7x-3y=-12. Name 2 possible answers for (x,y)

anzhelika [568]

Answer:

x = (-12/7 , 0)

y= (0,4)

Step-by-step explanation:

Plug y=0 into the equation and solve the resulting equation 7x=−12 for x

7x = -12

/7 /7

x = -12/7 and y =0

Plug x=0 into the equation and solve the resulting equation −3y=−12 for y

-3y = -12

/-3 -3

Y = 4 and X = 0

What is the y-intercept of the quadratic function f(x) = (x – 6)(x – 2)? (0,–6) (0,12) (–8,0) (2,0) Mark this and return Save an

juin [17]

the y intercept is the constant term on the x side

-6 * -2 which is 12

we can foil this out to see that

(x-6) (x-2)

x^2 -6x -2x+12

x^2 -8x+12

so the y intercept is (0,12)

PLEASE HELP ASAP!!!

Nonamiya [84]

Answer:

Option C. Yes; y=2x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem

For x=0, y=0

That means ----> the line passes through the origin

<em>Find the value of k</em>

For x=2, y=4

$k=\frac{y}{x}$ ----> $k=\frac{4}{2}=2$

For x=4, y=8

$k=\frac{y}{x}$ ----> $k=\frac{8}{4}=2$

The values of k are equal

therefore

The table represent a direct variation

The equation is equal to

$y=2x$
