Pls is easy but idk how to do it :/

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

For

y = 8 - 3x ← in slope- intercept form

with m = - 3 and c = 8

Kanika made the error of mixing up these values

If she had expressed the equation as y = - 3x + 8 she may have got the correct values for m and c.

(a)

y = 5x + 8 → m = 5 and c = 8

(b)

y = - x + 2 → m = - 1 and c = 2

(c)

y = 3x → m = 3 and c = 0

(d)

y = 7 - x → m = - 1 and c = 7 ( think y = - x + 7 )

(e)

y = x + 6 → m = 1 and c = 6

(f)

y = 9 - 2x → m = - 2 and c = 9 ( think y = - 2x + 9 )

(g)

y = 4 + x → m = 1 and c = 4 ( think y = x + 4 )

(h)

y = - 3x - 7 → m = - 3 and c = - 7

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
