Step-by-step explanation:
180-124=56°
180-56-2x-(180-6x)=0
180-56-2x-180+6x=0
-56+4x=0
4x=56
x=14°
........
2x=28
6x=84
Answer:
7.8cm
Step-by-step explanation:
1cm rep10km
Xcm rep78km
Cross multiply
10xcm=78*1
Xcm=78/10
X= 7.8cm
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:
the last one
Step-by-step explanation:
The first table shows an upward trend (positive correlation).
The second table shows a horizontal line, neither up nor down (zero correlation).
The third table is incomplete, but seems to show as much upward as downward trend, so has a correlation near zero also.
The last table shows a decidedly downward trend, so will have a strong negative correlation.
