System A has ONE real solution
System B has NO real solutions
System C has ONE real solution
Step-by-step explanation: You have to substitute the numbers in for x & y
(0, -5): YES
3x - 4y - 8 = 12
3(0) - 4(-5) - 8 = 12
0 + 20 - 8 = 12
20 - 8 = 12
12 = 12
(4, -2): YES
3x - 4y - 8 = 12
3(4) - 4(-2) - 8 = 12
12 + 8 - 8 = 12
20 - 8 = 12
12 = 12
(8, 2): NO
3x - 4y - 8 = 12
3(8) - 4(2) = 12
24 - 8 = 12
16 = 12
(-16, -17): YES
3x - 4y - 8 = 12
3(-16) - 4(-17) - 8 = 12
-48 + 68 - 8 = 12
20 - 8 = 12
12 = 12
(-1, -8): NO
3x - 4y - 8 = 12
3(-1) - 4(-8) = 12
-3 + 32 = 12
29 = 12
(-40, -34): NO
3x - 4y - 8 = 12
3(-40) - 4(-34) - 8 = 12
-120 + 136 - 8 = 12
16 - 8 = 12
8 = 12
Hope this help you!!! :)
Answer:
Assuming this is for a Conic Section. There is no property as it does not match a conic section.
189
Because you have to turn it into a percentage in order to know how many per 1 percent. So multiply 420 by 100 and get 4.2 then you multiply it by 45 and you get 189 so 179 schools have a horse mascot
Answer:
Some answers include 42, 48, 54, etc.
Step-by-step explanation:
Since the number must be divisible by 2: the number must be even.
For a number to be divisible by 3, the sum of the digits must be divisible by 3.
4+2=6 which is divisible by 3
4+8=12 which is divisible by 3
5+4=9 which is divisible by 3
You can extend this logic for any number from 40 up to 99 since your number must be two digits and greater than 40.
