Answer:

All real numbers

Step-by-step explanation:

-2(y - 4) = 20 - 2y - 12

Start by distributing -2 inside the parentheses.

-2y + 8 = 20 - 2y - 12

Combine like terms on the right side of the equation.

-2y + 8 = 8 - 2y

Subtract 8 from both sides of the equation.

-2y =- 2y

Divide both sides by -2 to isolate y.

0=0

This is a true statement, so there are infinite solutions.

What is the standard form of a quadratic function passing through the points (2,4) , (3,5) and (4,3)
Sladkaya [172]

The standard form of a quadratic function is y = 3/2x² + 17/2x - 7

<h3>How to determine the quadratic equation?</h3>

From the question, the points on the quadratic equation are given as

(2,4), (3,5) and (4,3)

The standard form of a quadratic equation is represented as

y = ax² + bx + c

So, we have

Point (2,4):

4a + 2b + c = 4

Point (3,5):

9a + 3b + c = 5

Point (4,3):

16a + 4b + c = 3

Solving using an online calculator. we have

a = 3/2, b = 17/2 and c = -7

Substitute a = 3/2, b = 17/2 and c = -7 in y = ax² + bx + c

y = 3/2x² + 17/2x - 7

Hence, the equation is y = 3/2x² + 17/2x - 7

PLEASEEEE HURRYYYY!!!!<br><br>find the slope, y and x-intercept of<br>f(x)=4 ​
Tju [1.3M]

i'd say it would be 4 over 1         4/1    so you go up 4 and to the right 1 if they were negative then it would be the oposite way around.

(10x -20) (6x + 8)° <br>what is the value of x<br>​
Hoochie [10]

Answer:

X=12

Step-by-step explanation:

Add the two equations together and equate them to 180 due to the geometrical reason that angles on a straight line add up to 180.

10X-20+6X+8=180 (collect like terms)

10X+6X=180-8+20

16X=192 (Divide both sides by 16)

X=12

Hope that helps :)
