Answer:
divide 5 on both sidesStep-by-step explanation:
add -61 on both sides:
5x - 61 + 61 = 20 + 61
simplify
5x = 81
divide 5 on both sides:
5x = 81

*BRAINLIEST* The graphs below have the same shape. Complete the equation of the blue graph.
Answer:
(x-2)^2
Step-by-step explanation:
The blue graph is shifted two units to the right of the "original" function x^2 (red). Let's recall the vertex form of a quadratic:
a (x-h)^2 + k
where a represents a constant that describes the opening of the parabola (up/down); h represents horizontal shift; and k represents vertical shift.
The blue graph is two units to the right (+2), there is NO vertical shift and NO change in how the parabola opens.
So, let's plug the appropriate values into vertex form:
(x-(+2))^2
= (x-2)^2

Suppose that a firm invests $5 million in the development of a new product that generates only about $250,000 in revenue after a full year on the market. The firm only has a patent for one year and other firms are likely to start producing similar products. Which of the following is the most rational decision for the firm to make?
Complete Question
The complete question is shown on the first uploaded image
Answer:
The correct option is C
Step-by-step explanation:
The correct option is
The firm should forget the new product, accept the loss of the investment and work on innovations that show signs of being more profitable.
The reason for this is that the period that the company is to recover the funds allocated to R &D is over i.e the patent(which is one of the most via way to recover their funds only last for one year so investing more resource on the product will lead to more loss for the company instead of a gain

The shaded area on the grid represents the part of the rectangular wall that was painted. Each small square on the wall has the same dimensions. Which percentage of the wall was painted?
The correct answer is 60%
Explanation:
A percentage represents a proportion of a total or 100% by using a number from 1 to 100. In this context, the first step is to count how many squares there are and how many were painted. This leads to the following results:
40 squares in total
24 painted squares
Knowing these two details it is possible to calculate the percentage. Follow this process:
- Write the values
40 squares = 100 % or total
24 squares = x (the value that needs to be found)
- Cross multiply to create an equation and solve this equation
40 x = 2400
x = 2400 ÷ 40
x = 60
The percentage that was painted was 60%
Find the uncertainty in a calculated average speed from the measurements of distance and time. Average speed depends on distance and time according to this function v(t,x) = x/t. Your measured distance and time have the following values and uncertainties x = 6.1 meters, 2.3 meters and t = 6.3 seconds and 1.5 seconds. What is the uncertainty in the average speed, ? Units are not needed in your answer.
Answer:
The uncertainty in the average speed is 0.134 meters per second.
Step-by-step explanation:
Let be [tex]v(t, x) =\frac{x}{t}[/tex] the average speed function, we calculate the uncertainty in the average speed by total differentials, which is in this case:
[tex]\Delta v = \frac{\partial v}{\partial x}\cdot \Delta x+\frac{\partial v}{\partial t}\cdot \Delta t[/tex]
Where:
[tex]\Delta v[/tex] - Uncertainty in the average speed, measured in meters per second.
[tex]\frac{\partial v}{\partial x}[/tex] - Partial derivative of the average speed function with respect to distance, measured in [tex]s^{-1}[/tex].
[tex]\frac{\partial v}{\partial t}[/tex] - Partial derivative of the average speed function with respect to time, measured in meters per square second.
[tex]\Delta x[/tex] - Uncertainty in distance, measured in meters.
[tex]\Delta t[/tex] - Uncertainty in time, measured in seconds.
Partial derivatives are, respectively:
[tex]\frac{\partial v}{\partial x} = \frac{1}{t}[/tex], [tex]\frac{\partial v}{\partial t} = - \frac{x}{t^{2}}[/tex]
Then, the total differential expression is expanded as:
[tex]\Delta v = \frac{\Delta x}{t}-\frac{x\cdot \Delta t}{t^{2}}[/tex]
If we get that [tex]\Delta x = 2.3\,m[/tex], [tex]t = 6.3\,s[/tex], [tex]x = 6.1\,m[/tex] and [tex]\Delta t = 1.5\,s[/tex], the uncertainty in the average speed is:
[tex]\Delta v = \frac{2.3\,m}{6.3\,m}-\frac{(6.1\,m)\cdot (1.5\,s)}{(6.3\,s)^{2}}[/tex]
[tex]\Delta v = 0.134\,\frac{m}{s}[/tex]
The uncertainty in the average speed is 0.134 meters per second.

How can you tell when to multiply and make boxes vs to simply combine like terms?
You can multiply ANYTHING. Just make sure that when you multiply, you change the exponents properly. Combining like terms is basically like normal addition. For example, you cannot add 6x +3y because they have different variables. If it was 3x+6x, then you can add it because they are like terms.

Which fraction is greater than the fraction represented by the model?
1/4
7/16
1/8
3/16
Answer:
7/16
Step-by-step explanation:
If it's easier to visualize, we can convert every into 1/16 including the graph to compare.
To convert the graph (currently in 1/8), we divide each segment to produce 16 segments, 6 of which are shaded (6/16 = 3/8).
The other fractions converted to 1/16 are as follows:
1/4 --> 4/16
7/16 --> 7/16
1/8 --> 1/16
3/16 --> 3/16
Now it's easy to tell which fraction is greater than the area represented in the model!

6 more than the product of 5 and a number.
Consider the expressions 5 + 8k and 8k + 5. Determine why the expressions are equivalent.
Using k = 3 5 + 8k 8k + 5 5 + 8(3) 8(3) + 5 5 + 24 = 29 24 + 5 = 29
Using k = 5 5 + 8k 8k + 5 5 + 8(5) 8(5) + 5 5 + 40 = 45 40 + 5 = 45
Complete the statements.
If both expressions have the same value after substituting and simplifying two different values for the variable, then they are.
The value of both expressions when k = 3 is and when k = 5 is 45, so the expressions are.
Answer:
First is equivalent then 29 last equivalent
Step-by-step explanation:
If both expressions have the same value, then they are equal to each other.
What is an equivalent expression?The equivalent is the expressions that are in different forms but are equal to the same value.
Consider the expressions 5 + 8k and 8k + 5.
Using k = 3
5 + 8k = 8k + 5
5 + 8(3) = 8(3) + 5
5 + 24 = 24 + 5
29 = 29
Using k = 5
5 + 8k = 8k + 5
5 + 8(5) = 8(5) + 5
5 + 40 = 40 + 5
45 = 45
If both expressions have the same value after substituting and simplifying two different values for the variable, then they are equal to each other.

If you're using PLATO this is the correct answer I just did the problem myself
I'll even explain below and drop the image screenshot
The equation x2 − 36 can be factored into (x − 6)(x + 6) using the difference of two squares.
The equation 9x2 − 1 is the difference of two squares, (3x)2 – 12, so it factors into (3x − 1)(3x + 1).
We can factor 4 out of the expression 4x2 − 16 to get 4(x + 2)(x − 2).

: A consumer electronics company has observed that 36 percent of their customers purchased a plasma screen television, that 26 percent of their customers purchases a DVR, and 12 percent of their customers purchased both a plasma screen TV and a DVR. Find the probability that a randomly chosen customer either purchases a plasma screen TV or a DVR.
Answer:
The probability that a randomly chosen customer either purchases a plasma screen TV or a DVR is 0.50 or as a percentage 50%.
Step-by-step explanation:
A consumer electronics company has observed that 36 percent of their customers purchased a plasma screen television, that 26 percent of their customers purchases a DVR, and 12 percent of their customers purchased both a plasma screen TV and a DVR. Find the probability that a randomly chosen customer either purchases a plasma screen TV or a DVR.
We have two elements in this set
Customers that purchase a plasma Screen ( S)
Customers that purchase a DVR (D)
From the question:
Customers that purchased a plasma screen television (P) = 36% = 0.36
Customers that purchased a DVR (D)= 26% = 0.26
Customers that purchased a plasma screen television and a DVR = ( S ∩ D) 12% = 0.12
Customers that purchased a plasma screen television = ( S ∪ D)
P ( S ∪ D) = P(S ) + P( D) - P ( S ∩ D)
P ( S ∪ D) = 0.36 +0.26 - 0.12
= 0.62 - 0.12
= 0.50
Converting to percentage = 0.50 × 100 = 50%
Therefore, the probability that a randomly chosen customer either purchases a plasma screen TV or a DVR is 0.50 or as a percentage 50%

Answer:
[tex]x=\frac{23}{6}[/tex] or [tex]4.6[/tex]
Step-by-step explanation:
[tex]3x + 2x + 7 = 10x - 16[/tex]
[tex]5x+7=10x-16[/tex]
Subtract 7 from both sides:
[tex]5x+7-7=10x-16-7\\5x=10x-23[/tex]
