Change in y
-------------------
Change in X

Since Y is negative as X goes from left to right, the slope is negative.

An undefined line is vertical (Infinity/0)
Slope of 0 is horizontal (0/Infinity)

x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}

x=2a−b±b2−4ac​​

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

Evaluate. Write your answer in simplified, rationalized form. Do not round.
borishaifa [10]

Answer:

  cos(45°) = (√2)/2

Step-by-step explanation:

The cosine of 45° is the x-coordinate of the point on the unit circle where the line y=x intersects it. That is, it is the positive solution to the equation ...

  x^2 +x^2 = 1

  x^2 = 1/2 = 2/4 . . . . . collect terms, divide by 2, express the fraction with a square denominator

  x = √(2/4) . . . . . . take the square root

  x = (√2)/2 . . . . . simplify

The cosine of 45° is (√2)/2.

Need help with a math question
krek1111 [17]

Answer:

x=13°

Step-by-step explanation:

If BE is an angle bisector, then it divides the angle into two equal angles. This means that

∠ABE=∠EBC

Since ∠ABE=2x+20 and ∠EBC=4x-6, we have

2x+20=4x-6

2x-4x=-6-20

-2x=-26

2x=26

x=13°

I REALLY NEED HELP!!! If someone can answer this quickly and correctly I will give them Brainliest. 1. What is the function rule
Rainbow [258]

Answer:

y= -4x + 3

Step-by-step explanation:

Because the slope is -4/1 which is the same as 4 and 3 is the y-intercept.

Here's the work;

We can just use the first two coordinates which are (0,3) and (1,-1) to get from the x-value 0 to 1 we add 1. and to get from the y-value 3 to -1 we subtract 4. Therefore the slope is -4 and the y- intercept (when x is zero) is 3. Pop that into slope intercept form to get y=-4x +3

Hope that helps and have a great day!

What is the answer to 2b + 8- 5b + 3 = -13 + 8b - 5
Alborosie

Answer:

2 8/11 = b

Step-by-step explanation:

2b + 8 - 5b + 3 = -13 + 8b - 5

combine like terms

11 - 3b = -18 + 8b

add 3b

11 = -18 + 11b

add 18

29 = 11b

divide by 11

2 8/11 = b
