Resolver por igualación 2x+3y=2 6x+12y=1

Mathematics
1 answer:
tigry1 [53]2 years ago
5 0

Answer:

x = 3.5

y\approx1.666666667

Step-by-step explanation:

To solve simultaneous equations, at least one of our variables must have the same coefficient. We can easily multiply the first equation by 4 to get 12y on both sides, so let's do that:

8x + 12y = 8

No let's subtract the second equation from the first equation to get the third equation:

2x = 7

Solve:

x = 3.5

Now, we can substitute this value into one of the original equations - let's use the second one:

21 + 12y = 1

Solve:

12y =  - 20

y =  - \frac{ - 20}{12}  =  \frac{ - 10}{6}  =   - \frac{5}{3} \approx - 1.66666666667

colby has 16 jars of spices.He wants to arrange them in arrays. what arrays could he use to arrange them
Darya [45]

Answer:

He has 5 ways to arrange them in a array.

Step-by-step explanation:

colby has 16 jars of spices.He wants to arrange them in arrays.

<em>An array is a systematic arrangement of similar objects, usually in rows and columns.</em>

So, the choices he could have to form an array is the possible number of ways he can arrange them in rows and columns and in table it could be seen as:

S.no.                  Number of rows              Number of columns

1                                16                                           1

2                                8                                           2

3                                 4                                           4

4                                 2                                           8

5                                  1                                          16

Hence, the number if arrays he could use to arrange them is 5.

Find an equation of the circle whose diameter has endpoints (1,-4) and (-3,6).
MAVERICK [17]

Answer:

(x+1)^2+(y-1)^2=58

Step-by-step explanation:

To find the equation of this circle, we must know the center and the radius.

We can find the radius by dividing the value of the distance formula by 2 (since r=\frac{d}{2}):

d=\sqrt{(-3-1)^2+(6-(-4))^2}=\sqrt{116}\\r=d/2=\frac{\sqrt{116}}{2}

We can then find the center of the circle by averaging the coordinates:

\frac{1+(-3)}{2}=-1

\frac{-4+6}{2}=1

Then, we substitute these values into the equation of a circle:

(x-(-1))^2+(y-1)^2=(\frac{\sqrt{116}}{2})^2\\(x+1)^2+(y-1)^2=58
