See the attached figure

A(4,8) B(0,7) C(4,3)
<span>the line of reflection is x=5
</span>
the reflection is (x,y)-------------------> (10-x,y)
therefore
A(4,8)-----------------> A1(10-4,8)------> A1(6,8)
B(0,7)-----------------> B1(10-0,7)------> B1(10,7)
C(4,3)-----------------> C1(10-4,3)------> C1(6,3)

The expression (3x^2)^4/9x^3 is equivalent to which other expression

maksim [4K]

$\frac{(3x^2)^4}{9x^3}=\frac{3^4x^{2\cdot4}}{9x^3}=\frac{81x^8}{9x^3}=9x^{8-3}=9x^5$

If 30% of John's photographs were perfect, but 210 photographs were not perfect, then how many photographs were there in all?

loris [4]

If 30% were perfect, 70% were not perfect. So we know that 70% of the total number of photographs is 210.

p(70/100)=210 multiply both sides by 100

70p=21000 divide both sides by 70

p=300

So there are 300 photographs in all.
