3x + y = -3
-2x + y = 7
Use elimination method
Subtract both equations
5x = -10, x = -2
Plug in -2 for x (any equation)
3(-2) + y = -3
-6 + y = -3
y = 3

Solution: x = -2, y = 3
Or as a coordinate: (-2, 3)

The function f is defined by f(x)=2.1x−1.7. Use this formula to find the following values of f. f(x+2)

Yuki888 [10]

The value of $f(x+2)=2.1x+2.5$

Step-by-step explanation:

Given: The function $f(x)=2.1x-1.7$

Using this formula, we need to find the value of $f(x+2)$

Hence, we need to substitute $x$ by $x+2$ to find the value of $f(x+2)$

$f(x+2)=2.1(x+2)-1.7$

Multiplying the term $(x+2)$ by $2.1$ , we get,

$f(x+2)=2.1x+4.2-1.7$

Adding the constant term,

$f(x+2)=2.1x+2.5$

Thus, the value of $f(x+2)$ is $f(x+2)=2.1x+2.5$
