The solution is: x=2, y=-2
Step-by-step explanation:
Given equations are:
6x+2y=8 Eqn 1
12x+y=22 Eqn 2
Multiplying Eqn 1 by 2
Eqn 3
Subtracting Equation 2 from eqn 3

Putting y=-2 in eqn 2

The solution is: x=2, y=-2

Answer:
See below in bold.
Step-by-step explanation:
f(x)=-2|x|-3
To get f(-3) we substitute -3 for x
= -2|-3| - 3 <--- Note |-3| means the absolute value of -3 which is 3.
= -2*3 - 3
= - 9.
-2 f(x) = -2 * (-2|x| - 3)
= 4|x| + 6.
The answer would be 7.81, or about 8 units if you estimate
Answer:
Step-by-step explanation:
<u>Unknown value is q.</u>
<u>Solve for the unknown value:</u>
- 6 + q = 25 1/2
- q = 25 1/2 - 6
- 25 1/2 - 6
- = 19 1/2.
- q = 19 1/2.
<h2>
Answer is q = 19 1/2.</h2>
