Here goes another question: 4/5%9/10 and please if you can with procces
love history [14]
When you divide a fraction by another fraction, it is the same thing as multiplying that fraction by its reciprocal.

The reciprocal is the 'flipped' version of a fraction where the numerator becomes the denominator and the denominator becomes the numerator.

for example, the reciprocal of 9/10 is 10/9

Knowing this information 4/5÷9/10 is the same as 4/5×10/9

Now we can solve...

\frac{4}{5} * \frac{10}{9} = \frac{40}{45} = \frac{8}{9}

Answer= 8/9

Given that 2^x = 7, find the value of 4^x-1.
Helga [31]

4=2^2\\\\4^x=(2^2)^x=(2^x)^2=7^2=49\\\\4^x-1=49-1=48


If\ is\ 4^{x-1},\ then\\\\4^{x-1}=\dfrac{4^x}{4}=\dfrac{49}{4}=12\frac{1}{4}

Used:\\\dfrac{a^n}{a^m}=a^{n-m}

Marley was asked to solve x2 - 4x + 9 = 0 using the Quadratic Formula. She found the discriminant first and decided she did not
saveliy_v [14]

We have been given Marley was asked to solve x^2-4x+9 = 0 using the Quadratic Formula. She found the discriminant first and decided she did not need to continue with the Quadratic Formula.

We are asked to determine whether Marley is correct or not.

We know when an equation is in form ax^2+bx+c=0, we can use discriminant to check for the real solutions of equation.

D=b^2-4(a)(c)

If D>0, then the equation will have two real solutions.

If D=0, then the equation will have one real solution.

If D, then the equation will have no real solutions.

Let us find discriminant.

a=1,b=-4\text { and }c=9

D=(-4)^2-4(1)(9)

D=16-36

D=-20

Since -20, therefore, the equation will have no real solutions, so Marley is correct.
