Answer:
23 because the 24 side is a little bigger than the other side
Step-by-step explanation:
Answer:
X=-1.1 repeated
Step-by-step explanation:
9x - 1= -11
+1= +1
9x = -10
Divide by 9 on both sides
X = -1.1 repeating
Answer:
-6
Step-by-step explanation:
17-6=11
11-6=5
5-6=-1
-1-6=-7
Answer:
12 red cars
Step-by-step explanation:
15% is 0.15
So, you do 80 × 0.15, which is 12.
When we have consecutive values, f(10), f(11), f(12), f(13), f(14), we can make a difference table to determine the degree of f as a polynomial. A quadratic will have a constant second difference:
x 10 11 12 13 14
f(x) 50 71 94 119 146
1st diff 21 23 25 27
2nd diff 2 2 2
We got a constant second difference, so f is a polynomial of degree two.
Answer: This function is quadratic
