Add the coefficients of like terms.
a) (6x³ +8x² -2x +4) + (10x³ +x² +11x +9)
= (6+10)x³ + (8+1)x² + (-2+11)x + (4+9)
= 16x³ +9x² +9x +13
b) (16x³ +9x² +9x +13) + (3x -2)
= 16x³ +9x² + (9+3)x + (13-2)
= 16x³ +9x² +12x +11
One of them is 30 degrees and the other is 60 degrees
The elapsed time from starting at 10:10 and ending at 10:45, assuming the time of day is the same. Is 35 minutes. If it is not the same time of day, then it would be 12 hours and 35 minutes.
Answer:
120
Step-by-step explanation:
Because we know that the line opposite of the right angle is flat, we know that 60 plus x must equal 180. Rewriting this gives us 180 - 60 = x.
Now, we can just solve for x.
x = 120.
Answer:
y=-4x-8
Step-by-step explanation:
use the equation y-y1=m(x-x1) and solve for y
