Question

y = -9x^2
y^2 = 3x

find y and x

Answer 1

you still here?

Answer 2

y= -9x2
y2= 3x so from this y= +/- sqrt(3x) than we get that -9x2= +/- sqrt(3x)t
what if squared result 81x4= 3x divide by 3x and we get 27x3 =1
x3= 1/27
x3= 3 on exponent (-3)
x= (3 on exponent (-3)) on exponent 1/3
x= 3 on exponent (-3*1/3) = 3 on exponent (-1)
x=1/3
so than y= -9(1/9) = -9/9 = -1

x= 1/3
y= -1

Answer 3

this is understandably ?

Answer 4

i got it =D thank you

Answer 5

1/27 = 1/3 on exponent 3 because 3 on exponent 3 is 27 so but because 27 is on denominator so for there is 3 on exponent minus 3 = 1/27

Answer 6

right ?

Answer 7

so when we h

Answer 8

we have one term cubed equal a

so like x on exponent 3 = a than x= cube root x what equal x on exponent 1/3

Answer 9

ok ?

Answer 10

and if we have one term x on exponent a and this all on exponent b so than we get xon exponent a*b

Answer 11

x on exponent a * b

Answer 12

ok ???

Answer 13

yeahh i got it now :) i understand you steps thank you so much <3
