Answer: 3x-5y=-9 is simplified to y=3/5x+9/5
x+2y=8 is simplified to y=-1/2x+4
Answer:
52 cm^2
Step-by-step explanation:
Solve by splitting the figures into 2 parts and finding their areas separately:
Rectangle:
8 × 5 = 40
Triangle:
1/2 × b × h = 1/2 × 8 × 3 = 4 × 3 = 12
Total: 40 + 12 = 52
The correct option regarding whether the requirements for a hypothesis test are satisfied is:
D. The conditions are satisfied. The samples are random, and each sample has at least 5 successes and 5 failures.
<h3>What are the conditions for an hypothesis test?</h3>
There are two conditions:
- The samples should be random.
- Each sample should have at least 5 successes and at least 5 failures.
These two conditions are satisfied for this problem, hence, researching this problem on the internet, option D is correct.

X+ 1/x= 5
⇒ (x+ 1/x)^2= 5^2
⇒ (x+ 1/x)^2= 25
⇒ x^2+ 2(x)(1/x)+ 1/x^2= 25
⇒ (x^2+ 1/x^2)+ 2*1= 25
⇒ x^2+ 1/x^2= 25 -2
⇒ x^2+ 1/x^2= 23
The final answer is 23~
Y = 2x - 6 => slope is 2
For perpendicular lines, m2 = -1/m1
Slope of the required line is -1/2
Required equation is (y - 3)/(x - 0) = -1/2 => y - 3 = -1/2 x => y = -1/2 x + 3
