For this, plug in 4 into the x placeholder to solve:

$f(4)=2*4^2+4*2-7\\ f(4)=2*16+8-7\\ f(4)=32+8-7\\ f(4)=33$

<u>In short, f(4) = 33.</u>

Solve the system of equations. If the system has no solution, say that it is inconsistent. Graph the lines of the system.

Romashka-Z-Leto [24]

Answer:

The solution to the system of the equations will be:

$x=3,\:y=1$

Step-by-step explanation:

Given the system of the equations

$x+y=4$

$x-y=2$

solving the system of the equations

$\begin{bmatrix}x+y=4\\ x-y=2\end{bmatrix}$

$x-y=2$

$-$

$\underline{x+y=4}$

$-2y=-2$

solving

$-2y=-2$

Divide both sides by -2

$\frac{-2y}{-2}=\frac{-2}{-2}$

$y=1$

$\mathrm{For\:}x+y=4\mathrm{\:plug\:in\:}y=1$

$x+1=4$

$x=3$

Therefore, the solution to the system of the equations will be:

$x=3,\:y=1$

F(x)=x2+5x-1 is shifted 3 units left the result is g(x) what is g(x)?

Len [333]

Replace the x in x^2 + 5x - 1 by x+3:-

g(x) =
(x+3)^2 + 5(x+3) - 1

= x^2 + 6x + 9 + 5x + 15 - 1

= x^2 + 11x + 23

- thats g(x)
