Answer:

The answer is 33.

Step-by-step explanation:

4x^2 + 13 - 2y, x=3 y=8

In order to evaluate this, you just need to plug the x and y in the expression:

= 4(3)^2 + 13 - 2(8)

= 4(9) + 13 - 16

= 36 + 13 - 16

= 33

If you know anything about combining equations, specifically subtracting, can you please help me :)
Rufina [12.5K]

Answer:

5x - 2y = -2

Step-by-step explanation:

When subtracting one equation from the other, we are essentially just subtracting the left side of the second equation from the left side of the first equation and doing the same thing with the two right sides.

Here, we are subtracting (-7x + 3y) from (-2x + y):

(-2x + y) - (-7x + 3y)

Let's get rid of these parentheses. Remember that when we have a subtraction sign before a parentheses, we need to distribute a -1 to each term within those parentheses:

(-2x + y) - (-7x + 3y) = -2x + y + 7x - 3y = -2x + 7x + y - 3y = 5x - 2y

Now on the right side, we're subtracting 2 from 0:

0 - 2 = -2

Put it all together:

5x - 2y = -2

Hope this helps!

A book seller gains 30% on the cost price by selling a book for $130.Calculate the cost price of the book.​
zlopas [31]

Answer:

Let the cost price be x

  • Selling price, S.P. = 130
  • Gain % = 30%

\rm{C.P. = \dfrac{S.P. \times 100}{100+ gain \% }}

\rm{C.P. = \dfrac{130 \times 100}{100+30}}

\rm{ C.P. = \dfrac{130}{30} }

\large{\boxed{\rm{ C.P. =  \dfrac{13}{3}}}}
