Answer:
D
Step-by-step explanation:
Current coordinate of R : ( 1,5 )
Applying translation with rule (x,y) --> (x+1 , y-1)
Coordinate after translation ( 1 , 5 ) ==> ( 1 + 1 , 5 - 1 ) ==> ( 2 , 4 )
applying dilation with scale factor of 3 , to apply dilation multiply x and y values by scale factor which is 3
Coordinate after dilation ( 2 , 4 ) ==> ( 2 × 3 , 4 × 3 ) ==> ( 6 , 12 )
The final coordinate is ( 6 , 12 )
X² - y = -2 .................. equation 1
<u>-x + y = 4</u> .................. equation 2 from the y's we can obtain y - y = 0
the new equation will be
x² - x = 2 to for a quadratic equation make the equation equals to zero
x² - x - 2 = 0
x² - 2x + x - 2 = 0 using factorization method
x(x - 2) + 1(x - 2) = 0
(x + 1)(x - 2) = 0
x + 1=0 and x - 2=0
x = -1 or 2
subtitute x= -1 in equation 2 subtitute x= 2 in equation 2
-(-1) + y = 4 -(2) + y = 4
1 + y = 4 -2 + y = 4
y= 4 - 1 y= 4 + 2
y= 3 y= 6
the values of x are -1 and 2 . The values of y are 3 and 6
when x is -1, y is 3
when x is 2, y is 6...
Answer:
1. Equivalent
2. Not equivalent
Step-by-step explanation:
1. Equivalent because there's 4 x's that you add all together and that makes 4x
2. Not equivalent because 5x means there's 5 x's or x + x + x + x + x not only 1 x plus a number 5
