Evaluate the function
pls help!!

h ( -6 ) = -13228

Step-by-step explanation:

h ( x ) = -10x^(4) - 9x^(2) - 8x + 8

evaluate when, x = -6

Substitute in -6, for x,

-10(-6)^(4) - 9(-6)^(2) - 8(-6) + 8

= -10(1296) -9(36) -8(-6) + 8

= -12960 - 324 + 48 + 8

= -13284 + 56

= - 13228

the answer to this question is in the pic

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
