Malachy was thinking of a number. Malachy doubles it and gets an answer of 91.6. What was the original number?

zubka84 [21]

Answer:

45.8

Step-by-step explanation:

Say the number Malachy was thinking of is x.

Doubling it gives 2x, which we see also equals 91.6. Set these equal to each other:

2x = 91.6

To solve, we divide both sides by 2 and get x = 45.8, which is our answer.

F(x)=-x^2+x f(x)=−x Find f(−1)

STALIN [3.7K]

Answer:

Step 1: Set x to -1 in the first equation

$f(x) = -x^2 + x$

$f(-1) = -(-1)^2 + (-1)$

$f(-1) = -(1) - 1$

$f(-1) = -1 - 1$

$f(-1) = -2$

Step 2: Set x to -1 in the second equation

$f(x) = -x$

$f(-1) = -(-1)$

$f(-1) = 1$
