Given f(x) = -x + 2, find f(-1)

jarptica [38.1K]

f(x) = -x + 2

f(-1) This means that they want you to find the value of f(x) or y when x = -1.

f(x) = -x + 2 Substitute/plug in -1 into "x" since x = -1

f(-1) = -(-1) + 2 (two negative signs cancel each other out and become positive)

f(-1) = 1 + 2

f(-1) = 3

Solve the system of equations given below.

eduard

Answer:

The system of this equation is ( -1, 10) which is Option A.

Step-by-step explanation:

Solve for y in the first equation.

$y = - 5x + 5 \\ - 2y = - x - 21$

Replace all occurrences of yy with -5x+5 in each equation.

$10x - 10 = - x - 21 \\ y = - 5x + 5$

Solve for x in the first equation.

$x = - 1 \\ y = - 5x + 5$

Replace all occurrences of x with -1 in each equation.

$y = 10 \\ x = - 1$

The solution to the system is the complete set of ordered pairs that are valid solutions.

(−1, 10)

Hence, the system of this equation is (-1, 10). 

Option A.
