Answer:
<h3>6 degrees</h3>
Step-by-step explanation
Find the diagram attached. In Line geometry, there is a theorem that states that the sum of the adjacent interior angles is 180 degrees. According to the diagram, the adjacent interior angles are 7x- 15 and 24x + 9.
The sum of this angles must give 180 degrees as shown;
7x-15 + 24x + 9 = 180
7x+24x-15+9 = 180
31x-6 = 180
31x = 180+6
31x = 186
x = 186/31
x = 6
Hence the value of x is 6 degrees
The awnser is D to your question
The solution to the system of linear equations is: (−5, −11).
<h3>What is the Solution to the System of Linear Equations?</h3>
The solution to a system is the x and y -coordinates that satisfies the two linear equations.
Given the linear equations:
Line A: y = x − 6
Line B: y = 3x + 4
Now, equating these two equations
x - 6 = 3x + 4
2x = -10
x = -5
y = -11
Hence, the solution is: (−5, −11), because the point satisfies both equations.

Answer:
b) B and D and c) A and C
Step-by-step explanation:
The hypotheses would be:

(Right tailed test at 5% level)
Sample proportions are
Sample A B C D

p diff/SE 0.0757 1.77 1.01 5.80
p value 0.469 0.038 0.156 0.000001
we find that p value is more smaller than alpha, the more accurate the alternate hypothesis.
b) Only B and D provide against the null. Because p <0.05
c) A and C provide no evidence for the alternative because p >0.05
