Which statements are true about David’s work? Check all that apply.

The GCF of the coefficients is correct.

The GCF of the variable b should be b4 instead of b2.

The variable c is not common to all terms, so a power of c should not have been factored out.

The expression in step 5 is equivalent to the given polynomial.

In step 6, David applied the distributive property.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63
