Can someone answer just this one? Thank you :)

Answer:

2

Step-by-step explanation:

3(x-4)=2(-2x+1)

3x-12=-4x+2

3x-(-4x)-12=2

3x+4x=2+12

7x=14

x=14/7

x=2

Answer:

40 in²

Step-by-step explanation:

There are four triangles for each side of the pyramid, and the height is three inches. The area of a triangle is base times height divided by 2, so each triangle is 6 in².

4(base) x 3(height) ÷ 2 = 6

Multiply 6 by 4 because there are four triangles, which is 24.

Once you have that, the only surface left is the bottom of the pyramid. You can find this by multiplying 4 by 4, since it's a square.

4 x 4 = 16

If you add 16 and 24 together, that's your answer.

Given:

In triangle ABC, [tex]AB=11x-25,DE=4x+1[/tex].

To find:

The measure of DE.

Solution:

From the given figure, it is clear that D is the midpoint of AC and E is the midpoint of BC. So, the line segment DE is the mid-segment of the triangle ABC.

According to the triangle mid-segment theorem, mid-segment of a triangle is equal to half of its base.

Using triangle mid-segment theorem, we get

[tex]DE=\dfrac{1}{2}AB[/tex]

[tex](4x+1)=\dfrac{1}{2}(11x-25)[/tex]

[tex]2(4x+1)=11x-25[/tex]

[tex]8x+2=11x-25[/tex]

Isolate the variable terms.

[tex]8x-11x=-2-25[/tex]

[tex]-3x=-27[/tex]

[tex]x=\dfrac{-27}{-3}[/tex]

[tex]x=9[/tex]

The value of x is 9. So,

[tex]DE=4x+1[/tex]

[tex]DE=4(9)+1[/tex]

[tex]DE=36+1[/tex]

[tex]DE=36+1[/tex]

[tex]DE=37[/tex]

Therefore, the length of DE is 37 units.

Step-by-step explanation:

Answer:

Yes.  2469/2000

Step-by-step explanation:

The true statement about the end behavior of f(x) is (b)

The equation of the function is given as;

f(x) = -4x^6 +6x^2-52

The leading coefficient of the above function is

Leading coefficient = -4

-4 is less than 0 i.e. negative

This means that options (a) and (c) are false

Also;

The ends of even functions face the same direction, and not opposite directions.

Hence, the true statement about the end behavior of f(x) is (b)

Answer:      x=-5

Step-by-step explanation:

Distribute

6(x+3)-1(x+4)=-11

6x+ 18-1(x+4)=-11

6x +18-x-4=-11

Subtract the numbers

6x +18-x-4=-11

6x +14-x=-11

Combine like terms

6x +14-x=-11

5x +14=-11

subtract 14 from both sides of the equation

5x +14=-11

5x +=14-14 = -11 -14

simplify

5x=-25

divide both sides

Step-by-step explanation:

Answer:

x = 6√2

Step-by-step explanation:

This is a right triangle, specifically a 45-45-90 one.  Using the Pythagorean Theorem, we get x^2 + x^2 = (12 cm)^2, or:

2x^2 = 144 cm^2, or

x^2 = 72 cm^2.

This comes out to x = 6√2

Answer:

Nina will be 18 years old when she is half as old as her mother.

Step-by-step explanation:

With the information provided, you can write an equation that indicates that Mrs. Matthews current age plus x which would be the number of years until Nina will be half as old as her mother would be equal to two times nina's age plus x, as you would have to multiply Nina's age at that time for 2 to be equal to her mother's age. The equation would be:

24+x=2(6+x)

Now, you can solve for x:

24+x=12+2x

24-12=2x-x

12=x

Finally, you  have to add the value of x plus Nina's current age to determine her age when she is half as old as her mother:

12+6=18

Acording to this, the answer is that Nina will be 18 years old when she is half as old as her mother.

Answer:

29: 7

Step-by-step explanation:

[tex] \frac{8}{3x - y} = \frac{5}{x + 3y} [/tex]

Cross multiply:

[tex]8(x + 3y) = 5(3x - y)[/tex]

Expand bracket:

[tex]8x + 24y = 15x - 5y[/tex]

Bring x terms to 1 side, y terms to the other:

[tex]15x - 8x = 24y + 5y[/tex]

Simplify:

[tex]7x = 29y[/tex]

Divide by 7 on both sides:

[tex]x = \frac{29}{7} y[/tex]

Divide both sides by y:

[tex] \frac{x}{y} = \frac{29}{7} [/tex]

∴ The ratio of x to y is 29:7.

Answer:

Step-by-step explanation:

If n is the number of bowls, then replace n with 3

Answer:

Commission earned= $43.95

Step-by-step explanation:

Giving the following information:

Commission rate= 15% = 0.15

Sales= $293

To calculate the commission earned by selling the laptop, we need to use the following formula:

Commission earned= commission rate*sales

Commission earned= 0.15*293

Commission earned= $43.95

F ( x + 5 )= x ^2 + 12 x + 29

The composition (gof)(x) of the given functions is (g°f)(x) = x² + 12 x + 29

Function is a type of relation, or rule, that maps one input to specific single output.

For two given functions f(x) and g(x), the composite function

(g ° f)(x) is g(f(x))

we know that:

g(x) = x+5

f(x) = x² + 2x - 6

Then:

(g°f)(x) = g(f(x))

So, we just need to evaluate g(x) in f(x):

g(f(x)) = f(x) + 5 = (x² + 2x - 6) + 5

(g°f)(x) = x² + 12 x + 29

Then the correct answer is (g°f)(x) = x² + 12 x + 29
