What quadrant is the
ordered pair (2,-3) in?

Answer:

[tex]f(3) = \frac{-26}{9}[/tex]

[tex]f(2 + h) = \frac{- 11 - 12h - 12^2}{4 + 4h + h^2}[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \frac{1}{x^2} - 3[/tex]

Required

Find f(3) and f(2 + h)

Solving f(3)

Substitute 3 for x in [tex]f(x) = \frac{1}{x^2} - 3[/tex]

[tex]f(3) = \frac{1}{3^2} - 3[/tex]

[tex]f(3) = \frac{1}{9} - 3[/tex]

Take LCM

[tex]f(3) = \frac{1 - 27}{9}[/tex]

[tex]f(3) = \frac{-26}{9}[/tex]

Solving f(2 + h)

Substitute 2 + h for x in [tex]f(x) = \frac{1}{x^2} - 3[/tex]

[tex]f(2 + h) = \frac{1}{(2 + h)^2} - 3[/tex]

[tex]f(2 + h) = \frac{1}{(2 + h)(2 + h)} - 3[/tex]

[tex]f(2 + h) = \frac{1}{4 + 2h + 2h + h^2} - 3[/tex]

[tex]f(2 + h) = \frac{1}{4 + 4h + h^2} - 3[/tex]

Take LCM

[tex]f(2 + h) = \frac{1- 3(4 + 4h + h^2)}{4 + 4h + h^2}[/tex]

[tex]f(2 + h) = \frac{1- 12 - 12h - 12^2}{4 + 4h + h^2}[/tex]

[tex]f(2 + h) = \frac{- 11 - 12h - 12^2}{4 + 4h + h^2}[/tex]

Answer:

Step-by-step explanation:

No, I don't agree with Daryl. If you multiply -3 by 2, you will get -6. -6 is not equal to -32, which means that they don't have the same value, so Daryl is wrong.

Answer:

The area of the shaded region is 3.

Step-by-step explanation:

Since point E lies halfway between AB and BC, the area of the shaded region (As) consists of two identical triangles with base equal to AB and height equal to half the measure of BC:

[tex]A_s=2 * A_t[/tex]

Where At is the area of each triangle.

[tex]\displaystyle A_t=\frac{AB*BC/2}{2}[/tex]

[tex]\displaystyle A_t=\frac{AB*BC}{4}[/tex]

We know AB=3 and BC=2, thus:

[tex]\displaystyle A_t=\frac{3*2}{4}=\frac{6}{4}[/tex]

Simplifying:

[tex]\displaystyle A_t=\frac{3}{2}[/tex]

Finally:

[tex]\displaystyle A_s=2 * \frac{3}{2}[/tex]

[tex]A_s=3[/tex]

The area of the shaded region is 3.

Note the area of the shaded region is half the area of the rectangle.

[tex]5x - 60 > 8x[/tex]

[tex]8x < 5x - 60[/tex]

Subtract sides 5x

[tex] - 5x + 8x < - 5x + 5x - 60[/tex]

[tex]3x < - 60[/tex]

Subtract sides 3

[tex] \frac{3x}{3} < \frac{ - 60}{3} \\ [/tex]

[tex]x < - 20[/tex]

Answer: The answer is x<–20.

Step-by-step explanation: Let’s solve the inequality step by step.

• Step 1 Subtract 8x from both sides. Do the rest of the step by step of the following inequality.

Answer:

X-(-5) = 10

x+5=10

x=10-5

x=5

X-(-5) = 10

-negative sign and -negative sign= +positive sign

X+5=10

move +5 to other side to get X by itself

sign changes from +5 to -5

X+5-5=10-5

X=10-5

X=5

answer: X=5

Answer:

since your in pre-k bud x+y+z = abc :)

Step-by-step explanation:the alphabet ends in xyz so it only makes sense for the answer to be abc

this is totally correct:)

Answer:

g(x) = √(2x)

Step-by-step explanation:

f(x) = 3x^2

g(f(x)) =√6x

g(3x^2) = x√6

g(x) must be √(2x)

because if we  substitute  x = 3x^2 in this we get

(√2(3x^2))

= √2√3√(x^2)

= √6 x

Answer:

x = 120

Step-by-step explanation:

Let's draw an imaginary dot in the middle of that line which runs between those two parallel lines, and now lets look at it as an angle.

This lines' angle is 180 degrees. Now lets move those two parallel lines together on the imaginary dot in the middle.

We can see that on the left side is one degree and the other side is another, however when we put them together we get the angle measurement of the our line which we identified was 180.

Now that we can see that our two angles must equal 180 when put together we know and can say that:

40 + (x + 20) = 180

So, lets work this out like basic algebra now.

40 + x + 20 = 180

       x + 60 = 180

           - 60   - 60

               x = 120

And voila we have our x value.

Hope this helps :)

Step-by-step explanation:

Answer:

-1 5/8

Step-by-step explanation:

Let the total amount in the bowl be x;

If on Day 1, the volume of water in the bowl decreases by 7/8 cup, the remaining water will be;

x - 7/8

If on day 2, the volume in the bowl decreases by 3/4 cup, the remaining volume of water after the second day will be;

= x - 7/8 - 3/4

= x - (7-2(3))/8

= x - (7+6)/8

= x - 13/8

This shows that the total change after the two days is -13/8

As a mixed fraction;

-13/8 = -1 5/8

Answer:

1260.04

Step-by-step explanation:

The formula for compound interest is:

A = P(1+[tex]\frac{r}{n}[/tex][tex])^{nt}[/tex] where A is the final amount, P is the initial principal balance, r is the interest rate, n is the number of times interest applied per time period and t is the number of time periods elapsed. Since the deposit was compounded annually, just like the interest, we can omit the n in the equation.

Applying the formula to question:

800(1+[tex]\frac{2.88}{100}[/tex][tex])^{16}[/tex] = 1260.04 (rounded off to nearest cent since it's money)

Answer:

Using distributive property to remove the parentheses [tex](x+12)8[/tex] we get [tex]8x+96[/tex]

Step-by-step explanation:

We need to use distributive property to remove the parentheses (x+12)8

According to distributive property of multiplication over addition:

[tex]a(b+c)=ab+ac[/tex]

Now, using the above distributive property to solve the given question. Multiply 8 with terms inside the bracket and solving:

[tex](x+12)8\\=8x+8*12\\=8x+96[/tex]

So, using distributive property to remove the parentheses [tex](x+12)8[/tex] we get [tex]8x+96[/tex]

Answer:

Yes, it is possible. We already know that complex roots exist in conjugate pair but the case is true only when the equation has real coefficients. But on the other hand, if the equation has complex coefficients, then it is possible to attain one real and one complex root.

Answer:

No,
