Which of the following has a slope of -3 and a y-intercept of -4 ? (a) y = -3x + 4 (b) y = 3x + 4 (c) y = 3x - 4 (d) y = -3x - 4

Letter (D), or y = -3x - 4

Step-by-step explanation:

A slope of -3 should be self explanatory, and y intercept is determined by the b value in the form y = mx + b. Since b is negative, we are looking for -4. Therefore, your answer is (D).

Hope this helps!

i dont know

step-by-step explanation:

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
