
(3*7/2) + (6*7)
10.5 + 42 = 52.5 Square Units
