3.2b + 10 = -1.7b - 4.7

b = -3

Step-by-step explanation:

3.2b + 10 = -1.7b - 4.7

add 1.7b to each side

3.2b+1.7b + 10 = -1.7b+1.7b - 4.7

4.9b +10 = -4.7

Subtract 10 from each side

4.9b +10-10 = -4.7-10

4.9b = -14.7

Divide each side by 4.9

4.9/4.9 = -14.7/4.9

b = -3

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
