Slope is equal =
- coefficient of x / coefficient of y
slope = -6/12 = -1/2
D option is correct
You have to put the numbers in order and find the middle value so in this case it's-
2, 4, 4, 5, 6, 7, 8, 8, 8
The answer is $6
The ratio 4 to 7. would be 12 and 21
Answer:
The 9th term would be 10.
Step-by-step explanation:
Each of the odd terms is 2 more than the previous. We do not even need to look at the even terms to find the 9th one.
2, odd, 4, odd, 6, odd, 8, odd, 10
Answer: 14x^2-93xy+60y^2 Hope that helps!
Step-by-step explanation:
1. Expand by distributing terms
(20x-12y)(x-4y)-(3x-4y)(2x+3y)
2. Use the Foil method:(a+b)(c+d)= ac+ad+bc+bd
20x^2-80xy-12yx+48y^2-(3x-4y)(2x+3y)
3. Use the Foil method : (a+b)(c+d)= ac+ad+bc+bd
20x^2-80xy-12yx+48y^2-(6x^2+9xy-8yx-12y^2)
4. Remove parentheses 20x^2-80xy-12yx+48y^2-6x^2-9xy+ 8yx+12y^2
5. Collect like terms (20x^2-6x^2)+(-80xy-12xy-9xy+8xy)+(48y^2+12y^2)
6. Simplify.
And your answer would be 14x^2-93xy+60y^2
