Answer: Which operation must be performed to move all the constants to the right side of the equation? Subtract 0.4

Then, which operation must be performed to isolate the variable? Divide by -9 on both sides

The solution to the equation is x =0.4

Answer:

x = -0.4

Step-by-step explanation:

We have the equation:

-9x + 0.4 = 4

First, the operation to move all the constants to the right side is subtraction since we would have to subtract 0.4 from each side, let's see this:

-9x+0.4=4\\-9x+0.4-0.4=4-0.4\\-9x=3.6

Now, we have all the constants on the right side of the equation.

Now, the operation we need to perform to isolate the variable is division (since the x has a -9 that is being multiplied by x) we need to do the opposite operation:

-9x=3.6\\\frac{-9x}{-9} =\frac{3.6}{-9} \\x=-0.4

<h3>Thus, the answer to this equation is x= -0.4</h3>

A.   The data in the table represent a function. y=x/2. This is seen as for every value of x in the table, y=x/2(half of it). You can show this further by trying this fact on each value.

B.   For the original function, when x =8, y=x/2=4
For the function given in this part, when x=8, y=3(8)-10
                                                                 y=24-10                                                                                                            y=14
     This means the relation given in this part has a greater value when x=8

C. When x=80, f(x)=3(80)-10
                           =240-10
                           =230

A sports store is having a 20% off sale on skis. The original price of the ski is $560.00
attashe74 [19]

Answer:

Total cost: 486.080$

Step-by-step explanation:

Original Price: 560.000$

Sale: 20%

Discount: 560.000$ * 20% = 112.000$

Discounted Price: 560.000$ - 112.000$ = 448.000$

Tax Rate: 8.5%

Tax: 448.000$ * 8.5% = 38.080$

Tax after Tax: 448.000$ + 38.080$ = 486.080$
