what is 2x - 3 = 5 because i am doing a test for school

Answer: 12x^6y^3-28x^4y^5+8x^4y^4-4x^3y^4

Step-by-step explanation:

The requierd product of 4x³y³ and (3x³-7xy²+2xy-y) is:

12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

The monomial and the polynomial are given in the question, as follows:

4x³y³ × (3x³-7xy²+2xy-y)

To find the product of the monomial 4x³y³ and the polynomial (3x³-7xy²+2xy-y), we need to multiply each term in the polynomial by the monomial and then add the results.

(4x³y³) × (3x³) = 12x⁶y³

(4x³y³) ×  (-7xy²) = -28x⁴y⁵

(4x³y³) ×  (2xy) = 8x⁴y⁴

(4x³y³) ×  (-y) = -4x³y⁴

⇒ 12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴

Therefore, the product of 4x³y³ and (3x³-7xy²+2xy-y) is:

12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴

Answer:

h = 120

Step-by-step explanation:

The required, division of h=(500-260)divided by 2 is 120..

The division is a mathematical operation that involves distributing or sharing a quantity into equal parts. It is the inverse operation of multiplication. In division, a dividend is divided by a divisor to obtain a quotient.

h = (500 - 260) divided by 2

To solve this expression, we first perform the subtraction within the parentheses:

h = (240) / 2

Simplifying further:

h = 120

Therefore, the value of h is 120.

Answer:

2

Step-by-step explanation:

Number 2 was written wrong because it should have been 1 inch / 2.54 centimeters, not the other way around.

This is because the units of the number on the top of the previous one (in this case, centimeters) has to be the same as the units on the bottom of the fraction. This means that if you have cm on top of one, the next one has to have cm on the bottom of the fraction.

Step-by-step explanation:

y = 5x - 4

When x = 0, y = 5(0) - 4 = -4.

When x = 1, y = 5(1) - 4 = 1.

When x = 2, y = 5(2) - 4 = 6.

The 3 ordered pairs we have are (0,-4), (1,1) and (2,6).

We now check the point (-5,-29):

(-29) : 5(-5) - 4

-29 : -25 - 4

-29 : -29 => -29 = -29.

Since Left hand side = Right hand side, the point (-5,-29) is a solution.

Answer:

1. (1,1) (2,6) (3, 11)

2. Yes

Step-by-step explanation:

1. 5(1)-4 = 5-4 = 1

5(2)-4 = 10-4 = 6

5(3)-4 = 15-4 = 11

(I just chose 3 simple x values and plugged them into the equation to get the y values then wrote it as an ordered pair)

2. 5(-5)-4 = -25-4 = -29

-29 = -29

(Same as number 1 but I used the given x value then I checked if the y value I got matched the ordered pair)

hope this helps

Answer:

Step-by-step explanation:

We need the unit rate here. The best way to do this is to write a proportion.

Let x = the $ for 1 ft.

130/18 = x/1

130 = 18x

Divide by 18

x = $7.22

Now, we check to make sure we are correct.

130/18 = 7.22/1

130 = 130 ✅

Answer:

The fisherman row 6.4 miles total.

Step-by-step explanation:

Let the distance from his starting point to the  point he turn around is "d" miles.

Given  upstream speed is 2 mph and downstream speed is 8 mph.

We now that  time  =  distance /speed

So  the time required to row "d "miles upstream = d/2 hours

   The time required to row "d" miles downstream  = d/8 hours.

As the entire trip  took  2 hours  so the equation will be :

  d/2 +d/8  =  2

  ( 4d + d ) /8 =   2

  5d  =  16

  d  =   16/ 5 = 3.2 miles

So the fisherman rowed a total of  ( 3.2 x 2 ) miles =  6.4 miles.

Answer:

  D)  a = b= 2√2

Step-by-step explanation:

The hypotenuse of an isosceles right triangle is √2 times the side length. This means you have ...

  a√2 = 4

  a = 4/√2 = 4(√2)/2 = 2√2

Of course, the side lengths are the same (as all answer choices show you). The correct choice is ...

  a = 2√2, b = 2√2

(2,2) could be a solution. :)

(0,-8)  could be another.
