( 2X³ - 5X² + 3X - 10 ) - ( X³ - 7X + 4 )

2X³ - 5X² + 3X - 10 = X² - 10

X³ - 7X + 4 = - 7X² + 4

X² - 10 - - 7X² + 4 =

Answer:

3/2

Step-by-step explanation:

Taking the point at (1, -3) and (3, 0) and getting the rise-over-run will give you the answer. 0 - (-3) = 3 for rise, and 3 - 1 = 2 for run.

Answer:

5/18

Step-by-step explanation:

first you want to flip 2/5 to 5/2 and change the division sign to multiplication so it would look like 1/9 x 5/2

then multiply 1 and 5 then 9 and 2 so the top and bottom to get 5/18

side note: but if it were 1/9 x 3/7 you would change the 3 to a 1 and the 9 to a 3 because they multiply so ask yourself how many times does three go into 9 so it would be 1/3 x 1/7= 1/21

hope this helped :) also what math are you taking bc if it is under algebra 1 or something i can help with any questions you have just message me and ill be happy to help :)

Answer:

You would distribute the imaginary 1 to 4w cubed and then do the same to the other side as well so 1 times-2w cubed would still be -2w and then 4w cubed would still be 4v  and the answer is: -8v^3w^4

Answer:

32 square feet

Step-by-step explanation:

From the above question, we know that: for Newman:

8 ft² = 1/4hour

x ft² = 1 hour

We Cross Multiply

8ft² × 1 hour= x ft² × 1/4hour

xft² = 8ft² × 1 hour/1/4 hours

x ft² = 32 ft²

Therefore, Newman installs 32 square feet per hour

The difference between the expression and an equation is explained below:

The equation represents the mathematical value while the expression could include the numbers, letters, etc. The expression should be treated as phrases while the equations are considered to be complete sentences. The expression does not show any kind of relations while the equation should show the relationship.

In this way, it should be differentiated.

Step-by-step explanation:

Answer:

Rational.

Step-by-step explanation:

If a number is rational it can be expressed in a fraction [tex]\frac{x}{y}[/tex] where x and y are integers.

[tex]6.2=\frac{62}{10} = \frac{31}{5}[/tex]

Since 6.2 can be expressed in a fraction, it is rational.

Answer:

120 pages can be printed in 1 hour.

Step-by-step explanation:

First divide 36 by 18 to figure out how many pages can be printed in a minute.

Like this: 36 pages ÷ 18 minutes = 2 pages in one minute.

Now, multiply 2 by 60 to figure out how many pages can be printed out in a hour.

Like this: 2 pages in one minute × 60 minutes ( one hour) = 120 pages in one hour can be printed.

Answer:

100n+250t

Step-by-step explanation:

cost of the1 one day pass=100

cost of n one day passes=100n

cost of the 1 three day pass=250

cost of t three day passes=250t

Total sale= 100n+250t

The expression for the total ticket sales if (n) one day passes and (t) three day passes are sold is n + t = $350.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Cost of one-day passes, n = $100

Cost of three-day passes, t = $250

So, Total tickets sold = Cost of one-day passes + Cost of three-day passes

⇒ Total tickets sold = n + t

⇒ n + t = $100 + $250

⇒ n + t = $350

which is the required expression for total tickets sold.

Thus, the expression for the total ticket sales if (n) one day passes and (t) three day passes are sold is n + t = $350.

Answer: 4 9/25

Step-by-step explanation:

Answer:

Step-by-step explanation:

(x + 0)/2 = 6

x + 0 = 12

x = 12

(y + 4)/2 = -7

y + 4 = -14

y = -18

(12, -18)

The coordinate of the point S will be (12,-18).

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line.

Given that the coordinates of point T are (0,4). The midpoint of ST is (6,-7). The coordinates of the point S will be calculated as below:-

The x-coordinate is calculated as below:-

(x + 0)/2 = 6

x + 0 = 12

x = 12

The y-coordinate is calculated as below:-

(y + 4)/2 = -7

y + 4 = -14

y = -18

Therefore, the coordinate of the point S will be (12,-18).

Answer:

Step-by-step explanation:

In this problem, we are told that Delia bought 4.5 pounds of fruit

and paid with a toa total bill of 20+5= 25 bill

and also she received a  change of 3.67

this means that the item she bought cost 25-3.67= 21.33bill

now if 4.5 pounds of items cost 21.33 bill

then 1 pound will cost Xbill

cross multiply and solve for Xbill

X= 21.33/4.5

X= 4.74 bill

One pound of the item will cost 4.74 bill

Answer:

Option (A)

Step-by-step explanation:

From the given piecewise function that represent the amount of bill from number of units of electricity used is 'x' kWh.

b(x) = 0.10x   when x ≤ 200

         0.15(x - 200) + 20  when x > 200

For x = 400 kWh,

Function which represents the expenses of the bill,

b(400) = 0.15(400 - 200) + 20 [Since x > 200]

           = 0.15(200) + 20

           = 30 + 20

           = $50

Therefore, Option (A) will be the answer.
