Answer:
(x, y)→(x − 9, y − 3)
Step-by-step explanation:
We have given Hexagon DEFGHI is translated on the coordinate plane to create hexagon D'E'F'G'H'I':
We write the translation one by one:
D (3, 5)
D' (-6, 2)
that translates to: (x - 9, y - 3), because that is for passing from D to D':
(3 - 9, 5 - 3) = (-6, 2)
Now for E (7,5)
E' (-2,2)
that translates to: (x - 9, y - 3), because that is for passing from E to E':
(7 - 9, 5 - 3) = (-2, 2)
Now for F(8,2)
F' (-1, -1)
that translates to: (x - 9, y - 3), because that is for passing from F to F':
(8 - 9, 2 - 3) = (-1, -1)
therefore if it is true for D and D', E and E', F and F' then it has to be true for all others for the rule to be true, so the rule represents the translation of hexagon DEFGHI to hexagon D'E'F'G'H'I' is (x, y)→(x − 9, y − 3) ....
X-y=3
x=3+y
3+y+2y=8
3y=5
y=5/3
x=4 and 2/3
Answer:
y= -100 x= 100
Step-by-step explanation:The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m(x-a) is essentially different from the other two forms, and means slope m and x-intercept (instead of y-intercept) a.
Answer:
Step-by-step explanation:
<em>Vertical angles are equal as per definition.</em>
- ∠E and ∠F are vertical angles
- m∠E = 9x+12 and m∠F = 3x+24
- x = ?
<u>Solution</u>
- 9x+12 = 3x+24
- 9x - 3x = 24 - 12
- 6x = 12
- x = 2
Answer:
" -3 y + x"
Step-by-step explanation:
There seems to be a term in the variable "y" and another one in the variable "x". The coefficient of the term in y is "-3" which means that the term in the variable "y" should read: = -3y".
The coefficient of the term in x is "1", which means that this term should read: "1 x", or simply "x".
There is no "constant" term, which means that there is no term with just a numerical value (and no letters).
Therefore, the most likely expression the person could have written is: " -3 y + x"
