Answer:
x > -6
Step-by-step explanation:
Here in this question, we have to solve for x from the given inequality
-6 > -30- 4x.
We can solve the inequality equation by using the properties of inequality.
We have, -6 > -30 -4x
⇒ -6+30 > -4x
{The summation and subtraction rules of the inequality equation is similar to that of ordinary equations}
⇒24 > -4x
Dividing both sides by -1, we get,
⇒-24 < 4x
{In case of division of both the sides of an inequality by a negative number, the inequality sign changes from > to < and vice-versa}
⇒4x > -24
Dividing both the sides by 4, we get
⇒ x > -6 {There is same rule as equality equation for division both sides by a positive number} (Answer)
Answer:
3
Step-by-step explanation:
The perimeter of the rectangle is equal to the doubled sum of the sides, and the area is equal to the product of the sides. So we have the following equation
The correct answers are:
______________________________________________________
[B]: " (3, -3) " ; AND:
______________________________________________________
[C]: " (-2, -3) " .
______________________________________________________
<u>
Note</u>: Any point with the "y-coordinate" of "-3" would also be on the line.
As such, the correct answers, are:
______________________________________________________
[B]: " (3, -3) " ; AND:
______________________________________________________
[C]: " (-2, -3) " .

Answer: (7,5) X=7 and Y=5
Explanation:
Add the two equations together to eliminate y from the system.
x-y=2 + x+y=12
= 2x = 14
Divide both sides by 2
x=7
Substitute the value found for x into one of the original equations to solve for y
(7)-y=2
Move all terms to one side to make it easier
-y=2-7
Subtract
y=5
