What is the rate of change between (6,12) and (8,20)

Mathematics
1 answer:
Irina-Kira [14]3 years ago
6 0

Step-by-step explanation:

It might be easier thinking of "rate of change" as the slope. Since you'll be finding a slope, then, use the formula m=\frac{y_2-y_1}{x_2-x_1} and substitute the values.

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{20-12}{8-6}\\m=\frac{8}{2} \\m=4

Answer:

m=\frac{4}{1} or m=4

Write the name of the period that has the digits 913.
sergejj [24]

The name of period that has the digits 913 is hundreds.<span>
Because Period is considered to a group of places of the digits.</span>

In this case, the given number is 913 and it is the group of hundred because 900 is the highest number it contains.

We can also write 913 as 

913 = 900 + 10 + 3

It means,

<span>9 hundreds + 10 tens + 3 ones</span>

Solve by substitution 3x+y=3 and 7x+2y=1
balu736 [363]

3x + y = 3

7x + 2y = 1

First isolate one of the variables (x or y) in one of the equations.

Isolate "y" in the first equation(because it is the easiest to isolate) and substitute it into the second equation.

3x + y = 3      Subtract 3x on both sides

3x - 3x + y = 3 - 3x

y = 3 - 3x


7x + 2y = 1

7x + 2(3 - 3x) = 1     [since y = 3 - 3x, you can substitute (3-3x) for "y"]

Multiply/distribute 2 into (3 - 3x)

7x + (3(2) - 3x(2)) = 1

7x + 6 - 6x = 1

x + 6 = 1     Subtract 6 on both sides

x = -5


Now that you know "x", substitute it into one of the equations (I will do both)

3x + y = 3

3(-5) + y = 3       [since x = -5, you can plug in -5 for "x"]

-15 + y = 3    Add 15 on both sides

y = 18


7x + 2y = 1

7(-5) + 2y = 1

-35 + 2y = 1     Add 35 on both sides

2y = 36     Divide 2 on both sides

y = 18


x = -5, y = 18  or  (-5, 18)

Complete the sentence.
Over [174]

Answer:


Step-by-step explanation:

The horizontal asymtote is when there are no solutions for x, so it is when y = -10.

This is because when y = -10, 0.8^x must be 0, but this is impossible. You can test this by trying 4^x/5^x. It will get super small, but never 0.
