1. Callie and Elizabeth bought reusable bags for a fundraiser. Callie bought 4 small bags and 2 large bags and spent $52. Elizabeth bought 1 large bag and 3 small bags for $32. Which system of equations best represents the situation where x is small bags and y is large bags? A 4x+2y=32
3x+y=523x+y=52

B 4x+2y=524x+2y=52
3x+y=323x+y=32

C 2x+4y=322x+4y=32
x+3y=52x+3y=52

D 2x+4y=522x+4y=52
x+3y=32x+3y=32

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

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.  

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

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
