An algebra teacher is ordering new text books for the class. The shipping cost y (in dollars) depends on the number x of books that are ordered, shown in the table. Write a linear model in slope-intercept form for this data. 7 9 13 Number of books (X) Shipping cost (in dollars) (y) 11 43 31 37 49

n

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
