Y=3x-2 y-2=x what is the soultions between the two equations

Mathematics
1 answer:
svet-max [94.6K]3 years ago
8 0

Answer:

(2, 4)

Step-by-step explanation:

"What is the solution of this system of equations?"

Substitute 3x - 2 for y in the second equation, obtaining:

3x - 2 - 2 = x

Consolidate like terms:  subtract x from both sides and add 4 to both sides:

2x = 4.  Thus, x = 2.  Substituting 2 for x in the first equation, we get:

y = 3(2) -2 = 4.

Thus, the solution is (2, 4)

Triangle XYZ has been enlarged and P as the center of dilation and scale to form a triangle X’ Y’ Z’
Maksim231197 [3]

Distances from the center of dilation are multiplied by the dilation factor. The appropriate choice is ...

... A. X'P/XP = Y'P/YP = Z'P/ZP

_____

We don't know what selection B means in this context.

Selection C will only be true if the dilation is by a factor of 2.

Selection D will only be true if P is the center of the circumscribing circle for both X'Y'Z' and XYZ.

a jar contains 36 marbles. it has 20 red, 12 black, and 4 green marbles. two marbles are drawn; the first is not returned before
Sedaia [141]
The probability of drawing red on the first draw is 20/36. Having drawn red on the first draw, the probability of drawing red on the second draw is 19/35. The probability that both marbles are red is therefore;
P(both\ red)=\frac{20\times19}{36\times35}=0.302

How many ways can six friends be arranged around a circular dinner table?
Mice21 [21]
A question such as this one is a little tricky since the people seated are not in a straight line. 

For a circular table seating question, (n-1)! formula is used. Without restrictions 5! people can be seated. 

You might be wondering why it is not 6!, this is because the first person will the the 6 person so you are accounting for the same person twice. 

Hope I helped :)

Perbandingan kelereng Faiz dan Bayu 4 : 11. Jumlah kelereng mereka 60 buah. Selisih kelereng keduanya adalah
stepladder [879]

Answer:

Perbedaan jumlah kelereng atau 28 kelereng

Step-by-step explanation:

Dalam pertanyaan ini, kami memiliki dua orang yang memiliki jumlah kelereng yang berbeda. Kita tidak tahu jumlah masing-masing individu tetapi kita tahu rasio dan total. kami bertugas menemukan perbedaan jumlah kelereng yang dimiliki oleh masing-masing individu.

Untuk melakukan ini, pertama-tama kita tambahkan rasio mereka.

Ini memberi 4 + 11 = 15

Mari kita hitung pembagian Faiz, yaitu 4/15 * 60 = 16 kelereng

Bayu share adalah 11/15 * 60 = 44 kelereng.

Kami sekarang melanjutkan untuk menemukan perbedaan dalam jumlah kelereng yang dimiliki oleh keduanya.

Itu akan menjadi 44-16 = 28 kelereng
