............................ .. sorry mate I also so busy so that. I can't all ur questions

Answer:

none of the above

Step-by-step explanation:

Answer:

(1,1)

Step-by-step explanation:

M=(x1+x2 / 2 , y1+y2 / 2)

M=(-2+4 / 2 , 4+ -2 / 2)

M=(2 / 2 , 2 / 2)

M=(1,1)

Answer:

4. 7 hours   6. 8.57

Step-by-step explanation:

Step-by-step explanation:

Since, Carlos completes the work in 5 hours.

So, in one hour she will do [tex] =\frac{1}{5}[/tex] part

Since, Jenny completes the work in 9 hours.

So, in one hour she will do [tex] =\frac{1}{9}[/tex] part

(Carlos + Jenny)'s one hour work together

[tex] =\frac{1}{5}+\frac{1}{9}\\

= \frac{9+5}{5\times 9}\\

= \frac{14}{45}\\[/tex]

Total time taken by Carlos and Jenny together [tex] =\frac{45}{14}= 3\frac{3}{14} \: hours[/tex]

Answer:

I think it is a sample space.

A sample space is, according to the dictionary,

"an experiment or random trial is the set of all possible outcomes or results of that experiment"

I'm sorry if I misunderstood.

Good luck mate! :)

Answer:

x = 3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2x+25=x+16

Step 2: Subtract x from both sides.

−3x+25=16

Step 3: Subtract 25 from both sides.

−3x=−9

Step 4: Divide both sides by -3

x=3

Answer:

(400/100)*80 = 320

Step-by-step explanation:

400 = 100%, just divide by 100 and multiply by 80

Answer:

80%of 400

400-80

400-80 =320

=320 people choose Friday

checking

320

80+20= 100

320+ 80=400

Unit walking rate in miles per hour = 5 2/3 / 2 2/3 = 17/3 / 8/3 = 17/3 x 3/8 = 17/8 = 2 1/8 miles per hour.

Unit walking rate in hours per mile = 1/ 17/8 = 8/17 hours per mile.

~you did not write the question properly but i guess this your needed answer

Answer:

2(4) + 3(4)³ ≠ 5(4)⁴

Step-by-step explanation:

To determine if the two expressions, 2y + 3y³ is the same as 5y⁴, we can set both expressions equal to each other. Then replace y with a value to find out, if what you have on the both sides are equal or not.

Thus: 2y + 3y³ = 5y⁴

Replace y with 4 in the equation

2(4) + 3(4)³ = 5(4)⁴

8 + 192 = 1,280

200 ≠ 1,280

What we have on one side of the equation is not equal to what we have in the other side. So therefore, both expressions are not equal. Hence, they are not the same.

The statement that shows 2y + 3y³ and 5y⁴ are not the same is:

2(4) + 3(4)³ ≠ 5(4)⁴

Answer:

[tex] \boxed{ \bold{ \huge{\boxed{ \sf{x = - 11}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{5x + 23 = 2(x - 5)}[/tex]

Distribute 2 through the parentheses

⇒[tex] \sf{5x + 23 = 2x - 10}[/tex]

Move 2x to left hand side and change it's sign

⇒[tex] \sf{5x - 2x + 23 = - 10}[/tex]

Move 23 to right hand side and change it's sign

⇒[tex] \sf{5x - 2x = - 10 - 23}[/tex]

Collect like terms

⇒[tex] \sf{3x = - 10 - 23}[/tex]

Calculate

⇒[tex] \sf{3x = - 33}[/tex]

Divide both sides of the equation by 3

⇒[tex] \sf{ \frac{3x}{3} = \frac{ - 33}{3} }[/tex]

Calculate

⇒[tex] \sf{x = - 11}[/tex]

Hope I helped!

Answer:

75

Step-by-step explanation:

Let full marks be x

Then pass marks is 40% of x which is 0.4x

As per given, we have

22= 0.4x - 8

Solving for x

0.4x = 30

x = 30/0.4

x = 75

So full marks is 75

Answer:

Three decimals

Step-by-step explanation:

Two decimals coming from the first number and one coming from the second one: 4.393 is the product

Answer:

3 decimal places (the answer to the equation is 4.393)

Step-by-step explanation:

When multiplying decimals, multiply them as whole numbers, count the amount of decimal places and both, add the number of decimal places up, and that's how many decimal places are in your answer.  So the first one has two decimal places and the second one has one decimal places making your answer have three decimal places.  

Answer:

C. y-1=2(x+2)

Step-by-step explanation:

A. y-7=2(x-6)-point slope form: y-y1=2(x-x1)-coordinate point: (x1,y1)=(6,7)

Now let's check that the other point works-just sub in the coordinates for the x and y variables.

y-7=2(x-6)\\-1-7=2(2-6)\\-8=2(-4)\\-8=-8

So answer choice A. goes through both points, so no.

B. y=2x-5-slope-intercept form, so just sub in both sets of coordinates separately to see if they each work.

y=2x-5\\7=2(6)-5\\7=12-5\\7=7\\equal

y=2x-5\\-1=2(2)-5\\-1=4-5\\-1=-1\\equal

Both work, so no.

C. y-1=2(x+2)-point slope form that gives us first coordinate set--(-2,1)

Except that the point is actually (2,-1) not (-2,1).  That means that answer choice C is not an equation of the line thaat goes through (6,7) and (2,-1), so yes.

D. Anyway, if we check D--y+1=2(x-2)--coordinate point given: (2,-1), which is correct, so no.

Answer:

La nota que Víctor no recuerda es 5.2

Step-by-step explanation:

La media es el valor promedio de un conjunto de datos numéricos y es también llamada promedio o media aritmética.

Su cálculo se obtiene al sumar todos los datos disponibles y dividir el resultado por el número total de esos datos:

[tex]Promedio=\frac{x_{1} +x_{2} +x_{3}+...+x_{n} }{N}[/tex]

donde N el número total de observaciones.

En este caso:

[tex]Promedio=\frac{x_{1} +x_{2} +x_{3}+x_{4} }{4}[/tex]

Siendo:

y reemplazando:

[tex]5.5=\frac{6 +6 +4.8+x_{4} }{4}[/tex]

Se obtiene:

5.5*4=6+6+4.8 +x₄

22=6+6+4.8 +x₄

22-6-6-4.8=x₄

x₄=5.2

Answer:

[tex]x = \frac{1}{4}[/tex]

Step-by-step explanation:

[tex]-50 = -5x - 3(5x + 15)[/tex]

Use -3 to open the bracket

[tex]-3(5x +15)\\\\= -15x -45\\\\ -50 = -5x-15x -45[/tex]

Collect like terms

[tex]-50 +45 =-5x -15x[/tex]

Simplify

[tex]-5 = -20x[/tex]

Divide both sides of the equation by -20

[tex]\frac{-5}{-20} = \frac{-20x}{-20} \\\\1/4 =x\\\\x = \frac{1}{4}[/tex]

Answer:

The number line is shown below.

Step-by-step explanation:

We need to represent number that is less than 3 on a number line.

Let x be numbers.

So, [tex]x<3[/tex].

Now, we have a number which represents x<3. Here 3 is not included in the solution set, so there is an open circle on 3 and left side of 3 are in the solution set.

The number line is shown below.
