Given a function f(x)=|x+1|-|x -2|

White raven [17]

Answer:

Step-by-step explanation:

$f(x)=/x+1/-/x-2/\\a=/x+1/-/x-2/\\\text{square both sides}\\a^{2}={(x+1)}^{2}+{(x-2)}^{2}-2(x+1)(x-2)\\a^{2}=x^{2}+2x+1+x^{2}-4x+4-2x^{2}+2x+4\\a^{2}=9\\a=\sqrt{9}\\a=+3\text{ or }-3$

$\text{if }a \in \{-3, 3\},\text{the number of solutions is 2}$

$\text{if }a \in \{-\infty, -3\}\bigcup\{\infty, 3\},\text{it is just like saying from infinity to infinity, which is still 2}$

Answer:

solution: x= 0.273, y= 1.909.

Step-by-step explanation:

given system of linear equations : x+3y=64x−6y=6

these can also be splitted or written individually as:

x+3y=6 & 64x−6y=6

the first equation can also be written as, $y=2-\frac{x}{3}$

so, it is line with slope : -1/3 and y-intercept :2

the second equation can also be written as, $y=\frac{32x}{3} -1$

so, it is line with slope : 32/3 and y-intercept : -1

now we can easily draw graphs for these equations using the above interpretation.

graph is in the attachment.

so, the solution is: x= 0.273, y= 1.909.
