You just have to plug in each thing:
So f(0):
3(0)^2 - 4 = -4
so its not A
f(-2) and f(2):
3(-2)^2 - 4
3(2)^2 -4
now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4
B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.
The answer is 11.2 which means 11 1/5
List the multiples of 3:
3, 6, 9, 12, 15, 18,21
The ones between 10 and 20 are:
12, 15, 18
The range is the difference between the highest and lowest numbers.
Range = 18 - 12 = 6
Answer:
Alt Int. <s Thm
m<4=45 degrees
Step-by-step explanation:
45=9x
x=5
m<4= 9*5
m^4=45
Answer:
53 + 3g ≤ 65, g ≤ 4
Step-by-step explanation:
To solve for g:
53 + 3g ≤ 65
First, subtract 53 from both sides.
53 - 53 + 3g ≤ 65 - 53
=> 3g ≤ 12
Divide 3 by both sides
=> 3g / 3 ≤ 12 /3
=> g ≤ 4
Therefore, g ≤ 4
Hope this helps :)
