Answer:
The range of a set of numbers is the difference between the highest and lowest values. In this case, the highest mark is 45 and the lowest mark is 6.1.1 Therefore, the range is 45 - 6.1.1 = 38.9.

B. C = 89(2) + 75
C. C = 75 + 89
D. C = 75(2) + 89
Answer:
The total cost for the repair is represented by C = 75 (2) + 89 .
Option (D) is correct .
Step-by-step explanation:
As given
An auto repair shop charged $75/h for labor plus an additional $89 for parts.
If the shop worked for 2 h.
C = Represented the total repair cost .
Than the equation becomes
C = 75 × 2 + 89
C = 75 (2) + 89
Therefore the total cost for the repair is represented by C = 75 (2) + 89 .
Option (D) is correct .
41°
65°
74°
a)
x+y2=14
⟹y2=14−x
⟹y=±14−x−−−−−√
Let’s say we plug in x=5
, we will get y=±3
The definition of a function says that one input must give us at most one output. This tells us that from this equation we cannot have y
as a function of x
.
b)
x3−y3=27
⟹y3=x3−27
⟹y=x3–27−−−−−√3
The cube root function gives us one output per input. As a consequence of the previous statement and using the definition of function we can say that from this equation we can write y
as a function of x
.
What is the value of x?
Answer:
Step-by-step explanation:
We know: The sum of the triangle angle measures is 180°.
Therefore we have the equation:
