Your answer is going to be option C.

I put your equation in the problem into slope-intercept to give me its slope. Then I took the reciprocal of this, because it wants a line perpendicular to the one in the orig. equation, for the new equation.

Then I plugged in the given ordered pair in slope-intercept form and solved for B. Plug that back in and, voila, you get option C as your answer.

HELP!! What is the equation of the graphed line? (y=mx+b)

Anettt [7]

So to fine slope you would use the formula down below:

rise/run

So use a graphed point, 0, -5 and you rise or count up quadrants up to a point and then horizontally move to when you find that point.

So from 0,-5 go up 9 vertically, and you would be on the 4

Go horizontal 3 spots and your on a designated point.

So the rise is four and the run is 3

So 4/3 is the slope

In the y= Mx + b equation you would set the equation like this:

y= 4/3 + -5

The m in this formula stands for the slop and the b stands for the y-intercept

The y-intercept is the point that is on the y-axis and where it starts.

Help, I don’t know how to solve this.

NNADVOKAT [17]

Answer: Angles ABD and BAD (B)

Step-by-step explanation: Angles ABD BAD are not congruent angles, since they are the same angles.

Congruent angles are angles that both measure the same in degrees.

In this case, B is your correct answer since that answer has the same angle and not comparing any 2 angles, just the same one.

Answer:

E: L is perpendicular to a line with slope $-\frac{3}{2}$ .

Lines are perpendicular if the negative reciprocal of the slope is equal. For example, the reciprocal of $\frac{2}{3}$ is $\frac{3}{2}$ (remember, to get the reciprocal, simply switch the numerator and the denominator).

So, the negative reciprocal of $\frac{2}{3}$ is $-\frac{3}{2}$ . This represents the slope of a line that is perpendicular.

Simplify x²-49/3x+21

Vera_Pavlovna [14]

First, you factor and simplify (respectively) the numerator and denominator. Your equation becomes:

$\frac{(x-7)(x+7)}{3(x + 7)}$

Notice, there is a (x + 7) on both the top and the bottom. Because of this, they cancel each other out. What is left is your answer:

$\frac{(x-7)}{3}$
