Y is inversely proportional to 7I+x.
When x = 8, y = 2.
Find y when x= 15.

I am taking 7I+x to  mean 71+ x.

 y=1.837

Step-by-step explanation:

Step 1

Let y is inversely proportional to 7I+x be  mathematically be written as

y ∝ 1/7I+x

Introducing our proportionality of constant , K we have that

y ∝ 1/7I+x

y =K 1/7I+x

y= K/ 7I+xh

Step 2

so when x= 8, and y =2,  k becomes

y= K/ 7I+x

k=  y x (7I+x)

=2 x (71 + 8)

2x 79

=158

 when x= 15, y =?

y= K/ 7I+x

y= 158/  71 + 15

y=158/86

y=1.837

answer: f true

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
