Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (1, 5)
m =
=
, thus
y =
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 2), then
2 = -
+ c ⇒ c = 
y =
x +
→ C
Answer:
16.2 foot shadow
Step-by-step explanation:
Let the shadow cast by 27 foot tree be x.
Using ratio and proportions,
18 / 30 = x / 27
(18 x 27) / 30 = x
x = 486 / 30
x = 16.2

notice, it was pawned for only 1 month, so the "yearly" rate is for 1 month, which is 1/12 of the year, since a year has 12 moths
you'll get a rate in decimal terms, to get the % amount, just multiply it times 100
They are the same because they have the same slope but are different because they have different y intercepts.
Answer:
15 pencils
Step-by-step explanation:
5/2.5=x/7.5
cross product
2.5*x=5*7.5
2.5x=37.5
x=37.5/2.5
x=15
