Y= 10
__________
8/20=(x+4)/15
0.4*15=x+4
6=x+4
X=2
Answer:
a₁ = 10
Step-by-step explanation:
The common difference d is calculated as
d = a₃ - a₂ = - 20 - (- 5) = - 20 + 5 = - 15
Then
a₂ - a₁ = d , that is
- 5 - a₁ = - 15 ( add 5 to both sides )
- a₁ = - 10 ( multiply both sides by - 1 )
a₁ = 10
Very wrong. Not a random selection, only men when you want all students, if they play at school then they probably dont play outside or other way around, biased selection, etc.
Answer:
- d. the x–coordinate of the intersection point
Step-by-step explanation:
The solution of the system with two lines is the x-coordinate of their intersection point.
a. there is only a solution if the lines are identical
- No, it gives infinitely many solutions.
b. both the x–coordinate and the y–coordinate of the intersection point,
- No, only the x-coordinate is considered
c. the y–coordinate of the intersection point
- No, only the x-coordinate is considered
d. the x–coordinate of the intersection point
The answer is B that's the answer
