Please can you answer my question

Answer: The answer to the question you asked up top would be -27, however the question in the picture doesn't match. As for the question in the picture, the answer is should be choice B or  4 square root 2i

Step-by-step explanation:

The first one: add the number together since they are both negative and just place a negative sign in front.

The second one: break down the square root of -18 into 9*-2. Then add   [tex]\sqrt{-2} + 3 \sqrt{-2}[/tex]  which equals [tex]4\sqrt{2}i[/tex]

Answer:

x = -3: [tex]y = 10[/tex], x = -2: [tex]y = 4[/tex], x = -1: [tex]y = 0[/tex], x = 0: [tex]y = -2[/tex], x = 1: [tex]y = -2[/tex], x = 2: [tex]y = 0[/tex], x = 3: [tex]y = 4[/tex]

Step-by-step explanation:

Let [tex]y = x^{2}-x-2[/tex], where [tex]x[/tex] and [tex]y[/tex] are the independent and dependent variables, respectively. The approach consists in evaluating the function at values presented in statement:

x = -3

[tex]y = (-3)^{2}-(-3)-2[/tex]

[tex]y = 10[/tex]

x = -2

[tex]y = (-2)^{2}-(-2)-2[/tex]

[tex]y = 4[/tex]

x = -1

[tex]y = (-1)^{2}-(-1)-2[/tex]

[tex]y = 0[/tex]

x = 0

[tex]y = (0)^{2}-(0)-2[/tex]

[tex]y = -2[/tex]

x = 1

[tex]y = (1)^{2}-(1)-2[/tex]

[tex]y = -2[/tex]

x = 2

[tex]y = (2)^{2}-(2)-2[/tex]

[tex]y = 0[/tex]

x = 3

[tex]y = (3)^{2}-(3)-2[/tex]

[tex]y = 4[/tex]

Answer:

Choice A.

Step-by-step explanation:

Since this is a right triangle, we can use Pythagorean Theorem to solve for the missing side length.

3² + x² = 8²

9 + x² = 64

x² = 55

x = √55

Therefore, the answer is choice A.

m<B=72 degrees

m<C= 36 degrees

Step-by-step explanation:

m<B is congruent to m<A

72 times 2 equals 144

180 minus 144 equals 36

Answer:

Simplifying 6p + 2(4 + -2p) = 3(p + 4) 6p + (4 * 2 + -2p * 2) = 3(p + 4) 6p + (8 + -4p) = 3(p + 4) ... Move all terms containing p to the left, all other terms to the right. ... When you enter an equation into the calculator, the calculator will begin by ... Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5).

==========================================

Explanation:

1/2 = 0.5

Every 60 days, the amount cuts in half.

We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.

After another 60 days, we have 452*0.5 = 226 grams left over.

-------------

Alternative Method:

We can apply the half-life formula.

y = a*(0.5)^(x/H)

where,

In this case,

When x = 120 days go by, we have....

y = a*(0.5)^(x/H)

y = 904*(0.5)^(x/60)

y = 904*(0.5)^(120/60)

y = 904*(0.5)^(2)

y = 904*(0.25)

y = 226 grams of antimony left over.

This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.

Answer:

  (6, 12)

Step-by-step explanation:

The center of the circle is the midpoint of the diameter, the average of the end point coordinates:

  ((3, 8) +(9, 16))/2 = (3+9, 8+16)/2 = (12, 24)/2 = (6, 12)

The center of the circle is (6, 12).

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of 2 pencils be = A

Now , the equation will be

The cost of 6 pencils is = 36 cents

So ,

The cost of one pencil is = cost of 6 pencils / 6

The cost of one pencil is = 36 / 6

The cost of one pencil is = 6 cents

And , the cost of 2 pencils is calculated by the equation

The cost of two pencils is A = cost of one pencil x 2

The cost of two pencils is A = 6 x 2

The cost of two pencils is A = 12 cents

Therefore , the value of A is 12 cents

Hence , The cost of 2 pencils is 12 cents
