Answer:
28
Step-by-step explanation:
90 - 62 = 28
To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.
Basically the quesiton asks
f(2)=32 for which function?
put 2 for x and see which simplifies to 32
A. 4(2+3)^2-68=4(5^2)-68=4*25-68=100-68=32 we are done
A is answer
The value of b is the y intercept or when the line crosses the y axis
this only happens when the value of x=0
so just look for the ordered pair in the table with x=0 and y=b
so if you had a table and saw
(0,3)
(x,y)
so the point where x=0 is at point (0,3) y=3
therefor b=3
basically look for the matching y value for when x=0
