Answer:
graph D shows a negative correlation
Step-by-step explanation:
There is no question here.
If we assume you want the plausible graph of Edmund's data, it is graph D. That graph shows decreasing temperature with altitude.
Angle a =40° beacuse they are vertical angle
b will be 180- 40+90=50°
c is making supplementry angle with 65 so c+65=180
c=115°
To answer this item, we assume that the topic is in similar polygons such that the ratio of the corresponding sides should be equal. In this item,
BY/YC = AX/XC
Substituting the known values,
6/10 = 18/XC
The value of XC from the equation is 30. The answer is letter C.
Answer:
5t + 2
General Formulas and Concepts:
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define Expression</u>
4t - 18 - t + 2t + 20
<u>Step 2: Simplify</u>
- Combine like terms (t): 5t - 18 + 20
- Combine like terms (Z): 5t + 2
