Combine like terms in each expression

2. -4b + 2w + (-4b) + 8w
3. 6- 5z + 8 - 4z + 1
Answers
Answer:
5/12k = 29/36m
8b = 10w
9z = 15
Step-by-step explanation:
Combining the like terms in these sets of equations is quite easy and straightforward. All we do is carry the like terms to either of the side of the equation, and question is solved. As in below
1/4k + 1/4m - 2/3k + 5/9m =
1/4k - 2/3k + 1/4m + 5/9m = 0
-5/12k + 29/36m = 0
5/12k = 29/36m
-4b + 2w + (-4b) + 8w =
-4b - 4b + 2w + 8w = 0
-8b + 10w = 0
8b = 10w
6- 5z + 8 - 4z + 1 =
6 + 8 + 1 - 5z - 4z = 0
15 - 9z = 0
9z = 15

Let f(x)=x−1. The graph of g(x)=f(x)+k is shown below. Identify the value of k.
Answers
Explanation:
The linear equation f(x) = x-1 has the y intercept -1. We can see this by comparing it to y = mx+b and see that b = -1. Or we could plug in x = 0 to get the output y = -1.
The graph shows the y intercept is y = 3. The jump from y = -1 to y = 3 is plus 4. This means the graph of f(x) has been moved up 4 units. Therefore, k = 4.
Since y = f(x), saying g(x) = f(x)+k = f(x)+4 means we add 4 onto each y value. This indicates every point on the f(x) line moves up 4 units to arrive at a corresponding point on the g(x) line.

what is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Let w = the number of weeks.
Let d = the number of dollars April pays the service.
April pays a dog-walking service $30 each week to walk her dog.
So, the equation represents the situation
d= 30 x w
Hence, the amount in dollar for w weeks be d= 30 x w.

What is the equation, in point-slope form, of the line
that is parallel to the given line and passes through the
point (4, 1)?
Answers
Answer:
Step-by-step explanation:
Given:
The line parallel to the given line containing the points (-3,3) and (-2,1).
Also, the parallel line passes through the point (4,1).
We need to determine the equation of the line in slope - intercept form.
Slope:
Since, the two lines are parallel, then their slopes are equal.
Thus, the slope of the parallel line can be determined using the formula,
Substituting the points (-3,3) and (-2,1), we get;
Thus, the slope of the line is
Equation of the line:
The equation of the line can be determined using the formula,
Since, the line passes through the point (4,1), let us substitute the point (4,1) in the above formula, we have;
Thus, the equation of the line is
Hence, y − 1 = −2(x − 4) is the correct answer.

An object moves along a straight line so that at any time t , for 0≤t≤8 , its position is given by x(t)=5+4t−t2 . For what value of t is the object at rest?
A. t = 2
B. t = 4
C. t = 9/2
D. t = 5
Answers
Answer:
D. t = 5
when the object is at rest => x(t) = 0
<=> -t^2 + 4t + 5 = 0
<=> t^2 - 4t - 5 = 0
<=> (t - 5)(t + 1) = 0
=> t = 5 or t = -1
but t》0
=> t = 5
The value of t if the object at rest is 2 secs: Option A is correct
Given the position of the object moving in a straight line expressed as:
x(t)=5+4t−t²
The velocity of the body at rest is zero
Get the velocity fucntion.
v(t) = d(x(t))/dt = 4 - 2t
Since v(t) = 0
0 = 4 - 2t
-4 = -2t
t = 2
Hence the value of t if the object at rest is 2 secs

Answer:
First option at second row , Option( C )
Step-by-step explanation:
In order to solve the problem,
First we need to arrange the numbers in ascending order.
4 , 7 , 8 , 10 , 11 , 13 , 15 , 15 , 22 , 28
Median = [tex]\frac{11 + 13}{2}[/tex]
= 12
From the first range ( 4,7,8,10,11 ) , we can find Q1 also known as first quartile where Q1 = 8 ( middle-most number).
Similarly, from the second range ( 13,15,15,22,28 ) , we can find Q2 also known as third quartile where Q3 = 15 (middle-most number ).
Now, for the box plot,
We need to draw a number line from 0 to 32.
Next, we need to draw a box from Q1 to Q3 with a vertical line through the median.
Next, we put dots above 4 and 28 since our numbers start from 4 and end with 28.
Finally we join the dots and the box plot with a straight line.
Hence, option C is the correct choice.

28. An Amazon Echo originally costs $99.99. It is on sale for 10% off. Sales tax of 7.5% is then added to the sale price. What is the cost of the Echo on sale including tax? Round your answer to the nearest penny.
Answers
Answer:
$96.74
Step-by-step explanation:
The original cost of the Amazon echo = $99.99
Then we have a 10% sale which we are going to subtract from the original cost.
= $99.99-(99.99x10%)
= 99.99-9.999
= $89.991
Then a tax of 7.5% was added
= $89.991 + (89.991 x 7.5%)
= 89.991 + 6.749325
= $96.740325
Therefore the cost of the echo including tax is $96.74

A:One Solution
Step-by-step explanation:
First substitute the y in the first equation with the second equation to get
-2x-4=3x+3
since theres a variable of both sides, you subtract the variable with the least coefficient, in this case, you add 2x to both sides to get
-4=5x+3
subtract the constant on both sides to get
