The equation has exactly 1 real solution.
You can find this by solving it.
8 - 4x = 0 ----> add 4x to both sides
8 = 4x ----> divide both sides by 4
2 = x
You can see there is only 1 and therefore it has one solution.
The correct answer is 81 hours
F(-2)+g(5) = 3(-2) -1 + (-5) + 6
f(-2)+g(5) = -6 -1 - 5 + 6
f(-2)+g(5) = -6
Answer:
Step-by-step explanation:
The figure shows that in triangle NRM.
In order to make NRM a right triangle, following steps are done:
1. (Given)
2. (By the pythagorean theorem in triangle EFD)
3. From the steps one and two, the RHS is equal, therefore by substitution property.
4. Now, f=r by the square root property.
5. Now, As and and f=r, therefore, by SSS postulate , ΔNRM ≅ ΔEFD.
6. By CPCTC, angle NRM is a right angle.
