F(x) = -7x + 5x² + 10
x = -2
substitute the x by its value
f(-2) = -7(-2) + 5(-2)² + 10
f(-2) = 14 + 5(4) + 10
f(-2) = 14 + 20 + 10
f(-2) = 44
Answer is 1/25x^5y^2
5^-2 means 5 times 5 =25 the negative means it moves down under division sign
X^-1. Means x moves down also
So then you have 5 x's in the denominatir
Answer:
- 57
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a + (n - 1)d
where a is the first term and d the common difference
Here a = 13 and d = - 2.5, thus
= 13 + (28 × - 2.5) = 13 - 70 = - 57
