Answer:
Domain is: 0 ≤ n ≤ 75 where n is an integer
Step-by-step explanation:
Step-by-step explanation:
1. 10x-7=5x+3; ⇒ 5x=10; ⇒ x=2. If x=2, then
2. QS=10*2-7=14;
3. SR=5*2+3=13;
4. m(∠PSR)=15*2+42=72°;
5. m(∠PSQ)=180-m∠(PSR)=180-72=108°.
Answer: 0.05%
-------------------------------------------
Work Shown:
To go from percent form to decimal form, move the decimal over 2 spots to the left. Think of 2% as 2.0%
2% = 0.02
2.5% = 0.025
Multiply the decimal form of each percentage
0.02*0.025 = 0.0005
Convert that result to a percentage. Move the decimal 2 spots to the right
0.0005 = 0.05% is the probability both break down
Note: This multiplication rule only works if the two events are independent.
Answer:
5. A) two solutions
6. one solution
Step-by-step explanation:
5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:
b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number
When the discriminant is positive, there are two real solutions.

6. The equation factors as ...
0 = 3(x +3)^2
This will have one real solution at x=-3.
