Answer:
Direct variation is modeled by
... y = k·x
Then the value of k can be found by finding the ratio of any corresponding pair of numbers from your table. I find it convenient to choose the one where x=10, so the math is easy to do mentally.
... y/x = k
... 16/10 = k = 1.6
Then the equation is
... y = 1.6x
_____
Checking the other values in the table, we find that this equation fits all of them, so you do have direct variation.Step-by-step explanation:
Find the equation of the line shown.
Answer:
[tex]\displaystyle y=\frac{1}{2}x-3[/tex]
Step-by-step explanation:
Equation of a line
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The graph of the picture shows two clear points (-4,-5) and (0,-3). We'll use them to find the required equation:
[tex]\displaystyle y-(-5)=\frac{-3-(-5)}{0-(-4)}(x-(-4))[/tex]
Operating:
[tex]\displaystyle y+5=\frac{-3+5}{0+4}(x+4)[/tex]
[tex]\displaystyle y+5=\frac{2}{4}(x+4)[/tex]
Simplifying the fraction:
[tex]\displaystyle y+5=\frac{1}{2}(x+4)[/tex]
Multiplying:
[tex]\displaystyle y+5=\frac{1}{2}x+2[/tex]
Solving for y:
[tex]\boxed{\displaystyle y=\frac{1}{2}x-3}[/tex]

Step-by-step explanation:
Help me with this math problem, I need someone to guide me through it I don’t understand what I’m supposed to do first
Answer:
see below
Step-by-step explanation:
The parent function is x^2 which is a parabola at vertex (0,0)
g(x) = ( x+3) ^2
y = f(x + C) C > 0 moves it left
So the parabola is shifted to the left 3 units
h(x) = -( x+3) ^2
y = −f(x)
Reflects it about x-axis
Means flip it about the x axis

Answer:
d. linear; $25/hour
Step-by-step explanation:
From looking at the graph, we have that renting for 2 hours costs $50, for 4 hours costs $100, for 6 hours costs $150, and for 8 hours costs $200. To find out whether the quantities described in the table are linear, we have to see if there is a constant rate of change of price.
For hour 2 to hour 4, we can see that the price increases by $50. This is the same for hour 4 to hour 6 and hour 6 to hour 8. For every 2 hour time interval, the price increases by $50. Therefore, there is a constant rate of change and the quantities described in the table are linear.
Now we have to find the constant rate of change per hour. We know that the price increases by $50 every 2 hours, so, by dividing both the hours and price increase by 2, the price increases by $25 per hour. So the constant rate of change is $25/hour.
Linear. $25/hour

Sieranise is trying to find the unit price on a 12-pack of granola bars on sale for $2.99. Her sister says that at that price, each bar would cost just under 25 cents. Is she correct, and how do you know? If she is not, how would Sieranise’s sister find the correct price?
Answer:
It is correct, the cost per granola bar is $0.25
Step-by-step explanation:
You would divide 12 and $2.99
2.99/12
Equals to 0.29166666(repeating)
You would then round the number since 0.2491666 is a correct money amount, making it 0.25.
$2.99/12 = $0.25 (rounded)
The cost per granola bar would be just under $0.25.
Hope this helps!

What is the absolute value of negative four
Answer:
4
Step-by-step explanation:
The absolute value is just the positive version of a number so if you have like -28 the absolute value is just 28
Answer:
4
Step-by-step explanation:
Absolute value is the distance of a number from zero, and absolute value is always positive because it's distance.
-4 would be 4 places away from 0 on a number line, so the absolute value of -4 is 4.
When can it be determined that the mean is less than the median?
A. When the histogram is symmetric
B. When the histogram can be closely ap. Foximated by a normal curve.
C. When the histogram is negatively skewed.
D. When the histogram is positively skewed.
Answer:
c. when the histogram is negatively skewed
Step-by-step explanation:
median are resistant to outliers however the mean is not a negatively skewed histogram will affect the mean but not the median so the mean is less than the median for a histogram that is negatively skewed

he
The degree is even and the leading coefficient is negative.
0 The degree is odd and the leading coefficient is positive.
O The degree is odd and the leading coefficient is negative.
Answer: the degree is even and the leading coefficient is positive
Step-by-step explanation:
If the function is increasing to the left and falls to the right,
Leading coefficient of the function will be negative and the degree of the function will be Odd.
Similarly, if the function is increasing to the right and falls to the left,
Leading coefficient of the function will be positive and the degree of the function will be Odd.

A questionnaire was administered to a random sample of 800 acccounting alumni of a large university; however, due to nonresponse and incomplete answers, only 216 questionnaires could be analyzed. Several variables were measured, including age, gender, level of education, income, job satisfaction score, and Machiavellian ("Mach") rating score.
