Subtract (7x^5-12x^2y+33y^2) from (5x^5-5x^2y+9y^2) simplify your results:

hoa [83]

Answer:

- 2 $x^{5}$ + 7x²y - 24y²

Step-by-step explanation:

( 5 $x^{5}$ - 5x²y + 9y² ) - ( 7 $x^{5}$ - 12x²y + 33y² ) =

5 $x^{5}$ - 5x²y + 9y² - 7 $x^{5}$ + 12x²y - 33y² =

( 5 $x^{5}$ - 7 $x^{5}$ ) + ( - 5x²y + 12x²y ) + ( 9y² - 33y² ) =

- 2  $x^{5}$  + 7x²y - 24y²

$(m^{2} -m+3)+(m-1)$
$= m^{2} -m+3+m-1$ . . . . . . . . (opening the brackets)
$= m^{2} -m+m+3-1$ . . . . . . . . (collecting like terms)
$= m^{2} +2$

9. Krista and Emily wrote an equation of a line that is parallel to the line y = 3x - 1 and passing

Andre45 [30]

Step-by-step explanation:

Hey there!

The equation, of a st. line that passes through point (5,9) is,

$(y - y1) = m1(y - y1)$

Put the values,

$(y - 9) = m1(x - 5)$

It is 1st equation.

Now, another equation is,

y = 3x-1.........(ii)

Comparing the equation with y = mx+c.

Slope (m2)= 3

As per the parallel lines,

m1=m2=3

Putting,

the value of m1 in equation(i)

(y-9)= 3(x-5)

y-9= 3x - 15

y = 3x - 6.

So, Krista equation is correct.

Hope it helps...
