Which classification describes the system of linear equations?

Mathematics
1 answer:
salantis [7]3 years ago
4 0

Answer:

Inconsistent

Step-by-step explanation:

Consistent independent means that there is only one solution; ie one place where the 2 lines intersect.

Inconsistent means that the lines will NEVER cross because they are parallel

Consistent dependent means that the 2 lines, when solved for y, are the exact same line (same slope, same y-intercept)

In our system, one of the equations is already solved for y, so let's solve the other one for y:

x-2y=1 so

-2y=-x+1 and

y=\frac{1}{2}x-\frac{1}{2}

The slopes of the 2 lines are the same; therefore, they are parallel and will never intersect.  Inconsistent system.

Herald was making a recipe that needs 1/2 cup of vegetable oil and 1/8 cup of olive oil. How much oil does it need in all?
zaharov [31]

Answer:

\frac{5}{8} of oil.

Step-by-step explanation:

Firstly, you need to find the LCD (lowest common denominator), this can be done by factoring the denominators and knowing the multiples.

In this case, you can see that 2 is a factor of 8 so we can simply multiply \frac{1}{2} so that the denominator is 8:

8 ÷ 2 = 4

\frac{1 * 4}{2 * 4} = \frac{4}{8}

Now the fractions can be added easily:

\frac{4}{8} + \frac{1}{8} = \frac{4 + 1}{8}

= \frac{5}{8} of oil.

Hope this helps!

X+y=4 and 2x+3y=2 then find x and y​
Sladkaya [172]

Answer:

x=10, y=-6

Step-by-step explanation:

1) express x from the first equation x+y=4 x=4-y

2) It is the system of equations, so both equations are simultaneous.

you can replace x to 4-y in the second one

2 *(4-y) +3y=2

8-2y+3y= 2

y=-6

x= 4-y=4-(-6)=10

The answer is x=10, y=-6
