Shen rented a truck for one day. There was a base fee of $14.99, and there was an additional charge of 88 cents for each mile driven. Shen had to pay $268.43 when he returned the truck. For how many miles did he drive the truck?

288miles

Step-by-step explanation:

Given data

Base fee= $14.99

Additional charge= $0.88

let the number of miles be x

and the total charges for x miles be y

hence the expression for the total is

y=14.99+0.88x1

when y=268.43

let us substitute into the eqn 1 to find x

268.43=14.99+0.88x

268.43-14.99= 0.88x

253.44=0.88x

x= 253.44/0.88

x= 288 miles

Hence the number of miles is 288miles

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
