The inequality 2x+2≤x+4≤3x+4 means that x is in the closed interval [a, b]
where a is and b

Step-by-step explanation:

2x+2≤x+4≤3x+4

means : 2x+2≤x+4  ...(1) and x+4≤3x+4

(1) : 2x-x≤4-2   so : x≤2(*)

(2) :3x+4 ≥x+4     3x-x ≥ 0    so: x≥0 (**)

by (*) and (**) : 0≤x≤2   so : A=0  and B = 2

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
