1. if f(x) varies directly with x, and f(x) = 12 when x = 8, write the direct linear variation equation.

a. f(x)=8x
b. f(x)=12x
c. f(x)=2/3x
d. f(x)=3/2x

2.which does not show a direct variation between x and y?

a. y=5x
b. y=6/x
c. y=0.7x
d. y=x/9

3.find the constant of variation for the relationship shown in the following table:

x 1 2 3 4
y 3 6 9 12

Two students were asked if they liked to read. is this a good example of a statistical question? why or why not? a yes, this is a good statistical question because a variety of answers are given. b yes, this is a good statistical question because there are not a variety of answers that could be given. c no, this is not a good statistical question because there are not a variety of answers that could be given. no, this is not a good statistical question because there are a variety of answers that could be given

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.

How many solutions does the nonlinear system of equations graphed below have?
