The equation that best represents the line on the first graph is
5x + 3y = 3
Option C is the correct answer.
The equation that best represents the line on the second graph is
x - y = -7
Option A is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Pick two coordinates that the line passes through in each graph.
First graph:
(0, 1) and (-3, 6)
m = (6 - 1)/ (-3 - 0) = 5/-3 = -5/3
(0, 1) = (x, y)
1 = (-5/3)0 + c
c = 1
Now,
y = (-5/3)x + 1
3y = -5x + 3
5x + 3y = 3
Second graph:
(0, 7) and (-5, 2)
m = (2 - 7) / (-5 - 0) = -5/-5 = 1
(0, 7) = (x, y)
7 = 1 x 0 + c
c = 7
y = x + 7
x - y = -7
Thus,
The equation of the first graph is 5x + 3y = 3.
The equation of the second graph is x - y = -7.

The number of full test tubes Russel fill with water must be discrete number and not rational. 36 test tubes is the answer.
How to Know Cylinder Volume ?Volume of a cylinder can be known either by the use of formula (V = πr²h) or by measuring with the volume of a known liquid.
Given that Russel is doing an experiment for a science fair project. He fills a beaker with water three times. He puts 16.5 milliliters of water in each test tube. How many full test tubes can Russel fill with water?
1. Describe one way to estimate the solution to this problem.
By dividing the amount of milliliters of water in the baker by 16.5 ml
2. Russel calculates correctly and says the answer to the problem is 36.36 test tubes. Is Russel's answer reasonable?
No! The reason is based on the fact that the answer must be a whole number and not a decimal number since the question centered on number of full test tubes filled with water.
Therefore, the correct answer should be 36 test tubes.

How do you find the area of an acute triangle without height?
Answers
The area of the triangle is equal to the squareroot of 10(10-5)(10-7)(10-8), which is equal to 24.
The area of an acute triangle without height can be calculated using Heron's Formula. Heron's Formula states that the area of a triangle is equal to the squareroot of s(s-a)(s-b)(s-c) where s is the semi-perimeter of the triangle and a, b, and c are the lengths of the three sides.
To find the area, first calculate the semi-perimeter of the triangle. The semi-perimeter is equal to one-half the sum of the three sides. For example, if the lengths of the three sides of a triangle are 5, 7, and 8, the semi-perimeter is equal to 5 + 7 + 8 divided by 2, which is equal to 10.
Next, plug the values into Heron's Formula. Using the same triangle as an example, the area of the triangle is equal to the squareroot of 10(10-5)(10-7)(10-8), which is equal to 24.
Finally, calculate the area of the triangle by taking the square root of 24, which is equal to 4.9. Therefore, the area of the triangle is 4.9 square units.

What quadrant does (-a,b) belong
Answers
Coordinate (-a , b ) belongs to second quadrant.
What is a Quadrant?The axes (x-axis and y-axis) of a two-dimensional Cartesian plane system divide the plane into four infinite regions called quadrants. The horizontal line or x-axis and vertical line or y-axis intersect each other at the right angle. The intersection of two lines is known to be the reference point. All the measurement is done by taking this point as the reference (or starting point) in the coordinate system.
"A quadrant is simply defined as the region of a cartesian plane formed when the x-axis and y-axis intersect each other."
Given, Coordinate ≡ (-a , b)
1st Quadrant: The upper right-hand corner of the graph is the first quadrant. In this quadrant the values of x and y both are positive.
2nd Quadrant: The upper left-hand corner of the graph is the second quadrant. In this quadrant, the value of x is negative whereas the value of y is positive.
3rd Quadrant: The lower left-hand corner of the graph is the third quadrant. It contains the negative values of both x and y.
4th Quadrant: Finally, the fourth quarter is at the lower right-hand corner, which has a positive value of x and a negative value of y.
Hence, by the above observation, given coordinate (-a, b) belongs to the 2nd quadrant.

A number between 0 and 1 represents the likelihood of an event, with 0 generally denoting impossibility and 1 denoting certainty. How likely something is to occur is known as its probability. We can discuss the probabilities of various outcomes—how likely they are—when we aren't sure how a particular event will turn out. Statistics describes the examination of events subject to probability. The probability of anything occurring is known as probability. To determine probability, divide the total number of possible outcomes by the number of possible ways an event could occur.2030⋅1929⋅18282030⋅1929⋅1828 = 0.281

Step-by-step explanation:

Phoebe claims that she wants a career with no college or trade school requirements because she could save the money for retirement rather than spending it on education. She estimates her average yearly salary at $35,000 per year with no post-secondary education requirements.
Connor claims post-secondary education will help him get a career with a higher salary and more benefits that he can use in retirement, so the education costs will more than pay for themselves.

Para festeja su cumpleaños,Nancy compró 15 paquetes de pizzetas. Si cocinó 288 pizzetas, cuántos paquetes completos le quedaron?
Answers
Answer:
Nancy consumió 12 paquetes de pizzetas y le quedaron 3 paquetes completos.
Step-by-step explanation:
En primer lugar, debemos descomponer el número total de pizzas como una multiplicación de números primos. Al realizar la descomposición factorial tenemos que:
[tex]288 = 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3[/tex]
Entonces, los familia de divisores de 288 es el siguiente conjunto:
[tex]D_{288} = \{2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144 \}[/tex]
Si tanto la cantidad de paquetes de pizzetas y la cantidad cocinada de pizzetas son números enteros y positivos, siendo la última mucho mayor. Entonces, la cantidad de pizzetas debe ser un número entero y la cantidad de paquetes gastados menor a la cantidad de paquetes comprados y el número entero más cercano a esa cantidad. Entonces, concluimos que Nancy se gastó 12 paquetes de pizzetas, quedándole 3 paquetes completos.
A family buys 5 airline tickets online. The family buys travel insurance that costs $16 per ticket. The total cost is $840. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket.
Answers
Travel insurance for 5 tickets = $16 * 5 = $80
If the price of 1 ticket = x
The price of 5 tickets = 5 * x = 5x
The total cost of tickets and insurance = $840
5x + 80 = 840
Subtract 80 from both sides
5x + 80 - 80 = 840 - 80
5x = 760
Divide both sides by 5
5x/5 = 760/5
x = 152
The price of 1 ticket is $152
Let’s check if x = 152 is a solution for 5x + 80 = 840
5(152) + 80 = 840
760 + 80 = 840
840 = 840
