Answer: down there
Step-by-step explanation:
When solving a radical equation, it is important to always check your answer by substituting the value back into the original equation. If you get a true statement, then that value is a solution; if you get a false statement, then that value is not a solution.
The sum of the digits of a two-digit number is 9. if the digits are reversed, the new number is 27 more than the original number. find the original number.
Answer:
The answer to your question is SV = 32
Step-by-step explanation:
Data
T = mid point
ST = x + 4
TV = 2x - 8
SV = ?
Process
1.- If T is the mid point of SV, that means that the distance from ST to SV is the same.
ST = TV
2.- Substitution
x + 4 = 2x - 8
-Solve for x
x - 2x = -8 - 4
-Simplifying
-x = -12
-Result
x = 12
3.- Find the length of SV
SV = ST + TV
SV = x + 4 + 2x - 8
SV = 12 + 4 + 2(12) - 8
SV = 16 + 24 - 8
SV = 40 - 8
SV = 32
I assume you mean, that an angle and two sides are known.
A formula that can be used for irregular triangles is the cosine rule.
'b' and 'c' must be sides that are beside the angle 'A' (angle opposite 'a').
The correct answer is The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.
Hope this helped! :)
