SIZIF [17.4K]3 years ago

Answer:

(f/g)(8) = -13/75

Step-by-step explanation:

f(x) = 3 - 2x, so f(8) = 3 - 2(8) = -13.

g(x) = 75 for all x.

Therefore, (f/g)(8) = -13/75

How to write -2x + y = -3 in slope intercept form? Preferably with steps.
Montano1993 [528]

Answer:

y = 2x - 3

Step-by-step explanation:

Start by writing out the given equation.

-2x + y = -3

The goal is to isolate the variable y.

For this equation, all you need to do is add 2x to each side.

-2x + y + 2x = -3 + 2x

Therefore, the answer is y = 2x -3.

I don't know if you are are familiar with the equation y = mx + b, but here's a little refresher. m is the slope, or in this case 2. b is the y-intercept, or in this case -3.

The equation y = mx + b is slope intercept form, so if you know this, you should be able to write any equation in slope intercept form.

Hope this helps!

-56x + 49y= -14

- 56x + 56y=64

105y=50

y=0.48

-8x+7(0.48)=-2

-8x+3.36=-2

-8x=-5.36

Find the remainder when 1 + 2 + 2^2 + 2^3 + ... + 2^100 is divided by 7.<br><br> Thanks in advance!
Firlakuza [10]

Answer:

3.

Step-by-step explanation:

This is a geometric series so the sum is:

a1 * r^n - 1 / (r - 1)

= 1 * (2^101 -1) / (2-1)

= 2^101 - 1.

Find the remainder when 2^101 is divided by 7:

Note that 101 = 14*7 + 3 so

2^101 = 2^(7*14 + 3) =  2^3  * (2^14)^7 = 8 * (2^14)^7.

By Fermat's Little Theorem  (2^14) ^ 7 = 2^14 mod 7 = 4^7 mod 7.

So 2^101 mod 7 = (8 * 4^7) mod 7

                           = (8 * 4) mod 7

                            = 32 mod 7

                            = 4 = the remainder when 2^101 is divided by 7.

So the remainder when 2^101- 1 is divided by 7 is 4 - 1 = 3..

What is the inverse of the function​
sleet_krkn [62]

Answer:

x^2-10x+31

Step-by-step explanation:

y=\sqrt{x-6}+5

x=\sqrt{y-6}+5

\sqrt{y-6}+5=x

\sqrt{y-6}+5-5=x-5

\sqrt{y-6}=x-5

\left(\sqrt{y-6}\right)^2=\left(x-5\right)^2

\left(\sqrt{y-6}\right)^2

=\left(\left(y-6\right)^{\frac{1}{2}}\right)^2

=y-6

\left(x-5\right)^2

=x^2-10x+25

y-6=x^2-10x+25

y-6+6=x^2-10x+25+6

y=x^2-10x+31
