Answer:
The answer is the letter B.
The first column represents the x-values, and the second row represents the y-values.
For that reason, if we have:
2x - 7y = -1
x + 3y = -5
Then, the matrix will be given by:
[ 2 -7
1 3]
Then, the third colum will be the equality:
[ -1
-5]
So the correct option is the letter B.
Answer:
x= 60°, y = 80°, z = 40°
Step-by-step explanation:
Look at the line substending 40° and Z°; you would see that both lines are parallel and so their angles are they the same.
Hence z= 40° { corresponding angles of parallel lines}
Similarly;
Look at the line substending 60° and x°; you would see that both lines are parallel and so their angles are they the same.
60° = x° { corresponding angles of parallel lines}
Now looking at the angle between x and y; let's call the angle between them r
And you would observe closely that r = z° = 40°{ vertically opposite angles are equal}
Note that x + r + y = 180°{ angle on a straight line}
y = 180° - ( x + r)
y = 180 - (60+40)
y = 180° - 100°
= 80°
The answer is table D as it is the only one without a repeated input ❤️ hope that helps
Answer:
42.9m
Step-by-step explanation:
The topic is on similar triangle
you are comparing triangle MNP with triangle MAB
side AB is similar to NP
side MA is similar to MN
side MB is similar to MP
now MA = MN - AN
= 67.2 - 32
= 35.2m
MA/MN = MB/MP
35.2/67.2 = x/81.9
cross multiply and solve
x = 42.9m
It's B) A straight line can be drawn through all the points and the line passes through the point (0,0)
This is because in the problem it says that the points are paired and proportional. For example, say you're given the point (3,6). To make this a proportional relationship, you'd have another point in the third quadrant: (-3,-6). When you draw a line from one of these points to the other, it passes through the origin.
