"Explain why the solution of a system of linear equations is the point of intersection of their graphs"
Can you please explain this to be in a simpler form?
Answer:
Step-by-step explanation:
The solution of a system of linear equations is the point of intersection of their graphs because the intersection represents the only x or y values that will satisfy both/all equations. The graph visually shows that the intersection of these equations is the only spot on the graph that all of the equations have in common. This means that only this spot will satisfy all equations. For example, the intersection may be (0,1); this means that for all equations an x value of 0 will always result in the y value of 1. However, an x or y value that satisfies one equation may not satisfy the others if they do not lead to the desired outcome.

Answer: D (Mean is 85)
Explanation:
"The list below shows the quiz scores for a group of students.
95, 80, 80, 85, 80, 85, 90"
The choices talk about median and mode so we find those first:
Median: find by taking which is the middle number when the data is from low to highest
1) rearrange them from low to high
80, 80, 80, 85, 85, 90, 95
2) find middle number
80, 80, 80, 85, 85, 90, 95
The median is 85
Mean: mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers
1) add 80, 80, 80, 85, 85, 90, 95 and get 595
2) There are 7 total numbers so do 595/7 = 85
The mean is 85
D is the correct answer
why?
A is wrong because they are 85 not 80
B is wrong because it is 85 not 80
C is wrong because it is 85 not 80
D is right because it is 85!

Answer:
its the 3rd answer in the row :)
Step-by-step explanation:
Step-by-step explanation:
First, you need to know some terms related to probability. When working with probability, a random action or series of actions is called a trial. An outcome is the result of a trial, and an event is a particular collection of outcomes. Events are usually described using a common characteristic of the outcomes.
Let's apply this language to see how the terms work in practice. Some games require rolling a die with six sides, numbered from 1 to 6. (Dice is the plural of the die.) The chart below illustrates the use of trial, outcome, and event for such a game:
Trial
Outcomes
Examples of Events
Rolling a die
There are 6 possible outcomes:
{1, 2, 3, 4, 5, 6}
Rolling an even number: {2, 4, 6}
Rolling a 3: {3}
Rolling a 1 or a 3: {1, 3}
Rolling a 1 and a 3: { } (Only one number can be rolled, so this outcome is impossible. The event has no outcomes in it.)
Notice that a collection of outcomes is put in braces and separated by commas.
A simple event is an event with only one outcome. Rolling a 1 would be a simple event because there is only one outcome that works—1! Rolling more than a 5 would also be a simple event because the event includes only 6 as a valid outcome. A compound event is an event with more than one outcome. For example, in rolling one six-sided die, rolling an even number could occur with one of three outcomes: 2, 4, and 6.
When you roll a six-sided die many times, you should not expect any outcome to happen more often than another (assuming that it is a fair die). The outcomes in a situation like this are said to be equally likely. It’s very important to recognize when outcomes are equally likely when calculating probability. Since each outcome in the die-rolling trial is equally likely, you would expect to get each outcome of the rolls. That is, you'd expect the rolls to be 1, of the rolls to be 2, of the rolls to be 3, and so on.
A spinner is divided into four equal parts, each colored with a different color as shown below. When this spinner is spun, the arrow points to one of the colors. Are the outcomes equally likely?
A) Yes, they are equally likely.
B) No, they are not equally likely.
Answer:
All the outcomes are equally likely. Each color provides a different outcome, and each color takes up the circle. You would expect the arrow to point to each color of the time.

I don't usually use this website anymore, but here's an answer I found for you.
Answer:
-14.57
Step-by-step explanation:
Subtract -2.67 by 5.95×2 since there were two days it equals -14.57
(Or)
-2.67 + x2 (x =-5.95)
-2.67 + (2*-5.95*) = -14.57
Part 1:
The account will be -14.57 after two days.
Step by step:
What I do is just forget the negatives until the end.
5.95 + 5.95 (two days) + 2.67 = 14.57
Bring back the negative: -14.57
Part 2:

Answer:

2. $735.03
3. $10707.55
4. $17631.94
5. $19635.72
Step-by-step explanation:
1st Question:
The interest rate is 7% for each year. This means that each year the person has to pay 7% more than the previous amount. So we need to multiply the initial amount by (0.07+1=1.07) in order to get the interest for the first year. if we want to find the second year's interests then we will have to multiply 2 (1.07)'s and so on.
in this case our function is: 600*(1.07)^t=P(t)
when t=2 P(2)=600*(1.07)^2=$686.94
2nd Question:
Function: 600*(1.07)^t=P(t)
when t=3 P(3)=600*(1.07)^3=$735.03
3rd Question:
initial value=$8500
1+0.08=1.08
Function: 8500*(1.08)^t=P(t)
t=3
P(3)=8500*(1.08)^3=$10707.55
4th Question:
initial value=$12000
1+1.08=1.08
t=5
Function: P(t)=12000*(1.08)^t
P(5)=12000*(1.08)^5=$17631.94
5th Question:
Function: 14000*(1.07)^t=P(t)
P(5)=14000*(1.07)^5
P(5)=$19635.72

Step-by-step explanation:
Basically, try finding the x and y intercept for each problem and then make those your coordinates!!
Step-by-step explanation:
1) So to answer these questions first plot the "b" value (which in number 1's case would be 3).
2) Go up three spaces on the graph. and that should leave you at the point (0,3) Plot this point.
3) Now go down 3 (-3x) and go over one point to the right(this should put you at point (1,1). Plot this point.
4) Move on to the next equation in number one. Go up three spaces on the graph.
5) Go down one and over one until you find that you have plotted a point in which both equations intercept (this point would be (0,3).
6)Repeat this process for the rest of the problems
Tyrone is working with two other students to build a border around the school’s triangular garden. Each student brought in one side of the border, but they all used different units to measure the side lengths. The first side is 312 inches long, the second side is 20 feet long, and the third side is 12 yards long. If the measurements need to be in feet, will the three border pieces make a right triangle?
Convert the third side into feet using a proportion.
Answer:
i would say no but im not fully experienced
Step-by-step explanation:
the reason is that the converted measurements dont even come up to make a full 90 degree, and tis is a right triangle

solve for y: 36=byx
Answer:
y= 36/bx
Step-by-step explanation:
you have to isolate y so you do the inverse operation of b and x to move it to the other side. since it is currently multiplying by Y you divide it on both sides to move it leaving you with 36 being divided by BX .
Can Someone answer this please
Answer:
So the scaling means that per every foot in real life, you have 2.4 centimeters, which means that the scale model would be 48 cm tall.
A. To find your answer, you would divide 48 by 1.2, which is 40. So your model would be 40 bottle caps tall
B. Same as A, all you have to do is divide 48 by 15.2, which would be about 3 popsicle sticks tall (rounded)

Movie Ticket Dilemma
During the grand opening of the new pizza parlor, Steve was hired to give out free
movie tickets to customers. On Friday, he started with a box of tickets, and he
distributed 0.50 of the box; on Saturday, he distributed 1/3 of what was left; on
Sunday, he distributed 0.25 of the remaining amount; on Monday, he distributed 6/18
of what was left; and on Tuesday, he distributed 2/12 of what remained.
At the end of the 5 days, he had 60 tickets left. Determine how many tickets Steve
had when he began to give them away.
