Answer: #4 C   Domain is x such that x is greater than -1 (all real numbers greater than -1)

#5 B  Points C, F & G

Step-by-step explanation: Look at the coordinate of the vertex. It is at (-1, 1)  so the -1 is the lowest number in the Domain (running left to right). The attows at the right ends mean that the lines go to infinity. The symbol ∈ means "belongs to" the R (special font not available here) means "all real numbers.

The y-value, 1 is not relevant here, as the Range (up and down, like a mountain range) is infinity, and the arrows keep going forever. ∈R  means all real numbers.

For the Triangle: First ,imagine a box with the boundaries matching the domain and range given, so the left side is at -2, the right side is at 6 [Domain] and the  top and bottom are at 5 and -1 [Range]

Pick the points that are on the boundary lines.  C is at (6,3) on the right boundary, F is at (2,-1) on the bottom boundary and G is at (-2,5) at the corner where the top and left sides meet.

Which equation is a reasonable description of the least-squares regression line for the Predicted Rotten Tomatoes Score?
forsale [732]

Answer:

Predicted Rotten Tomatoes Score = 29.476 + 1.201 * Metascore

Step-by-step explanation:

The image is needed to solve it, I found an image that I think would be the one that adapts to the exercise, which I will attach.

The answer is:

Predicted Rotten Tomatoes Score = 29,476 + 1,201 * Metascore

Because if we follow the red line, we can see that it impacts with the axis of the and a little lower than 30, that is to say that when Metascore is 0, the value must be close to 30 and in this case the only value close to 30 inside the answer is 29,476, so this is the answer.

Your company is hosting a benefit 5 kilometer race How long will the race be to the nearest tenth of a mile?
8090 [49]
In this question the main part is to convert the kilometer to miles and then writing the answer to the nearest tenth of a mile. the information given in the question is that the race is for a distance of 5 kilometers.
Now we already know
1 km = 0.6214 mile
Then
5 km = ( 0.6214 * 5) miles
         = 3.107 miles
         = 3.11 miles
So the actual distance when converted to miles will be 3.11 miles. I hope this is the answer you were looking for. This is the simplest way for doing such problems and in future you can follow this method to find the answers without the need of any help.

brand a has recognition value of $47 more than brand b . if the total value of these two brands are $113 million , find the valu
Serga [27]
So a-47=b
so total value =113 times 1,000,000=113,000,000=a+b
subtitute a-47=b into equation

a+a-47=113,000,000
add 47 to both sides
2a=113,000,047
divide both sides by 2
$56,500,023.5=a or <u>roughly</u> 56.5 million

a-47=b
56,500,032.5-47=b
56,499,976.5=b

so 56,500,023.5=a
56,499,976.5=b
