HELP ME PLEASE!!! i’m really confused

Answer

the answer is -9≤x≤9

Answer:

x = (-9,9)

Step-by-step explanation:

|x |< 9 - seperate the inequality into 2 possible cases

1. x<9, x>0   -x<9, x<0

find the intersection

x = (0,9)    -x<9, x<0

find the intersection again

x = (0,9)   x = (-9,0)

find the union

x = (-9,9)

Answer:

Quick question, did you find the answer?

Answer:

Step-by-step explanation:

y=mx+b where m=slope and b=y intercept

m=(y2-y1)/(x2-x1), we have points (0,0) and (4,12)

m=(12-0)/(4-0)=12/4=3

y=3x+b, using point (4,12) we can solve for b

12=3(4)+b

12=12+b

b=0 so the line is

y=3x

Answer:

A) Leo comió más, ya que comió 1/2 de la pizza.

B) Joel y Evelio comieron menos, ya que comieron 1/8 de la pizza.

C) Asimismo, Joel y Evelio comieron igual, ya que cada uno comió 1/8 de la pizza.

D) En total, entre todos comieron una pizza.

Step-by-step explanation:

Dado que cuatro amigos compraron una pizza, de la cual Leo se comió 1/2, Adán 1/4, Joel 1/8 y Evelio se comió lo que sobró, para determinar quién comió más, quién comió menos, quiénes comieron igual y cuántas pizzas se comieron en total se deben realizar los siguientes cálculos:

1/2 + 1/4 + 1/8 + X = 1

4/8 + 2/8 + 1/8 + X = 1

7/8 + X = 1

X = 1 - 7/8

X = 1/8

Step-by-step explanation:

                                   Males                 Females    Total

Soccer                           19                          31             50

basketball                     21                           29           50

Total                              40                          60         100

Number of males Whose favorite sports is soccer = 50 - 31 = 19

Number of females Whose favorite sports is basket ball = 50 - 21 = 29

Part B)

B.Equal number of people like soccer and basketball. - True

C. More females like soccer   - True

Answer:

Sam will roll a 3 or 4 about 200 times

Step-by-step explanation:

Answer:

Step-by-step explanation:

It takes 15 years to get 2.5 times the sum at 10% p.a.

Let the principal be 'P'.

Let the amount be '2.5P'

Rate = 10%

Amount = Principal - Interest

2.5 P = P - Interest

Interest = 1.5 P

So, we get that

[tex]1.5P =\frac{P*R*T}{100} \\1.5 * 100 = 10 * T\\T = 15 years[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

f(x) = 1 - x²

g(x) = [tex]\sqrt{11-4x}[/tex]

[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

[tex](\frac{f}{g})(x)=\frac{1-x^2}{\sqrt{11-4x}}[/tex]

[tex](\frac{f}{g})(-1)=\frac{1-(-1)^2}{\sqrt{11-4(-1)}}[/tex]

             = [tex]\frac{1-1}{\sqrt{15}}[/tex]

             = 0

(g + f)(x) = g(x) + f(x)

             = [tex]\sqrt{11-4x}+1-x^2[/tex]

(g + f)(2) = [tex]\sqrt{11-4(2)}+1-(2)^2[/tex]

             = [tex]\sqrt{3}-3[/tex]

(g - f)(x) = g(x) - f(x)

            = [tex]\sqrt{11-4x}-(1-x^2)[/tex]

            = [tex]\sqrt{11-4x}-1+x^2[/tex]

(g - f)(-1) = [tex]\sqrt{11-4(-1)}-1+(-1)^2[/tex]

             = [tex]\sqrt{15}[/tex]

(g . f)(x) = g(x) × f(x)

            = [tex](\sqrt{11-4x})(1-x^2)[/tex]

(g . f)(2) = [tex](\sqrt{11-4(2)})(1-(2)^2)[/tex]

             = [tex]\sqrt{3}(-3)[/tex]

             = -3√3

Answer:

third side of. TRAINGLE is hypotenuse

=√(9²+7²)=11.04

therefore given figure is rectangle

dotted line is hypotenuse

=√(9²+11.04²)=14.24 unit

Answer:

In the case of 4 tickets it can be possible

Step-by-step explanation:

Let us assume the number of tickets be t

Now as per the question the equations would be

For you  = t + $8

For your friend = t + $12

In the case when you both spend the same amount so the above equations would be equivalent to each other

t + $8 = t + $12

So here the tickets would be 4 so this is possible that you both spend the same amounts

Because we know what x is, we plug in 7 to the expression.

7+3<9

Since 7+3 is 10, then the new expression is 10<9.

I have no idea if this is a true/false question, because this statement is false.

Answer:

y=2x-2

Step-by-step explanation:

Answer:

Step-by-step explanation:

To find the line y=mx+b we need two points. I choose (0,-2) and (1,0)

Since y=mx+b where m=slope and b=y intercept (value of y when x=0)

We have the point (0,-2) so we know b=-2

Now we find the slope which is defined as

m=(y2-y1)/(x2-x1), in this case

m=(0-(-2))/(1-0)

m=2, so the line is

y=2x-2
