Which equations are equivalent to y = 2/3x - 4 when written in slope-intercept form? check all that apply a. 3x-2y=4 b. 2x-3y=12 c. -4(2x-3y)=-4(12) d. 2(x+6)=3y e. 2x-3y=4

The correct options are b and c.

Step-by-step explanation:

The given equation is

The slope intercept form of a linear equation is

In option a,

Divide both sides by 2.

Therefore option a is incorrect.

Similarly rewrite all equations in their slope intercept form.

In option b,

Therefore option b is correct.

In option c,

Therefore option c is correct.

In option d,

Therefore option d is incorrect.

In option e,

Therefore option e is incorrect.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
