Consider the following pair of equations:

Mathematics
1 answer:
Bond [772]3 years ago
6 0
So the equations are: 

y= 3x + 3

y= x- 1

By the transitive property, we know x-1= 3x+3 (Transitive property means if a= b, and b= c, shouldn't a = c if they both equal b?)

so, x- 1= 3x + 3.  Now we isolate x and solve:
        +1          +1
x= 3x+ 4
-x  -x

0 = 2x+ 4
-4        -4

-4 = 2x
/2    /2

x= -2

Now, you can plug that back in to find y:

y = x- 1
y= -2 -1
y= -3

Then plug them both in to make sure it is correct. :o)

Write an equation in point slope form of the line passes through the point (9,0) and has a slope of m=-3
Brut [27]

Answer:

\huge y =  - 3(x - 9)

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

From the question we have the final answer as

y - 0 =  - 3(x - 9)  \\  \\ \\ y =  - 3(x - 9)

Hope this helps you

Click here What is the average rate of change for this exponential function for the interval from x=2 to x = 4? 15 10 -5 5 10 O
Triss [41]

Answer:

c. 6

Step-by-step explanation:

Given

See attachment for graph

Required

Average rate of change

This is calculated as:

Rate = \frac{f(b) - f(a)}{b - a}

Where

(a,b) = (2,4)

So, we have:

Rate = \frac{f(4) - f(2)}{4 - 2}

Rate = \frac{f(4) - f(2)}{2}

Using the attached graph, we have:

f(2) = 4

f(4) = 16

So, we have:

Rate = \frac{16- 4}{2}

Rate = \frac{12}{2}

Rate = 6
