Answer:
we have two solution x = 5 and x = 11
but in given problem x = 5 and x = –11
thus, only one of his solution x = 5 is correct
Step-by-step explanation:
Given
–2|8 – x| – 6 = –12
adding 6 both sides
–2|8 – x| – 6 +6= –12 +6
–2|8 – x| = –6
dividing both side by -2
–2|8 – x| /-2 = –6/-2
=>|8 – x| = 3
we know that
in modulus function |Y| = -y or y
Thus
|8 – x| = 3
can be written as
8-x = 3 or 8- x = -3
8-x-3 = 0 or 8-x+3 = 0
5-x = 0 or 11 -x = 0
x = 5 or x = 11
thus, we have two solution x = 5 and x = 11
but in given problem x = 5 and x = –11
thus, only one of his solution x = 5 is correct
Answer:
The last one letter D. is the answer
Answer:b
Step-by-step explanation:
Step 1 :
x
Simplify —
4
Equation at the end of step 1 :
x
— - -8 ≥ 0
4
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 4 as the denominator :
-8 -8 • 4
-8 = —— = ——————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
x - (-8 • 4) x + 32
———————————— = ——————
4 4
Equation at the end of step 2 :
x + 32
—————— ≥ 0
4
Step 3 :
3.1 Multiply both sides by 4
Solve Basic Inequality :
3.2 Subtract 32 from both sides
x ≥ -32
Inequality Plot :
3.3 Inequality plot for
0.250 x + 8.000 ≥ 0
One solution was found :
x ≥ -32
