Answer: Check explanation.
Step-by-step explanation: Let's say the equation is 4x ≥ 32, you can mark it on the number line with a filled in dot on 8 and arrow going to the right (increasing) forever. The dot indicates that the answer could be 8, and the arrow indicates it can be more than 8. Hope this helped!
"Completing the square" is a step in the solution of quadratic equations. It can be accomplished without the guesswork or trial-and-error associated with methods like factoring, and it always leads to a solution. It is the method by which the quadratic formula is derived.
Answer:
B. Sine.
Step-by-step explanation:
We need to find the value of x which is opposite to the given angle (50 degree). Also we are given the length of the hypotenuse.
Sine = opposite / hypotenuse so we would use the sine.
Its worth committing this mnemonic to memory, which helps to find the required trig ratio:
SOH-CAH-TOA.
SineOpposite/Hypotenuse- CosineAdjacent/Hypotenuse-TangentOpposite/Adjacent.
Because you need to subtract from 10, you need to do 10-8. Then you will add 5 since you took away 5 to subtract from 10.
