The figure shows the graphs of the functions y = f(x) and y = g(x). The four indicated points all have integer coordinates. y = f(x) y = g(x) If g(x) = k f(x), what is the value of k? I am not sure how to do this. k = -3
Answers
Answer:
k = -3
Step-by-step explanation:
f(x) = -2x+1
g(x) = 6x - 3
=> g(x) = k.f(x)
6x - 3 = k(-2x+1)
k = (6x-3)/(-2x+1)
= 3(2x-1)/-1(2x-1)
k = 3/(-1) = -3
The value of k for the given function will be k = -3.
What is a function?In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. A function can be thought of as a machine that takes an input, performs a certain operation on it, and produces an output.
Formally, a function is defined as a set of ordered pairs (x, y) such that each value of x is associated with exactly one value of y. The set of all possible inputs to a function is called its domain, while the set of all possible outputs is called its range.
The given functions are,
f(x) = -2x+1
g(x) = 6x - 3
The value of k will be calculated as,
g(x) = k.f(x)
6x - 3 = k(-2x+1)
k = (6x-3)/(-2x+1)
k= 3(2x-1)/-1(2x-1)
k = 3/(-1) = -3

Find the measure of the missing angle.
Answer: a= ______
(NO FILES) IF YOU ANSWER YOU WILL BE MARKED BRAINLIEST :)
Answers
Answer:
a= 32
Step-by-step explanation:
Since "a" is a part of a supplementary angle (An angle that adds up to 180º)
What you would need to do is add 58º and 90º (90º because the right angle = 90)
so 58+90 = 148
Then you would subtract 148 from the total of the angle (Which is 180)
so 180 - 148 = 32, And that shows that a = 32

Monique's swimming pool filter needs repair. She calls two companies for prices. The

$50 for a service call and $45/h for labour.

b) Find the solution to this linear system
Answers
the first number is the initial service call charge, and the second number/slope is the rate per hour of the company, where x is the number of hours worked
B) x = 4
Since both equations are solved for y, you can set them equal to each other to get

a data set has a mean 25 and standard deviation 5 find the z score of 39
Answers
Answer:
[tex]\boxed {\boxed {\sf z=2.8}}[/tex]
Step-by-step explanation:
The z-score helps describe a value's relationship to the mean. It tells us how many standard deviations a value is from the mean. The formula is:
[tex]z= \frac{x- \bar x}{s}[/tex]
where x is the value, x-bar is the mean, and s is the standard deviation.
We know the data set has a mean of 25 and a standard deviation of 5. The value we are finding the z score for is 39.
x= 39 x-bar= 25 s=5Substitute the values into the formula.
[tex]z= \frac{ 39-25}{5}[/tex]
Solve the numerator.
[tex]z= \frac{ 14}{5}[/tex]
[tex]z=2.8[/tex]
The z-score for 39 is 2.8. This means a value of 39 is 2.8 standard deviations greater than the mean.

Maya owns a house valued at $432,600. She still owes $233,458 on her mortgage. How much equity does she have in the house? (3 points)
Answers
Answer:
$199,142
Step-by-step explanation:
Given that
The value of the house i.e. assets is $432,600
The mortgage i.e. liability is $233,458
We need to find out the equity
As we know that
The accounting equation is
Total assets = Total liabilities + total equity
$432,600 = $233,458 + total equity
So, the total equity is
= $432,600 - $233,458
= $199,142
Answer:
No, she is not correct. She has only $30,000 in home equity. Equity is the value of ownership in an asset minus any debts owed on it. $315,000 minus $285,000 is $30,000.

Below is the normal distribution curve for height (inches) of NBA basketball players.
What is the standard deviation?
Answers
Answer: standard deviation = 8
This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".
Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.
