Which graph shows the system of equations 4 x + y = 3 and 2 x minus 3 y = 3?

Answer:

x= 37/12

Step-by-step explanation:

HOW DO I START?

Don't worry, you know that this problem only has two small steps, and it's done, it should take less than 45 seconds to complete.

WE ALWAYS WANT TO ISOLATE THE VARIABLE TO FIND Y: MAKE IT BE ALONE!

STEP 1: Subtract 12 from both sides, to start getting 5y alone.

NOW YOU HAVE: 5y = 20

STEP 2: Divide by 5 from both sides, to get the Y fully alone.

NOW YOU HAVE: y = 4

Answer:

55,000 Joules,

Step-by-step explanation:

Kinetic energy = 1/2 *mass * velocity^2

= 1/2 * 44 * 50^2

= 55,000 Joules,

Formula for the area of a face of a cube: A = length x width

Let's find the area of one face.

A = 5 x 5

A = 25

Now, let's multiply the area of one face by 6 because a cube has 6 faces.

25 x 6 = 150

A = 150 square centimeters

Answer:

The probability that the socks picked is not blue is 11/14

Step-by-step explanation:

In this question, we are to calculate that a socks selected from random from the group of socks given in the question is not a blue socks.

This means the socks would either be a black or a white socks

Firstly, we find the total number of socks = 8 + 6 + 14 = 28 socks

Now the probability of picking a blue socks will be 6/28 = 3/14

We must understand that the probability of not picking a blue socks = 1 - the probability of picking a blue socks

Thus, the probability of not picking a blue socks will be 1 - 3/14 = 11/14

Answer:

The probability that a sock chosen at random is not blue P = 11/14 = 0.786

Step-by-step explanation:

Probability is the chances of getting a particular outcome.

Given:

Black socks = 8

Blue socks = 6

White socks = 14

Total = 8+6+14 =28

The probability that a sock chosen at random is not blue P;

P = number of non-blue socks ÷ total number of socks

Number of non blue socks = black + white socks = 8+14 = 22

Substituting the values;

P = 22/28 = 11/14

P = 11/14 = 0.786

Step-by-step explanation:

Answer:

The circumference for circle a is [tex] \\ C = 131.9430[/tex]m.

The circumference for circle b is [tex] \\ C = 175.9240[/tex]m.

The relationship between the radius of a circle and the circumference (the distance around the circle) is constant and is the same for all circles and can be written as [tex] \\ \frac{C}{r} = 2\pi[/tex] or, in a less familiar form, [tex] \\ \frac{r}{C} = \frac{1}{2\pi}[/tex]. The number [tex] \\ \pi[/tex] is constant for all circles and has infinite digits, [tex] \\ \pi = 3.14159265358979....[/tex].

Step-by-step explanation:

The circumference of a circle is given by:

[tex] \\ C = 2*\pi*r[/tex] [1]

Where

[tex] \\ C[/tex] is the circle's circumference.

[tex] \\ r[/tex] is the radius of the circle.

And

[tex] \\ \pi = 3.141592....[/tex] is a constant value (explained below)

We can say that the distance around the circle is the circle's circumference.

The circumferences of the two circles given are:

Circle a, with radius equals to 21 meters ([tex] \\ r = 21m[/tex]).

Using [1], using four decimals for [tex] \\ \pi[/tex], we have:

[tex] \\ C = 2*\pi*r[/tex]

[tex] \\ C = 2*3.1415*21[/tex]m

[tex] \\ C = 131.9430[/tex]m

Then, the circumference for circle a is [tex] \\ C = 131.9430[/tex]m.

Circle b, with radius equals to 28 meters ([tex] \\ r = 28m[/tex]).

[tex] \\ C = 2*3.1415*28[/tex]m

[tex] \\ C = 175.9240[/tex]m

And, the circumference for circle b is [tex] \\ C = 175.9240[/tex]m.

We know that

[tex] \\ 2r = D[/tex]

That is, the diameter of the circle is twice its radius.

Then, if we take the distance around the circle and we divided it by [tex] \\ 2r[/tex]

[tex] \\ \frac{C}{2r} = \frac{C}{D} = \pi[/tex]

This ratio, that is, the relationship between the distance around the circle (circumference) and the diameter of a circle is [tex] \\ \pi[/tex] and is constant for all circles. This result is called the [tex] \\ \pi[/tex] number, which is, approximately, [tex] \\ \pi = 3.141592653589793238....[/tex] (it has infinite number of digits).

We can observe that the relationship between the radius of a circle and the circumference is also constant:

[tex] \\ \frac{C}{2r} = \frac{C}{D} = \pi[/tex]

[tex] \\ \frac{C}{2r} = \pi[/tex]

[tex] \\ \frac{C}{r} = 2\pi[/tex]

However, this relationship is [tex] \\ 2\pi[/tex].

We can rewrite it as  

[tex] \\ \frac{r}{C} = \frac{1}{2\pi}[/tex]

And it is also constant.

Circle A is 42π

Answer:

10 miles

Step-by-step explanation:

∠1 = 70° and ∠3 = 40°.  Angles of a triangle add up to 180°, so ∠2 = 70°.

Using law of sines:

10 / sin(∠2) = x / sin(∠1)

10 / sin(70°) = x / sin(70°)

x = 10

Answer:

Therefore Jet Skis cost $50 for the rental and Kayaks cost $20.

Step-by-step explanation:

Since they both rent the vehicles at the same price, "x" for jet skis and "y" for kayaks", we can create equations for each store and a system of equations for these, as shown below:

Watersports:

12*x + 9*y = 780

Fun Rentals:

7*x + 11*y = 570

System:

[tex]\left \{ {{12*x + 9*y=780} \atop {7*x + 11*y=570}} \right.[/tex]

We can isolate "x" on the first equation:

[tex]x = \frac{780 - 9*y}{12}[/tex]

And use it on the second:

[tex]7*[\frac{780 - 9*y}{12}] + 11*y = 570\\5460 -63*y = 6840 - 132*y\\132*y - 63*y = 6840 - 5460\\69*y = 1380\\y = 20\\[/tex]

We can now use this value to find "x":

[tex]x = \frac{780 - 9*20}{12} = 50[/tex]

Therefore Jet Skis cost $50 for the rental and Kayaks cost $20.

Answer:

[tex]- 7 + \frac{2}{3}n = 13 : n = 30[/tex]

Step-by-step explanation:

[tex]-7+\frac{2}{3}n=13[/tex]

Add [tex]7[/tex] to both sides:

[tex]-7+\frac{2}{3}n+7=13+7[/tex]

Simplify:

[tex]\frac{2}{3}n=20[/tex]

Multiply both sides by [tex]3[/tex]:

[tex]3 * \frac{2}{3}n=20 * 3[/tex]

Simplify:

[tex]2n=60[/tex]

Divide both sides by [tex]2[/tex]:

[tex]\frac{2n}{2}=\frac{60}{2}[/tex]

Simplify:

[tex]n = 30[/tex]

Answer:

The slope is 3/2

Step-by-step explanation:

To find slope you do rise over run

Rise being how much you go up or go down

Run being how much you move sideways

Always measure Rise first, it is the numerator and then Run as the denominator.

Answer:

m= 3/2.

Step-by-step explanation:

To find the slope, use the two points shown in the graph which as (-1, 2) and (1, 5). Plug these into the slope formula [tex](m= \frac{y_{2}-y_{1} }{x_{2}-x_{1}} )[/tex]

[tex]m= \frac{5-2 }{{1+1}}[/tex]

[tex]m= \frac{3}{2}[/tex]

Therefore, the slope of the graph is 3/2.
