Answer:

2.7

Step-by-step explanation:

For (5x−2+3x^2)+(4x+3)  the answer is below

Answer:

the answer is 40 boys

Step-by-step explanation:

Let's say there are x boys who play both cards and carrom.

We setup up an equation that involved all information given and x.

Boys who only play cards = 45-x

Boys who only play carrom = 20-x

Boys who play both = x

Add there together and you should get 60, which is the total number of students in the class.

(45-x)+(20-x)+x=60

65-x=60

x=5

Boys who only play cards=45-x=45–5=40

hope it helps you

Answer:

there are 15 boys who can play both games in the class.

Answer: The last one.

Step-by-step explanation:

Answer:

Answer A is the correct option.

Answer:

3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (- 3, - 1)

d = [tex]\sqrt{(-3-0)^2+(-1+4)^2}[/tex]

   = [tex]\sqrt{(-3)^2+3^2}[/tex]

   = [tex]\sqrt{9+9}[/tex]

   = [tex]\sqrt{18}[/tex]

   = [tex]\sqrt{9(2)}[/tex]

    = [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Hey there!

Given;

The points are;(0,-4) and (-3,-1).

Use formula for distance between the two points.

[tex]d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]

Put all values.

[tex]d = \sqrt{( { - 3 - 0)}^{2} + ( { - 1 + 4)}^{2} } [/tex]

Simplify to get answer.

[tex]d = \sqrt{9 + 9} [/tex]

[tex]d = \sqrt{18} [/tex]

[tex]d = 3 \sqrt{2} [/tex]

Therefore, the distance is 3√(2) units or 4.24 units.

Answer:

$62

Step-by-step explanation:

Take $46.50 and divide it by 3 to get 1/4 of the paycheck

46.50/3 = 15.50

Then multiply 15.50 by 4 to get the whole pay check

15.50 x 4 = 62

Answer:

-6, 5, 0, and -2

Step-by-step explanation:

The domain values are the x-values in a coordinate pair. Therefore, the domains would be -6, 5, 0, and -2.

Answer:180 minus 79 is 101

Step-by-step explanation:

Answer:

One solution

Step-by-step explanation:

12x+96=11x-5

12x-11x= -5-96

x= -101

x only equals one solution, which is -101.

Answer:

ASSOCIATIVE PROPERY

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Evaluate g(5), then use the value obtained to evaluate f(x) , that is

g(5) = 2(5)² - 4(5) = 2(25) - 20 = 50 - 20 = 30, then

f(30) = 3(30) + 2 = 90 + 2 = 92

Answer:

43 Is a prime number

=================================================

Explanation:

Replace every x with -3

Then use the order of operations (PEMDAS) to simplify

y = -2x^2 + x - 5

y = -2(-3)^2 + (-3) - 5 ... x replaced with -3

y = -2(9) - 3 - 5

y = -18 - 3 - 5

y = -21 - 5

y = -26

Answer:

-26

Step-by-step explanation:

1. plug in -3 for all x's

  -2(-3)^2 + (-3) -5

2. combine like terms

  -2(-3)^2 - 8

3. pEmdas. deal with exponent first (remember: only affect the 3, since it's in parentheses! also when you square a negative number, it becomes positive!)

  -2(9) - 8

4. peMdas. multiply -2 and 9 next.

  -18 - 8

5. pemdaS. subtract 8 from -18.

  -18 - 8 = -26

Answer:

the x is -8,0 and the y is 0,2

Answer:

The coldest temperature at Antarctica is -89.6 degrees celsius

Step-by-step explanation:

Here, we are interested in calculating the coldest temperature in Antarctica.

In the question, we are simply told that the coldest Antarctica temperature was 40.6 colder than the average winter temperature at the south pole.

The average winter temperature at south pole = -49 degree celsius

The coldest temperature is thus -49-40.6 = -89.6 degrees celsius

sorry if im wrong

Answer:

they won 52 games

they lost 19 games

the equation is  2x + 33= 71

Step-by-step explanation:

they played 71 games in total

say the amount of games they won is y

say the amount of games they lost is x

using the variables, you can form this equation:

y + x = 71

you also know that they won 33 more games then they lost.

so, y = x + 33

now, you can substitute y for x + 33 in the original equation

x + x + 33 = 71

combine like terms

2x + 33 = 71

subtract 33 from both sides of the equation

2x + 33 - 33 = 71 - 33

2x = 71 - 33

2x = 38

divide both sides of the equation by 2

2x/2 = 38/2

x = 38/2

x = 19

they lost 19 games.

now substitute 19 for x in the equation

y = x + 33

y = 19 + 33

y = 52

they won 52 games

Answer:
