Solve for y by simplifying both sides of the equation, then isolating the variable.
y = 1 - x/3

Beginning with <span>x=3-3y and solving for y, the first step would be to move the constant 3 to the opposite side of the equation by subtracting it from both sides, which leaves x-3 = -3y.

Now divide both sides by the coefficient of y, which is -3 to get (x-3)/-3 = y

This could be rewritten as -(1/3)*(x-3) = y or -x/3 + 1 = y</span>

Write a multiplication equation that has a solution of 12. Use tape diagrams to prove that your equation has a solution of 12.

Answer:

The required equation is 3y=36 and the tape diagram is shown below.

Step-by-step explanation:

Consider the provided information.

We need to write a multiplication equation that has a solution of 12.

3y=36

We know we have to split 36 into three equal groups, so we have to divide by 3 to show this algebraically.

3y÷3=36÷3

y=12

Now check this with the help of tape diagram as shown.

Consider the figure 1.

This represents if 36 had to be split into three groups, how big would each group be?

By the tape diagram we concluded that the value of y is 12.

1. use the graph of y = sin θ to find the value of sin θ for each value of θ. 270°please help

You are expected to memorize the general shape of the sine function, including where the peaks and zero crossings are. The graph shows you the value of
sin(270°) = -1
