Y = 40

Step-by-step explanation:

44 - 66y + 65y + 5 = 9

49 - y = 9

-y = -40

y = 40

Step-by-step explanation:

Step 1: Define

11(4 - 6y) + 5(13y + 1) = 9

Step 2: Solve for y

Distribute: 44 - 66y + 65y + 5 = 9Combine like terms: -y + 49 = 9Isolate y term: -y = -40Isolate y: y = 40

Step 3: Check

Plug in y into the original equation to verify it's a solution.

Substitute in y: 11(4 - 6(40)) + 5(13(40) + 1) = 9Multiply: 11(4 - 240) + 5(520 + 1) = 9Subtract/Add: 11(-236) + 5(521) = 9Multiply: -2596 + 2605 = 9Add: 9 = 9

Here we see that 9 does indeed equal 9.

∴ y = 40 is the solution to the equation.

"if it is my birthday, then it is snowing"

Answer from: Quest

the required function is $y=-x+4$ .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{4-7}{)}=\frac{-3}{3}=-1$

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

$y=mx+b$

where, m is slope and b is y-intercept.

$y=-1x+4$

$y=-x+4$

therefore the required function is $y=-x+4$ . the graph of this function is shown below.
