Answer: Equation Classification
: A. Possible and Determined;
B. Possible and undetermined and C. Impossible:
Step-by-step explanation:
A. Possible and Determined: These are equations that admit at least one solution.
Example: 2x = 3 → x = <u>3
</u>
2
B.
Possible and undetermined:
They are equations that have infinite solutions.
Example: x + 2 = x + 2 → The unknown x assumes infinite numerical values. Thus, the equation has infinite solutions.
C. Impossible: Has no solution.
Examples:
0x = 4 → Unable to divide 4 by 0.
y = y + 2 → y - y = + 2 → 0 = +2 → There is no equation without unknown.
Step-by-step explanation:
x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135
5·x + 20 = 135
5·x = 115
x = 23
So the sequence is
23, 25, 27, 29, 31
The second number is 25.
Do you agree?
If you are trying to find h, then its very simple.
So lets see 5+7=12
So 17-12=5
So lets check to see if h=5
5+5+7
5+5=10+7=17 so h is 5. :)
Answer:
A = 26.6°
Step-by-step explanation:
To obtain the measure of angle A :
We use the trigonometric relation :
Tan A = opposite / Adjacent
Tan A = 6 / 12
Tan A = 1/2
A = tan^-1(1/2)
A = 26.565°
A = 26.6°
