Answer:

(3, 0)

Step-by-step explanation:

we have

7x+3y=21

we know that

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

substitute in the equation and solve for x

7x+3(0)=21

7x=21

Divide by 7 both sides

x=3

therefore

The x-intercept is the point (3,0)

Find the inverse of the function f(x) = (x - 4) 2 - 5 if x ≥ 4.
Serggg [28]
Same here, we do a quick switcharoo on the variables first,

\bf \stackrel{f(x)}{y}=(x-4)^2-5\qquad inverse\implies \boxed{x}=\left( \boxed{y}-4 \right)^2-5
\\\\\\
x+5=(y-4)^2\implies \pm\sqrt{x+5}=y-4\implies \pm\sqrt{x+5}+4=y

4 friends have more than 7 stickers and less than 13 stickers they share the stickers evenly how many stickers NEED HELP
mash [69]
Well,  there can be two answers. So, plus 3 other friends (4 people total) are sharing stickers.
To answer this, all you need to do is count by four. 
4 is not greater than 7 so can not be the answer
4+4 or 8 IS greater than 7 and less than 13 so it can be the answer
4+4+4 or 12 IS ALSO GREATER THAN 7 and less than 13 so it can be the answer
4+4+4+4 is 16 and is greater than 13 so it cannot be the answer
SO it is either 8 or 12 stickers
