Answer:

I think that the answer is 19.

Step-by-step explanation:

Writing out the problem

x²+yz

Substituting the given values of the variables

(-3)²+(5)(2)

Simplifying (-3)², which is 9

9+(5)(2)

5 times 2 equals 10

9+10

Graph f(x)=2x 1 and g(x)=−x 4 on the same coordinate plane. What is the solution to the equation f(x)=g(x) ? Enter your answer i

We can equate both the functions to evaluate value of x and that will be the solution of $f(x) = g(x)$ .

The solution is given as: $x = 1$

<h2>Given that:</h2>

$f(x) = 2x+ 1$

$g(x) = -x + 4$

Solution of the equation $f(x) = g(x)$

<h3>Substituting values of f(x) and g(x) in given equation:</h3>

$f(x) = g(x)\\2x + 1 = -x + 4\\\\\text{Adding x on both the sides}\\2x + x + 1 = -x + x + 4\\3x + 1 = 4\\\\\text{Subtracting 1 from both the sides}\\3x + 1 - 1 = 4 - 1\\3x = 3\\\\\text{Dividing both the sides by 3}\\\dfrac{3x}{3} = \dfrac{3}{3}\\\\x = 1$
