Answer:

Equation: P(w) = 4w + 8

Step-by-step explanation:

The step is zero. That and being told that the relationship is linear.

The general equation is P(w) = mw + y intercept.

When w = 0 then P(w) = 8

The only way that can happen is when P(w) = 0 + y intercept

y intercept = 8 because P(w) = 8

So far what we have is P(W) = mx + 8 So you are starting with 8 rats.

Now suppose w = 2. The number of rats P(2) that you get is 16

So you are solving for m.

16 = m*2 + 8 Subtract 8 from both sides

16 - 8 = 2*m + 8 - 8 Combine

8 = 2m Divide by 2

8/2 = 2m/2

m = 4

4•d=d•4

How would i graph the solution set for 1/3x (greater than or equal to) y+2?

Answers

1/3x ≥ y + 2

You’ll have to transform the equation into its slope-intercept form, y = mx + b, so that you could graph the line. Set y to “=“

1/3x = y + 2
Subtract 2 from both sides

1/3x -2 = y + 2- 2

1/3x - 2 = y or y = 1/3x - 2

Next, to graph the solid line, you need at least two points to plot. We can start with the y-intercept, (0, -2). Another point to use is the x-intercept. To solve for the x-intercept, (a, 0), set y = 0:

0 = 1/3x - 2
Add 2 on both sides:

0 + 2 = 1/3x - 2 + 2
2 = 1/3x

Multiply both sides by 3 to solve for x:
2(3) = (3) 1/3x

6 = x

Therefore, the x-intercept = (6,0).

Plot the intercepts on the graph and connect those two points to create line.

Next, to identify which half-plane region to shade, choose a convenient test point (not on the line) to see whether it part of the solution. We could use the point of origin, (0, 0). Substitute its values into the linear inequality:

1/3x ≥ y + 2

1/3(0) ≥ (0) + 2
0 ≥ 2 (false statement). Therefore, you must shade the half-plane region where it doesn’t contain the test point, (0, 0).

Attached is the graph where it shows that the shaded lower half-plane region.

Ana and Ling are solving |3x + 14| = -6x.
Is either of them correct?...............................
Explain your reasoning.

Answers

Answer:

No! Both are wrong!

Step-by-step Explanation:

the value of absolute function, (|.|) is always positive

that means -6x always has to be positive

and for -6x to be positive x has to be negative

(since, two negatives make a positive)

therefore, the value of x to the equation will be a negative value and not a positive one.

Ana thinks both positive and negative values of x will be the solution, whereas Ling thinks negative value of x can't be a solution. So, they're both wrong.

ONLY negative value of x will be the solution.

A = 2π(r cm) = 2πr cm

For a radius of (2r cm), the circumference is ...

B = 2π(2r cm) = 4πr cm

Then the difference between the circumferences is ...

B -A = (4πr cm) -(2πr cm) = 2πr cm . . . . difference in circumference

Write an equation of the line in slope intercept form for (0,3) and (4,2)

Answers

Answer: 13

Step-by-step explanation:

the slope is the y/x ratio of the y and x coordinate differences when going from one point to the other. and it is always the factor of x in the equation.

x changes by 4 units (from 0 to 4), y changes by -1 unit (from 3 to 2).

so, the slope is -1/4.

the intercept means the intercept with the y-axis. and that means the y value when x = 0. which is given already by the first point : 3

so, the equation is

y = -1/4 x + 3

The scale factor is 2 because they are scaled from each other, meaning they have proportional side lengths. (The angles are also the same <hint for the next question>)

If the top side is 2.5, and the bottom is 5, then you divide to find the scaled factor since they correlate to each other.

If the side lengths on A is multiplied by 2, you can do that to the missing sides to find the answers.

What's the domain of this function graph

Answers

Answer:

D) [0, ~)

Step-by-step explanation:

Domain of a Function:

the domain of a function is the set of values of x, the independent variable, that are responsible for the graph of the function.

For Example:

suppose, we have a function:

f(x) = 3x - 1

and it's domain is {1, 2, 3}

that means, the corresponding value of f(x) to these 3 values of x will be DEFINED, I.e., they exist and can be plotted on a graph.

The given function:

Therefore, for the given function, it's domain will be those values of x(the ones plotted on the horizontal line), that give some value to the function ,i.e., for which we can draw it's graph.

and since the graph starts from x = 0 and continues towards infiinity

(the arrow on the curve shows that the graph continues and hasn't yet come to a stop.)

So, that way we got [0, ~). ^^
