Given:
To find:
The value of x.
Solution:
We have,
The corresponding parts of similar triangles are proportional.
On substituting the values, we get
Subtract 
from both sides.
Therefore, the value of x is 3 units.
The ship is 25.54 miles away from the lighthouse.
Answer is the last choice
2a-4/1= -a-1/a-4
Cross multiply
(2a-4)(a-4)= -(a-1)
2a^2-8a-4a+16= -a+1
Bring right to left sign change signs
2a^2-8a-4a+16+a-1=0
Combine like terms
2a^2-11a+15=0
a= 2 b= -11 c= 15
Use quadratic formula
-b+-sq rt of b^2-4ac. Divided by 2a
-(-11) +- 11^2-4(2)(15) divided by 2(2)
11+-sq rt 121-120 divided by 4
11+1 /4. 11-1/4
12/4. 10/4
3. , 5/2
Bike is rented for $9/hour and scooter can be rented for $10/hour. So for the bike it would be 9b (9xb) and the scooter is 10s (10xs) for the total cost of both of them the answer is 9b+10s
Answer:
solutions
Step-by-step explanation:
Another term for the roots or x-intercepts of the standard-form quadratic equation is "<em>solutions</em>." These are the values of x that make the equation true.
