Answer:

x = 2

Step-by-step explanation:

when you set these two equations equal to each other, you plug in numbers for x until you find one that makes both sides of the equation equal. For example, 2^x - 1 = -x + 5 if you plug a 2 in for x you get 4-1 = -2+5 and both sides of the equation are equal to 3

What is the answer to this equation? 3(x – 2) = 22 – x

denpristay [2]

Use the distributive property on right side and solve:

3x-6=22-x

4x-6=22

4x=28

x=7

So the solution is x=7

Hope this helped!

Write your question here (Keep it simple and clear to get the best answer) If jun has 12 T-shirt 6 pairs of parts, and 3 pairs o

Talja [164]

Answer:

the number of possibilities that can be drace himself up for the day is 216

Step-by-step explanation:

Given that

jun has 12 t-shirts,6 pairs of pants and 3 pairs of shoes

We need to find out the possibilities that can be drace himself up for the day

So here

$= 12C_1 \times 6C_1 \times 3C_1\\\\= \frac{12!}{1!(12 - 1)!} \times \frac{6!}{1!(6 - 1)!} \times \frac{3!}{1!(3 - 1)!}\\\\= \frac{12!}{1!(11)!} \times \frac{6!}{1!(5)!} \times \frac{3!}{1!(2)!}\\\\= 12 \times 6 \times 3\\\\= 216$

Hence, the number of possibilities that can be drace himself up for the day is 216

The same would be considered and relevant too

If f(x) = 4x-3, which of the following is the inverse of f(x)?

GalinKa [24]

Answer:

$\huge\boxed{f^{-1}(x)=\dfrac{x+3}{4}=\dfrac{1}{4}x+\dfrac{3}{4}}$

Step-by-step explanation:

$f(x)=4x-3\to y=4x-3\\\\\text{exchange}\ x\ \text{to}\ y\ \text{and vice versa}\\\\x=4y-3\\\\\text{solve for}\ y\\\\4y-3=x\qquad|\text{add 3 to both sides}\\\\4y-3+3=x+3\\\\4y=x+3\qquad|\text{divide both sides by 4}\\\\\dfrac{4y}{4}=\dfrac{x+3}{4}\\\\y=\dfrac{x+3}{4}\to y=\dfrac{1}{4}x+\dfrac{3}{4}$
