Opposite of an integer is also known as additive inverse of an integer
The additive inverse for -5 is +5
Hope it helps
Equation 1) 2x - 3y = -1
Equation 2) y = x -1
Rearrange equation 2 so that x and y are on the same side. To do so, you subtract x from both sides.
2) -x + y = -1
1) 2x - 3y = -1
Multiply ALL of equation 2 by 2.
2) 2(-x + y = -1)
Simplify.
2) -2x + 2y = -1
1) 2x - 3y = -1
Add equations together.
-y = 0
So, y = 0
Plug in 0 for y in the first equation.
2x - 3y = -1
2x - 3(0) = -1
Simplify.
2x - 0 = -1
2x = -1
Divide both sides by 2.
x = -1/2
(-1/2 , 0)

Answer:
B. The center is at 2
Step-by-step explanation:
Answer:
The average rate of change is = - 4
Step-by-step explanation:
If y = f(x) is a function then the average rate of change for f(x) between the interval a ≤ x ≤ b is given by
.
Now, in this case the function is given by f(x) = - 4x + 40 and the interval is 1 ≤ x ≤ 3.
Therefore, f(1) = - 4(1) + 40 = 36 and f(3) = - 4(3) + 40 = 28
So, the average rate of change is =
(Answer)
Answer:
b
Step-by-step explanation:
The correct answer is (B). The correction will decrease the mean because 8 is less than 18 and will decrease the standard deviation because the value, 8, is closer to the mean than the value 18.
