Answer: b, 12
explanation: combine -3/2 * x and u get -3/2x. then isolate the variable by doing the inverse of subtraction on both sides. (add 9 on both sides). then do the inverse of multiplication on both sides. (divide by -3/2 on both sides)
Alicia received the following seven scores on her math assignments.
80, 90, 10, 75, 90, 95, 99
Find the mean and median. Which measure of center best represents the data?
Answers:
Mean = 77Median = 90The median is the better measure of center=============================================
Explanation:
Part (1) Finding the mean
Add up the values to get
80 + 90 + 10 + 75 + 90 + 95 + 99 = 539
Then divide by 7 because there are 7 values in this list
539/7 = 77
The mean is 77
--------------------------
Part (2) Finding the median
First we'll need to sort the values from smallest to largest
{80, 90, 10, 75, 90, 95, 99}
will sort to
{10, 75, 80, 90, 90, 95, 99}
The middle most value is 90 since we have three items below it {10,75,80} and three items above it {90, 95, 99}.
The median is 90
--------------------------
Part (3) Which is the better measure of center?
Nearly all of the values are clustered from 75 to 99. The value 10 is an outlier since it's far from the main cluster. There are more technical processes used to find out if 10 is actually an outlier or not, but we won't deal with that right now.
The much smaller outlier pulls on the mean to make it smaller than what it should be. The mean 77 is too small to represent what the center should be. The median is not affected by outliers, which is why it's used in applications such as home prices.
The median 90 is the better measure of center.

Water Street intersects 25th Street and 28th Street at right angle.Highway 47 is parallel to 28th StreetWhat to do?
How are 25th Street and Highway 47 related[tex]?[/tex]Step-wise-Step Explanation:
If wall Street intersects 25th Street and 28th Street at right angle then they will Parallel (||) to each other. Because,
If two lines are perpendicular to the third line then those two lines are parallel to each other as they will never meet.Now Highway 47 is parallel to 28th Street. It means 25th Street is also parallel to Highway 47 because,
If two lines are parallel to the third line then those two lines are parallel to each other as they will never meet.Thus, They are Highway 47 and 25th Street are parallel to each other. (Answer)

The third and last ones is not functions.
Answer:
The first, third, and second are functions and the fourth and fifth are not a function
Step-by-step explanation:
Function meaning all the numbers in the y column are different so for an example 123 but if the numbers were 212 there are multiply of one number so that would not be a function

What net force would be required to accelerate a truck at 10 m/s^2 that has a mass of 150 kg.
A fish is hovering at –320 feet in relation to sea level. Then it descends 2 feet per second for 8 seconds. Brenda says that the new position of the fish in relation to sea level is represented by the equation below. 2 times 8 + (negative 320) = 336 Which explains whether Brenda is correct? Brenda is correct because her answer represents 336 feet below sea level. Brenda is correct because Negative 16 + (negative 320) = 336. Brenda is not correct because the new position is 2 times 8 + (negative 320) = Negative 304. Brenda is not correct because the equation should be Negative 2 times 8 + (negative 320) = negative 336. ILL GIVE BRAINLIEST
Answer:
The answer is D or "Brenda is not correct because the equation should be Negative 2 times 8 + (negative 320) = negative 336"

Identify the domain of the function.
Replace the "?" with the correct value to identify the
range of the function.
St.
10
-10
Answer:
Domain: All real numbers
Range: y is greater than or equal to -5
Step-by-step explanation:
The domain is every possible x value. Because the function keeps going, it will be all real numbers.
The range is every possible y value. Because the function never goes below -5, y has to be greater than or equal to that.
Hope that helps! :D

An investment earn 6% simple interest. What amount of principal is need to have $3000 after 5 years
Answer:
The amount of $1000 principal is needed to have $3000 after 5 years.
Step-by-step explanation:
As the interest formula is
[tex]I=Prt[/tex]
Where
P is the principler is the rate in decimalt is the time in yearsSubstituting the following values in the interest formula and solve for P
I=$3000
r = 6% = 6/100 = [tex]0.06[/tex]
t = 5
so the equation becomes
[tex]I=Prt[/tex]
[tex]3000=P\left(0.06\right)\left(5\right)[/tex]
switch both sides
[tex]P\left(0.06\right)\left(5\right)=3000[/tex]
[tex]P\left(0.3\right)=3000[/tex]
[tex]P=10000[/tex] $
Therefore, the amount of $1000 principal is needed to have $3000 after 5 years.

You are making a poster to support your friend for homecoming. Your original photo is 4 inches by 6 inches. You want the photo on the poster to be 5 feet by 7.5 feet. What is the scale factor of this dilation? PLEASE HELP!!!!
The answer is 9.
We have been given that dimensions of original photo are 4 inches by 6 inches. We want the photo on the poster to be of dimensions 3 feet by 4 1/2 feet.
First of all we will convert dimensions of poster from feet to inches.
Now, let us compare sides of our original photo with corresponding sides of poster.
Now, let us compare the second pair of corresponding sides.
We have seen that sides of poster are 9 times the sides of our original photo, therefore, the scale factor of this dilation is 9.
