Answer:

Step-by-step explanation:
so a proportional relationship does not have y-intercepts (ex.: starting price...)
<em>"a small pizza costs $9 and each additional topping costs $.75"</em> is not proportional because it does not start at 0.
<em>"a student earns $12 for each hour she tutors"</em> for example, is proportional because it does start at 0 and does not have anything added to it.
<u>proportional: y = mx</u>
<u>not proportional: y = mx + b</u>

Answer:
40
Step-by-step explanation:
Just look up the conversion factor and set up the proportion.
1 dm = 1/10 th of a meter
x dm = 4 meters. Cross multiply.
1 dm * 4m = x * 1/10 of a meter. Change 1/10 to a decimal.
1 dm * 4 m = x * 0.1 m Divide by 0.1
1 dm * 4 m /0.1 m = x
x = 40 dm
Answer:
no
Step-by-step explanation:
it can have the same y just not the same x, and this answer has two a's in place of x
14.5 x 5.5x 0.5 = 39.875 cubic feet for the wall
brick = .5 x .333 x 0.167 = 0.0278 cubic feet rounded to 0.03
39.875/0.03 = 1329.16
so approximately 1330 bricks are required.
This could be a little different depending on how you round everything off
