Step-by-step explanation:

$g(x) = 2x - 5$

$h(x) = 3x + 7$

To determine $g(h(x))$ , wherever you see an $x$ in $g(x)$ , replace it with the equation $h(x)$ :

$g(x) = 2x - 5$

$g(h(x)) = 2(h(x)) - 5$

$g(h(x)) = 2(3x + 7) - 5$

$g(h(x)) = 6x + 14 - 5$

$g(h(x)) = 6x + 9$

What is the vertex of the quadratic function f(x)=x2+6x+16? Write your answer

Olenka [21]

Answer:

The vertex of the quadratic function is:

$(x_{v}, y_{v})=\left(-3,\:7\right)$

Step-by-step explanation:

Given the function

$f\left(x\right)=x^2+6x+16$

As the vertex of the form $y=ax^2+bx+c$ is defined as:

$x_v=-\frac{b}{2a}$

As the quadratic function of parabola params are

$a=1,\:b=6,\:c=16$

so

$x_v=-\frac{b}{2a}$

$x_v=-\frac{6}{2\cdot \:1}$

$x_v=-3$

Putting $x_v=-3$ to determine $y_v$

$y_v=\left(-3\right)^2+6\left(-3\right)+16$

$y_v=3^2-18+16$

$y_v=9-2$

$y_v=7$

Therefore, the vertex of the quadratic function is:

$(x_{v}, y_{v})=\left(-3,\:7\right)$

Your mom pays you $10 a week plus $5 for every A you make on a test. If you want to make $35 one week, how many A's do you need

steposvetlana [31]

you have to make 5 A's, this is because 35-10=25 25/5=5 and 5x5 = 25 + 10= 35

final answer: 5 A's
