Answer:
330.88 m/min
Step-by-step explanation:
rate = distance/time
= 4000 /12.089
= 330.88 m/min
Answer:
The answer is C.
Step-by-step explanation:
Fist you take the letter that represents the TOTAL cost for the computer and the fee, which is the letter t. or (t = ........) then you take the price, or p and you make it (t = p), and lastly, you add the additional fee, which is 25 dollars. t = p + $25
The change in temperature is -28°F
So, Option D is correct.
Step-by-step explanation:
Temperature at day time = 72°F
Temperature at night = 44°F
What number represents the change in number?
Change in temperature = Temperature at night - Temperature at Day
Change in temperature = 44°F-75°F
Change in temperature = -28°F
The change in temperature is -28°F
So, Option D is correct.

Answer:
5x + 4y = - 8
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 )
Given
4x - 5y = 20 ( subtract 4x from both sides )
- 5y = - 4x + 20 ( divide all terms by - 5 )
y = 
x - 4 ← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 
, thus
y = - x + c ← is the partial equation
To find c substitute (- 4, 3) into the partial equation
3 = 5 + c ⇒ c = 3 - 5 = - 2
y = - x - 2 ← in slope- intercept form
Multiply through by 4
4y = - 5x - 8 ( add 5x to both sides )
5x + 4y = - 8 ← equation in standard form
