Y - y1 = m(x - x1)
slope(m) = -1/2
(-4,-2)...x1 = -4 and y1 = -2
now we sub
y - (-2) = -1/2(x - (-4) =
y + 2 = -1/2(x + 4) <=====
Answer:
Step-by-step explanation:
A linear equation is written as 
, "m" being the slope and "b" being the y-intercept.
The slope is how many times you rise/run in order to get from one point on the line to the next. You rise (go up/down) 1 unit and run (go left/right) 3 units. Plug in the numbers and you get 1/3.
The y-intercept is where the graph lands on the y-axis, which is 4.
Answer:
Option C. 
Step-by-step explanation:
we know that
Using a Excel tool (Correl function)
see the attached table
The r-value is
Answer:
Option 4. 256 - 64π is the correct option.
Step-by-step explanation:
In the given picture a square is circumscribed about a circle with a side = 2r
where r is the radius of the circle.
Therefore area of the square = (2r)² = 4r² = 4 × 8² = 4 × 64 = 256 in²
Now area of the circle = πr² = π × 8² = 64π in²
Now area of region that is inside the square and outside the circle =
Area of square - area of circle = (256 - 64π) in².
Therefore the answer is (256 - 64π).
Answer:
She can type 225 words in 10 minutes
Step-by-step explanation:
We can find the rate by dividing the number of words by the time
90 words/ 4 minutes
22.5 words per minute
Now to find the number of words in 10 minutes, multiply the rate times the time
22.5 * 10 = 225
She can type 225 words in 10 minutes
