Which of the following equations satisfies that y is a function of 2? Give your answer as a comma-separated list of the labelling letters, such as A, B,C.
A: 4cy - 61 = y + 5
B: y2 - 51 = 6
C: y = 6 -3.
D: y2 + 2y = -1
E: 1 + y = 7
F:5 - 6y +3=0
G: y = 2.-5
H: y10 = 81 - 1

  A, C, F

Step-by-step explanation:

A : 4xy- 6x = y + 5

B: y^2-5x = 6

C: y^3 = 6-3x

D: y^2 + 2y =-x

E: |x+y| = 7

F: 5x - 6y + 3 = 0

G: |y| = 2x - 5

H: y^l0-8x- 1

 Which equations graph as a function of x.

Even-degree polynomial terms in y, and absolute-value expressions involving y can result in a given x-value being mapped to multiple y-values. When that is the case, the relation is not a function.

The relations that are functions of x are ...

  A, C, F

The others are not, because ...

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
