Hey!!

What is a standard form in a quadratic equation?

... y = ax² + bx + c

In this equation, x and y are points where as a,b and c are the constants.

We have:

... y = (x+4)(x-6)

... y = (x)(x)+(x)(-6)+(4)(x)+(4)(-6)

... y = x² - 6x + 4x - 24

Combining the like terms.

... y = x² - 2x - 24 <em>Is the standard form. </em>

Hope my answer helps!

Through: (-5, -5), slope=2/5
kakasveta [241]

For this case we have that by definition, the equation of a line in the slope-intersection form is:

y = mx + b

Where:

m: It is the slope

b: It is the cut point with the y axis

The slope is: m = \frac {2} {5}

Thus, the equation is of the form:

y = \frac {2} {5} x + b

We substitute the given point and find "b":

-5 = \frac {2} {5} (- 5) + b\\-5 = -2 + b\\-5 + 2 = b\\b = -3

Finally, the equation is:

y = \frac {2} {5} x-3

Answer:

y = \frac {2} {5} x-3

What is the value of y?<br> 54"<br> A. 126°<br> B. 730<br> C. 63°<br> D. 540
Studentka2010 [4]

Answer: 63 degrees.

Step-by-step explanation:

Angles in a triangle add up to 180 degrees.

Therefore: 54 + y + y = 180

So 54 + 2y = 180

So 2y = 126

Therefore y = 63 degrees.
