Answer:

Your first step in solving the system would be to substitute the value of a variable into one of the equations

Step-by-step explanation:

We know that x = 2y + 2 and y = -1/3x + 4, so we could insert one of these values as the variable in one of the equations

If we were to insert -1/3x + 4 for y, our new equation would be:

x = 2(-1/3x + 4) + 2 (as you can see, the value of y was inserted into the equation)

What is the equation of the parabola, in vertex form, with vertex at (-2,-4) and
Arlecino [84]

Answer:

Step-by-step explanation:

The distance between the vertex and the directrix is 4 units, that means that p = 4 in the equation

(y-k)^2=4p(x-h) and h and k are the coordinates of the vertex. Filling in:

(y+4)^2=4(4)(x+2) which simplifies to

(y+4)^2=16(x+2) choice C

A scientific calculator has 42 buttons. There are twice as many grey buttons as orange buttons. There are two more white buttons
Arlecino [84]

Answer:

x + 2x + 2x + 2 + 4x + 4 = 42

Step-by-step explanation:

Let us assume the number of orange buttons be x

So, the grey buttons be 2x

The white buttons would be 2x + 2

And the black buttons be 2(2x + 2) i.e. 4x + 4

Also the total is 42 buttons

So, the equation is

x + 2x + 2x + 2 + 4x + 4 = 42
