Answer:
infinite solutions
Step-by-step explanation:
y = 2x + 6
when x = 0, y = (2 x 0) + 6 = 6 ⇒ (0, 6)
when y = 0, 0 = 2x + 6 ⇒ x = 3 ⇒ (3, 0)
Plot the two points and draw a line through them
3y = 6x + 18
divide everything by 3 ⇒ y = 2x + 6
Therefore, y = 2x + 6 equals 3y = 6x + 18
So the lines overlap (produce the same graph)
Therefore, the system will have infinite solutions
Hello!
Answer:
1.
*The answer must have A NEGATIVE SIGN ONLY!*
2.
*The answer must have A POSITIVE SIGN ONLY!*
3.
*The answer must have a NEGATIVE SIGN ONLY!*
Step-by-step explanation:
1. 9w=-54
First, you divide by 9 both sides of an equation.
9w/9=-54/9
Simplify.
-54/9=-6
<u><em>W=-6 is the final answer.</em></u>
____________________________________
2. b-12=3
First you add by 12 both sides of an equation.
b-12+12=3+12
Add by the numbers from left/right.
3+12=15
<u><em>b=15 is the final answer.</em></u>
__________________________________________
3. n/4=-11
First you multiply by 4 both sides of an equation.
4n/4=4(-11)
Multiply by the numbers from left/right.
4*-11=-44
<u><em>n=-44 is the final answer.</em></u>

Answer:
(-3+) /2, (3+) / 2 which is approx -3.791 and 0.791
Step-by-step explanation:
i used the quadratic formula: [-b± sq rt (b² - 4ac) / 2a]
in this problem, a = 1, b = 3, and c = -3
