Answer:

The value of x in all the cases is $ \frac{22}{4} $.

Step-by-step explanation:

The given equation is:

$ 4x + 10 = 32 $

a. Add 4 on both the sides. The equation becomes $ 4x + 14 = 36 $

The operation of addition (or subtraction) done on both the sides of the equation will not alter the value. They will still be equal. However, adding a non - zero term to only one side of the equation will result in the equation becoming unequal.

b. Equivalent Equations are those equations which have the same roots or solutions. Note that, the equations $ 4x + 10 = 32 $ and  $ 4x + 14 = 36 $ have the same solution. Then these equations can be named 'equivalent equations'.

c. Subtraction:

Subtract any number from both the sides of the equation, say, 5.

$ \implies 4x + 5 = 27 $. The solution is still not altered.

Multiplication:

Multiply through by 2. We get: $ 8x + 20 = 64 $. The value of x is still the same.

Division:

Divide through out by -2. The solution is unaltered.

Note that operations of Multiplication and Division are to be done by non -zero numbers. Otherwise it would be altered.

If f(x)=×^2+7x-5 and you divide by x-2, What is the quotient and remainder?
katrin [286]

Answer:

The quotient is : x+9

The remainder is : 13

Step-by-step explanation:

The question requires you to perform the long division method;

This will be;

x-2\sqrt{x^2+7x-5}

start with the x term in x-2 and the first term in the function, x², to get x then multiply the x with x-2 to get x²-2x and perform the operation below;

x-2√x²+7x-5 -----------to first get x and then multiply x*[x-2]⇒x²-2x

    -  x²-2x+0 ------------perform subtraction of like terms

---------------------

            9x-5  ----now divide this answer by x-2 ,starting with x and 9x

----------------------This will give , 9 then multiply  9 by x-2 to get 9x-18 and perform the subtraction operation as;

             9x-5

      -      9x-18

------------------------

                     13

So the answer will be; x+9 remainder 13

1500(1.07)

<em>= 1605</em>
