Answer:
32
Step-by-step explanation:
x^2 + 4y = 16 + 20 = 32
Just do substitution.
Hope this helps.
Good Luck
<span>a. n/4 ≤ -1
Multiply both sides by 4 => n ≤ - 4, which is all the real numbers less or equal than - 4.
That in the real number line is all the numbers to the left of - 4 (including -4)
The matching graph is the B.
b. -10n ≥ -100
Divide both sides by - 10 => n ≤ 10
That is all the real numbers less or equal than 10.
In the real number line it is all the numbers to the left of 10, including 10.
So, the matching graph is the A.
c. 5x ≥ 20
Divide both sides by 5 => x ≥ 4
That is all the real numbers greater or equal to 4.
In the real number line it is all the numbers to the right of 4, including 4.
The matching graph is C.</span>
Answer: x=-3/4
Step-by-step explanation:
Since we know f(x)=6, we can set it equal to the equation.
6=9+4x [subtract 9 on both sides]
-3=4x [divide both sides by 4]
x=-3/4
<u>Answer:
</u>
The average speed that the club is assuming is 50 miles per hour
<u>Solution:
</u>
We know that Distance = Speed × Time.
Here it is given that distance is 325 miles and the time to cover 325 miles is 
hours which is equal to 
hours.
Now to find the average speed mile per hour we use the formula
By cancelling 325 by 13 we get 25
= 25 × 2
= 50 miles per hour
Thus the average speed that the club is assuming is 50 miles per hour.
The correct option is -33/65.
The solution is given below:
