Answer:
y =
x - 2
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 ) = (4, 0) and (x₂, y₂ ) = (0, - 2) ← 2 points on the line
m =
=
= ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Note the line crosses the y- axis at (0, - 2) ⇒ c = - 2
y =
x - 2 ← equation of line
Answer:
A. 20
Step-by-step explanation:
We know that there are 8 eights in a whole, and a whole is equal to the number 1. The number 2 consists of two wholes, and so we multiply 8 by 2.
8 wholes in each 1 × 2 ones = 16 wholes
Now, we know that the number 2 is equal to 16 wholes, so now we need to find how much 1/2 of a whole is worth.
1 whole = 8 eights, so divided by 2, it would be 4 eights for a half of a whole.
So, we add 16 + 4 to get the result of 20.
8 pm to midnight (12 pm) = 4 hrs
so the temp dropped -16.8 in 4 hrs (because the temp started at 0)
-16.8/4 = -4.2....so it dropped 4.2 every hr.
temp at 9 pm (1 hr after 8) would be (0 - 4.2) = -4.2
Answer:
122 ft^2.
Step-by-step explanation:
This area can be divided into 2 rectangles:
One of size 14 * 4 = 56 ft^2 and
another of size (15 - 4)* 6 = 66ft^2
Total 66 + 56 = 122 ft^2.
