Answer:
Step-by-step explanation:
f(x) = -8x + 20
f(-1) = -8* -1 + 20 = 8+20 =28
5 - 2[f(-1)] = 5 - 2*28 = 5 - 56 = -51
Whole Wheat = 1/6
Buckwheat = 1/8
W = whole wheat flour
B = buckwheat flour
⅔W + ½B = 4
Divide everything by 4
⅔W/4 + ½B/4 = 4/4
2/12W + 1/8B = 4/4
1/6W + ⅛B = 1
The length is 12 inches and the width is 8 inches.
Dimensions are 20 + 20 + 40 + 40
The y has to be negative but the x positive. So that leaves only (3,-4)
Hope this help!!!
Have a nice day!!!
