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:
x = 36
Step-by-step explanation:
Rearrange the equations before solving simultaneously
4y = -5x - 28
2y = 7x - 24
now subtract
4y - 2y = 2y
5x - 7x = -2x
-28 - - 24 = -4
put these values together.
2y - 2x - 4.
2y = 2x + 4
y = 2x + 4 / 2
y = x + 2
substitute this into one of the 1st equations in the question.
5x = -4(x + 2) + 28
5x = -4x + 8 + 28
5x = -4x + 36
9x = 36
x = 4.
Answer:
A. China
Step-by-step explanation:
Answer:
1=z
Step-by-step explanation:
Multiply 15 to the parenthesis.
12=15z-15/5
12=15z-3
Add 3 to both sides
15=15z
Simplify
1=z
Answer:
Let the truck is driven X miles per day
Charges of company A will be = 90+0.4X
Charges of company B will be =30+0.7X
Let us find out value of X when charges of both companies are same
which means that 90+0.4 X= 30+0.7X
90-30 = 0.7X-0.4X
60 = 0.3X
60/0.3 = X
X= 200
The charges of both companies will be same if truck is driven 200 miles per day
Company A will have better deal if truck is driven more than 200 miles per day ( because per mile rate of company A is less than company B)
