Answer:
y=1
Step-by-step explanation:
Plug in 2 for x in the original equation, this gives you y=2(2)-3. 2(2)=4 and 4-3=1 therefore y=1.
is this a function? im lost and don't understand math
Answer:
No
Step-by-step explanation:
To be a function, there can only be 1 output for each input.
3/4 has two outputs (3 and 5), so this is not a function.

Answer:
Kindly check explanation
Step-by-step explanation:
For every 3 hours of weeding performed, I consume 5 litres of water.
This means that, I drink 5 litres of water whenever I weed for a total of 3 hours.
The unit rate :
The liters of water consumed per hour :
3 hours = 5 litres
1 hour = x
3x = 5
x = 5 /3
x = 1.67 litres
1.67 litres of water per hour of weeding performed

If sydney answer 15 questions in the first section correctly what is the minimum number of questions she must have answered correctly in the second section
Answer:
8 Is correct on EDGE 2020
Step-by-step explanation:
Just took the test and got it right
The question was incomplete. Below you will find the missing content.
The questions on the first section on a test value 3 points and the questions in the second section carries 5 points. if sydney answer 15 questions in the first section correctly what is the minimum number of questions she must have answered correctly in the second section.And the maximum points she scored is 80.
Answer:
Sydney must have answered at least 8 answers in the second section.
Concept
What is Inequality?
Inequality is a condition which compare algebraic expression using greater than(>), less than(<) symbols. It also shows values greater than equal to(≥), less than equal to(≤) and not equal to(≠) signs to solve the equation.
let x represent the number of correct questions in the first section, and let y represent the number of correct questions in the second question.Therefore the inequality representing her score is 3x + 5y > 80
Solution:
Following the inequality 3x+5y>80, 3x represents sydney's score in the first section which is equal to 3ₓ15 = 45
Now she needs to solve 8 questions in the second section to score
5 ₓ 8 = 40 for the inequality to be maintained.
i.e 3 ₓ 15 + 5 ₓ 8 > 80
45 + 40 > 80
85 > 80
If she solves 7 questions in the second section then the total score will be 45 + 45 ⊅ 80
Therefore sydney answers 8 questions correctly in the second section.

Answer:
Minimum, Vertex(1,-7) and sorry what do you mean by aos? i dont get that please type in the comments I'll answer that too. Hope you understand the rest
Step-by-step explanation:
The vertex of a parabola means the stationary point/turning point which is denoted by the following:
[tex]x=\frac{-b}{2a} \\[/tex]
and for y we just simply put the value of x that we get into the equation so lets get started
The equation [tex]y=x^2-2x-6[/tex] is a quadratic equation
and if we compare it by the standard form [tex]y=ax^2+bx+c[/tex] we get the following values
a=1 , b=-2 , c=-6
and now for the vertex
[tex]x=\frac{-b}{2a}[/tex]
[tex]x=\frac{-(-2)}{2(1)} \\x=\frac{2}{2} \\x=1[/tex]
and now for y
[tex]y=x^2-2x-6\\y=(1)^2-2(1)-6\\y=1-2-6\\y=-7[/tex]
so the vertex is (1,-7)
and the graph is minimum not maximum because the value of a is greater than 0 if the value of a>0 then the graph is minimum and if the value of a<0 meaning a is negative the graph is maximum and here in the equation a=1 which means a>0 then our graph is minimum.

Here is a data set: 5 10 10 10 15 100 after studying the data, the research realized that the value 100 was meant to be recorded as 15. What would happens to the mean and standard deviation of the data set when the 100 is changed to a 15 for the original data set, with the 100, would the median or the mean be a better choice of measure for the center? Explain your reasoning
Answer:
The mean and SD will change
The median is a better measure of the center since it will not change in this case
Step-by-step explanation:
Given that the value 100 was changed to 15, what will happen is that the value of the mean will decrease since there is a lower total value now. This will consequently decrease the value of the standard deviation too.
Yes, the median will be a better choice
This is because, by changing the value of 100 to 15, the value of the median stays the same and thus the previous information would not be changed if the median we used .

Tina recorded the number of calories she burned during a bike ride. The graph shows Tina’s calories burned, y, after x hours. If Tina rode her bike at a constant rate for the first three hours, what was Tina’s average calories burned, in calories per hour, between hour 0 and hour 3?
Answer:
the answer is B because 2x3 is ainzqwndwqncjnjqanc2ejn2qncb
Step-by-step explanation:
400 per hour was Tina's average calorie burn per hour between hours 0 and 3 if she rode her bike at a steady speed for the first three hours.
Given that,
Tina kept track of the calories she expended while riding her bike. After x hours, the graph displays Tina's calories burned, y.
We have to find what was Tina's average calorie burn per hour between hours 0 and 3 if she rode her bike at a steady speed for the first three hours.
What is a graph?
A graph is a visual representation or diagram that displays facts or values in an organized manner in mathematics. The relationships between two or more objects are often shown by the points on a graph.
Therefore, 400 per hour was Tina's average calorie burn per hour between hours 0 and 3 if she rode her bike at a steady speed for the first three hours.
