Evaluate the expression for x = 2. -9x2 + 11x − 7 =
harina [27]

All you have to do is replace every x with 2 and then solve:

<em>Make to sure to follow the Order of Operations!!</em>

-9x(2) + 11x - 7 =

(-9 × 2 × 2) + (11 × 2) - 7 =

-36 + 22 - 7 =

-14 - 7 =

-21

The answer is -21.

Hope that helps!

A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).
allochka39001 [22]
If you wrote this in point-slope form, it’ll be y+8=-6(x-2).

This equation written in slope intercept form would be y = -6x+4.

He messed up because he was supposed to change the double negative into a positive then solve. He was not supposed to add 8 on both sides.

So, the answer is y = -6x+4.

Hope this helps!

Examine the system of equations.
MrMuchimi

For a system of equations to have no real solution, the lines of the equations must be parallel to each other. The correct option is A.

<h3>What is the System of equations?</h3>

Inconsistent System

For a system of equations to have no real solution, the lines of the equations must be parallel to each other.

Consistent System

1. Dependent Consistent System

For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.

2. Independent Consistent System

For a system of the equation to be an Independent Consistent System, the system must have one unique solution for which the lines of the equation must intersect at a particular.

If the two of the given system of equations are plotted on the graph, then it can be observed that the two lines have different slopes. Therefore, the correct option is A.
