The equation system to represent these two plans is:
c=100+10d, c=40d where c is the total cost and d represents the data used.
We have to understand the plans provided by AT&K and Verikon separately to find the equation system. We know that the total cost incurred is c and the amount of data used is d. It is given that AT&K charges a monthly flat rate of $100 and additional $10 for every gigabyte of data used. We can say that for a month the total cost incurred from AT&K is $100 plus $10xd, the amount of data used.
c=100+10d
For verikon it is given that it does not have any flat monthly rate and it charges $40 for each gigabyte of data used.We can easily say that the total cost in this case is $40 multiplied to amount of data used.
c=40d
Thus the system of equation for the two different plans is
c=100+10d and c=40d

Which is the graph of f(x) = 100(0.7)x? On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 49) and (0, 100). On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 9) and (0, 100). On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 70) and (0, 100). On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 30) and (0, 100). Mark this and return
Answer:
On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 49) and (0, 100).
Which is the graph of the given function?
Here we have the exponential decay:
f(x) = 100*(0.7)^x
So, as x increases, y will tend to zero (because this is a decay, the number with the exponent x is between zero and 1).
Now, if we evaluate in x = 0 we get:
f(0) = 100*(0.7)^0 = 100
Then it goes through the point (0, 100).
If we evaluate in x = 2, we get:
f(2) = 100*(0.7)^2 = 49
Then it also goes through the point (2, 49).
With all that in mind, the correct option is:
"On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 49) and (0, 100)."
The product of two number is -100. One of the factor is less than 10 and more than 0
The given problem has 4 different solutions as below.
(1, -100)(2, -50)(4, -25)(5, -20)Given that the product of the two numbers is -100.
And one of the factors is less than 10 and more than 0.
Assume c and d are the two required numbers.
Then we have cd = -100, here 0 < c <10.
We know that the factors of 100, which are less than 10 and greater than 0 are 1, 2, 4, and 5.
When c = 1, we get 1 x d = -100 ⇒ d = -100
When c = 2, we get 2 x d = -100 ⇒ d = -100/2 = -50
When c = 4, we get 4 x d = -100 ⇒ d = -100/4 = -25
When c = 5, we get 5 x d = -100 ⇒ d = -100/5 = -20
So, the other factors corresponding to the above factors are -100, -50, -25, and -20.
Therefore, the given problem has 4 different solutions as below.

One number is seven less than a second number. Five times the first is 13 more than twice the second. Find the numbers
The two numbers are found as 9 and 16.
What is explained as the linear equation in two variables?A linear equation in 2 variables is one that is written in the form ax + by + c = 0, where a, b, and c are real numbers and also the coefficients of x and y, i.e. a and b, are not equal to zero. For example, 17x + 4y = 9 and -x + 6y = 12 are two-variable linear equations.For the given questions;
Let the first number be 'a'.
Let the second number be 'b'.
Then, first number is seven less than a second number.
a = b - 7
Now, 5 times the first is 13 more than twice the second.
5a = 2b + 13
Put the value of a in above equation;
5(b - 7) = 2b + 13
Simplifying;
5b - 35 = 2b + 13
3b = 48
b = 16 (second number)
a = b - 7
a = 16 - 7
a = 9 (first number)

What in mathematics is a parallelogram?
A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, and a quadrilateral with equal sides is known as a rhombus.The area is always given by squared units and never by single units!
The area of a parallelogram is given by the equation
A = b * h

Step-by-step explanation:
We first rewrite the equation in slope-intercept form y = ax + b, where a is the slope and b is the y-intercept(where x is equal to 0).
24x + 64y = 384
64y = -24x + 384

For 6 hours the temperature is held steady
Solution :
Line Graph:
A line graph—also known as a line plot or a line chart—is a graph that uses lines to connect individual data points. A line graph displays quantitative values over a specified time interval. In finance, line graphs are commonly used to depict the historical price action of an asset or security.
Line graphs can be compared with other visualizations of data including bar charts, pie charts, and (in trading) candlestick charts, among others
Temperature Rose:
It is the increase over ambient temperature of the winding due to energizing and loading
stayed steady:
A steady situation continues or develops gradually without any interruptions and is not likely to change quickly.
Temperature fall :
Temperature drop (T1−T2) is a direct indication of energy extracted. For a given resource, it is dependent on T2 which is in turn dependent on the minimum temperature of the process Ti.
There, we can see that the temperature between 12 noon to 6 pm is not changed much.
therefore we can say that for 6 hours the temperature is holding steady.

Please check the image attached aside with the graph of the quadratic equation.
How to graph a quadratic equation by matching three pointsIn this problem we have a quadratic equation, of which we should plot the graph by matching five points. We can make use of its vertex, two roots, y-intercept and other point. First, determine the vertex of the quadratic function:
- x² - 12 · x - (35 + y) = 0
x² + 12 · x + (35 + y) = 0
12² - 4 · 1 · (35 + y) = 0
144 - 4 · (35 + y) = 0
144 - 140 - 4 · y = 0
4 · y = 4
y = 1
- x² - 12 · x = 36
x² + 12 · x + 36 = 0
(x + 6)² = 0
x = - 6
The vertex of the quadratic equation is (x, y) = (- 6, 1).
Second, calculate the roots of the quadratic equation:
- x² - 12 · x - 35 = 0
x² + 12 · x + 35 = 0
(x + 5) · (x + 7) = 0
The roots of the quadratic equation are (x, y) = (- 5, 0) and (x, y) = (- 7, 0).
Third, determine the y-intercept of the quadratic equation:
y = - 0² - 12 · 0 - 35
y = - 35
The y-intercept of the quadratic equation is (x, y) = (0, - 35).
And fourth, find another point by evaluating the quadratic equation:
y = - 1² - 12 · 1 - 35
y = - 48
The remaining point is (x, y) = (1, - 48).

a bottle weighs 300gand holds 630ml,how much does it weight if i fill it with water
If a bottle weighs 300g and can hold 630ml, then it will weigh approximately 930g when filled with water.
As per the question statement, a bottle weighs 300g and can hold 630ml.
We are required to find out the weight of the bottle when it is filled up with water.
To solve this question, we need to know about the concept of density of a substance, i.e.,
[tex]Density=\frac{Mass}{Volume}\\ or, Mass=[Density*Volume][/tex].
And density of water is 1gm/ml, i.e., 1gm of water has a mass of 1ml.
Using the above info, we will calculate the mass of 630ml of water and then we will have to add up the mass of water and the mas of the bottle to obtain our desired answer.
Using the unitary method, if 1ml of water has a mass of 1gm, then,
630 ml of water has a mass of [tex](630*1)=630\\[/tex] gms.
Hence, total weight of the bottle filled with water will be
[tex](630+300)=930[/tex] gms.
Density: Density is the measure of degree of compactness of a substance, calculated as the ratio of Mass to volume of a substance.Unitary Method: This is a technique for solving a problem where first, we find the value of a single unit, and then find the necessary value by multiplying the single-unit value.To learn more about Unitary Method, click on the link below.

According to the question, first day it rained 6 inches. Then it rained 2/3 every day after that. Solving the fractions, we get that second day it will rain,
(6 × 2/3) = 4 inches as it rained 2/3 every day after that .
So, it rained a total of, 6 + 4 inches = 10 inches in a week.
We have been given that it rained a total of 10 inches in a week. While solving the fraction, we found that it rained for 10 inches in just days, 6 inches in a day and 4 inches the other day. This tells us that it will not rain for the remaining 5 ( 7 - 2 ) days.

Step-by-step explanation:
Use Pythagorean Theorem which says
leg^2+leg^2=hyp^2
90^2+90^2= c^2
8100 +8100=c^2
16200 = c^2
sqrt16200 = c
c ~= 127.27922
Round to one decimal place.
c ~= 127.3 feet
OR, use the shortcut of Special Right Triangles, 45°-45°-90° where, the long side (hypotenuse) is the leg•sqrt2
The legs are 90.
