Well a normal fraction just divide how it looks for example: 5/10 is just 5÷10= 0.5 to divide a mixed number turn into a improper fraction and just divide for example: 2 3/5 = 13/5 = 13÷5= 2.6

Step-by-step explanation:

First,

(A intersect B) = {1,2,4,5} intersect {1,3,5,7}

= {1,5}

Now,

A'n B = (A) - (A intersect B)

= {1,2,4,5} - {1,5}

= {2,4}

Solve x2 - 8x - 9 = 0. Rewrite the equation so that it is of the form x2 + bx = c.

barxatty [35]

Answer:

x=9,-1 and $x^2+(-8)x=9$

Explanation:

we have been given with the quadratic equation $x^2-8x-9$

we compare the given quadratic equation with general quadratic equation

general quadratic is $ax^2+bx+c=0$

from given quadratic equation a=1,b= -8,c= -9

substituting these values in the formula for discriminant $D=b^{2}-4ac$

$D=(-8)^2-4(1)(-9)=100$

Now, to find the value of x

Formula is $x=\frac{-b\pm\sqrt{D}}{2a}$

Now, substituting the values we will get

$x=\frac{-(-8)\pm\sqrt{100}} {2}= \frac{8\pm10}{2}=9,-1$

And rewritting the given equation by shifting 9 to right hand side of the given equation and taking minus inside the bracket so as to convert it in the form of

$x^2+bx=c$

2. y = 5x2 + 10x – 3

Mice21 [21]

Answer:

x= -7/10 or x= -0.7 , y= 7

Step-by-step explanation:

Find the x-intercept: Find the y-intercept:

y= 5×2+10x-3 y= 5×2+10x-3

0=10+10x-3 y= 5×2+10×0-3

0=7+10x y= 7

-10x=7

x=-7/10
