X=one dollar
y=5 dollar
x=3y
1x+5y=40
3y+5y=40
8y=40
divide 8
y=5
x=3y
x=3(5)
x=15
15 one dollars
5 five dollars
Since the sides are equal and it is a right triangle then use pythagorean theorem with a and b as both the same- you get 2a^2=16^2 solve for a and you get square root 128. Area of a triangle is .5 base times height and the base=height in this triangle so it is .5 times square root 128 squared which is 64 units squared
Answer:
t
Step-by-step explanation:
t
Answer:
C.
Step-by-step explanation:
The function (f+g)(x) is the sum of the two functions:
(f+g)(x) = f(x) +g(x) = (ln(2x) -15) +(3sin(x) -7)
= ln(2x) +3sin(x) +(-15 -7)
(f+g)(x) = ln(2x) +3sin(x) -22
