4y + x = 4 . . . . . . . (1)
2y - x = 8 . . . . . . . (2)

(1) + (2) => 6y = 12
y = 12/6 = 2

From (2), 2(2) - x = 8
4 - x = 8
x = 4 - 8 = -4

Therefore solution is (-4, 2) and lies on both lines.

Ab+bc=<br> this is adding of like terms

stellarik [79]

Answer:

(a+c)b OR it's already on simplified form

Step-by-step explanation:

depending upon what your instructor wants, they may want you to say it's already simplified (which happens sometimes).

HOWEVER, if you know how to factorize (which is essentially un-distributing), you could factor out the b which is common in both.

$ab + bc \\ = b( \frac{ab}{b} + \frac{bc}{b} ) \\ = b(a + c)$

Check all of the points that are solutions to the system of inequalities.

Setler [38]

Answer:

C and F

Step-by-step explanation:

To be a solution of the inequality, we just plug in the point into the original system. For example, let's look at A. Let's plug in x = 1 and y = 1. We get 1 ≤ 5 + 4 and 1 > -3 + 4. These simplify to 1 ≤ 9 and 1 > 1. Since 1 > 1 is a false statement, A is not a solution. Following this process, we get:

A: Not a solution

B: Not a solution

C: Solution

D: Not a solution

E: Not a solution

F: Solution
