Please help quick Solve for x.​
Kamila [148]

Answer:

x = 3.75

Step-by-step explanation:

So, lets start with what we know.

Line = 180 degrees

Triangle = 180 degrees, a + b + c = 180

So, we can form the equations,

17x - 1 + <CDB = 180

-17x + 1                -17x + 1

             <CDB = 181 - 17x

and

84 +7x + 5 + <CDB = 180

89 + 7x      + <CDB = 180

-89                              -89 + 7x

                     <CDB = 91 + 7x

Here, we are given 2 values of <CDB, but they must be the same, so let's substitute them into each other

181 - 17x = 91 + 7x

-91 +17x   -91  +17x

90         =        24x

90 / 24  =        24x / 24

3.75       =           x

x            =           3.75

There, you have it, x is 3.75

If you have any questions, please let me know in the comments section of this answer! If you could mark this answer as the brainliest, I would greatly appreciate it!

What is the answer to this and why?
Anna007 [38]

Answer:

Step-by-step explanation

I get the same answer you do, but I'm not at all certain I'm correct. I would have done it just as you did letting each y value define the new x value and then putting the - on the left in at the very end.

f(1) = 3

f(3) = -1

f(-1) = 7

But there is a minus in front of the left most f. That would make it - 7
