Please solve this for me!
tatuchka [14]

Step-by-step explanation:

To find the slope between two given points you use the equation:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

(8,10) are (x_{1},y_{1})

(16,24) are (x_{2},y_{2})

After that you just plug in:

m=\frac{24-10}{16-8}

m=\frac{14}{8}

Simplify:

<h2><u><em></em></u>m= \frac{7}{4}<u><em></em></u></h2>

Answer:

The slope is \frac{7}{4} for #1

The first difference of a sequence is 1, 4, 7, 10, 13…
Rama09 [41]

Answer:

1) {4, 5, 9, 16, 26, 39}

2) {3, 4, 8, 15, 25, 38}

3) {3, 4, 8, 15, 25, 38}

Step-by-step explanation:

Hi!

Let's call the sequence {x₁, x₂, x₃, etc}

The information you have is the difference between to consecutive terms:

x_2-x_1= 1\\x_3-x_2= 4\\x_4-x_3= 7\\x_4-x_5= 10\\x_6-x_5= 13

1) Data: x₁=4, then to get x₂ you sum 1, and get x₂=5. Then to get x₃ you sum 4, and get x₃=9, and so on. Result:  {4, 5, 9, 16, 26, 39}

2) Data: x₁ + x₂ = 7. You know that x₂ = x₁ + 1. Then:

x_1+x_2 = x_1 +x_1 +1= 2x_1+1=7\\x_1=3\\x_2= x_1 +1 = 3+1=4

If you continue the same process as in 1), you get {3, 4, 8, 15, 25, 38}

3) Data: x₅ = 25. If you look at the result in 2), you see that x₅ = 25 there!

So the sequence in this case is the same as before {3, 4, 8, 15, 25, 38}
