Answer:

C. x - 5= -3

Step-by-step explanation:

Step 1: |x - 5| +2-2 =5-2

Step 2: |x - 5| = 5-2

Step 3: |x - 5| = 3

Step 4: x - 5 = -3

Step 5: x - 5+5 = -3+5

x = 2

Ket [755]

The percent error is 4.167 %

Solution:

Given that, Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour

When checking the accuracy of her speedometer, an Automotive Specialist recorded her speed at 50 miles per hour

The percent error is given by formula:

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

$\text{Percent error } = \frac{\text{experimental-theoretical}}{theoretical} \times 100$

From given,

Experimental value = 50

Theoretical value = 48

Substituting the values in formula, we get,

$Percent\ Error = \frac{50-48}{48} \times 100\\\\Percent\ Error = \frac{2}{48} \times 100\\\\Percent\ Error = 4.167$

Thus the percent error is 4.167 %

Answer:

see the explanation

Step-by-step explanation:

The complete question is

The first three steps of completing the square to solve the quadratic equation x2 +4x -6= 0, are shown below.

Step 1: x2 +4x= 6

Step 2: x2 +4x+4=6+4

Step 3: (x +2)^2=10

What are the next 3 steps?

we have

step 4

Take square root both sides

$\sqrt{(x+2)^2} =\sqrt{10}$

step 5

Simplify

$x+2=\pm\sqrt{10}$

step 6

Solve for x

subtract 2 both sides

$x=-2\pm\sqrt{10}$

$x_1=-2+\sqrt{10}$

$x_2=-2-\sqrt{10}$
