Answer:

-x

Step-by-step explanation:

Simplifying

5x + 2 = 3x

Reorder the terms:

2 + 5x = 3x

Solving

2 + 5x = 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

2 + 5x + -3x = 3x + -3x

Combine like terms: 5x + -3x = 2x

2 + 2x = 3x + -3x

Combine like terms: 3x + -3x = 0

2 + 2x = 0

Add '-2' to each side of the equation.

2 + -2 + 2x = 0 + -2

Combine like terms: 2 + -2 = 0

0 + 2x = 0 + -2

2x = 0 + -2

Combine like terms: 0 + -2 = -2

2x = -2

Divide each side by '2'.

x = -1

Simplifying

x = -1

= -x

Answer:

Step-by-step explanation:

Step one:

given data

diameter of circle= 12 in

the radius is r=d/2=6in

the area of the circle is

A=πr^2

A=3.142*6^2

A=3.142*36

A=113.1in^2

If the circle is folded in half, the area will be A/2= 113.1/2= 56.55in^2

In the corresponding shape is folded again the area is A/4= 28.3in^2

The expression for the last shape is

A= πr^2/4

Answer:

DE = 15, AB = 6

Step-by-step explanation:

Because the triangles are similar, that means that the sides are proportional to each other. The ratio of CE to AC is 24/8 which is 3. That means that each length of the small triangle is 3 times smaller than the same side on the larger triangle.

Answer:

Step-by-step explanation:

Given

point (3,-7)

m = 5

Solution

y - y1 = m(x - x1)

y - (-7) = 5(x - 3)

y + 7 = 5x - 15

y = 5x - 15-7

y = 5x-22

Answer

The equation in point-slope form that passes through the point (3,-7)and has a slope of 5 is line Y=5x-22

Answer:

n5 + 17

Step-by-step explanation:

They're asking for a pattern.

17 + 5 = 22

22 + 5 = 27

27 + 5 = 32

So it starts at 17 and increases by five each time.

The nth term increases by 5 each time and starts at 17. That means the nth term is multiplied by 5 each time, but you have to add 17 because that's where the pattern starts.

n5 + 17

Answer:

98.4n

Step-by-step explanation:

12 x 8.2 = 98.4

we need to multiply 98.4 by n, BUT we do not know what n is so we put the variable n next to 98.4 (as a symbol of multiplying 98.4 by n)

Answer:

Yes

Step-by-step explanation:

Let's say each letter was a different number. When it comes to multiplication the order doesn't matter, plus the numbers that are together are just number multiplied.

Example:

(1)(2)(3)*(4)(10)Equals 240

If you switch those around, no matter what it will equal 240

Answer: They are equivalent

Both expressions have one copy of v, w, x, y, and z in some order all being multiplied. We can multiply any two numbers in any order we want

a*b = b*a

For example,

2*3 = 3*2

Since both equal 6.

We can extend this idea out to more than two things being multiplied and the order still doesn't matter. This idea is the commutative property of multiplication.

Answer:

x=0

Step-by-step explanation:

8(4x-4)=-5x-32

32x-32=-5x-32

37x=0

x=0

Answer:

15x, 19x, 26x, and 3x

Step-by-step explanation:

To figure this out, we just need to figure out which sort of value can be combined. Every choice except 49 has a variable attached. The different variables are a, y, x, h, and g. There is only one of each variable except for x. So, you would combine each like term with x as an variable.

Answer:

z = 77

Step-by-step explanation:

Given

[tex]\frac{z}{7}[/tex] - 9 = 2 ( add 9 to both sides )

[tex]\frac{z}{7}[/tex] = 11 ( multiply both sides by 7 to clear the fraction )

z = 77

Since the box represents a proportional relationship, the empty box would be = 22.

When proportional relationship exists between two variables, it means that a particular value would be times with one variable to give the next compared variable.

For example, using the figures given above;

8 pages of notes = 16hours

1 page = 16/8 = 2 hours

Therefore, each page should be times by two to give the number of hours.

Answer: Should it be 68 or 94

Step-by-step explanation:

Answer:

f'(x) = 18x² - 18x + 12

Step-by-step explanation:

Differentiate using the power rule

[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex]

Given

f(x) = (3x² + 6)(2x - 3) ← expand factors using FOIL

     = 6x³ - 9x²  + 12x - 18 , then

f'(x) = 3.6x² - 2.9x + 12

      = 18x² - 18x + 12
