The answer is 45°
By determining the angles of triangle ACB (A=30°, B=45°, C=105° (total of 180°)) and knowing that angle 1 correlates to angle 4 ((1)°=(4)°), we can find angle 1, which is 45°, equal to angle 4.
In an algebra problem, you don't set the answer-goal and say "Go for it!"
There is only one correct answer, so the only appropriate way to go about it is to say "Here is the equation. Find the solution.?"
Maybe 27 is the solution, and maybe it's not.
We're about to find out.
You said 2/3 x - 7 = 11
Add 7 to each side: 2/3 x = 18
Divide each side by 2 : 1/3 x = 9
Multiply each side by 3 : x = 27 .
So yes, the correct solution is 27. And that's how to find it.
Answer:
The answer is c) y= 1.8(2.5)^x
Step-by-step explanation:
I just took the test.
My understanding it would be letter ( i ) because it is imaginary.
The answers are revealed by subtracting the right side of the equation from both sides.
(a) (2x+3x-6) -(10+4x) = 0
... x -16 = 0 . . . . one solution; neither
(b) (17+5x) -(23+4x-6+x) = 0
... 0 = 0 . . . . . . . an infinite number of solutions; an identity
(c) (7x+4) -(5x+8+2x-10) = 0
... 6 = 0 . . . . . . . no solutions; a contradiction
