To find the inverse we swap y and x and solve for y:
x = 9y + 15
x - 15 = 9y
y = (x-15)/9

<u>Answer:</u>
BC = 18 cm
<u>Step-by-step explanation:</u>
As we can see from the diagram:
AB + BC + CD = AD
⇒ 10 cm + BC + 11 cm = 39 cm
⇒ BC + 21 cm = 39 cm
⇒ BC = 39 cm - 21 cm
⇒ BC = 18 cm
Answer:
x<-1
Step-by-step explanation:
We multiply by -1 of both sides and change the sense of inequality:
(-1)*(-3(x-5))>(-1)*18
3(x-5)<-18
3 passes by dividing
x-5<-18/3
x-5<-6
5 goes by adding:
x<-6+5
x<-1
100 days because 40 divide by 4 = 10 10 x 10 =100
the answer is D
the square root of 6 because it cannot be written as a fraction
