The right answer is y=5x+-5 becuase slope intercept form is coming in handy for this question. hope this helps.
Answer:
What is the question?
Step-by-step explanation:
Answer:
The answer is 6
Step-by-step explanation:
b(x) = |x+4|
b(-10) = |-10+4|
= |-6| (absolute value is always interested in +ve value)
= 6
Answer:
46
Step-by-step explanation:
I think that you could do 27-23 since then do 50-4
Answer:
b² = a² + c² - 2ac cos B
Step-by-step explanation:
The cosine rule can be use when you are given three sides of a triangle and ask to find any angle or when you are given two sides and a included angles(the angle between the two sides given) and ask to find the length of a side.
The equation Sophia can use to solve for the side length(b) of a triangle when given two length and the included angle can be expressed below. Sophia was given two sides and an included angle and was asked to find a side length b.
For sides a, b and c the cosine rule can be represented below
a² = b² + c² - 2bc cos A
b² = a² + c² - 2ac cos B
c² = a² + b² - 2ab cos C
The equation required base on your question is
b² = a² + c² - 2ac cos B
