Have a good day! :D

The required four points are (-5,-1), (1,-1), (-2,-4) and (-2, 2), which are 3 units away from the point P(-2,-1).

A surface with two dimensions known as the coordinate plane is created by two number lines. The x-axis is a single number line that runs horizontally. The y-axis is a vertical number line, which is the other number line.

In the given plane,

Coordinate of point P is (-2,-1)

The four points that are 3 units away from the point P(-2, -1) can be,

(-5,-1), (1,-1), (-2,-4), (-2, 2)

The points (-5,-1), (1,-1), (-2,-4), (-2, 2) are presented on the coordinate plane.

Answer:

p*15%

p*15%*6%

Step-by-step explanation:

Answer:

Part A: 0.85p

Part B: 0.901p

Step-by-step explanation:

The phone's original price: 100%

The phone's sale price: 15% off the original price

p = original price of the phone

Part A:

100% - 15% = 85%

85% = 0.85

The expression: 0.85p

Part B:

6% = 0.06

0.06 * 0.85p ==> (the sales tax * the discounted price of the phone)

0.051p

0.85p + 0.051p

0.901p

y = -4x

When x = 4, y = -16

When y = 20, x = -5

Step-by-step explanation:

First off, definitions: Direct variations refers to two variables being related with neither being the denominator of a fraction. (nothing along the lines of y = 1/x)

So, given that, I simply found what the ratio was between the two values. Something like buying gas at the gas station. The ratio between the gas you get and the money you pay is the price per gallon of gas. In this case, the proportion is -4 (-16 divided by 4).

Thus we have a relationship. For each y, you have negative four x's. Thus, y = -4x.

Finding the value of x when y = 20 simply requires plugging values in. Remember, a fundamental principle in all of Algebra is substitution. If two things are equal, they are interchangeable. So, if you saw "3 + 4" in a mathematical expression, you could simply erase it and write 7, so long as no other mathematical rules (multiplication before addition, for instance) interferes.

Thus, if y = 20, we can take our original equation and replace y with 20.

y = -4x       =>     20 = -4x

Then, simply solve for x, keeping in mind that when two items in math are written against each other, it means multiplication. Thus, we reverse the multiplication to division and divide both sides of the equation by -4.

20 / -4 = -5

Answer:8

Step-by-step explanation:16

An absolute value that can represent the solution set is: |x - 2|=4

From the number line, we have the domain of the x values to be:

x = -4 to 6

This means that the least x value is -4, and the largest is 6

The absolute value equation is given as:

|x - c|=d

Assume that d = 4.

So, we have:

|x - c|=4

Assume that c is 2.

So, we have:

|x - 2|=4

When solved, we have:

x = -2 or x = 6

-2 and 6 are within the domain of the number line.

Hence, an absolute value that can represent the solution set is: |x - 2|=4

Answer:

81/450 or 18%

Step-by-step explanation:

Since you are trying to get the probability model for the chance silver will be selected, you add up 81,117 and 252. This gets you 450denominator and since you are trying to find the probability for sliver, you put 81 in the numerator. This gets the you fraction 81/450. If you divide it, you get 0.18. Now if you are trying to make a decimal into a percent, you move the decimal point two spots to the right. So, 0.18 becomes 18%.

we need to know how to solve x so maybe give a little more help please

Step-by-step explanation:

Answer: Since 5700 years is the "half-life" exactly 0.25 mg will remain.

Step-by-step explanation: Well, we know that half of it will change into another form in 5700 years, so if you start with .5 mg than in 5,700 years you would have half or .25 mg. 11,400 is another half life so half of .25 = .125 mg. 22,800 is two more half lives so half .125 twice.

Answer:

The answer is C

Step-by-step explanation:

Use the Point-Slope Equation by doing y2-y1/x2-x1

Let say that 10 is x2 and 16 is y2. We can also say that -5 is x1 and -2 is y1.

Now Subtract 16 by -2

Do the same with 10 and 2.

We should get y=6/5x+b

We are halfway through now. We have to find the Y intercept.

let's replace x,y with -5,-2 which were one of the points.

-2=6/5(-5)+b

Once we simplify, we get y=4

Therefore, the answer is y=6/5x+4, or C

Hope you understand

Answer:

c?

Step-by-step explanation:

Answer:

a: y=70x

b: y=70x+100

c: They are parallel to each other, with equation b's line being 100 dollars above equation a.

Step-by-step explanation:

They both have the same slope (70), but new customers will have a y intercept of 100 because of the one-time fee.

Don't forget to like and rate!

The equation is given by y = 70x and for the new customers it is given by y = 70x + 100.

A linear equation is of the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept

Let x represent the number of months of service, and y represent the total amount  

a) A cable company charges $70 per month, hence:

y = 70x

b) The is an additional one-time $100 service fee, hence:

y = 70x + 100

Hence the equation is given by y = 70x and for the new customers it is given by y = 70x + 100

Answer: A: y-x = -4

Step-by-step explanation:

To have an infinite number of solutions, two linear equations must be on top of each other, (so they intersect at every point). What this question is really asking is the equation for the plotted line!

This is simple enough:

two points are given, so lets fine the slope:

Slope = (y2-y1)/(x2-x1) = (-4 -0)/(0-4) = -4/-4 = 1

the slope is 1:

putting this into slope intercept form, we have y = x + b.

since b is the y intercept, and that is already given as -4, our completed equation is:

y = x - 4

which can be rewritten as y - x = -4

So your answer is the first option.

Answer:
