Answer:
Graph the triangle at points (1,5), (1,8), and (6,8)
Step-by-step explanation:
Since the rule is (x,y) -> (y,x), that just means swapping the value of x and y.
The first point (5,1) has 5 for x and 1 for y. If you swap the values, you get 1 for x and 5 for y, or (1,5).
The second point is (8,6). If you swap x and y you get (6,8). Notice I'm not doing the inverse of each number by making them negative, just swapping the twp values.
The third point is (8,1) and if you swap x and y you should get (1,8).
The transformation rule applies to ALL points, otherwise it wouldn't look right and it wouldnt be transforming.
I hope this helps :)
Answer:
27/40
Step-by-step explanation:
Here's our data:
15 questions total
Total number of points: 100
Spelling questions are worth 5 and represented by x
Vocab questions are worth 10 and represented by y
Therefore:
x+y=15
5x + 10y= 100
So:
x+y=15
x= 15-y
5x +10y =100
5(15 -y) +10y =100
75 -5y +10y =100
75 +5y = 100
5y=25
y=5
x +y=15
x+5=15
x=10
There are 10 spelling questions and 5 vocab questions
Answer:
512cm²
Step-by-step explanation:
1/2bh*2 = 1/2(4)(10)(2)=40
Each triangle is 40
18*8=144
Each rectangle is 144
144+144+144+40+40=512cm²
3² + 3(8) + 2 - 2(5)
9 + 24 + 2 - 10
25
Hope this helps :)
