Answer:
<h2>
Its C. y = 1/4x</h2>
Step-by-step explanation:
Look at the line. See where it attaches at one point and look where it attaches to another, for example, in this expression, it attaches to (0,0) and (4,-1). Then do rise over run, or y over x. This means to do this- y2 - y1 divided by x2 - x1. First, do -1 - 0. Its a double negative, so it becomes positive, thus making it 1 - 0, which is still 1. Then do 4 - 0, which is still 4. Divide 1 by 4, turn it to a fraction, and boom, you've got 1/4x.

Answer:
5
Step-by-step explanation:
first subtract 2 from 10 (10 - 2 = 8)
8 - 2.40 (the first mile) = 5.6
5.6 divided by 1.40 (every additional mile) = 5
#5)
14/4 = 3.5
24.5 / 7 = 3.5
The pair is similar and SF = 3.5
#6)
10/4 = 2.5
21/9 = 2.3333
The pair is not similar because the corresponding sides are not proportional.
Answer:
syd is 23 and dev is 69
Step-by-step explanation:
Let Dev's age be x and Syd's age be y
Since Dev is 3 times older than Syd, we may write
x
=
3
y
Since the sum of their ages is 92, we may write
x
+
y
=
92
Now replacing x with 3y, we get :
3
y
+
y
=
92
Hence
y
=
92
4
=
23
and so Syd is 23 year old.
Back substituting we get Dev is 69 years old.
Answer:
C
Step-by-step explanation:
If the number's a fraction, which this one is, the denominator will always be that little number by the radical, and the whole number will be in the root. Hope this helps!
