Plz fas: yuma is solving the inequality 3x−23≥−5.

to solve the inequality, he begins by solving the equation as shown.

which number line represents the solution to the inequality?
pick the box that is right

see explanation

Step-by-step explanation:

Solving the inequality

3x - 23 ≥ - 5 ( add 23 to both sides )

3x ≥ 18 ( dividing both sides by 3 )

x ≥ 6 ← is the solution

Look for a number line that has a solid circle over 6, indicating that x is equal to 6. The line should should extend from 6 to the right indicating that all real values greater than or equal to 6 are solutions.

The required number line is the one on the bottom left

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
