Equation M: y = x + 4

1 answer:

4 0

Solve the system

y = x + 4
y = 3x + 6

Note that both equations have been solved for y. Thus, you can set y = y, or

x+4=3x+6. Simplifying, -2 = 2x, or x = -1.

Another way to look at this would be x + 4 = 3x + 6.

2) 8q+6=4q-14 What is The answer ?

Charra [1.4K]

Answer:

q=-5

Step-by-step explanation:

8q+6=4q-14

Remove q from one side

8q+6=4q-14

-4q -4q

4q+6=-14

Remove 6 from both sides

4q+6=-14

-6 -6

4q=-20

Divide 4 to isolate q

4q/4=-20/4

q=-5

What is the equation of the quadratic function that has vertex (-3, 1) and passes through the point (-2, 4)?

Marat540 [252]

Vertex form: $y=a(x-h)^2+k$ , with (h,k) as the vertex.

For this, we will be using vertex form. Firstly, plug the vertex into the vertex form equation:

$y=a(x-(-3))^2+1\\y=a(x+3)^2+1$

Next, we need to solve for a. Plug in (-2,4) into the x and y coordinates to solve for a as such:

$4=a(-2+3)^2+1\\4=a(1)^2+1\\4=a+1\\3=a$

Putting our equation together, it's $y=3(x+3)^2+1$ 

*Additional section*

Standard form: $y=ax^2+bx+c$

Converting to standard form as such:

$y=3(x+3)^2+1\\y=3(x^2+6x+9)+1\\y=3x^2+18x+27+1\\y=3x^2+18x+28$
