Which of the following expressions are equivalent to polynomial ((6x ^ 3 * y ^ 9)(7x * y ^ 2)) - ((9x ^ 3 * y ^ 2)(3x * y ^ 9)) + (8x * y ^ 2) ^ 2 Select all that apply .

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

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

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
