Let a = longest side      <em> (Establishing labels)</em>
let b = shortest side
let c = third side

P = 14.5                <em>     (Given)</em>
a = 6.2
b = 1/2(a)

P = a + b + c
P = 6.2 + 3.1 + c        <em>(Fill in given info in equation)</em>

P = 9.3 + c                <em>(Simplify)</em>

14.5 = 9.3 + c           <em>(Simplify)</em>

c = 14.5 - 9.3           <em>(Solve)</em>
c = 5.2

Hope this made sense!

given that (y+2) (y+3) and (2y^2+1) are consecutive terms of an arithmetic progression, find the possible value of y​
mafiozo [28]

Answer:

<em>-3/2 and 1</em>

Step-by-step explanation:

Given the  arithmetic sequence  (y+2) (y+3) and (2y²+1), the common difference is gotten by taking the difference in their terms. For example if we have 3 terms T1, T2, T3... the common difference d = T2-T1 = T3-T2

From the  sequence given;

T1 = y+2, T2 = y+3 and T3 = 2y²+1

d = y+3-(y+2) = 2y²+1- (y+3)

open the parenthesis

y+3-y-2 = 2y²+1- y-3

1 = 2y²+1- y-3

1 = 2y²- y-2

2y²- y-2-1 = 0

2y²- y-3 =0

Factorize the resulting expression

2y²- y-3 =0

2y²- 2y+3y-3 =0

2y(y-1)+3(y-1) = 0

(2y+3)(y-1) = 0

2y+3 = 0 and y-1 = 0

2y = -3 and y =1

y = -3/2 and 1

<em>Hence the possible values of y are -3/2 and 1</em>

Answer:

y=55x

given y=385

x=gallons of gas = 385/55 = 7 gallons

inverse function

y=55x

change x to y and y to x

x=55y

y=x/55

inverse function is x/55
