Answer:
-3c^2 +6
Step-by-step explanation:
The equation will be an identity (0=0) when M is equal to the contents of the parentheses. That polynomial can be used directly, or it can be simplified by combining the c^2 terms.
The contents of parentheses simplify as follows:
... (4c^2 -7c^2 +6) = (c^2(4 -7) +6) = (-3c^2 +6)
14 w /3 + 8/3 - ( 2/3w -1/3 ) =
14w/3 + 8/3 -2/3 w +1 /3 =
12w /3 + 9/ 3 = 3 ( 4w +3) / 3 = 4w +3
the second
3-7m +7m+ 2 = 5
Answer:
The component on the left of original one would be
30 x cos45 =30 x sqrt2/2 =~21.21
The component on the right of original one would also be
30 x cos45 =30 x sqrt2/2 =~21.21
Answer:
An equation of slope:
y = -5x+72
Step-by-step explanation:
The equation of slope intercept is given by:
where m is the slope and c is the y-intercept or initial value.
Let x represents the time in minutes and y represents the height of the water level
As per the statement:
The water level in Noah's water tank is 72 inches high.
At x = 0
y= 72
It is also given that:
The water drains at a speed up 5 inches per minute.
Here, m represent the slope in inches per minute
(as the water drains)
Substitute in [1] we get;
y = -5x+c
Substitute x = 0 then;
72 = -5(0)+c
72 = c
⇒equation becomes: y = -5x+72
Therefore, an equation of slope is y = -5x+72
