How would I solve the equations: y = x-4 and y=x^2-4x using substitution
andriy [413]

Answer:

x = 6

Explanation:

y = x - 4

26 = 4x + y


If y = y, then we can rewrite this system as this: 4x + x - 4 = 26


Then we combine like terms and add 4  on both sides to give us  5  x  =  30 . Divide by 5 on both sides and we arrive at the solution: x = 6

Factor 2k^2 - k - 3<br> A: (2k-3)(k+1)<br> B: (k-1)(2k+3)<br> C: (2k-1)(k+3)<br> D: (k-3)(2k+1)
Art [367]

Answer:

A

Step-by-step explanation:

Given

2k² - k - 3

Consider the factors of the product of the k² term and the constant term which sum to give the coefficient of the k- term.

product = 2 × - 3 = - 6 and sum = - 1

The factors are + 2 and - 3

Use these factors to split the k- term

2k² + 2k - 3k - 3 ( factor the first/second and third/fourth terms )

= 2k(k + 1) - 3(k + 1) ← factor out (k + 1) from each term

= (2k - 3)(k + 1) → A
