<h3>
Answer: Yes it is a function</h3>
===============================================
Here are some reasons why
- We can solve x+2y = 7 for y to get y = -0.5x+3.5; this equation is in slope intercept form y = mx+b. All equations in the form y = mx+b are linear and also a function.
- For any input x, there is exactly only one y value that pairs with it.
- The vertical line test can be used to effectively verify item #2 above. The idea is that it is impossible to draw a vertical line through more than one point on the graph. So it is said to pass the vertical line test.
Answer:
y = 1/3 x + 14/3
Step-by-step explanation:
We can identify the two points shown easily.
They are (-2, 4) and (4, 6).
First, we find the line of the slope of the line that contains those two points.
slope = m = (y2 - y1)/(x2 - x1) = (6 - 4)/[4 - (-2)] = 2/6 = 1/3
Now we use one point and the slope to find the y-intercept.
y = mx + b
Let's use point (4, 6) and the slope, 1/3.
6 = (1/3)(4) + b
18/3 = 4/3 + b
b = 18/3 - 4/3
b = 14/3
The equation is
y = mx + b
y = 1/3 x + 14/3
C=180-A-B=180-67-53=60deg.
by sine rule
b/sinB=a/sinA
b=a/sinA*sinB
=13/sin(67)*sin(53)
= 11.28
c/sinC=a/sinA
c=a/sinA*sinC
=13/sin(67)*sin(60)
= 12.23
Answer:
I think it would be like f x2 so you would reorder the term and get 2f
