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

-3 is a solution of y &gt; -2<br> true or false
BartSMP [9]
That is false.  When you look at a number line, -3 is to the left of -2.  A number to the left of another number is less than the number to the right.

DIVIDE. (4x4 - 8x3 + 4x - 8) / (4x - 8)
svetoff [14.1K]

Answer:

x³+1

Step-by-step explanation:

4x-8 | 4x⁴ - 8x³ + 4x - 8

       <u>_4x⁴ - 8x³______</u> <-- x³

                           4x - 8

      <u>                     4x - 8</u> <-- 1

                                  0 | x³+1

Therefore, (4x⁴-8x³+4x-8)/(4x-8) = x³+1
