I'm assuming you mean #10?

So we're given this equation:

b - 5 = - 5

In this equation, we a variable of <em>b</em>. We want to solve for <em>b</em> by isolating it, or setting it alone. We see that on the side with <em>b</em> on it, it is being subtracted by 5. We want to the opposite in order to isolate <em>b</em>.

Remember that when you do one thing to one side of the equation, you must do it to the other side as well. We can add 5 on both sides to cancel out the negative 5 on the left.

b - 5 = -5&#10;&#10;add 5 on both sides&#10;&#10;b - 5 + 5 = -5 + 5&#10;&#10;simplify&#10;&#10;b = 0

Therefore we know that <em>b</em> does not equal -10, which can be represented as:

b  \neq  -10

So you have to (a) color the hair yellow.

So the answer is (a). Because -10 - 5 = -15. So it's obviously not the letter (b), since your answer in this equation is supposed to be -5. The correct equation is : 0 - 5= -5. To find this answer you must do the equation that is contrary to the subtraction which is the addition. So, -5 +5 = 0.

Hope this helps you! :)

A water cup is shaped like a cone. It has a diameter of 3 inches and a slant height of 5 inches. About how many square inches of
drek231 [11]
So basically, what this question is asking you for is the surface area of the entire cone.
To find it, we can use the formula:
SA = 3.14*r*l+3.14*r^2, where r is radius and l is lateral height
Now, all we have to do is plug all of the given values into the equation

Therefore, the equation we get is:
SA = 3.14*1.5*5 + 3.14*1.5^2
If we simplify, we find that the surface area is equal to 30.615
If we round this number to the nearest whole number, we get 31 square inches

Therefore the answer is 31

Hope this helped!! :D

If f(x) is a third degree polynomial function and g(x) = f(–2x), which of the following is NOT true?
valina [46]

Answer:

f(x) and g(x) have the same x-intercepts (is <em>not true</em>)

Step-by-step explanation:

g(x) is a reflection across the y-axis and a horizontal compression of f(x). In general those transformations will move the x-intercepts. (The y-intercept and the number of x-intercepts will remain unchanged.)

_____

<em>Comment on the question/answer</em>

f(x) = x^3 is a 3rd degree polynomial. When transformed to g(x) = -8x^2, its only x-intercept (x=0) remains the same. The answer above will not apply in any instance where the only x-intercept is on the line of reflection. (The question is flawed in that it does not make any exception for such functions.)

Which of the following inverse functions are defined for x=-1/2? Select all that apply.
Aleksandr-060686 [28]

Answer:

A, B, E, and F  

Step-by-step explanation:

sinx and cosx are defined for all values of x. So, sin⁻¹x and cos⁻¹x  are also defined for all values of x.  

A and E are correct.

tanx is defined for all values of x.

However, tan(nπ) = 0 at when n is an integer. So, tan⁻¹(±nx) is undefined. However, tan⁻¹(-½x) is defined, because -½ is not an integer.

B and F are correct.

C and D are <em>wrong</em>. Both sec⁻¹x  and csc⁻¹x are undefined when -1 < x < 1, and -½ is in this forbidden region.
