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.

Answer:

Group 4

Step-by-step explanation:

Group 4 is the only group that has any numbers. And Group 2 the range is not big at all.

Was this the question or did you make a mistake with the numbers?

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

Answer:

y = 90

Step-by-step explanation:

Since, e || f and a || b

Therefore, quadrilateral so formed is a rectangle.

Each angle of a rectangle is right angle.

Answer:

13. -200, balance on car loans

14. 8, monthly payments

15. linear eqn, y=ax+b

16.values of y will decrease.(although i think the graph will remain linear)

17. as the monthly payment decrease so does the balance on car loan decrease.

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.

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.

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.

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

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.

Answer:

It will be 5 seconds before the ball hits the ground  

Step-by-step explanation:

∵ A ball is thrown from the top row of seats in a stadium

∵ The function

∵ h(t) = −16t² + 64t + 80 , gives the height, in feet, of the ball t seconds

   after it is thrown

∵ The ball hits the ground

→ That means h(t) = 0

∵ h(t) = 0

∴ 0 = -16t² + 64t + 80

→ Reverse the two sides

∴ -16t² + 64t + 80 = 0

→ Divide both sides by -16 to simplify it

∵  [tex]\frac{-16t^{2}}{-16}+\frac{64t}{-16}+\frac{80}{-16}=\frac{0}{-16}[/tex]

∴ t² - 4t - 5 = 0

→ Factorize it into two factors

∵ t² = t × t

∵ -5 = -5 ×  1

∵ -5t + 1t = -4t ⇒ the middle term

→ The factors are (t - 5) and (t + 1)

∴ (t - 5)(t + 1) = 0

→ Equate each factor by 0 to find t

∵ t - 5 = 0

→ Add 5 to both sides

∴ t = 5

∵ t + 1 = 0

→ Subtract 1 from both sides

∴ t = -1 ⇒ rejected because no negative value for the time

∵ t = 5

∴ It will be 5 seconds before the ball hits the ground
