Answer:
greater than 7
Step-by-step explanation:
Answer: A is correct option .It is possible for two points to have the same x-coordinate and the same y-coordinate.
Step-by-step explanation:
A scatter plot is a mathematical diagram or 2-dimensional data visualization using Cartesian coordinates to display values for two variables for a set of data by using dots to represent the values occurred for two different variables - one plotted along the x-axis and the other plotted along the y-axis. They show how variables are correlated thats why they are also called correlation plot. For example we have scatter plot with variables as study time and exam grade, so it can happen that 2 students study for same time and got same grade.
Therefore, It is possible for two points to have the same x-coordinate and the same y-coordinate.
Multiply the first equation by -1 to get -4x - y = --5
Then add the second equation 3x + y = 3
+ ____________
-x = -2 or x = 2
then plug in 2 for x in one of the equations and solve for y 4(2) + y = 5
8 + y = 5
Subtract 8 from both sides y = -3
So x = 2, y = -3 or (2,-3)
Answer: X = kuv/ (u+v)
that means that x(u+v)/(uv) = k, a constant. so you want x such that,
x(3+3)/(3*3) = 3(3+1)/(3*1)
x=6
The total cost, if one drink costs $3 is $27.75
- Let the cost of a pizza be x
- Let the cost of a drink be y
If kiyo bought a pizza for 12.75 and four medium drinks to Pauli’s pizza, this expressed as x + 4y
Since a pizza costs $12.75, hence x = $12.75
The function becomes 12.75 + 5y
f(y) = 12.75 + 5y
To get the total cost if one drink costs $3, hence;
f(3) = 12.75 + 5(3)
f(3) = 12.75 + 15
f(3) = 27.75
Hene the total cost, if one drink costs $3 is $27.75
