Answer:
x = 5
Step-by-step explanation:
Given
2x - 2 + 5 = 13, that is
2x + 3 = 13 ( subtract 3 from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Answer:
216m^3
Step-by-step explanation:
find the area of the face 12m
times the face by the length
18×12=216
Answer:
-4a+48
Step-by-step explanation:
Using the distributive property, you would multiply -4 with the values inside the brackets, which are a and -12.
-4*a + (-4*(-12))
= -4a+(48)
= -4a+48
Hope this helps!
In mathematics, a constant function is one defined in
which a function whose output value (y) is the same for every value of the
input variable (x). Therefore this means that whatever is the value for x, the
value of y would always be the same. Hence we can say that the function is a
straight horizontal line in a Cartesian plane.
Since the value of y does not change, and the average rate
of change has the formula:
average rate of change = (y2 – y1) / (x2 – x1)
So y2 – y1 = 0 therefore average rate of change is also
zero.
Hence to complete the sentence:
For a constant function, the y-coordinate is <u>the same</u> for
every pair of points selected, so the average rate of change always has a value
equal to <u>zero</u>.
