Answer:
<h2>For c = 5 → two solutions</h2><h2>For c = -10 → no solutions</h2>
Step-by-step explanation:
We know

for any real value of <em>a</em>.
|a| = b > 0 - <em>two solutions: </em>a = b or a = -b
|a| = 0 - <em>one solution: a = 0</em>
|a| = b < 0 - <em>no solution</em>
<em />
|x + 6| - 4 = c
for c = 5:
|x + 6| - 4 = 5 <em>add 4 to both sides</em>
|x + 6| = 9 > 0 <em>TWO SOLUTIONS</em>
for c = -10
|x + 6| - 4 = -10 <em>add 4 to both sides</em>
|x + 6| = -6 < 0 <em>NO SOLUTIONS</em>
<em></em>
Calculate the solutions for c = 5:
|x + 6| = 9 ⇔ x + 6 = 9 or x + 6 = -9 <em>subtract 6 from both sides</em>
x = 3 or x = -15
Answer:

Answer:
31/2
Step-by-step explanation:
Answer:
C:
or 
Step-by-step explanation:
To solve the equation
we need to factor it
We are looking for two numbers that when multiplied give -12 and when added give -x
This means that when factored, the equation would be 
Now we can set each of these equal to 0, which means that at
and
, the equation will equal 0
Answer:
x= 9 y=2
Step-by-step explanation:
Add up the equations vertically to eliminate y.
-x=-9
change the signs:
x=9
substitute the given value of x into the equation 2x-4y=10
2(9)-4y=10
18-4y=10
4y=8
y=2
