Answer:
The answer is (B)
Step-by-step explanation:
Try out each of the situations. It can't be A, since the 0.9 is less than 1, so it has to be decreasing. This leaves only B and C. Since decreasing by 90 percent is the same as multiplying by 10 percent, the only possible answer left is B.
Hope this helps!
Answer:
x = 
Step-by-step explanation:
x ∝ p
x = kp -------(1)
<em><u>Where k is the constant of proportionality.</u></em>
Now, x = 2 when p = 4
<em>Putting in the above formula</em>
2 = k(4)
<em>Dividing both sides by 4</em>
k = 
=> k = 
Putting k in (1)
x =
<em>Now this is the required equation connecting both.</em>
The slope is 8.5, the y-intercept is 6, y=mx+b was the original formula and m=slope and b=y-intercept :)
Answer:
a. x = total - $5
b. x = $6
c. x = $10
Step-by-step explanation:
a. pen + book = total
Let x = book
$5 + x = total
x = total - $5
b. pen + book = total
Total = 411
$5 + x = $11
x = $11 - $5
x = $6
c. pen + book = total
Total = $15
$5 + x = $15
x = $15 - $5
x = $10
