Answer:
(13, -3)
Step-by-step explanation:
slope = -5/7
(6,2)
m = ( y2 - y1) / ( x2 - x1 )
-5/7 = ( y2 - 2) / ( x2 - 6 )
-5 = y2 -2
+2 +2
-3 = y2
7 = x2 - 6
+6 +6
13 = x2
Check answer again by log them in:
m = ( y2 - y1 ) / ( x2 - x1 )
m = ( -3 - 2 ) / ( 13 - 6 )
m = -5 / 7
I hope this helps!
Question 4:
OOOOOHHH a breakthrough! I was confused when I read this question but now I get it!
Okay when dividing this equation I would do this
5^4
25
Since 25 is 5 x 5 I would mark it as 5^2, and then I can subtract!
5^4
5^2 =
5^2
If you do it like this then it would be the first choice.
Answer:
c = 20d + 15
Step-by-step explanation:
answer choices may help if the answer is not one of the choices; but here is the answer that it should be:
20 dollars per day is 20 times the length of rental.
15 is a cost that is added and does not change.
c = the total cost therefore:
c = 20d + 15
A = l*w
A = 4*12 = 48cm^2
The area of the rectangle is 48cm^2 (cm squared)
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
