Answer:
B
Step-by-step explanation:
(f - g)(x) = f(x) - g(x), then
f(x) - g(x)
= 49 - x² - (7 - x) ← distribute by - 1
= 49 - x² - 7 + x ← collect like terms
= - x² + x + 42 → B
The unit rate in students per computer is 8.
There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.
We are Given that there are 9 computers and 72 students.
We need to find the unit rate of students to computers.
Number of bolts in 9 computers = 72
Number of bolts in 1 computers = 72/9
= 8
So, it will be 8
Thus, the unit rate is 8 students per computer.

Answer:
Step-by-step explanation:
In triangle if two sides are known and included angle is known we can use cosine formula as follows:
Say in a triangle, sides a,b are known and also included angle C
Then the third side
Since all values on right side are known, we can find the third side c easily.
Case II:
If alternately two sides and one angle not included is known. i.e we know a,b and either angle A or B.
then to find third side we use sine formula.
Using the above we can find the unknonwn side c easily.
Answer:
The two numbers are: 42 and 7
Step-by-step explanation:
let x be the one number and y be the other number..
As per the statement:
One number is six times another number. Their difference is 35.
⇒ .....[1]
and
.....[2]
Substitute equation [1] into [2] we get;
Combine like terms;
Divide both sides by 5 we get;
y = 7
Substitute the value of y =7 in [1] we get;
Therefore, the two numbers are: 42 and 7
