$y(y-2)=3\\y^{2}-2y=3\\y^{2}-2y-3=0 \\(y-3)(y+1)=0\\y=3,y=-1$

What is 2/5-1/3 fractions

patriot [66]

You have to make the denominators (bottom numbers) the same via multiplication, it's best to do it to the first number they meet at. that would be fifteen (15)
5×3=15
3×5=15
you then have to multiply the numerators by the respective numbers.
2×3=6
1×5=5
you then subtract the numerators normally
6-5=1
slap back on the denominator
1/15
there's your answer.
(the number you multiply them by isn't the other denominator, it just happens to be the denominators for this equation)

Which function represents a reflection of f(x)=3/8

Leni [432]

Answer:

Step-by-step explanation:

Reflecting a function across the Y axis means replacing x with -x.

First one could *almost* work, if there wasn't the minus sign at the beginning, so it's a no.

Second one is also a no, the original one is always positive, the second one is always negative.

3rd one is reflecting the graph all right, but it's also adding some sort of stretch (try with the point x=1 in both cases, $f(1) = \frac 32$ while $g_3(1) = 2/3$
