Find the length of BC. A.) 14 B.) 9 C.) 2 D.) 3

Mathematics
1 answer:
Vera_Pavlovna [14]3 years ago
7 0

Answer:

A) 14

Step-by-step explanation:

BC is congruent to DC in saying this you can plug the equations to each other and solve for y and then put its back into the equation for BC to get the length.

3y+5=5y-1

subtract 3y from both sides --> 5=2y-1

add 1 to both sides --> 6=2y

now get y alone, divide by 2 by both side --> y=3

plug y in back to 5y-1 --> 5x3-1

15-1

BC = 14

What is the slope of the line through (0,4) and (3,-2)?
Maru [420]

Answer:

The slope would be: -2

Step-by-step explanation:

To find the slope of these two points:

(0,4) and (3,-2)

You would have to use the formula of slope to find it.

The slope formula is:

<h2><u>y₂ - y₁  </u></h2><h2>X₂ - X₁  </h2>

So subsitute in Those two points

(0,4) would be your (x₁ , y₁)

(3,-2) would be your (x₂ , y₂)

So your formula witht he subsituted #'s in it would look like:

<h2><u>-2 - 4</u></h2><h2>3 - 2</h2>

Your answer would be:

<h2><u>-6</u></h2><h2> 3</h2>

Simplified, it is -2

<h3>So your slope is -2</h3>

What is the discriminant of the quadratic equation 2x + 5x2 = 1?
Murrr4er [49]
5x^2+2x-1=0

Delta equation is:

\Delta =\frac{-b\pm\sqrt(b^2-4ac)}{2a}

but we are interested in b^2-4ac because it determines the discriminant

5^2-4*2*(-1)=25+8=33

33>0

which means that discriminant is positive :)
