$6.\\-6(a-7)=(-6)(a)+(-6)(-7)=-6a+42\\\\distributive\ property:\ a(b\pm c)=ab\pm ac$

$7.\\The \formula of\ slope:\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

$We\ have:\\\\(3;\ 4);\ (-6;\ 10)\\\\m=\dfrac{10-4}{-6-3}=\dfrac{6}{-9}=-\dfrac{2}{3}$

$Answer:\ m=-\dfrac{2}{3}$

(25 POINTS) 10. Find the sum of the arithmetic sequence. 5, 7, 9, 11, ..., 23

Taya2010 [7]

Answer:

Sum = 140

Step-by-step explanation:

We find all the terms, we know that every consecutive term, we add 2 until we reach 23:

Sum = 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23

Sum = 140

Graph the function <br> y=4(2^x+3)-1<br> and <br> y=-2(3^x-4)+1

kondaur [170]

The graphs of the functions y = 4(2ˣ + 3) - 1 and y = - 2(3ˣ - 4) + 1 are plotted on the graph.

<h3>What is function?</h3>

A function is a relation between a dependent and a independent variable, such that the dependent variable depends upon the independent one for its existence.

Given are the following functions -

y = 4(2ˣ + 3) - 1

y = - 2(3ˣ - 4) + 1

We have the following functions -

y = 4(2ˣ + 3) - 1

y = - 2(3ˣ - 4) + 1

Refer to the graph attached. The graph of red color represents the function y = 4(2ˣ + 3) - 1 and the graph of blue color represents the function y = - 2(3ˣ - 4) + 1. It can be seen that the graphs are symmetrical about the line y = 10.

Therefore, the graphs of the functions y = 4(2ˣ + 3) - 1 and y = - 2(3ˣ - 4) + 1 are plotted on the graph.

Solve each system of equation using any method.<br> 7 x + y = 5 2x - y = 4

nexus9112 [7]

Answer:

x = 1

y= -2

Step-by-step explanation:

to solve this system of equation , simultaneously using the substitution method

we say let

7 x + y = 5 ............................................. equation 1

2x - y = 4 ................................................... equation 2

from equation 2

2x - y = 4 ................................................... equation 2

2x - 4 = y

y = 2x -4.......................................................... equation 3

put the value of the y = 2x -4 into equation 1

7 x + y = 5 ............................................. equation 1

7x + 2x - 4 = 5

9x-4 = 5

9x = 5 + 4

9x = 9

divide both sides by the coefficient of x which is 9

9x/9 = 9/9

x = 1

substitute the value of x = 1 into equation 3

y = 2x -4.......................................................... equation 3

y = 2(1) -4

y = 2 - 4

y = -2

to check if you are correct put the value of x and y into any of the equations and you will see that the left hand side will be equal to the right hand side.

2x - y = 4 ................................................... equation 2

2(1) -(-2) = 4

2 + 2 = 4

4=4................................... proved
