Answer:
see explanation
Step-by-step explanation:
f(g(2)) = f(0) = -2
g(f(1)) = g(0) = 0
To be a function every x should have only one y-value.
<span>a. (0,0), (1,1), (2,2), (3,3), (4,4) - We do not see repeating values of x, so it is a function
</span>b. (0,8), (1,6), (2,4), (3,2), (4,0)- We do not see repeating values of x, so it is a function
<span>c. (3,0), (3,1), (3,2), (3,3), (3,4) - We see repeating value of x, that means that one value of x corresponds many values of y , so it is not a function.</span>
7 centimeters is a possible length for the third side ⇒ B
Step-by-step explanation:
Let us revise the triangle Inequality Theorem
- The sum of the lengths of any 2 sides of a triangle must be greater than the length of the third side
- To prove that by easy way add the smallest two sides, if their sum greater than the third side,then the sides can form a triangle
Assume that the length of the third side is x cm
∵ The length of two sides are 7 cm and 10 cm
∵ The length of the third side is x cm
- Put the sum of x and 7 greater than 10 ( x and 7 are the smallest sides)
∴ x + 7 > 10
- Subtract 7 from both sides
∴ x > 3
- Put the sum of 7 and 10 greater than x (7 and 10 are the smallest sides)
∵ 7 + 10 > x
∴ 17 > x
∴ x < 17
- By using one inequality for x (combined the two inequalities in one)
∴ 3 < x < 17
That means the length of the third side is any number between 3 and 17
There is only one answer between 3 and 17
∵ 7 is between 3 and 17
∴ The length of the third side could be 7 cm
7 centimeters is a possible length for the third side

Answer:
below 15 times
Step-by-step explanation:
If the numbers on the spinner are 1, 2, 3, 4, 5, 6 (six numbers) the even numbers are 2, 4, 6 ( three numbers) than 3 out of 6 numbers on the spinner are even.
If Jane will spin the spinner below 30 times the is expected that less than half of the time 30/2 = 15 times will be an even number.
