How many solutions are there to the equation below?<br> 8x + 47 = 8(x + 5)
qaws [65]

Answer:

there are 0 solutions to the equation

Step-by-step explanation:

To know how many solutions are in the problem, we have to solve for x and see what result we have left. According to the result, we will know how many solutions there are

8x + 47 = 8(x + 5)

8x + 47 = 8*x + 8*5

8x + 47 = 8x + 40

8x - 8x = 40 - 47

0 = -7

As we can see we are left with an equality that is not fulfilled, this means that there is no solution to the problem, at least in the field of real numbers

a 1 ​ =− 3 1 ​ a, start subscript, 1, end subscript, equals, minus, start fraction, 1, divided by, 3, end fraction a i = a i − 1
MrRa [10]

Answer:

S_{75}=-506.888989761$ X 10^{32}

Step-by-step explanation:

Given the sequence

a_1=-\dfrac{1}{3}\\ a_i=a_{i-1}\cdot (-3)

a_2=a_{2-1}\cdot (-3)=a_1 \cdot (-3) = -\dfrac{1}{3}\cdot (-3)=1\\a_3=a_{3-1}\cdot (-3)=a_2 \cdot (-3) = 1 \cdot (-3)=-3\\a_4=a_{4-1}\cdot (-3)=a_3 \cdot (-3) = -3 \cdot (-3)=9\\

Therefore the sequence is:

 -\dfrac{1}{3}, 1, -3, 9, ...

This is a geometric sequence where the:

First Term, a_1=-\dfrac{1}{3}

Common ratio, r =-3

We want to determine the sum of the first 75 terms.

For a geometric sequence, the sum:

S_n=\dfrac{a_1(1-r^n)}{1-r} \\

Therefore:

S_{75}=\dfrac{-\dfrac{1}{3}(1-(-3)^{75})}{1-(-3)} \\\\=\dfrac{-(1-(-3)^{75})}{4*3}\\\\S_{75}=\dfrac{(-3)^{75}-1}{12}\\\\S_{75}=-506.888989761$ X 10^{32}

QUESTION 2 Write the slope-intercept form of the equation of the line through the gran point micia the grea slope through: (5,-2
Lubov Fominskaja [6]

Answer:

y = -x+3

Step-by-step explanation:

Slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -1x +b

Using the point for x and y we can calculate b

-2 = -1(5)+b

-2 = -5+b

Add 5 to each side

-2+5 = b

3 = b

y = -x+3

Evaluate the function rule to find the range of each function for the domain {-3, 0, 5}.
Basile [38]
The range is ur f(x) values and ur domain is ur x values.

f(x) = 4x - 9...when domain (x) is -3
f(-3) = 4(-3) - 9
f(-3) = -12 - 9
f(-3) = - 21

f(x) = 4x - 9...when domain (x) = 0
f(0) = 4(0) - 9
f(0) = -9

f(x) = 4x - 9...when domain (x) is 5
f(5) = 4(5) - 9
f(5) = 20 - 9
f(5) = 11

so ur range is { -21,-9,11} <==
