Answer:

Making it the answer A

Step-by-step explanation:

The correct option that shows the values of the two 3s in the price $3,435 is D) 3,000; 30

In the given price, $3,435, the first 3 represent the thousand place value, while the second 3 represents the one's place value.

The comma in option D indicates the separation of thousands, so it correctly represents the first 3 as part of the thousands place value.

The number 30 in option D represents the second 3 as part of the one's place value.

Therefore, option D) 3,000; 30 is the choice that correctly shows the values of the two 3s in the price $3,435.

Answer: 2x^2-y^2+5xy-2y

a. There is four terms in the simplified expression.

b. Two terms in the simplified expression are negative.

Step-by-step explanation:

Write the expression like an addition/ subtraction problem.

-3x²+2y²+5xy-2y

+5x²-3y²

_________

This makes it easier to identify what to combine for like terms.

Final answer:

The simplified expression is 2x² - y² + 5xy - 2y. There are two negative terms in the simplified expression: -y² and -2y.

Explanation:

To simplify the expression -3x² + 2y² + 5xy - 2y + 5x² - 3y², we need to combine like terms. The like terms are the ones that contain the same variables to the same power. Here’s a step-by-step explanation:

The simplified expression is 2x² - y² + 5xy - 2y.

Now, to answer the question about the number of negative terms: in the simplified expression, there are two negative terms, which are -y² and -2y. A term is considered negative if it has a minus sign in front of it, indicating that it is less than zero when all other variables are considered to be positive.

Answer:

Hundreds

Step-by-step explanation:

The value of 5 is given based on the place value in which it is located.

The 5 is located in the "hundreds" place value, and so Hundreds is your answer.

3: Thousands

5: Hundreds

9: Tens

0: Ones

For this case we have the expression:

"the square root of 4" is represented algebraically as:

Answer:

2y + 3x = 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 2y = - 4 into this form

Subtract 3x from both sides

2y = - 3x - 4 ( divide all terms by 2 )

y = - [tex]\frac{3}{2}[/tex] x - 2 ← in slope- intercept form

with slope m = - [tex]\frac{3}{2}[/tex]

• Parallel lines have equal slopes, thus

y = - [tex]\frac{3}{2}[/tex] x + c ← partial equation of parallel line

To find c substitute (4, - 1) into the partial equation

- 1 = - 6 + c ⇒ c = - 1 + 6 = 5

y = - [tex]\frac{3}{2}[/tex] x + 5 ← in slope- intercept form

Multiply through by 2

2y = - 3x + 10 ( add 3x to both sides )

3x + 2y = 10 ← in standard form

The equation of the line parallel to 3x+2y= -4 goes through the point (4,-1).

The general equation of a straight line exists y = mx + c, where m is the gradient, and y = c exists the value where the line cuts the y-axis. This number c is named the intercept on the y-axis. The equation of a straight line with gradient m and intercept c on the y-axis stands y = mx + c.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 2y = - 4 into this form

Subtract 3x from both sides

2y = - 3x - 4 ( divide all terms by 2 )

y = -  x - 2 ← in slope- intercept form

with slope m = -

• Parallel lines have equal slopes, thus

y = -  x + c ← partial equation of parallel line

To find c substitute (4, - 1) into the partial equation

- 1 = - 6 + c ⇒ c = - 1 + 6 = 5

y = -  x + 5 ← in slope- intercept form

Multiply through by 2

2y = - 3x + 10 ( add 3x to both sides )

3x + 2y = 10 ← in standard form.

ANSWER

[tex]x = - 3[/tex]

EXPLANATION

When a quadratic equation is in the vertex form,

[tex]f(x) = a {(x - h)}^{2} + k[/tex]

the equation of axis of symmetry is simply

[tex]x = h[/tex]

The given quadratic equation is

[tex]f(x) = {(x + 3)}^{2} - 8[/tex]

We can rewrite this as

[tex]f(x) = {(x - - 3)}^{2} - 8[/tex]

We now compare to

[tex]f(x) = a {(x - h)}^{2} + k[/tex]

We have

[tex]h = - 3 \: \: \: and \: \: k = - 8[/tex]

Therefore equation of axis of symmetry is:

Answer:

Volume = 784*pi

Step-by-step explanation:

We are given the height and radius of cylinder

So,

Radius = r = 7

Height = h = 16

The formula for finding volume of cylinder is:

[tex]Volume=\pi r^{2} h\\Putting\ in\ the\ values\ of\ r\ and\ h\\Volume=\pi *(7)^{2}*16\\V=\pi *49*16\\V=784\pi [/tex]

Answer:

Volume of cylinder = 784 cubic units

Step-by-step explanation:

Points to remember

Volume of cylinder =  πr²h

Where r - Radius of cylinder and

h - Height of cylinder

To find the volume of cylinder

It is given that,

radius r = 7 units and height h = 16 units

Volume of cylinder =  πr²h

 = π * 7² * 16

 = 784 cubic units

Therefore Volume of cylinder = 784 cubic units

Answer:

The solutions are: x=6. x=-4 and x=-8.

Step-by-step explanation:

The solution to the system of the equation is going to be given by the points where the graphs of:

y = x3 + 6x2 - 40x AND y = 192 intercept.

By looking at the graph, we can deduce they intercept at three points:

(-8, 192), (-4, 192) and (6, 192).

Another way to verify this, is by solving the following system of equations:

x3 + 6x2 - 40x - 192 = 0

Factorizing, we get:

(x-6)(x+4)(x+8) = 0

Where we can clearly see that the solutions are: x=6. x=-4 and x=-8.

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

Step-by-step explanation:

If you expand the brackets in -(3 - 2x) by multiplying all numbers by -1 (the negative symbol in front of the brackets represents negative 1 just without the 1)

Thus you get -3 + 2x.

Then rearranging the equation by swapping the 2x with the -3 you get 2x - 3.

ANSWER

[tex]y = \frac{1}{4}x+1[/tex]

EXPLANATION

The slope-intercept equation of a straight line is of the form

[tex]y = mx + b[/tex]

Where 'm' is the slope and 'b' is the y-intercept.

From the question we have slope to be

[tex]m = \frac{1}{4} [/tex]

We substitute the slope into the slope-intercept equation and obtain:

[tex]y = \frac{1}{4}x + b[/tex]

To find the value of 'b' we plug in the point (-8,-1) into our current equation.

[tex] - 1= \frac{1}{4}( - 8)+ b[/tex]

[tex] - 1= - 2+ b[/tex]

[tex] - 1 + 2 = b[/tex]

[tex]1 = b[/tex]

[tex]b =1 [/tex]

The complete equation is

[tex]y = \frac{1}{4}x + 1[/tex]

[tex]\frac{16x^2+48x}{8x} = 2x+6\\\frac{56x^2-14x}{7x} = 8x-2\\\frac{18x^2+15x}{3x}=6x+5\\\frac{20x^2-32x}{4x}=5x-8[/tex]

Step-by-step explanation:

We will solve the division one by one:

[tex]\frac{16x^2+48x}{8x} = \frac{8x(2x+6)}{8x} = 2x+6\\\frac{56x^2-14x}{7x}=\frac{7x(8x+2)}{7x}=8x+2\\\frac{18x^2+15x}{3x} =\frac{3x(6x+5)}{3x} = 6x+5\\\frac{20x^2-32x}{4x}=\frac{4x(5x-8)}{4x}=5x-8[/tex]

a)

[tex]\dfrac{16x^2+48x}{8x}[/tex]

Since, both the terms in the numerator have a common factor as: 8x.

Hence, we take out common 8x from the numerator term and hence it could be written as:

[tex]\dfrac{8x(2x+6)}{8x}[/tex]

i.e.

[tex]=2x+6[/tex]

b)

[tex]\dfrac{56x^2-14x}{7x}[/tex]

Since, both the terms in the numerator have a common factor as: 14x.

Hence, we take out common 14x from the numerator term and hence it could be written as:

[tex]=\dfrac{14x(4x-1)}{7x}\\\\=2(4x-1)\\\\=8x-2[/tex]

c)

[tex]\dfrac{(18x^2+15x)}{3x}[/tex]

Since, both the terms in the numerator have a common factor as: 3x.

Hence, we take out common 3x from the numerator term and hence it could be written as:

[tex]=\dfrac{3x(6x+5)}{3x}\\\\=6x+5[/tex]

d)

[tex]\dfrac{20x^2-32x}{4x}[/tex]

Since, both the terms in the numerator have a common factor as: 4x.

Hence, we take out common 4x from the numerator term and hence it could be written as:

[tex]=\dfrac{4x(5x-8)}{4x}\\\\=5x-8[/tex]

Hey there! :)

-4c + 3d = 8e ; solve for d.

In order to solve for d, you must isolate it (get it onto its own side). So, let's start off by adding 4c to both sides.

-4c + (-4c) + 3d = 8e + (-4c)

Simplify.

3d = 8e - 4c

Then, divide both sides by 3.

3d ÷ 3 = (8e - 4c) ÷ 3

Simplify.

d = 8/3e - 4/3c

Therefore, [tex]d = \frac{8}{3} e  -\frac{4}{3} c[/tex]
