Mathematics
1 answer:
marshall27 [118]3 years ago

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.

Solve the system of equations algebraically. Show all of your steps
Katyanochek1 [597]
I am going to explain this using the substitution method, considering it appears to be the best in this situation.

We know (from the bottom equation) that y can equal 3x+20. Using this knowledge, we substitute the y in the top equation for 3x+20. Now, we have an equation that looks like this:

3x+20=x^2+2x

Now we need to move x to one side and then do some radicals (square roots).
Subtract the 2x on the right (since it is smaller, negatives = NONONO), which will give you

x+20=x^2

Now, we take the square root of both sides to get

rad(x+20)=x

Now we have to simplify. 20 doesn't have a square root, but 4 goes into 20, and 4 has a square root of 2. This now becomes

2rad(x+5)

This doesn't simplify any further... we have a problem... no way to isolate x as far as my knowledge goes... Sorry, can't help you any further than that, but another person or your teacher might be able to. R.I.P...

Which of the following equations corresponds to the graph below?
Alexus [3.1K]
Hi,
Your equation is y=-3/8x+3 because if you do rise over run you get a slope of -3/8 and the y intercept is 3.

Hope this helped!

What is the length of the longest side of a triangle that has vertices at (-2,6) (-4,6) and (-4,4)?
zalisa [80]

Length (2, 6) to (-4, 6) is sqrt((x2 - x1))^2 + (y2 - y1)^2) = sqrt((-4 -2)^2 + (6 - 6)^2) = sqrt((-6)^2 + 0) = 6

Length (2, 6) to (-4, 4) is sqrt((-4 - 2)^2 + (4 - 6)^2) = sqrt((-6)^2 + (-2)^2) = sqrt(36 + 4) = sqrt(40)  = 2sqrt(10) units

Length (-4, 6) to (-4, 4) is sqrt((-4 - (-4))^2 + (4 - 6)^2) = sqrt(0^2 + (-2)^2) = 2

So the length of the longest side is 2sqrt(10) units

Anyone know what Find f(6) means???
zvonat [6]

I believe that the question is referring to f(x) [f(x)=y , x=x] meaning it is asking for the <u>x value of 6</u>.
