Answer:

(4,18)

Step-by-step explanation:

We can just pluck the x values into the equation: y = 5x -1 to see if the y values fit.

1. y = 5(4) - 1

= 20 - 1

= 19 (Nope, 18 is not 19)

2. y = 5(3) - 1

= 15 - 1

= 14 (Yep, same as option)

3. y = 5(0) - 1

= 0-1

= -1 (Yep, same as option)

4. y = 5(2) - 1

= 10 - 1

= 9 (Yep, same as option)

Answer:

Step-by-step explanation:

I saw karma so i came as fast as I could- welp anyways

Lets test the first equation and coordinate #1 first, 3x-2y=12, and (10,9).

Here we can substitute x as 10 and y as 9, and solve the equation to see if 3(10)-2(9) equals 12 or not.

30-18=12, yep

now lets test the second coordinate, (0, -6). Substitute x as 0 and y as -6, and solve the equation.

3(0)-2(-6)=12

0+12=12, yep

So I definitely works

For II, lets do the same thing

(10, 9) -- 9=3/2*10-6

9=15-6, works

(0, -6) — -6= 3/2*0-6

-6=0-6, also works

So uh therefore I and II both work you see what I mean-

i apologize in advance if i made you more confused than you already are-

Answer:

next term: 15an = n(n+1)/2

Step-by-step explanation:

Each term is the previous term with the current term number added. The 5th term will be 5 + (4th term) = 5 + 10 = 15.

The next term is 15.

_____

The sequence of triangular numbers is given by the explicit formula ...

an = n(n+1)/2

Finding the Formula

The sequence of first differences is ...

3 -1 = 2

6 -3 = 3

10 -6 = 4

And the sequence of second differences is ...

3 -2 = 1

4 -3 = 1

These are constant, indicating the sequence is described by a polynomial function of 2nd degree.

There are several ways to find the coefficients of the quadratic function. One is to solve for them using a system of equations.

n = 1

a1 = 1 = a(1)^2 +b(1) + c

n = 2

a2 = 3 = a(2)^2 + b(2) +c

n = 3

a3 = 6 = a(3)^2 +b(3) +c

To solve, we can subtract each equation from the next:

a2 -a1 = (3) -(1) = a(4 -1) +b(2 -1) +c(1 -1)

2 = 3a +b

and

a3 -a2 = (6) -(3) = a(9 -4) +b(3 -2) +c(1 -1)

3 = 5a +b

Now we can subtract the first of these equation from the second:

(3) -(2) = a(5 -3) +b(1 -1) ⇒ 1 = 2a ⇒ a = 1/2

Then ...

2 = 3(1/2) +b

1/2 = b

1 = a + b + c ⇒ 1 = 1/2 + 1/2 + c ⇒ c = 0

So, the quadratic function describing the sequence of triangular numbers is ...

an = (1/2)(n^2 +n)

an = n(n+1)/2

8. There are 575 students in a school. If the number of girls is 54 more than the boys
how many boys are there in the school ?Find it.

Answers

Step-by-step explanation:

here's your solution

=> total number of student = 575

=> let the number of boys be x

=> then the number of girls = x + 54

=> a/q , x + x + 54 = 575

=>.2x + 54 = 575

=>. 2x = 575 - 54

=> 2x = 521

=> x = 521/2

=> x = 260.5

=> number of girls = 260.5+ 54.

D) 4.1 - 1=y

Answers

9514 1404 393

Answer:

C 3x +1 = y

Step-by-step explanation:

x-values increase by 1 from row to row.

y-values increase by 3 from row to row.

The slope of the linear function is the ratio of the y-increase to the x-increase:

m = ∆y/∆x = 3/1 = 3

The only offered choice with an x-coefficient of 3 is ...

C 3x +1 = y

If you check this against the table entries, you find it fits.

3(1) +1 = 4

3(2) +1 = 7

and so on.
