Use the graph or table to write a linear function that relates y to x

Answer:  n ≤ 52

Step-by-step explanation:

less than or equal to is usually write as ≤.

n - 15 ≤ 37

  +15    +15 [Add 15 to the both sides]      

     n ≤ 52

Step-by-step explanation:

Ok, so first...

a) if x is positive, it will remain x, so *x<7*

b) if x+3 is positive, it will be x+3<9 but you have to simplify it so you subtract 3 on both sides and get *x<6*

c) if y-8 is positive, it will stay like that, and you then add 8 on both sides to get *y>19*

g) if 3x-1 is positive, it will be 3x-1 greater than or equal to 18. add 1 on both sides and *3x > or = to 18*

4y+3 < or = 13. subtract 3 on both sides and you get *4y < or = 13*

One more thing:

Less than or equal to is a '<' with a line underneath.

Greater than or equal to is a '>' with a line underneath.

Step-by-step explanation:

caculator

Step-by-step explanation:

First we solve it.

I'll use substitution.

In the first equation y equals -2x+2 so we can apply that to the second equation

2y + 4x = 4

2(-2x+2) + 4x = 4

distribute

-4x+4+4x=4

simplify

4=4

To figure out how many solutions it has:

•If both side of the equal sign are exactly the same: Infinitely many

ex: 6x=6x

•If both sides of the equal sign do not match when completely simplified: No solutions

ex: 3x=-5x

•If it creates an equation: 1 solution

ex: x=3+2y

Since both sides of the equal sign are 4, we have infinitely many solutions.

Step-by-step explanation:

Train 1 speed be 'u'

Train 2 speed be 'v'

And v=2u

Speed=distance/time

Trains going in opposite directions

Relative speed= v-u (as train 1 I slower than train 2)

v-u=600/4

2u-u=150

u=150miles/hour

v=300miles/hour

The histogram showing the number of events with the events cost is

misleading because;

Please find attached a possible diagram of the histogram in the question

created with MS Excel;

The data in the histogram is presented as follows;

[tex]\begin{array}{|c|c|c}Event \ Cost&Number \ of \ Events\\1000- 1499&2\\1500-1999&4\\2000-2499&3\\3000-3499&1\end{array}\right][/tex]

From the above table, we have that the class with event cost of 2000 to

2499 is left out, therefore, the data is more clustered.

The correct option is therefore;

Answer:

x² + 8x + 16

Step-by-step explanation:

(x + 4)²

= (x + 4)(x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 4) + 4(x + 4) ← distribute parenthesis

= x² + 4x + 4x + 16 ← collect like terms

= x² + 8x + 16

The radioactive isotopes of an element are known as radioisotopes.  The radioisotope sample that is given is Barium-139.

The radioactive isotopes of an element are known as radioisotopes. Atoms with an unstable mix of neutrons and protons, or excess energy in their nucleus, are also known as neutron-proton atoms.

As it is given that the initial mass of the sample at 12:02:00 PM is,

[tex]m_1=104.8\ kg[/tex]

The Mass of the sample at 4:11:00 PM is given as

[tex]m_2 = 13.1 kg[/tex]

So here since it is a sample of radioactive isotope so here we will say

[tex]m_2=m_1e^{-\lambda t}[/tex]

Now from the above data, we know that the time taken to reduce the mass is

[tex]\rm t = 4\ hours\ 9\ minutes = 4.15\ hours[/tex]

Further, from the above equation, we will have

[tex]13.1 =104.8 e^{-\lambda(4.15)}\\\\\lambda(4.15)=2.08\\\\\lambda = 0.50/ hour[/tex]

So here half-life is given as

[tex]\rm T_{\frac12}=\dfrac{ln2}{\lambda}\\\\ T_{\frac12} = 1.4\ hours[/tex]

Thus, here this isotope must be the one that will have a half-life of 1.4 hours

Therefore, it is nearly Barium-139.

Hence, the radioisotope sample that is given is Barium-139.

Answer:

The actual length of the room is 40 feet

Step-by-step explanation:

Given

[tex]Scale = \frac{1}{2}\ inch : 12\ feet[/tex]

Required

Determine the actual measurement of [tex]3\frac{1}{3}\ inches[/tex]

Represent the required actual measurement with x

i.e.

[tex]3\frac{1}{3}\ inches : x[/tex]

And we have:

[tex]\frac{1}{2}\ inch : 12\ feet[/tex]

[tex]3\frac{1}{3}\ inches : x[/tex]

Cross Multiply

[tex]x * \frac{1}{2} = 12 * 3\frac{1}{3}[/tex]

Convert fraction to improper fraction

[tex]x * \frac{1}{2} = 12 *\frac{10}{3}[/tex]

[tex]\frac{x}{2} = \frac{120}{3}[/tex]

[tex]\frac{x}{2} = 40[/tex]

Multiply both sides by 2

[tex]x = 40 * 2[/tex]

[tex]x = 80\ feet[/tex]

The actual length of the room is 40 feet
