Answer:
The slope is 3/4
Please correct me if I am wrong please and thank you
Step-by-step explanation:
I use the slope formula 
Plug in (2,1) and (-2,-2)
1-(-2)/2-2
= 3/4
Answer:
x=-17/5
Step-by-step explanation:
1. Simplify -6x-3x+4+4x−6x−3x+4+4x to -5x+4−5x+4.
21=−5x+4
2. Subtract 44 from both sides.
21−4=−5x
3. Simplify 21-4 to 17.
17=-5x
4. Divided both sides by -5.
-17/5=x
5. Switch sides.
x=-17/5
Hope this helps.
Considering that 12 is a root of the function, the value of coefficient Q is of 12.
<h3>What does it means that x is a root of a function f(x)?</h3>
It means that f(x) = 0.
In this problem, the function is given by:
f(x) = x² - 13x + q.
Since 12 is a root, we have that f(12) = 0, hence:
12² - 13 x 12 + q = 0
q - 12 = 0.
q = 12.

The linear equations are:
- The price of oil from 1990: y = 30 + 5x
- The price of oil from 2005: y = 20 + 2.25x
<h3>How to determine the linear equations</h3>
A linear equation is represented as: y = mx + c
Where:
- m represents the rate
- c represents the initial value.
At the beginning of 1990, we have the following parameters
- Rate: m = 5
- Initial value: c =30
So, the linear equation is:
y = 30 + 5x
At the beginning of 2005, we have the following parameters
- Rate: m = 2.25
- Initial value: c =20
So, the linear equation is:
y = 20 + 2.5x
Hence, the linear equations are y = 30 + 5x and y = 20 + 2.5x
