If you expand this equation first
You get -4u+6+3u=3u+24

And if you simplify that you get:
-u+6=3u+24
Now you need to solve this equation to find u

First bring 3u to the other side to -u-3u (the positive changes to negative)
Now the equation is
-4u+6= 24
Take 6 of both sides
-4u=24-6= 18
-4u= 18
So u= -18/4
Which simplifies to -9/2

Answer: -9/2

In the figure, ∆BAT ≅ ∆CAT. Which statement is not true by CPCTC? ∠CAB ≅ ∠SAB ∠CAS ≅ ∠BAS
Studentka2010 [4]

Answer:

∠CAB ≅ ∠SAB is not true

Step-by-step explanation:

CPCTC means id ABC = XYZ, than A=X, AB=XY, C=Z and so on. Basically the number numbers that come in the same order as the other one is equal.

So ∠CAS ≅ ∠BAS is true but ∠CAB ≅ ∠SAB is not.

Hope this helps. If you have any follow-up questions, feel free to ask.

Have a great day! :)

Dont answer if you dont have the answer I will report you The graph of a function contains the points (–1, –4), (0, 1), (1, 4).
Fantom [35]

Answer:

  • The function is linear because the points are not in a straight line.

Points that lie along the same line are said to be "collinear" and collinear points must have the same slope between any pair of points.
