Answer and Step-by-step explanation:
<u><em>First equation:</em></u>
y = -4x + 9
This equation has a negative slope (a slope that does downwards) and has a positive y-intercept (at (0, 9)).
<em><u>Second Equation:</u></em>
y = -4x - 4
This equation is parallel to the first line because it has the same slope. It also has a negative y-intercept (at (0, -4)).

Answer:
Average price = $3.185
Step-by-step explanation:
Given:
12 notepads = $4.20 each
25 folders = $0.80 each
3 calculators = $19.00 each
Find:
Average price
Computation:
Average price = Total cost / Total number of item
Average price = [(12)(4.20) + (25)(0.80) + (3)(19)] / [12 + 25 + 3]
Average price = [(50.4) + (20) + (57)] / [40]
Average price = [127.4] / [40]
Average price = $3.185
3 , 4 and 6 are not correct
If there are 4 trucks then the first truck weighs x
then x+2tons
then x+4tons
then x+6tons = 32tons
so 4x+12=32
-12 -12
/4 /4
x=5
so plug it back in
truck 1= 5tons or 10,000lbs
truck 2= 7tons or 14,000lbs
truck 3= 9tons or 18,000lbs
truck 4= 11tons or 22,000lbs
