$\bf y=(2x-3)^5(2-x^4)^3\\\\

Help me pls also the answer must be a mixed number

Oksi-84 [34.3K]

Answer:

2 wholes and 5/26

Step-by-step explanation:

convert the mixed number to improper fraction

= -19/6 / -13/9

since there is 2 negatives and (-)/ (-) means your answer is positve

to divide by a fraction multiply by the reciprocal of that fraction.

19/6 x 9/13

reduce 6 and 9 to 3 and 2 becuase both have a GCF of 3.

19/2 x 3/13

multiply 19/2 x 3/13

= 57/26

= 2 wholes and 5/26

= 2.1923076

How to solve this problem by classifying systems of equations<br> 3x+4y=36<br> -5x=35-3y

marissa [1.9K]

Answer:

x=-32/29

$y=9\frac {24}{29}$

Step-by-step explanation:

3x+4y=36 Equation 1

-5x+3y=35 Equation 2

Multiplying equation 1 with 3 (value before y in equation 2) and equation 2 with 4 (value before y in equation 1) we obtain equations 3 and 4 as follows

9x+12=108 equation 3

-20x+12y=140 equation 4

Subtracting equation 3 from equation 4 we obtain

-29x=32

x=-32/29

To find the value of y, we substitute the value of x into equation 2 as initially given in the equation

-5(-32/29)=35-3y

-5(-32/29)-35=-3y

$y=9\frac {24}{29}$
