Answer:
m=4 is the correct answer
-8+4x=-20x-25+7x
4x+20x-7x=-25+8
17x=-17 /17
x=-1
X, y - the numbers
The numbers multiply to 100.

The numbers add up to -29.

Substitute -x-29 for y in the first equation:

The numbers are
-4 and
-25.
Answer:
e^xsinx · (sinx+xcosx)
Step-by-step explanation:
f'(x)=e^xsinx · (xsinx)'= e^xsinx · (sinx+xcosx)
Answer:
Y = 59.0°
Step-by-step explanation:
Using the cosine rule in terms of x, y and z
cosY = 
with x = 22, y = 20 and z = 18
cosY = 
= 
=
, thus
Y =
(
) ≈ 59.0° ( to the nearest tenth )
