Answer:

y=4

Step-by-step explanation:

its asking which one you can answer without any more context, in this case its y=4 because all the other ones evolving x lead to a rabbit hole and will take you in circles.

Answer:

y=x

Step-by-step explanation:

direct variation form is y = kx where 'k' is the constant of variation

y=4 This has no 'x' variable

y = 1/3x+4 The constant of variation is 1/3 but then 4 is added, so no direct

y = x³ The 'x' variable must be to the power of one

Slope:-

$\\ \sf\longmapsto m=\dfrac{5-1}{-2+6}=\dfrac{4}{4}=1$

Point-Slope form

$\\ \sf\longmapsto y-y_1=m(x-x_1)$

$\\ \sf\longmapsto y-1=1(x+6)$

$\\ \sf\longmapsto y-1=x+6$

$\\ \sf\longmapsto x-y+7=0$

How is the graph of y=2(3)^x+1 translated from the graph of y = 2(3)^x

umka2103 [35]

y=2(3)x+1

−

y=2(3)x

y-y=2(3)x+1−2(3)x

the answer would be 0=1

but if it is asking u if it is false or true it is

0=1 is false, therefore the system of equations has no solutions

Which ordered pair is a solution to the system of equations?

melisa1 [442]

Answer:

(-2, -3)

Step-by-step explanation:

We assume your system of equations is ...

2x - y = -1
2x -4y = 8

You can subtract the second equation from the first to get

... (2x -y) -(2x -4y) = (-1) -(8)

... 3y = -9 . . . . . collect terms

... y = -3 . . . . . . divide by 3 . . . . this is sufficient to identify the correct answer

Substituting into the first equation, we have ...

... 2x -(-3) = -1

... 2x = -4 . . . . . add -3

... x = -2 . . . . . . .divide by 2

Now, we're sure the answer is (x, y) = (-2, -3).
