F(x+1)+f(x+2)=2x+3; f(x)=?

Rama09 [41]

Answer:

$F=\frac{-xf+f+2x}{x+1};\quad \:x\ne \:-1$

Step-by-step explanation:

$1. \mathrm{Subtract\:}f\left(x+2\right)\mathrm{\:from\:both\:sides}\\
F\left(x+1\right)+f\left(x+2\right)-f\left(x+2\right)=2x+3f-f\left(x+2\right)

$

$2. \mathrm{Simplify}\\
F\left(x+1\right)=-xf+f+2x\\
$

$3. \mathrm{Divide\:both\:sides\:by\:}x+1;\quad \:x\ne \:-1\\
\frac{F\left(x+1\right)}{x+1}=-\frac{xf}{x+1}+\frac{f}{x+1}+\frac{2x}{x+1};\quad \:x\ne \:-1$

$4. \mathrm{Simplify}\\
F=\frac{-xf+f+2x}{x+1};\quad \:x\ne \:-1$

Final Answer: $F=\frac{-xf+f+2x}{x+1};\quad \:x\ne \:-1$

Stephen Curry's record during the 2017 - 2018 NBA final game is made up of 2-point shots and 3-points.

grandymaker [24]

Answer:

x = 12 ( two points shots )

y = 7 ( three points shots )

Step-by-step explanation:

Let´s call "x" two points shots, and "y" three points shots, then

x + y = 19

2*x + 3*y = 45

We have to solve a two-equation system for x and y

y = 19 - x

2*x + 3 * ( 19 - x ) = 45

2*x + 57 - 3*x = 45

- x = 45 - 57

-x = - 12

x = 12

And y = 19 - 12

y = 7

Kori bought 56 boxes of tiles from the home improvement store, which was es 4/7 of the total number of boxes that they had. How

dimaraw [331]

Answer:

98 boxes

Step-by-step explanation:

If 56 is $\frac{4}{7}$ of the total, we can set up an equation like this:

$56=\frac{4}{7}*T$

Where T is the total number of boxes.

Solving for T gives us the answer:

$56=\frac{4}{7}T\\T=\frac{56}{\frac{4}{7}}\\T=56*\frac{7}{4}\\T=98$

There were 98 boxes in total.
