Answer:

D. linear; y = – 3x –6

Step-by-step explanation:

Answer:

Option (2).

Step-by-step explanation:

From the figure attached,

Since there is a common difference in each successive term and previous term of y,

y_{2}-y_{1}=-9-(-6)

= -3

y_{3}-y_{2}=-12-(-9)

= -3

Therefore, this data represents a linear equation.

Now we choose two points from the table given.

Let the points are (0, -6) and (1, -9)

Slope of this line 'm' = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m = \frac{-9+6}{1-0} = -3

Y-intercept 'b' = -6

Equation of the line will be,

y = -3x - 6

Option (2) will be the answer.

Answer: The correct answer is c

Step-by-step explanation: you would have to plot your graph and the put the answer in slop intercept for y=mx+b or y=-3x-6

Answer:

exponential; y = –6 • 1.5x

Step-by-step explanation:

1.5 x 1 = 1.5

1.5x-6= -9

A certain antihistamine is often prescribed for allergies. A typical dose for a 100-pound person is 25 mg every six hours. Comp

koban [17]

Given that a certain antihistamine is often prescribed for allergies.

And typical dose for 100-pound person is 25 mg every 6 hours.

a) Let us calculate dose per 1 hour for 100-pound person= $\frac{25}{6} mg/hr$

Since 1 week means 7X24= 168 hours, dosage per 1 week = dosage per 168 hours

$=168X\frac{25}{6} = 700mg$

The number of 12.8 chew able tablets would be taken in a week= $\frac{700}{12.8}=54.6875$

Hence number of 12.8mg chew able tablets would be taken in a week is 55.

b) Now we can use earlier answer for this problem, since 12.8mg tablet is replaced with 9ml liquid, 55 bottles of 9ml liquid are to be taken in a week.

Hence amount of liquid histamine should a 100-pound person take in a week = 55X9

=495ml

You and three friends are planning a trip. You want to keep the cost below $90 per person. Write and solve an inequality that re

velikii [3]

Answer: x < 360

Step-by-step explanation:

Let x be the total cost for the trip.

And, Here the total number of person = 4

Therefore, the cost for each person = x/4

And, According to the question, The cost must below $90 per person.

Therefore, x/4 < 90

⇒ x < 360

Which is the required inequality for the situation.

The volume of a cylinder is 770 cm. It's height is 5 cm. Find its approximate radius.

Alinara [238K]

Hey there,

The equation for the volume of a cylinder is V = πr²h.

The first step into finding the radius is to plug in what you already know into the equation:

770 = πr²5

We divide both sides by 5:

154 = πr²

Now we divide both sides by π:

49.0197224723 = r²

Finally we just do the square root of 49.0197224723:

7.0014086063 = r

The radius therefore would be about 7cm.

Hope I helped,

Here is a riddle:

lilavasa [31]

Answer:

The system of inequalities that represents this situation will be:

$f + s < 10$

$f - s > 3$

Step-by-step explanation:

Let 'f' represent the first number

Let 's' represent the second number.

Given that the sum of the two numbers is less than 10. As 'less than' can be represented by '<'.

so the inequality would be: f + s < 10

Given that If we subtract the second number from the first, the difference is greater than 3. As 'greater than' can be represented by '>'.

so the inequality would be: f-s > 3

Thus, the system of inequalities that represents this situation will be:

$f + s < 10$

$f - s > 3$
