(a+a+6)*2.5=345
2a+6=138
a=132/2
a=66 mph
a+6=66+6=72 mph
Speed of the first car is 72 mph
Answer:
A) Total weekly salary = $1000 + ( 0.05 × s )
B) Yes this is a function
C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.
D) Domain will be [ 0, ∞ ]
Step-by-step explanation:
Given :
Weekly salary = $1000
Commission = 5% of all her sales
Let the number of sales be 's'
thus,
A) Total weekly salary = $1000 + ( 0.05 × s )
B) Yes this is a function
C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.
D) The domain here will be all the possible values of sales i.e 's'
Hence,
sales will always be positive
thus,
domain will be [ 0, ∞ ]

Answer: B: (1-5x²)³, all real numbers
Step-by-step explanation:
The notation 
is called function composition, which is where you pass one function in as the value of another function. In other words, 
.
Since we have the values for f(x) and g(x), let's plug them in.
Hence, the best answer choice is B, as all real numbers would work and it is the cube of 1 - 5x².
Answer:
Angle = 135°
Supplement of the Angle = 45°
Step-by-step explanation:
The complement of an angle, say "x", would be 90 minus that angle:
90 - x
The supplement of an angle, say "y", would be 180 minus that angle:
180 - y
Since we have 1 angle, let it be "x", and that angle is 3 TIMES the SUPPLEMENT of that angle, we can write:
x = 3(180 - x)
Now, we solve for the angle x:
So, the angle is 135°
The supplement of the angle is 180 - 135 = 45°
