Answer:
let missing number be x
63/21=9/x
or. 63x=9*21
or 63x=189
or x=189/63
or x=3
. missing number of this proportion=3
Y = 3x + 1
y = 4x – 7
3x + 1 = 4x - 7
x = 8
y = 3x + 1 , x = 8 ,
y = 3(8)+ 1
= 25
Answer : (8,25)

Angl G = angle I because of alternate interior angle theorem
the triangle JHG is congruent to the triangel JFI because the corresponding angles F and J equal with J and H in the other triangle and the sides between them are equal FJ and HJ
therefor GJ = IJ because of the congruence
Answer:
Option a is right.
Step-by-step explanation:
Parent funciton is
The new graph is
Since there is no change for x, there is no horizontal shift.
BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.
Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2
Option a is right
i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.
