Answer:
The value of the expression is 57 :D
Step-by-step explanation:
Since x = -14 and y = 3, we need to replace the variables with the given numbers:
-4(x) - y + 4 =
-4(-14) - 3 + 4 =
56 - 3 + 4 =
53 + 4 = 57
Answer:
(-1/2,-5/2)
Step-by-step explanation:
x-y = 2
x+y = -3
---------------
Through Elimination, we can just add the system of equations. The y cancels out and gives us the single equation for x:
2x = -1
x = -1/2
Substitute -1/2 for x in either equation and you get:
(-1/2) + y = -3 Solve for y
y = -5/2

Okay so in the little chart at the bottom of the page, the first 2 are true, and the last one is false.

Answer:
<em>Option c</em>
Step-by-step explanation:
<u>Best Fit Regression Model
</u>
When experimental data is collected, scientists frequently ask themselves if there is a relationship between some of the variables under study. It's crucial in modern times where artificial intelligence technology is trying to find key answers where traditional approaches hadn't before.
One of the most-used tools to find relations between variables is the regression model and its best fit lines to try to find an expression who relates variable x (years from 1960) and variable y (minimum wage requirement) as of our case.
The provided data was entered into a digital spreadsheet and an automatic function was applied to find the best-fit model.
We found this equation:

when rounded to three decimal places, we find

Which corresponds to the option c.
