Answer:
the answer is D (9)
Step-by-step explanation:
3(n-5)=12
3n-15=12
add 15 on both sides
3n=27
divide both sides by 3
n=9
Answer:
A:
Step-by-step explanation:
In this case it can be seen that the x values are being affected by this transformation. This means that we should look for points on f and g with the same y value but different x values. However in this case it is hard to pinpoint easy coordinates to work with. This is where process of elimination can help. We know it cant be B or C because if the dilation ratio is outside the function, the y values would be affected. That leaves it to A or D. We can see that g has shrunk from the original function. Shrinking along the x-values can be notated by the reciprocal of the factor of shrinking. In this case it looks like it shrunk down to half of the originals size. If we take the reciprocal of a half we get 2. Therefore if we plug that in we get:
Step-by-step explanation:
perpendicular bisector
AB= 17
Answer:
225.5cm and 134.5cm
Step-by-step explanation:
From the question, the width of the poster is 91cm
We divide this width into 2
= 91cm/2
= 45.5cm
We are told that the center of the wall is 180cm right from the end of the wall.
Therefore,
Left edges of the poster from the right end of the all
= 180cm + 45.5cm
= 225.5 cm
The right edges of the poster from the right end of the all
= 180cm - 45.5cm
= 134.5 cm
Therefore, if Cara hangs the poster so that the center of the poster is located at the center of the wall, the left and right edges of the poster will be 225.5cm and 134.5cm from the right end of the wall respectfully.
Answer:yes
15x times 2=30x
15x times 3= 45x
