Answer:
For a <u>quadratic equation</u>, a graph that has <u>one solution</u> will only intersect the x-axis ONE time. This is seen when the vertex of the parabola <u>rests on the x axis</u>.
Answer:
2 students said only fall
Step-by-step explanation:
Given:
Total number of students = 25
Number of students who like fall season (F) = 12
Number of students who like summer season (S) = 18
Number of students who like both fall and summer season
= 10
To find:
Number of students who like only fall season
Solution:
A set is a well defined collection of objects. A universal set is the set of which all other sets are subsets. It is denoted by U.
According to the venn diagram,
n(only F) = 

So, 2 students said only fall.
Answer:
∠CDF= 70°
Step-by-step explanation:
there's an easier way to do this which is adding the angles ∠EDG and ∠GDF and then subtracting that from 180° but, checking your work in the same process is a little more work.
First, I'd like to find ∠ADB.
- 85°+70°= 155°
- 180°-155°= 25°
- ∠ADB= 25°
Second, add all the angles together.
- 70°+50°+60°+85°+25°= 290°
- 360°-290°= 70°
If

then by this definition,
g(0) = 3 … … … (since -1 < 0 < 2)
and
g(1) = 3 … … … (also because -1 < 1 < 2)
