Answer:

Option A) Inconsistent is correct

Step-by-step explanation:

Given equations are y=5x+2\hfill (1)

and 10x-2y=12\hfill (2)

Rewritting the equation y=5x+2 as below

5x-y=-2

Now multiplying the above equation into 2 we get

10x-2y=-4\hfill (3)

Now subtracting the equations (2) and (3)

10x-2y=12

10x-2y=-4

________

0\neq 16

Therefore the given system of equations has no solution

Therefore it is inconsistent

Therefore given two lines are parallel. Two parallel lines never intersect, so the given system has no solution and is inconsistent.

Option A) Inconsistent is correct

What are the solutions of x^2-2x+10=0
saw5 [17]

There are a few ways to solve this, the simplest of which is probably factoring. Start by finding factors of C (10) that add up to be B (-2).


fac(10) { -10, 1 ; -5, 2 }


Well, there are no factors of 10 that can add to b - so we will use the quadratic formula.


(-b +- sqrt(b^2 - 4ac)) / 2a

where a = 1, b = -2, c = 10


b^2 - 4ac = (-2)^2 - 4(1)(10) = 4 - 40 = -36

-b +- sqrt(-36) / 2a

(2 +- sqrt(-36)) / 2


sqrt(-36)

sqrt(-1 * 36)

sqrt(-1) * sqrt(36)

i * 6

6i


2 + 6i / 2 ; 1 + 3i

2 - 6i / 2 ; 1 - 3i


Solutions: 1 + 3i, 1 - 3i

Maria adopted for dogs altogether they ate 1 3/4 pound of food each day 1 pound is equal to 16 ounces how many ounces of food wi
olga55 [171]

Answer:

65 ounces

Step-by-step explanation:

Number of dogs = 4

Each day, they ate 13/4 pounds of food

1 pound = 16 ounces

If 4 dogs eat 13/4 pounds of food

1 dog will eat x pounds of food

1 dog will eat = (1 * 13/4) / 4 = 13 /16

1 dog will eat 13 / 16 pounds of food each day.

1 pound = 16 ounces

13 / 16 pounds = y ounces

y = (13/16 * 16) / 1

y = 13 ounces

Each dog eats 13 ounces of food daily.

In five days, each dog will eat 13 * 5 = 65 ounces of food.
