Y *x =20
y +x =9
rewrite 1st eq. as y = 20/x
subsituute that into 2nd eq.
20/x +x =9
multiply each term by X
20 +x^2 = 9x
subtract 9x from each side:
x^2 - 9x +20 = 0
now factor:
(x-5) (x-4) = 0
solve for x
5-5 = 0
4-4 = 0
so X can be 4 or 5
replace x into equations and solve for Y
so when X = 4, Y = 5
When X = 5, Y = 4
x= 5,4
y = 4,5
Answer:
I dont have graphing abilites biy i hope this gave u the answe
Step-by-step explanation:
ok so u see the 5 put that on the y axis(positivey-axis) and you see the negative 3 put that inbetween that right before the positive two(make it almsot hit the point but not exactly

The function
is piecewise continuous, since both <em>cx</em> ² and <em>cx</em> - 3 are polynomials. <em>f(x)</em> itself is continuous if both pieces meet at the same defined point. In other words, the limits of <em>f(x)</em> as <em>x</em> → 2 from either side have the same value of <em>f </em>(2) = <em>c</em>•2² = 4<em>c</em>.
We have
so in order for <em>f</em> to be continuous, we need
4<em>c</em> = 2<em>c</em> - 3 → 2<em>c</em> = -3 → <em>c</em> = -3/2
