Ayard is equal in length to three feet. the function f(y) takes a measurement in yards (as inputs) and returns a measurement in feet (as output). what number will the function return if the input is 10.5?

Answer will be 31.5

Step-by-step explanation:

It is given in the question :

1 yard = 3 feet.

If we represent this as a function F(y) = 3y

Then we have to calculate the value of function for y = 10.5

To get the value of function at y = 10.5, we will replace y by 10.5.

F (10.5) = 3 × 10.5 feet

            =  31.5  feet

Therefore, output value of the function is 31.5 when input value is 10.5

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
