Answer:
The pencils at store A cost more
Step-by-step explanation:
The complete question in the attached figure
store A
we have
This is a proportional relationship between the total cost (y) and the number of pencils (x)
The constant of proportionality is equal to the slope
The slope or unit rate is equal to
Store B
This is a proportional relationship between the total cost (y) and the number of pencils (x)
The constant of proportionality or slope is equal to
For (6,3.06)
substitute
The linear equation at store B is
<u><em>Verify each statement</em></u>
case 1) The pencils at store A cost more
The statement is true
Because, one pencil at store A cost $0.55 and one pencil at store B cost $0.51
case 2) The pencils at store A cost $0.27 each
The statement is false
Because, one pencil at store A cost $0.55
case 3) The pencils at store B cost $0.30 each
The statement is false
Because, one pencil at store B cost $0.51
case 4) The pencils at store B cost more
The statement is false
Because, pencils at store A cost more
Answer:
the difference is 14
Step-by-step explanation:
subtracting 3x2 4x – 5 from 7x2 x 9 results in a polynomial
Subtract
Multiply negative inside the parenthesis
Now we subtract 4x^2 -3x from the result
