Answer:
y=0.5x-7
Step-by-step explanation:
x-2y=8
2y=x-8
y=0.5x-4 m1=0.5
m1=m2=0.5 - the slope for parallel lines are equaly
y=m2x+b
-6=0.5*2+b
b=-7
y=0.5x-7

Question : -6+(-6)+(-6)
4 meters 85 millimeters to milimeters.
Answer:
4085
Step-by-step explanation:
4 meters = 4000 millimeters + 85
= 4085
Answer:
By changing 4 meters 85 millimetres to milimetres we get 4085 milimetres
Step-by-step explanation:
In the first step change 4m to mm
We know that 1m = 1000mm
So, 4m = 4000mm
Now add 4000mm to 85mm
= 4000mm+85mm
= 4085mm

You offered a SALARY job of $47,603, and you are expected to work 44 hours a week
What would your hourly rate be?
Answer:
$20.81
Step-by-step explanation:
There are 52 weeks in a year.
Let's say you get paid x dollars per hour. Every week, you get paid x dollars for each hour you work. If you work 44 hours, you get paid x * 44 dollars a week. We get paid x * 44 dollars each week for a year, for 52 weeks. We can represent this as (x*44) * 52 = x * 2288. This is the amount you get paid each year. Setting that to your yearly salary of $47,603, we have
$47603 = x * 2288
divide both sides by 2288 to isolate x
x ≈ $20.81

The ratio of two numbers is 7:8 .If the first number is 84. Find the second number.
Answer: The second number is 96.
Step-by-step explanation:
Let the second number be x
7/8 = 84/x
or, 7x = 672
or, x = 672/7
so, x = 96
Answer: The second number = 96
Step-by-step explanation:
Given information
Ratio = 7 : 8
First number = 84
Second number = x
Set proportion according to the given information
84 / x = 7 / 8
Cross multiply
7x = 84 × 8
7x = 672
Divide 7 on both sides
7x / 7 = 672 / 7
[tex]\boxed{x=96}[/tex]

compound inequality for x.
8x 3/4
Answer:
There are generally 3 methods to solve inequalities
Step-by-step explanation:
By algebraic method
Example 1: Solve: 2x - 7 < x - 5
2x - x < 7 - 5
x < 2
By the number-line method.
Example 2. Solve

First, solve f(x) = 0. There are 2 real roots x1 = 1, and x2 = - 3.
Replace x = 0 into f(x). We find f(0) = - 3 < 0. Therefor, the origin O is located inside the solution set.
Answer by interval: (- 3, 1)
--------------------- - 3 ++++++++ 0 ++++ 1 ----------------

.
The graph of f(x) is an upward parabola (a > 0), that intersects the x-axis at x1 = 1 and x2 = - 3. Inside the interval (-3, 1), the parabola stays below the x-axis --> f(x) < 0.
Therefor, the solution set is the open interval (-3, 1)

Each number is two times three less than the previous number.
A sequence is the pattern or rule that guides the creation of a set. The most common sequence are the arithmetic and the geometric sequence.
A sequence that starts with 0 is: 0, -6, -12, -18.....A sequence that starts with 3 is: 3, -3, -9, -15.....The complete question illustrates that we build a sequence of number.
Let the n term of the sequence be [tex]T_n[/tex].
2 times 3 less than the previous number means:
[tex]T_n = T_{n-1} - 2 \times 3[/tex]
Where:
[tex]T_n \to[/tex] The current number
[tex]T_{n-1} \to[/tex] The previous number
Assume the first number starts with 0, the next numbers will be:
[tex]T_2 = 0 - 2 \times 3 = -6[/tex]
[tex]T_3 = -6 - 2 \times 3 = -12[/tex]
[tex]T_4 = -12 - 2 \times 3 = -18[/tex]
So, the sequence is:
0, -6, -12, -18.....
Assume the first number starts with 3, the next numbers will be:
[tex]T_2 = 3 - 2 \times 3 = -3[/tex]
[tex]T_3 = -3 - 2 \times 3 = -9[/tex]
[tex]T_4 = -9 - 2 \times 3 = -15[/tex]
So, the sequence is:
