Answer:

y = mx + 5; m < 0

Step-by-step explanation:

The question mentions that the slope of the line is negative and the y-intercept is 5. The general form of the straight line is given by y = mx + c. Since "c" in the equation is the y-intercept, therefore, c = 5. This means that all the straight lines passing from the point (0,5) can be expressed in a general form y = mx + 5. However, the question mentions that the slope is negative and demands the general equation of all the negatively-sloped straight lines passing from (0,5). Therefore, for the condition to be met, m has to be negative. So the correct answer is y = mx + 5, where m is negative.

Answer:

$370

Step-by-step explanation:

You already have 90 dollars so we can put that to the side for right now

If you're charged $35 at an hourly rate for 8 hours then you have to multiply the two together

30 x 8 = 240

5 x 8=40

240 + 40=280

Now is when your $90 dollars comes in. Now just add the two together and you'll end up with your final answer

280+90=370

Answer:

f(x) +g(x)  = -1.3 - 1.75x

Step-by-step explanation:

f(x) +g(x) is simply obtained by adding the two given functions, f(x) and g(x). We are given that;

F(x)= 3.7-2x and g(x)= 0.25x-5

f(x) +g(x)  = 3.7-2x + (0.25x-5)

f(x) +g(x)  = 3.7 -5 + 0.25x - 2x

f(x) +g(x)  = -1.3 - 1.75x

Answer:

depreciation is $3,333.33 per year

Step-by-step explanation:

Initially : date = 2006, worth = $34,500

Finally : date = 2009, worth = $24,500

if we let x = date and y = worth, we end up with two points (coordinates) on the x-y graph

i.e

Initial = Point 1 (2006, 34500)

Final = Point 2 (2009, 24500)

The rate of change is simply the slope, m of the line joining these two points

given by:

m = (34500 - 24500) / (2006-2009)

= 10000 / -3

= -3,333.33

hence the annual rate of depreciation is $3,333.33 per year

Final answer:

The boat's value depreciated by $10,000 over 3 years, resulting in an annual depreciation rate of $3,333.33.

Explanation:

The student's question involves calculating the annual rate of change of the value of a boat from the year it was bought (2006) to the year 2009. To find the rate of change, we need to determine how much the value of the boat depreciated over the given time period and then divide it by the number of years.

The boat depreciated from $34,500 in 2006 to $24,500 in 2009, which is a decrease of $34,500 - $24,500 = $10,000 over the course of 3 years. To find the annual depreciation rate, we divide the total depreciation amount by the number of years: $10,000 ÷ 3 years = $3,333.33 per year. Therefore, the annual rate of depreciation is $3,333.33 per year, rounded to the nearest hundredth if necessary.

Answer:

y = -⅘x - 4

Step-by-step explanation:

. So your point is an x-intercept. It happens at times. Alright. Now, we have to know that parallel lines have SIMILAR RATE OF CHANGES [SLOPES], so we keep the -⅘. Moving forward, we simply plug the coordinate into the Slope-Intercept Formula, y = mx + b --> 0 = -⅘[-5] + b. From this, we can see that our y-intercept is [0, -4], so our parallel line is y = -⅘x - 4. Do you understand?

Your question asks which pair represents the y-intercept in the equation.

To find the answer in your question, we are going to need to find the key terms in the question.

Key terms:

y-intercept

y = -5x + 6

With the information above, we can find the answer.

We know that the equation is similar to the equation: y= mx + b

We need to find what the y-intercept is in the equation.

When you look at the equation, y = -5x + 6, you would know that the y intercept would be the last number (6). Therefore, 6 would be our y intercept.

But, we need to get the number 6 in the right ordered pair.

An ordered pair is represented as (x,y).

So, we would plug in the 6 in the y spot, since it's the y-intercept. We would plug in 0 to x, since we're only focusing on the y-axis, any number on this would not allow the ordered pair to be on the y-axis.

This means that your ordered pair should be (0,6).

C). (0,6) should be your FINAL answer

The y-intercept of the equation y = -5x + 6, is represented by the ordered pair (0,6). This is established by substituting x=0 in the equation, which results in y = 6. Hence, the line intersects the y-axis at this point on a graph.

In the equation y = -5x + 6, the y-intercept is the value of y when x equals zero. This can be determined by substituting x=0 into the equation. So, let's do this:

Substitute x = 0 into the equation, we get: y = -5*(0) + 6, which simplifies to y = 6. Therefore, the y-intercept is 6, and in an ordered pair it is represented as (0,6).

So, the correct answer is option C: (0,6). This is the point where the line crosses the y-axis on a graph.

Step-by-step answer:

The answer is circled in red on the output of the calculator, attached.  This is how we need to look for when we use a graphing calculator, which says

"linear regression, y=5.10x+9.12"

However, we need to check the answer by looking at least one point on the curve.  Say we use the point (10,60) on the straight line, and compare with y(10) = 5.10*10+9.12 = 60.12, quite close to 60.  The other answer options all give numbers far away from 60 when x=10.

Answer:

The correct option is 2.

Step-by-step explanation:

The given data is

x               y

5              36

9              64

12            72

18            96

26           141

35           189

The general form of regression line is

[tex]y\approx ax+b[/tex]

From the given picture of graphing calculator, it is clear that the equation of regression line is

[tex]y\approx 5.098x+9.118[/tex]

Approx the value of a and b upto tenth.

[tex]y\approx 5.10x+9.12[/tex]

The equation of the line of best fit is y ≈ 5.10x+9.12. Therefore the correct option is 2.

The inverse function is: [tex]\[ y = \ln(x + 4) - 3 \][/tex]

To find the inverse of the function [tex]\( y = e^{x+3} - 4 \)[/tex], we'll first swap the roles of x and y and then solve for y.

1. Start with the original function:

[tex]\[ y = e^{x+3} - 4 \][/tex]

2. Swap x and y:

 [tex]\[ x = e^{y+3} - 4 \][/tex]

3. Solve for y:

[tex]\[ x + 4 = e^{y+3} \] \[ e^{y+3} = x + 4 \][/tex]

4. Take the natural logarithm (ln) of both sides to isolate y:

[tex]\[ \ln(e^{y+3}) = \ln(x + 4) \][/tex]

[tex]\[ y + 3 = \ln(x + 4) \][/tex]

5. Subtract 3 from both sides:

[tex]\[ y = \ln(x + 4) - 3 \][/tex]

Answer:

Range = (-∞,0) U (0,∞)

Step-by-step explanation:

The given function is:

f(x) = (x-1)²/x³-2x²+x

We can reduce the denominator:

= (x-1)²/x(x²-2x+1)

we know that a²-2ab+b² = (a-b)²

= (x-1)²/x(x-1)²

= 1/x

The function 1/x is undefined for x = 0.

Hence, its domain lies in (-∞,0) U (0,∞).

Hence x can either be less than or greater than zero.

The function f(x) is greater than zero when x<0.

The function f(x) is less than zero when x>0.

There is no way the function can be zero because the numerator is constant.

Hence the domain of the function lies in the interval:

The probability of a student chosen randomly from the class playing basketball or baseball is 0.84.

The probability that a student chosen randomly from the class plays basketball or baseball can be found using the principle of inclusion-exclusion. First, we add the number of students who play basketball (17) and baseball (10) together, which gives us a total of 27 students. However, we have double-counted the 6 students who play both sports, so we subtract that number from the total. Therefore, the number of students who play basketball or baseball is 27 - 6 = 21. The probability is then calculated by dividing the number of students who play basketball or baseball by the total number of students in the class: 21/25 = 0.84.
