Step 1: multiple the second equation by 2 so that you get -1/4 for the coefficient of y, the same as in equation 1
equation 2 multiply by 2: 1/4 x - 1/4 y=38 ..........name this equation 3
subtract equation 1 from equation 3: (1/4 x -1/2 x)=38-10
-1/4 x = 28
x=-112
plug in x=-112 in any of the equation, you will get y=-264
so the answer is A
Answer:
(1,1)
Step-by-step explanation:
I would just do for the first one 7/16 - 3/16 = 4/16 which is also 1/4 I'm not sure ho2 you estimate it
If a certain place's population is given to be growing at a rate of 4.8% annually, the population after t years from 2003 will become (1.048^t) times the given initial population. This translates to a mathematical equation which is equal to,
At = (584,658(1.048^t)
To find the answer, multiply 8 by 4 to get 32. Now divide 32 by 4 and you should get the answer 8. This will make sure that your answer is correct. And so 32 divided by 4 equals 8.
8*4
Multiply
Final Answer: 32
32/4
Divide
Final Answer: 8
