3x+2y=1

x+y=8

Solve for x and y. the equations correspond

3x + 2y = 1 1

x+y=82

x=8 - y 3

subs 3 into 1

3(8-y) + 2y=1

24-3y + 2y = 1

24-y = 1

-y= 1-24

-y= -23

y= 23

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
