Answer:
C. 516 in2
Step-by-step explanation:
I took the test last week and I got this question corrected
The x-coordinate of the vertex can be found by -b/2a where the equation is ax^2 + bx + c
3x^2 + 6x + 3
b is 6, and a is 3
-b/2a = -6/2(3) = -6/6 = -1
The x-coordinate of the vertex is -1. To find the y-coordinate plug the x-coordinate into the equation and solve for y.
f(-1) = 3(-1)^2 + 6(-1) + 3
= 3(1) - 6 + 3
= 3 - 6 + 3
= 0
The y-coordinate is 0
The vertex is (-1, 0)
Answer:
9y = 18 + 7x
y = 2 + 7/9x
Just rearrange and put into that form
Answer:
y - 50
Step-by-step explanation:
Not sure if that's what you are looking for, but 50 less than a number is the number minus 50
system of equations means that we have a given number of equations with the same solutions.
If you only have tables, this means that you need to have one table for each equation:
For example, if you are working only with two variables, x and y, in those tables you can see the pints (x, y) that belong to each equation.
Now, a point (x, y) will be a solution of the system of equations only if it belongs to the data table for each equation
This would mean that if you graph those data sets, the graphs will intersect at the point (x, y) that belongs to all the tables of data.
another way may be using the data in the tables to construct the equations, but you said that you only want to use the tables, so this method can be discarded.
