Answer:

7x - 5 = 11

Step-by-step explanation:

To solve for x, substitute y = -5 into the equation 7x + y = 11.

This becomes 7x + (-5) = 11 or 7x - 5 = 11.

Part A: Abe rented a bike at $36 for 5 days. If he rents the same bike for 8 days, he has to pay a total rent of $48.
lawyer [7]
(5,36)(8,48)
slope = (48 - 36) / (8 - 5) = 12/3 = 4

y = mx + b
slope(m) = 4
(5,36)...x = 5 and y = 36
now sub and find b
36 = 4(5) + b
36 = 20 + b
36 - 20 = b
16 = b

equation is : y = 4x + 16.....in standard form : 4x - y = -16 <==
=======================
function notation : f(x) = 4x + 16
=======================
x axis will be ur hrs....I would label them at intervals of 1
y axis will be total cost of renting the bike......as far as the intervals...not sure how to label them.....sorry....I wanna say intervals of 2...but am not sure

y = 4x + 16
slope = 4
y int = (0,16)
x int = (-4,0)

so start at (-4,0)....and since ur slope is 4, go up 4 and to the right 1...keep doing this and u will cross the y axis at (0,16)

The sum of two consecutive intergers is -29. list tge number from smallest to largest
yawa3891 [41]

Hello from MrBillDoesMath!

Answer:

-15, -14


Discussion:

Let "n" be the first of the two consecutive integers . Per the Question

n + (n+1) = -29  =>

n + n + 1 = -29 =>

2n +1 = -29 =>

2n = -29 -1 =>

2n = -30 =>

n = -15,

Hence n = -15 and n+1 = -15 +1 = -14


Thank you,

MrB
