What is the value of the expression when a=4, b=3, and c=10?

3a

4b-c

a.12

b.4

c.1

d.6

(i think d)

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.
