Answer:

13/48

Step-by-step explanation:

I take the middle sign to be plus.\

3/4//4/5 = 3/4 * 5/4 = 15/16

15/16 - 2/3 =

The lowest common denominator would be 48: 16 and 3 are prime to each other.

45/48 - 32/48 = 13 / 48

Where did the minus come from? I take it that there is a minus sign in front of the 2

Answer: $y^4$ + $\frac{-73}{35}y^2$ - $2$

Step-by-step explanation:

Use FOIL:

$y^4$ + $\frac{-14}{5}y^2$ + $\frac{5}{7}y^2$ + $\frac{-70}{35}$

Make $\frac{-14}{5}y^2$ and $\frac{5}{7}y^2$ have the same numerator:

$\frac{-14*7}{5*7}y^2 =\frac{-98}{35}y^2$

$\frac{5*5}{7*5} y^2=\frac{25}{35} y^2$

Then add like terms and simplify:

$y^4$ + $\frac{-98}{35}y^2$ + $\frac{25}{35} y^2$ + $\frac{-70}{35}$

$y^4$ + $\frac{-73}{35}y^2$ - $2$

If g(x)= x+1/x-2 and h(x)= 4-x, what is the value of (g•h)(-3)?

jek_recluse [69]

Answer:

8/5

Step-by-step explanation:

First find h(-3)

h(-3)= 4-(-3) = 4+3 = 7

Then take this result and find g(h(-3)) = g(7)

g(7) = (7+1)/( 7-2) = 8/5

Simplify the expression 7y+3x+3-2y+6

pishuonlain [190]

Answer:

5y + 3x + 9

Step-by-step explanation:

Whenever something is multiplied by the same variable, you can combine the coefficients. In this case, first you'd move the values with the same variable next to each other, for simplicity:

7y-2y+3x+3+6

Then, combine like terms.

5y+3x+3+6

5y+3x+9
