Answer:
y = 3x + 3
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 = 
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3) ← x and y- intercepts
m =
=
= 3
The line crosses the y- axis at (0, 3) ⇒ c = 3
y = 3x + 3 ← equation of line
Answer:
the snail travels 30 mm per minute
Step-by-step explanation:
Well 12 cenitmters divided by 4 minutes equals the amount of centimeters the snail travels per minute, which is 3 centimeters (12 / 4 = 3). but be careful cuz we need to convert the 3 cm to mm. 1 cm = 10 mm so 3 cm = 30 mm.
the snail travels 30 mm per minute

Find f(-1):




Answer:
$331.25
Step-by-step explanation:
Given:
The jewelry center bought a pair of earrings for $250
They are going to mark the price of the earrings up 32.5%
Question asked:
How much will they sell the earrings for ?
Solution:
Cost price of a pair of earrings = $250
Mark up value = 32.5% of $250
= 
Now, we can find selling price of a pair of earring by simply adding the cost price and the mark up value.
Selling price = cost price + mark up value
= 250 + 81.25
= $331.25
Thus, they sell the earrings for $331.25
