23=x-9;x=14 how do I figure out if this is a solution of the equation?

Subsitute 14 back in for x. So you should get
23 = (14) - 9
If this is correct, both sides should equal each other.

However, it is not, because 23 $\neq$ 5.

x=32 is the solution.

There is no solution because x is incorrect.

x should be 32

What is the correct definition for tan 0

Reptile [31]

$tan\theta=\frac{sin\theta}{cos\theta}\\\\\\Look\ at\ the\ picture.\\\\In\ a\ right\ triangle:\\\\sin\theta=\frac{a}{c};\ cos\theta=\frac{b}{c};\ tan\theta=\frac{a}{b}\\\\\frac{sin\theta}{cos\theta}=\frac{\frac{a}{c}}{\frac{b}{c}}=\frac{a}{c}\times\frac{c}{b}=\frac{a}{b}=tan\theta$

Indicate in standard form the equation of the line passing through the given points. X(0, 6), Y(5, 6)

Olegator [25]

(0,6)(5,6)
notice how the y values are they same.....this means u have a horizontal line with a 0 slope.

y = 0x + 6...slope intercept form
0x + y = 6 <==== standard form

Joe drove 538 miles in 9 hours 15 minutes. what was his average speed per hour

Lynna [10]

I am not sure but I think you have to multiply 538 and 9 and get 4842 then divide 4842 by 15 and get 322.8. ( I am not sure if I'm right ).

Trey is solving his equation, and the last line of his work is "-2 = 2". What does this mean?

oksian1 [2.3K]

Answer:

it means that his equation is not true.

Step-by-step explanation:

-2=2 is obviously incorrect, so we must assume that the equation isn't true.
