Answer would either both be 1500:4500 or 1500/4500
Answer: It is closer to 9
Step-by-step explanation: The square root of 84 is 9.16515139
Y can be found by setting the 3 angles in the bottom triangle equal to 180 degrees like so:
45 + 55 + y = 180
100 + y = 180 (Simplify)
y = 80 (Subtract 100 from both sides)
Angles x and y are opposite angles, so they are equal to each other. This means that x = 80 degrees also.
Answer:
Step-by-step explanation:
Refer to attached for points
a) f(-1) = 3 as per graph
b) f(x) = 6
We add horizontal line through point y=6 to find intersections with the graph
Take x-values of those points. The points are x = -3, x = -2, x = 2
I think that is the answer
