C : is an irrational number
Answer:
A
Step-by-step explanation:
The point slope form of the equation is where m is the slope and is a point on the line.
First find the slope by subtracting two points from the line.
To write the equation substitute in:
The answer is A.
Answer:
(2z)^3 or 8z^3
Step-by-step explanation:
"double z:" 2z
"raise the result (2z) to the third power:" (2z)^3 or 8z^3
Answer:
the rate of change is 1/2
Step-by-step explanation:
The rate of change is described by the change in y over the change in x. I'm guessing you meant to put an x after 1/2. The equation you wrote is in y-intercept form, as it gives us the slope and y-intercept. Slope is the same as rate of change. In simple terms, the number beside x is the rate of change. 1/2
Answer:
Question 1). Option C.
Question 2) Option C.
Question 3) Option D.
Step-by-step explanation:
Question 1), A. 7 - (9x + 3) = -9x -4
7 - 9x - 3 = -9x - 4
-9x + 4 = -9x - 4
Left hand side(L.H.S.)≠ Right hand side(R.H.S.)
Therefore, it's not an identity
B). 6m - 7 = 7m + 5 -m
6m -7 = 6m + 5
Again L.H.S.≠R.H.S.
So, it's not an identity.
C). 10p + 6 - p = 12p - 3(p - 2)
9p + 6 = 12p - 3p + 6
9p + 6 = 9p + 6
L.H.S.=R.H.S.
Therefore, it's an identity.
D). 3y + 2 = 3y - 2
L.H.S. ≠ R.H.S.
Therefore, it's not an identity.
Question 2. Part A. 7v + 2 = 8v - 3
7v - 8v = -2 - 3
- v = - 5
v = 5
Part B. 3x - 5 = 3x + 8 - x
3x - 5 = 2x + 8
3x - 2x = 8 + 5
x = 13
Part C. 4y + 5 = 4y - 6
This equation has no solution.
Part D. 7z + 6 = -7z - 5
7z + 7z = -6 - 5
14z = -11
z =
Question 3). 5 + 7x = 11 + 7x
This equation has same coefficient of variable x on both the sides of the equation.
Therefore, equation has no solution.
Option D. no solution is the correct option.
