2 inch per min
Positive slope implies increase
<h3>Given system :</h3>
<h3>Solution to the system :</h3>
Substitute the given value of y into the equation -3x-2y=-12
Distribute -2 through the parentheses
Collect like terms
Move the constant to the right-hand side and change its sign
Calculate the sum and divide both sides of equation by -13
Now, Substitute the given value of x into y=5x-7
Multiply the numbers
Subtract the numbers
The possible solution of the system is the ordered pair (x,y)
Answer:
x < -24(option
Step-by-step explanation:
-¼x - 12 > -6
Add 12 to both sides
-¼x - 12+12 > -6+12
-¼x > 6
Divide both sides by -¼
x < 6 ÷ -¼
Please note that the inequality sign changes when divided by negative (minus). This is a rule in inequalities.
x < 6 × -4
x < -24
