Given the function f(x) = -0.5|2x + 2| + 1, for what values of x is f(x) = 6?

Mathematics

Licemer1 [7]3 years ago

Answer:

<em>No values of x can make f(x)=6</em>

Step-by-step explanation:

Equation with Absolute Value

The absolute value of a number is always positive. That condition must be met when solving equations. Any condition that goes against the rule, must be discarded and not part of the solution.

The function provided in the question is:

f(x) = -0.5|2x + 2| + 1

We need to find the value(s) of x that make:

f(x)=6

It needs to solve the equation:

-0.5|2x + 2| + 1=6

Subtracting 1:

-0.5|2x + 2| =6-1=5

Dividing by -0.5:

|2x + 2| =5/(-0.5)=-10

We reach to this equation to solve:

|2x + 2| =-10

As stated above, the absolute value is always positive, and the equation forces the absolute value to be negative. There is no possible value of x that makes the absolute value negative, thus:

No values of x can make f(x)=6

Simplify square root of ten times square root of eight.
Romashka-Z-Leto [24]
<h2>Explanation:</h2><h2></h2>

Here we need to simplify the square root of ten times square root of eight, so let's write this step by step:

Step 1. The square root of ten

\sqrt{10}

Step 2. The  square root of eight

\sqrt{8}

Step 3. The square root of ten times square root of eight

\sqrt{10}\times \sqrt{8} \\ \\ \\ \text{From radical property:} \\ \\ \sqrt{a}\times \sqrt{b}=\sqrt{ab} \\ \\ \\ So: \\ \\ \sqrt{10}\times \sqrt{8}=\sqrt{80} \\ \\ \\ But: \\ \\ \sqrt{80}=\sqrt{16\time5}=\sqrt{16}\sqrt{5}=4\sqrt{5}

Finally, the correct option is:

<em>Four square root of five</em>

Questions<br> E<br> Given EA = 8 and AT = 10<br> Find ET
xxTIMURxx [149]

Answer:

ET = 80/A^2

Step-by-step explanation:

First, isolate the variables that you need, which is E and T, using the two equations you were given.

EA = 8

E = 8/A (divide A on both sides to isolate E)

AT = 10

T = 10/A (divide A on both sides to isolate T)

Now, substitute.

ET --> (8/A) x (10/A) = 80/A^2

Minor arc KL measures 135°. Circle O is shown. Line segments K O and O L are radii. Which is the radian measure of central angle
snow_lady [41]

StartFraction 3 pi Over 4 EndFraction radians

Step-by-step explanation:

Pi radians is equal to 180°

Given the minor arc angles as 135°, change this value to pi radians

180° =π radians

135° = ?

Cross multiply

135° * π radians / 180°

=135/180 *  π radians

=3 π/4  radians
