Answer:
Yes, it is a function
Step-by-step explanation:
It passes the vertical line test, therefore it is a function.
Answer:
1/2 + 1/4 would be 3/4.
1/2 + 1/6 would be 2/3.
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
4x + 112 = 9x + 72
-112 -112
4x = 9x - 40
-9x -9x
-5x = -40
----- --------
-5 -5
x = 8
Answer:
22 miles.
Step-by-step explanation:
If the question is In a police Chase on the interstate, the suspect's car reached a speed of 88 miles per hour for a total 15 minutes. during that time, how many miles did the Chase last?
According to that we will use distant formula = rate * time
First of all we have to convert 15 mins into hour
1 min = 1/60 hour
15 mins = 15* 1/60
15 mins = 15/60
15 mins = 1/4 hour
Now by using the formula multiply 88 by 1/4
88 * 1/4
We will cancel out 88 and 4 by the table of 4
= 22 miles
Thus the answer is 22 miles....
<span>let's analyze two cases
</span>
case A) <span>2(√x)−4=10
2</span>√x=10+4----> 2√x=14----> √x=14/2----> square---> x=7²----> x=49
case B)
2√(x-4)=10
√(x-4)=10/2-----> square---> x-4=5²----> x=25+4-----> x=29
