In inverese, when x increases, y deceases, when x decreases, y increses

we see that x increases for all choices

therefor the y values of the answer should be decreasing

first one is increasing, wrong
second is decreasing
third is also decreasing
fourth is increasing


look at second and third

remember
xy=k for inverse
so just solve for k for each and see if it is valid

second
1,60
(1)(60)=k
60=k

2,30
(2)(30)=60
60=60
true

therefor this is nswer

The ratio of the circumference to the diameter is defined as pi
pi=circumference/diameter
that is how they got pi
in this question it woul be 15.7/5 which would be 3.14,





c=2pir
a=pir^2

c=2pir=16pi
divide both sides by 2pi
r=8

a=pir^2
a=pi8^2
a=pi64
a=64pi in²

-2.3 + 10.8 + (-8.4)
spayn [35]

Answer:

.1

Step-by-step explanation:

Try and take it step by step.

-2.3 + 10.8 + (-8.4)

First let's rearrange and combine the negatives.

-2.3 + (-8.4) + 10.8

-2.3 + (-8.4) = - 10.7

Let's rewrite

10.8 - 10.7  and solve!

10.8 - 10.7 = .1

How do I solve for x?
zheka24 [161]
3.) 5x-6=0, Add 6 to either side -> 5x=6, divide each side by 5 -> x=6/5 ---- 4.) x+y/3=5, multiple each side by 3 -> x+y=15, move y to the other side -> x=-y+15
