Answer: C
Step-by-step explanation:
5=Q-11
(Add 11 to both sides)
16=Q
Answer:
20 km?
Step-by-step explanation:
Amount of time it takes for Roscoe to ride his bike m miles is represented by a function: t(m)=m10.5 . Here m is the number of miles which is traveled by Roscoe.
As given that Roscoe rides his bike at least 10 miles and not more than 30 miles, so the domain will lie in this range which is 10 and 30.
So, correct answer is option C: all real numbers from 10 to 30, inclusive .Real because this domain range will contain fractional units also.
Answer:
See below
Step-by-step explanation:
If x=1, then 1-1=0, which implies a vertical asymptote at x=1 since dividing by 0 is undefined.
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
5x + y = 21 → (1)
x - 3y = 9 → (2)
Multiply (1) by 3 and add the result to (2) to eliminate y term
15x + 3y = 63 → (3)
Add (2) and (3) term by term
(x + 15x) + )- 3y + 3y) = (9 + 63)
16x = 72 ( divide both sides by 16 )
x = 4.5
Substitute x = 4.5 into (1) for corresponding value of y
22.5 + y = 21 ( subtract 22.5 from both sides )
y = - 1.5
Solution is (4.5, - 1.5 )
