Answer:when x=0; y=18

When x=;6 y=0

When x=3; y=9

Step-by-step explanation:

To complete the table for when x=0, you need to make 'y' subject of the formula.

9x+3y=54

3y=54-9x

Divide both sides by the coefficient of y.

y=(54-9x)÷3

y=18-3x

Therefore, when x=0,

y=18-3(0)

y=18.

When x=3,

y=18-3(3)

y=18-9

y=9

When y=0, you need to make x subject of the formula.

9x+3y=54

9x=54-3y

Divide both sides by 9

x=(54-3y)÷9

x=6-y÷3

When y=0,

x=6-(0)÷3

x=6.

Rewrite the quadratic function in intercept or factored form<br> y=4x^2-19x-5
damaskus [11]

Answer:

y = (x - 5)(4x + 1)

Step-by-step explanation:

The given function y = 4x^2 -19x - 5

Here we have to find the AC method.

Identify the value of A, B and C

A = 4 ,  B = -19 and C = -5

AC = 4*-5 = -20

Now find the facotr -20 such that when we add those two factors, we have to get the value of B. That is B = -19

Factors are -20 and 1

1 * -20 = -20

1 + (-20) = -19

y = 4x^2 -19x - 5

This can be written using the factors

y = 4x^2 - 20x + 1x - 5

Now let's factor by group the first two terms, then second two terms.

y = 4x (x - 5) + 1(x - 5)

y = (x - 5)(4x + 1)

That's the answer.

Hope this will helpful.

Thank you.

3. Rhombus KLMN with vertices K(-3, 2), L(1, 4),<br> and N(-5, -2): (x,y) → (x+2, y-5)
Art [367]

The translated vertices of the rhombus are: K(-1,-3), L(3,-1), M(1,-5) and N(-3,-7)

The rhombus is a parallelogram which has all sides equal. the diagonals of a rhombus bisect at right angles. the difference between a rhombus and a square is that none of the angles of a rhombus are 90°.

To translate a figure with given co-ordinates into another figure with a particular translation we simply add or subtract the given values from the coordinates of the available points.

Given co-ordinates of Rhombus are K(-3, 2),L(1, 4),M(-1 ,0)and N(-5, -2).

The translation is given as (x,y) → (x+2, y-5)

So we calculate the coordinates as:

The translated co-ordinate  K(-3, 2)→ K'(-1,-3)

The translated co-ordinate  L(1, 4)→  L'(3,-1)

The translated co-ordinate  M(-1 ,0)→ M'(1,-5)

The translated co-ordinate N(-5, -2)→ N'(-3,-7)

Hence the co-ordinates of rhombus translated by  (x,y) → (x+2, y-5) are  K(-1,-3), L(3,-1), M(1,-5) and N(-3,-7).

My question is what is. 6x +5–2x=-19
Lesechka [4]

Answer:

x=-6

Step-by-step explanation:

Our first step is to combine like terms. We can combine 6x and -2x

4x+5=-19

Now we have to move the variables to one side, and the numerical values to the other. We can do this by subtracting 5 from both sides. (What you do to one side, you must do to the other to keep the equation equal.)

4x=-24

Now we can divide both sides by 4.

x=-6
