Yup=1/5x in this case
Now simply give values to x
X. -10. -5. 0. 5. 10
Y. -2. -1. 0. 1. 2
Using trial and error
x^4+5x^2-36 factors to (x-2)(x+2)(x^2+9)
2x^2+9x-5 factors to (x+5)(2x-1)
so
(x-2)(x+2)(x^2+9)(x+5)(2x-1)=0
set each to zero
x-2=0
x=2
x+2=0
x=-2
x^2+9=0
x^2=-9
x=3√-1
x=3i
x+5=0
x=-5
2x-1=0
2x=1
x=1/2=0.5
roots are
x=-5-2,0.5,2, and the imaginary root 3i
You started with a total of 28 muffins
<h3>How to determine the amount you started with?</h3>
From the question, the given parameters are:
Proportion carried away = 16 of the total muffins
Proportion carried away = 4/7 of the total muffins
The above parameters implies that
4/7 of the total muffins = 16
Represent the amount you started with x
So, we have the following representation
4/7 of x = 16
Express as products
4/7x = 16
Make x the subject
x = 7 * 16/4
Evaluate
x = 28
Hence, the total number of muffins is 28

$ 130. I got this by multiplying ten by four and 18 by 5 and adding then together. Hope this helps!
