A beautician sees clients each day to paint full sets of nails. The function g(x) represents the number of finger nails painted,

lions [1.4K]

Yes, the input and output are both possible.

Reason~

Given that the possible solution is (20,20),

Input = x = 20

Output = x = 20

Thus, g(20) = 20, which is clearly possible.

Hope this helps :)

The sum of the roots of 2x squared + 8x -3=0 is?

Helen [10]

According to Vieta's formula, if $x_1,x_2$ are solutions of quadratic equation $ax^2+bx+c=0$ , then:

$\displaystyle x_1+x_2=- \frac{b}{a}$

In our case:

$\displaystyle x_1+x_2=- \frac{8}{2} =-4$

8-5(x+2)<-5 what is the inequality with a line graph

Vadim26 [7]

The expression for the inequality is:

$8-5(x+2)$

We need to find which line represents this inequality. To do that we will use the left side of the inequality and rewrite it as a slope-intercept form. Which is done below:

$\begin{gathered} y(x)=8-5(x+2) \\ y(x)=8-5x-10 \\ y(x)=-5x-2 \end{gathered}$

The line for this inequality is "-5x -2". Where the slope is -5 and the y-intercept is -2. We can graph it as shown below:
