solve (x^3-4x)(2x^2-3x)​

Step-by-step explanation:

2 squared plus 2 =5

5+2x =7x

7x-3 = 4x

We need to set up and solve all of the angle measures add up to 180°

[tex]3x - 10 + 6x + 5 + 4x - 10 = 180\\\\7x - 15 = 180\\\\7x = 165\\\\x = 24[/tex]

Answer: x= -2/3

Step 1: Subtract 6x from both sides.

15x+8−6x=6x+2−6x

9x+8=2

Step 2: Subtract 8 from both sides.

9x+8−8=2−8

9x=−6

Step 3: Divide both sides by 9.

Answer:

a) [tex]\left \{ {{8x+218=y} \atop {5x+521=y}} \right.[/tex],   b) $101

Step-by-step explanation:

Hermes: 8 envelopes, $218

Apollo: 5 envelopes, $521

If x is the amount in each envelope, H is the amount Hemes has and A is the amount Apollo has, this would be a possible system of equations.

[tex]\left \{ {{8x + 218 = H} \atop {5x +521 = A}} \right.[/tex]

If Apollo and Hermes both had the same amount of total money, A and H could equal y

[tex]\left \{ {{8x+218=y} \atop {5x+521=y}} \right.[/tex]

We want to find the amount in each envelope (x), so we can substitute y in the first equation for y in the second equation:

[tex]8x+218=5x+521[/tex]

Subtract [tex]5x[/tex] from both sides

[tex]3x+218=521[/tex]

Subtract 218 from both sides

[tex]3x=303[/tex]

Divide both sides by 3

[tex]x=101[/tex]

So there would have to be $101 in both envelopes for Apollo and Hermes to have the same amount of total money.

140 adults and 72 children

Step-by-step explanation:

-4a-4c=-848

6a+4c=1128

2a=280

a=140

the answer Is b

2.5

The situation is represented by the table:

The tank initially had 1200 gallons of water.

The tank is leaking at the rate of 2.5 gallons per hour.

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

From the table, we see that,

After 4 hours there are 1190 gallons of water left.

After 8 hours there are 1180 gallons of water left.

Now,

The rate of change.

= (1180 - 1190)/ (8 - 4)

= -10/4

= -5/2

= -2.5

This means,

There is a decrease of 2.5 gallons per hour.

Now,

The amount of water the tank initially had.

= 1190 + 4 x 2.5

= 1190 + 10

= 1200

Thus,

The tank initially had 1200 gallons of water and it's leaking at the rate of 2.5 gallons per hour.

Given:

The vertices of a polygon are A (−1, 1), B (4, 1), C (4,−2), and D(−1,−2).

To find:

The perimeter of ABCD.

Solution:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using distance formula, we get

[tex]AB=\sqrt{(4-(-1))^2+(1-1)^2}[/tex]

[tex]AB=\sqrt{(4+1)^2+(0)^2}[/tex]

[tex]AB=\sqrt{(5)^2}[/tex]

[tex]AB=5[/tex]

Similarly,

[tex]BC=\sqrt{(4-4)^2+(-2-1)^2}=3[/tex]

[tex]CD=\sqrt{(-1-4)^2+(-2-(-2))^2}=5[/tex]

[tex]AD=\sqrt{(-1-(-1))^2+(-2-1)^2}=3[/tex]

Now, perimeter of ABCD is

[tex]P=AB+BC+CD+AD[/tex]

[tex]P=5+3+5+3[/tex]

[tex]P=16[/tex]

Therefore, the perimeter of ABCD is 16 units.

The perimeter of polygon ABCD is 16 units

The coordinates are given as:

[tex]\mathbf{A = (-1,1)}[/tex]

[tex]\mathbf{B = (4,1)}[/tex]

[tex]\mathbf{C = (4,-2)}[/tex]

[tex]\mathbf{D = (-1,-2)}[/tex]

Start by calculating the distance between the coordinates using the following distance formula

[tex]\mathbf{d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}}[/tex]

So, we have:

[tex]\mathbf{AB = \sqrt{(-1 - 4)^2 + (1 - 1)^2} = 5}[/tex]

[tex]\mathbf{BC = \sqrt{(4 - 4)^2 + (-2 - 1)^2} = 3}[/tex]

[tex]\mathbf{CD = \sqrt{(4 - -1)^2 + (-2 - -2)^2} = 5}[/tex]

[tex]\mathbf{AD = \sqrt{( -1- -1)^2 + (-2 - 1)^2} = 3}[/tex]

The perimeter is then calculated as:

[tex]\mathbf{Perimeter = AB + BC + CD + AD}[/tex]

Substitute values for AB, BC, CD and DA

[tex]\mathbf{Perimeter = 5+ 3 + 5 + 3}[/tex]

[tex]\mathbf{Perimeter = 16}[/tex]

Hence, the perimeter of the polygon is 16 units

Answer:

The equation in point-slope form is: [tex]y+4=\frac{-1}{10}(x+1)[/tex]

Step-by-step explanation:

Write the equation of the line that passes through the points (-1,-4) and (9,-5).

The point slope form is:  [tex]y-y_1=m(x-x_1)[/tex]

Where m is slope and x₁ and y₁ are the points given

Finding Slope

Slope can be found of given points using formula:  [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have  [tex]x_1=-1, y_1=-4, x_2=9, y_2=-5[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-5-(-4)}{9-(-1)}\\ Slope=\frac{-5+4}{9+1}\\ Slope=\frac{-1}{10}[/tex]

So, slope m = -1/10

Using point (-1,-4) and slope m = -1/10 the equation is:

[tex]y-y_1=m(x-x_1)\\y-(-4)=\frac{-1}{10}(x-(-1))\\y+4=\frac{-1}{10}(x+1)[/tex]

So, the equation in point-slope form is: [tex]y+4=\frac{-1}{10}(x+1)[/tex]

Step-by-step explanation:

trust me bro

Answer: Cr<Fr

Step-by-step explanation:

if you look at the angle it gives you, you can tell which inequality is bigger.

The sum of the equation is A = x² + x + 1

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 sum of the equations be represented as A

Now , the value of A is

Let the first equation be P

The value of P = 3x² + 4x - 1

Let the second equation be Q

The value of Q = -2x² - 3x + 2

Now , the value of A = P + Q

Substituting the values in the equation , we get

A = ( 3x² + 4x - 1 ) + ( -2x² - 3x + 2 )

On simplifying the equation , we get

A = ( 3x² - 2x² ) + ( 4x - 3x ) + ( 2 - 1 )

A = x² + x + 1

Therefore , the value of A is x² + x + 1

Hence , the equation is A = x² + x + 1

Answer:

4 9/20

Step-by-step explanation:

Convert the mixed fractions to improper fractions first:

7 1/4--> 29/4, 2 4/5--> 14/5.

Now we look for the common denominator, which is 20. So 29/4=145/20 and 14/5=56/20.

We subtract them:

145/20-56/20=89/20.

Convert it to a mixed fraction to get 4 9/20.

The difference of the given mixed fractions is [tex]4\frac{9}{20}[/tex].

Given that, [tex]7\frac{1}{4} -2\frac{4}{5}[/tex].

Subtracting fractions include the subtraction of two or more fractions with the same or different denominators. Like fractions can be subtracted directly but for unlike fractions we need to make the denominators same first and then subtract them.

Here, [tex]7\frac{1}{4}[/tex] can be written as 29/4 and [tex]2\frac{4}{5}[/tex] can be written as 14/5

Now, 29/4 - 14/5

= 145/20 - 56/20

= 89/20

= [tex]4\frac{9}{20}[/tex]

Therefore, the difference of the given mixed fractions is [tex]4\frac{9}{20}[/tex].
