A line has a slope of -1/2 and a y-intercept of –2. What is the x-intercept of the line? –4, –1, 1 ,4

grin007 [14]

To get the x-intercept, we simply set y = 0 and solve for "x".

now, we have the slope and the y-intercept, well, let's plug those two in the slope-intercept form, reason why is called that anyway,

$\bf y=\stackrel{slope}{-\cfrac{1}{2}}x\stackrel{y-intercept}{-2}\implies 0=-\cfrac{x}{2}-2\implies \cfrac{x}{2}=-2\implies x=-4$

Anna71 [15]

Answer:

26.2 points

Step-by-step explanation:

To find the average, find their total number of points and divide by the number of games

total points/number of games

To find their total points, add all their points together

35+31+31+10+24=131

Then, divide by the number of games (5)

131/5=26.2

So, they scored an average of 26.2 points

Answer:

It is proved that $f(x)g(x)=|x|=|x-4|-4$ .

Step-by-step explanation:

Given functions are,

$f(x)=|x|$

$g9x)=|x-4|-4$

To show,

$f(x)g(x)=|x|=|x-4|-4$

Consider,

$(fg)(x)=f(g(x))=f(|x-4|-4)=||x-4|-4|$

now if,

$x>4\implies x-4>0$ then $(fg)(x)=||x-4|-4|=|x-4|-4$

$x$ then $(fg)(x)=||x-4|-4|=||-(x+4)|-4|=|x+4-4|=|x|$

Hence the reslt.
