Quadrilateral ABCD is shown. Quadrilateral A B C D . Side A B has a length 2 y plus x, side B C has length 5 x plus 4 y, side C D has length 3 y plus 5, and side D A has length 7 x minus 2. Angle A B C has measure 55 a minus 3 degrees and opposite angle C D A has measure 4 a plus 9 degrees.

What must the values of m and n be for ABCD to be a parallelogram?

If f(x)=2x+2and g(x)=x^3, what is (g•f)(2)

Which linear equations have an infinite number of solutions? check all that apply.  (x  –  3/7)  =  2/7(3/2x  –  9/14)8(x  +  2)  =  5x  –  1412.3x  –  18  =  3(–6  +  4.1x)(6x  +  10)  =  7(x  –  2)4.2x  –  3.5  =  2.1 (5x  +  8)

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
