Answer:
Option B is correct
Step-by-step explanation:
2x² - 6x + 3 = 0
Using Quadratic formula:
x = 
a = 2, b = -6, c = 3
x = 
x = 
x = 2.37
x = 0.63
Answer:
100.00
Step-by-step explanation:
x=number of months until the costs are the same
50 + 20x = 25 + 30x
25 = 10x
x = 2.5 months
50 + 2.5(20) =$100.00
Answer:
1. A table is a data structure that organizes information into rows and columns
2. A column is a vertical group of values within a table. It contains values from a single field in multiple rows
3. A row is a horizontal group of values within a table. It contains values for multiple fields, which are defined by columns
4. A cell is a specific location within a spreadsheet and is defined by the intersection of a row and column
A I don’t really have an explanation but I remember this
Solve the first for y
y=13x-90 and the second is y=x^2-x-42
When there is/are solutions y=y so we can say:
x^2-x-42=13x-90 subtract 13x from both sides
x^2-14x-42=-90 add 90 to both sides
x^2-14x+48=0 expand so that it is easy to factor...
x^2-6x-8x+48=0 now factor 1st and 2nd pair of terms
x(x-6)-8(x-6)=0
(x-8)(x-6)=0
So there are two solutions, when x=6 and 8.
Using either original equation we can find the corresponding values for y. I'll use y=13x-90 because it is easier...
y(6)=-12, y(8)=14 so the two solutions are the points:
(6,-12) and (8,14)
