Answer:
The answer is x = 14 the more expensive scarf
Step-by-step explanation:
x + y = 25
3 + y + y = 25 (x = 3 + y)
3 + 2y = 25
2y = 25 - 3
2y = 22
y = 22/2
y = 11
x = 3 + y
x = 3 + 11
x = 14 (the more expensive scarf)
(x,y) ; (14,11)
Answer:
x^2 - 10x + 25
Step-by-step explanation:
When you find the area, you want to break it up into different parts. Therefore, one part would be a square and the other part can be a trapezoid. Start out with finding the area of a square by multiplying 6 and 6. This will get you 36. Then, subtract 6 from 21. This will get you, 15. Then use the area of a trapezoid formula, which is A=(a+b)/2 times H. The H is the heigh, the a and b are the top and bottom bases. So if you plug it into the equation, (7+15)/2 then multiply that by 6 ( which is the height). this will get you 66. If you add 66+36, it equals 102 which is the area
Answer: B. A coordinate plane with points in quadrants II and IV.
Step-by-step explanation:
Let's take the point (-1,1) as an example
The point itself is in the second quadrant
the opposite of the point is (1,-1)
This point is in the fourth quadrant
Answer:
None
since the slopes are equal, it's either infinite or none.
since the ratios of Ys and Xs is 1, 18/16 should be 1 to say we have infinite answers. since it's not, the is no solution at all.
