Answer:
(-3, 0)
Step-by-step explanation:
We are given two linear functions:
And we want to find the point at which the two lines intersect.
At the point the two lines intersect, their y-values will be the same. In other words, we can set their functions equal to each other and solve for x. Thus:
Substitute:
Solve for x. Subtracting x from both sides yields:
And subtracting 12 from both sides yields:
Thus, the x-coordinate of the point where the two lines intersect is:
To find the y-value, we can use either function. Using the second function, we acquire:
(You will obtain the same result if you use the first function. Try it!)
Thus, the point of intersection is (-3, 0).
Answer:
m is 224°
Step-by-step explanation:
From the figure, we have;
The angle subtended at the circumference, by the arc mWXY, C = 112°
The angle subtended at the center = m
By circle theory, we have;
The angle subtended at the center = 2 × The angle subtended at the circumference
∴ m = 2 × 112° = 224°
m = 224°.
