What is the result of subtracting the second equation from the first? -2x+y=0 - 7x + 3y = 2

Mathematics
1 answer:
artcher [175]3 years ago
6 0

Answer:

5x - 2y = - 2

Step-by-step explanation:

Given the 2 equations

- 2x + y = 0 → (1)

- 7x + 3y = 2 → (2)

Subtracting (2) from (1) term by term

- 2x - (- 7x) + y - 3y = 0 - 2, that is

- 2x + 7x - 2y = - 2

5x - 2y = - 2

What are the possible values of remainder r, when a positive integer 'a' is divided by 3​
fredd [130]

Answer:

0, 1, 2

Step-by-step explanation:

Euclid's division Lemma states that for any two positive integers ‘a’ and ‘b’ there exist two unique whole numbers ‘q’ and ‘r’ such that , a = bq + r, where 0≤ r < b.

Here, a= Dividend, b= Divisor, q= quotient and r = Remainder.

According to Euclid's division lemma a 3q+r, where 0≤r≤3 and r is an integer.

Therefore, the values of r can be 0, 1 or 2.

bekas [8.4K]
<span>75 lbs of Earl Grey 225 lbs of Orange Pekoe Some definitions. E = number of pounds of Earl Grey (300-E) = number of pounds of Orange Pekoe Expression for selling price of new blend P=300*4.5 "there is to be no difference in revenue from selling the new blend versus selling the other types." so P = 6E + 4(300-E) Set them equal to each other, then solve for E 300*4.5 = 6E + 4(300-E) 1350 = 6E + 1200 - 4E 150 = 6E - 4E 150 = 2E 75 = E So 75 lbs of Earl Grey was used and 300-75 = 225 lbs of Orange Pekoe</span>

The diagram represents a triangle that is reduced by a scale factor of 0.4.
NARA [144]

Answer:the answer would be 8.

Step-by-step explanation:

If you look at the reduced triangle, the height is 2. Therefore you would have to multiply by 4 instead of 0.4 even if the scale factor is 0.4. The reason is, you are enlarging the triangle to find the bigger triangle. If you did 0.4 times 2 you would get 0.8. But that wouldn’t make any sense if you said that that was the height of the ENLARGED triangle.

Steven is playing an online video game
astraxan [27]
Steven gained 100 points.

To calculate the gain or lose of any 2 numbers, always do

Final - Initial

So,

-50 - -150

Is like saying

I have negative 50, and I take away negative 150.

Taking away negative numbers is just addition.

-50 + 150 = 100
