This is a linear equation in x.

So you need to group like terms

1 + 4x =  - 5 + 7x
Let us group the x terms on the Right Hand Side of the equation and the constant terms on the Left Hand Side.

1 + 5 = 7x - 4x
We can now simplify

6 = 3x
Now let us divide both sides by 3.

\frac{6}{3}  =  \frac{3x}{3}

This implies that

2 = x
or

x = 2
Let us our answer

1 + 4(2) =  - 5  + 7(2)

1 + 8 =  - 5 + 14
9 = 9
Good we are right

Subtract 4x by 7x then you will get 3x

Add 5 to 1 which will be 6

Divide 3x by 3 to get x

Divide 6 by 3 to get 2

X=2

Find the approximate solution(s) to each of the following equations graphically. Use technology to support your
ser-zykov [4K]

Answer: x" = 5.69

Step-by-step explanation:

The graphic solution is attached.

Verifying the solution:

Existence condition: x > 0

2x - 4 = √x + 5

√x =2x - 4 - 5

√x =2x - 9 (²)

x = (2x - 9)²

x = 4x² - 36x + 81

4x² - 36x - x + 81 = 0

4x² - 37x + 81 = 0

Δ = -37² - 4.4.81 = 1369 - 1296 = 73

x = 37 ±√73/8                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          

x' = 3.55

x" = 5.69

checking:

2*3.55 - 4 = 3.1

√3.55 + 5 = 6.88 Its not the same ∴ 3.55 is not a solution

2*5.69 - 4 = 7.39

√5.69 + 5 = 7.39 ∴ it's the only solution

A bicyclist travels 32 kilometers for 2 hours and then and 13 kilometers for the next hour. Calculate the average speed.
GarryVolchara [31]

Answer:

15 km/h

Step-by-step explanation:

To find the speed, divide the total number of kilometers by the total number of hours:

Find the total number of hours:

32 + 13

= 45

Divide this by 3:

45/3

= 15

So, the average speed was 15 km/h
