Semester 1:
let the number of students in the art class be 2a, and the number of the students in the gym class be 7a. (check: the ratio is 2a:7a = 2:7)
so the total number of students is 9a.
semester 2:
the 9a students are go to the art class and gym class at a a ratio of 5: 4,
so 5a students go to the art class, and 4a students go to the gym class.
<span>75 students are in art class in second semester means that 5a=75,
so a=75/5=15.
In the 1st semester the number of students was:
art class: 2a=2*15=30
gym class: 7a=7*15=105</span>

In geometry, transformation involves changing the position and/or size of a shape.
<em>The transformation that will change the size of ABCD is dilation.</em>
There are four transformations in geometry:
- Translation
- Reflection
- Rotation
- Dilation
Of all types of transformation, dilation will change the size of the shape,
The new shape will either be enlarged or reduced
<em>Either ways, the size of the shape will be altered.</em>
<em>When the size is altered, the perimeter will not remain the same.</em>
<em />
Hence. dilation will change the perimeter of ABCD.

Answer:
C. x³+10x²−5x+5
E. 7x⁵+4x²
F. x+8
Step-by-step explanation:
The graph they described should look something like the one i drew below.
So all you have to do is look at the number with the highest exponent.
If the exponent is an odd number and the x is positive then that function will have an end behavior like the picture i posted.
x³ is good
-x³ is bad because of the negative sign
x² is bad because exponent is even
x⁷ is good
123x¹ is good
