WILL MARK BRAINLIEST!The multipliers of this system of equations have been determined to create opposite terms of the y-variable.

4 (one-fourth x minus three-fourths y = 34) right-arrow x minus 3 y = 136
24 (three-fourths x + one-eighth y = negative 12) right-arrow 18 x + 3 y = negative 288

Answer 1

Answer:

Answer:

thus, x=-34 and y=170/-3

Step-by-step explanation:

4((1/4)*x-(3/4)*y)=34

x-3y=136

24((3/4)*x+(1/8)*y)=12

18x+3y=-288

4x-3y=34⇒x-3y=136

18x+3y=12⇒18x+3y=-288

lets solve 4x-3y=34⇒x-3y=136 first:

4x-3y=34

x-3y=136

4x-3y=34

-x+3y=-136

3x=-102

x=-102/3

x=-34

lets plug in x to one of the equations, since both equations are equal to each other:

4x-3y=34

4(-34)-3y=34

-136-3y=34

-3y=170

y=170/-3

now lets solve: 18x+3y=12⇒18x+3y=-288

18x+3y=12

18x+3y=-288

18x+3y=12

-18x-3y=288

0 $\neq$ 300

so, this system doesn't work

thus, x=-34 and y=170/-3

Value of the expression. ? 18-2x(4+3)

Answers

18 - 2x(4+3) =

combine like terms in the parentheses

18 - 2x(7) =

Multiply

18 - 14x (This is the value of the expression)

We can solve for x by setting it equal to zero

18 - 14x = 0
-14x = -18
x = -18/-14
x = 1 2/7

The answer to the expression is 4

Which equation involves a prime quadratic and cannot be solved by factoring? A. x2 + 5x − 4 = 0 B. x2 − x − 6 = 0 C. x2 + 3x − 4 = 0 D. x2 + 6x + 9 = 0 Reset

Answers

Answer:

Option A

Step-by-step explanation:

We can try to factorize all the options one by one.

For A:

$x^(2) +5x-4\n=> x^(2)+4x+x-4\n=>x(x+4)+1(x-4)$

We can see that the quadratic expression cannot be solved by factorization as the factors at the end of factorization are not equal in both brackets. So Option A is the correct answer for the given question.

Moreover we can also note that all the other quadratic expressions can be factorized ..

Answers

16/24 = 8/12 = 4/6 = 2/3

We can divide 16 and 24 by 2 so we can simplify to 8/12 and we can do it again and get 4/6 and again to get 2/3. We can no longer simplify so that is the simplified answer.
