Bobby is right, because at x = -2, 3, and 5, the denominator of the function equals zero, which is by definition undefined.
Laura paddles in her canoe at a speed of 5 mph for 5 miles.
As we know that

Substitute the values we get

Laura hops on her windsurfer and sails for 12 miles at a speed of 6 mph.
Again using the above formula we can write

Hence from equation (i) and (ii), we can say total time of travel
Step-by-step explanation:
You can solve systems of equations using either substitution or elimination. For these problems, I recommend elimination. I'll do the first one as an example.
-3x + 16y = 9
-4x + 8y = 12
Multiply the second equation by -2.
8x − 16y = -24
Add to the first equation (notice the y's cancel out).
(-3x + 16y) + (8x − 16y) = 9 − 24
5x = -15
Solve for x.
x = -3
Now you can plug this into either equation to find y.
-3(-3) + 16y = 9
9 + 16y = 9
y = 0
The solution is (-3, 0).
Answer:
i dont know what it means but the right image is 4 times larger than the left image
Step-by-step explanation:
Answer:
A) 150
Step-by-step explanation:
All the angles in a triangle must add up to a total of 180 degrees.
So we can make an equation as given below:
20+10+?=180
30+?=180
?=150
So the missing angle is 150 degrees
