Its fairly straightforward. Since the bottom equation only has one unknown,x, because y=1.3, you can plug y in and solve for x. Once you find the value of x, you then have the value for two variables, x and y, and again have one unknown coefficient a. To solve for the coefficient you just plug in your y value (1.3) and your x value (which can be rounded to 0.42). Using a little bit of algebra, you can then solve for a which should be a=2.108. I am not sure if your teacher wants you to solve it this way but you could also use the elimination method or substitution method that you would of learned when discussing system of equations. But no matter which way you do it, the math follows the rules. Hope this helps. I’d suggest you solve it yourself to double check my work.

Answer:
Hopefully, I am correct is it 1/4??
Step-by-step explains:
(Sorry If I am wrong I just guessed.)
Answer:
True, this is a function
Step-by-step explanation:
There is a 1 to one correspondence between x and y
Each x goes to one y, so this is a function
The mean is
A. 8.4
B.5.2
C.9.4
Answer:
Step-by-step Solution:
<u>Subtract or add to obtain your answer.</u>
- b + (−1.9) = −3.7
- => b - 1.9 = -3.7
- => b = -3.7 + 1.9
- => b = -1.8
Hence, the value of b is -1.8
