Given the function f(x) = -0.5|2x + 2| + 1, for what<br> values of x is f(x) = 6?
Licemer1 [7]

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

Write a function rule for the volume of the cylinder shown at the right with a height 3 in more than 4 times the radius of the c
Ludmilka [50]

we know that

The volume of a cylinder is equal to

V=\pi r^{2} h

where

r is the radius  of the base

h is the height of the cylinder

In this problem

h=3+4r

For r=2\ in

<u>Find the value of h</u>

h=3+4*2

h=11\ in

<u>Find the volume of the cylinder</u>

V=\pi*2^{2}*11

V=44*\pi\ in^{3}= 138.2\ in^{3}

therefore

<u>the answer is</u>

The volume of a cylinder is equal to 138.2\ in^{3}

1/2 (y-3)= 1/2 + (x-3)<br><br> Rapidoo
netineya [11]
Because there are two variables in this equation, you cannot solve for answers. However, I'll assume that you want to get this into slope intercept form as that is the most common way to graph these. The answer in that case is y = 2x - 2

<span>1/2 (y-3)= 1/2 + (x-3) ---> Start by multiplying both sides by 2
(y - 3) = 1 + 2x - 6 ---> now add 3 to each side
y = 3 + 1 + 2x - 6 ----> now simplify like terms. 
y = 2x - 2 </span>

Find the unknown angles
Shtirlitz [24]

Answer:

Step-by-step explanation:

∠WZA + WZY = 180     {linear pair}

88 + ∠WZY = 180

∠WZY = 180 - 88

∠WZY = 92°

∠WXY + ∠WZY = 180     {Opposite angle in cyclic quadrilateral}

x + 92 = 180

       x = 180 - 92

x = 88°
