Answer:
A
Step-by-step explanation:
it's a scsle factor of 3.
Answer:
g(-2)=3
g(0)=-5
g(3)=2
Step-by-step explanation:
g(-2)= -2(-2)+ 3(-2) - 5
4-6-5
2-5
g(-2)=3
g(0)= -2(0) + 3 (0)-5
0+0-5
g(0)=-5
g(3)= -2(3) + 3(3)-5
-6+9-5
3-5
g(3)=2

Answer:
Step-by-step explanation:
This problem is just really long- it's trying to confuse you with complicated wording. Here's it demystified:
a)
t = 0 degrees Celsius
d = 1500 meters
Find the temperature, T.
b)
d = 300 meters
T = 26 degrees Celsius
Find the ground temperature, t.
NOTE: The temperatures are different! T is the final temperature and t is the ground temperature.
Step-by-step explanation:
a.
simply add both equations
x + y = 2
-3x - y = 5
----------------
-2x + 0 = 7
x = -7/2
x + y = 2
-7/2 + y = 2
y = 2 + 7/2 = 4/2 + 7/2 = 11/2
b.
1/2 x + 2y = -13
x - 4y = 8
first multiply the first equating by 2
x + 4y = -26
x - 4y = 8
--------------------
2x + 0 = -18
x = -18/2 = -9
x - 4y = 8
-9 - 4y = 8
-4y = 17
y = -17/4
