Please help with the middle question!!
Answer: D) The relation R is a function because for each input there is exactly one output
There's not much else to say other than what choice D already does. Visually we can use the vertical line test to confirm if we have a function or not. If we can pass a single vertical line through more than one point on a curve, then the curve isn't a function. The graph is said to have failed the vertical line test. Otherwise, the relation passes the vertical line test and we have a function.

By 2016 the money spent on internet advertising in the country was projected to exceed the amount spent on tv advertising if it is estimated that 0.6 million dollars more will be spent on internet advertising and 2016 and the total amount spent on internet and tv advertising is expanded to be 150 billion dollars find the amount of money for projected to be spent on each medium
Answer:
$150 billion in total will be spent on both Internet Advertising and TV Advertising.
$0.6 million more will be spent on Internet Advertising than TV.
Let TV Advertising expenses be x.
Expression will be;
x + (x + 600,000) = 150,000,000,000
2x = 150,000,000,000 - 600,000
x = (150,000,000,000 - 600,000) / 2
TV Advertising = $74,999,700,000
Internet Advertising
= TV Advertising + 0.6 million
= 74,999,700,000 + 600,000
= $75,000,300,000

Step-by-step explanation:
In the diagram, △ABC ~ △DEF. What is AC?
The image is of two similar right triangles ABC and DEF with right angles at B and E respectively. First one smaller in size and its base is 3. Base, altitude and hypotenuse of second one are 6, 8 and 10 respectively.
A. 4
B. 7.5
C. 5
D. 3
Answer:5
Step-by-step explanation: If you look at the base of both triangles, you'll notice that the smaller one has a base of 3, and the bigger one has a base of 6. The smaller triangle is half of the big one, therefore we can safely say that the hypothenuse of the smaller triangle is half of that of the larger one. Half of 10 is 5.

Answer:
x= -7/32 or -0.21875
Step-by-step explanation:
You can start by adding like terms such as 10 and 12 to get 22.
Subtract 22 from both sides to get -7=32x.
Divide both sides by 32.
x=-7/32 or -0.21875

Make a conjecture about the sum of primes based on the following pattern:
4 = 2 + 2
6 = 3 + 3
8 = 3 + 5
10 = 3 + 7
12 = 5 + 7
and so on.
The sum of primes is equal to an even number.
The sum of primes is equal to the multiple of the primes.
The sum of primes is equal to primes.
The sum of primes is between 4 and 12.
Answer:
the answer is "the sum of primes is equal to an even number"
Step-by-step explanation:
The sum of primes is equal to an even number. Then option A is correct.
What is a prime number?Any natural number higher than 1 that is not the sum of two smaller natural numbers is referred to be a prime number.
Prime numbers = { 1 , 2 , 3 , 4 , 5 ..............}
The given pattern is,
4 = 2 + 2
6 = 3 + 3
8 = 3 + 5
10 = 3 + 7
12 = 5 + 7
In the given pattern we can see that the sum of all the prime numbers is an even number.
Hence, option A is correct.

A jeweler has 160.5 centimeters of gold chain. He will use half of the chain to make a necklace. He will make 5 bracelets with the remaining chain. If each bracelet is the same length, what will be the length of each bracelet in centimeters?
9514 1404 393
Answer:
16.05 cm
Step-by-step explanation:
Each bracelet will be 1/5 of 1/2 of the chain, so is
(1/5)(1/2) = 1/10
of the original length of the chain.
1/10 × 160.5 cm = 16.05 cm . . . length of each bracelet

jina runs 4 miles in 30 minutes. at the same rate, how many miles would she run in 48 minutes
Answer:
6.4
Step-by-step explanation:
You want to divide 30 by 4 to figure out the rate.
30 / 4 = 7.5
Now you divide again, taking the 48 into the equation.
48 / 7.5 = 6.4
Jina would run 6.4 miles in 48 minutes, following the same rate.

jack has $7.55 of change in his pocket. if he has 4 more dimes than than nickels, and twice as many quarters as nickels, how many of each coin does jack have
Answer:
11 nickels, 15 dimes, 22 quarters
Step-by-step explanation:
number of nickels = x
number of dimes = x+4
number of quarters = 2x
- - - - - -
total of nickels = 5x cents
total of dimes = 10x + 40 cents
total of quarters = 50x cents
- - - - - -
755 = 5x + 10x + 40 + 50x
755 = 65x + 40
715 = 65x
x = 11
x+4 = 15
2x = 22
2(6)-8=10-5
how would 2(6)-8 equal 10-5?!
Answer:
It would not
Step-by-step explanation:
10-5 is basically 2-1 so if 2x6-8 (or 2(6)-8) equals 2-1 then it would. So you start with multiplying 6 and 2 and get 12. 12-8 equals to 4-3. I didn't find your answer but I did what I could.
