Question

HELP MATH FINAL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Which is not true about x=27
a) it intersects the axis at 2
b) its slope is undefined
c) it is horizontal
d) it is vertical


Simplify using the distributive property -2(3x-4)


if y varies directly as x and y and y=36 when x=18, find the constant of variation and write the variation equation for this

find the slope of a line through the points (1,-8) and (-3,2)



which is the independent variable in this situation? the cost of a long distance telephone call increases with the number of minutes of the call

Answer 1

hmm.... seems to me that it would be b but let me double check

Answer 2

"Which is not true" so how can there only be 1 right?

Answer 3

true*

Answer 4

x=27 means a vertical line at x=27 for every y

Answer 5

yes it does

Answer 6

so it does not intesept at x=2 its slope is not undefined and it not horizontal

Answer 7

yes but the question asks for 1 wrong answer so.....

Answer 8

unless im missing something here :/

Answer 9

-2(3x-4)

When using the distributive property, we're just going to distribute the -2 to 3x and -4.
So, -2*3x and -2*-4 gives us:

-6x+8

Answer 10

wait what :/ @Butterfly16

Answer 11

x=27 is a vertical line whose slope is undefined. So that means that choice A is untrue and choice c is also untrue. Must be a typo somewhere.

Answer 12

no typo got it right off the test

Answer 13

yes its probably a typo because there is only one wrong answer, i mean untrue

Answer 14

im confused :/

Answer 15

the slope is infinite rise

Answer 16

undefined would be if it not continous

Answer 17

ok so it is defined

Answer 18

right?

Answer 19

Then put c as the wrong answer since it is vertical and not horizontal. But it does not cross the axis at 2 either. Could it possibly be that the equation is x = 2?

Answer 20

i would go with c too, since its the most obvious one

Answer 21

Interesting.

Answer 22

ya interesting ...
