How are the real solutions of a quadratic equation related to the graph of the quadratic function?

7 0

The solutions you get when you solve the formula are the corresponding y coordinates to your x value. So say a point on your graph is (2,3). The first number is x and the second is y. (x,y). The number you plug into your function is x,or in this case: 2. The solution to the equation when the x value is plugged in is y, or 3. Therefore, giving you a point on your graph.

Answer:

(10, 8) is the distance.

Step-by-step explanation:

The x's are 10 points away from each other and y's are 8 points away from each other.

By the way, there is no second picture.

Sorry if I'm wrong. I might be more helpful if you upload the second picture.

9x+9y=9. Solve for Y

Alja [10]

Answer:

y = 1 - x

Step-by-step explanation:

9x + 9y = 9 ( divide through by 9 )

x + y = 1 ( subtract x from both sides )

y = 1 - x

Which linear function represents the line given by the point-slope equation y-8=

Nina [5.8K]

Answer:

$f(x)=x+4$

Step-by-step explanation:

we have

$y-8=(x-4)$

This is the equation of the line in point slope form

where

The slope is m=1

The point is (4,8)

Convert to slope intercept form

Isolate the variable y

Adds 8 both sides

$y-8+8=x-4+8$

Combine like terms

$y=x+4$

Convert to function notation

$f(x)=x+4$

Solving for an Unknown Using the Distributive Property

ArbitrLikvidat [17]

Complete Question:

The equation a= 180(n-2)/n represents the angle measures, a, in a regular n-sided polygon. When the equation is solved for n, n is equal to a fraction with a denominator of a – 180. What is the numerator of the fraction?

Answer:

The numerator of fraction is -360

Solution:

Given that,

The equation represents the angle measures, a, in a regular n-sided polygon is:

$a = \frac{180(n - 2)}{n}$

We have to solve the equation for "n"

Rearrange the equation

$a \times n = 180(n - 2)\\\\a \times n = 180n - 360\\\\an - 180 n = -360\\\\Take\ n\ as\ common\ factor\\\\n(a-180) = -360\\\\n = \frac{-360}{a - 180}$

Thus the numerator of the fraction is -360
