Answer:
None of the above ? （the equation should be y=12）
Step-by-step explanation:
the line parallel to line y=40-1=39 means it's a horizontal line. Which means it's y coordinate is also a constant. Since it pass through （2,12）,it means the constant of y is 12.
If you flipped the graph y=x^2+2x-2 vertically, you would get the graph y=-(x^2+2x-2) this is True.
Answer:
Solution: C) 7.815
Hint: From Chi-square table with (k-r-1)=(6-2-1) = 3 d.f the critical value = 7.8147
Answer:
644 cm^2
Step-by-step explanation:
10*7*2+12*7*2+12*10=140+168+120=428
10*12-3*3=111
428+111=539
8*3*4+3*3=96+9=105
539+105=644
Answer: 2w + 4 = 35
Step-by-step explanation:
Carl's two checked bags and his one backpack together weigh 35kg.
Carl's two checked bags have equal weight so both their weight can be denoted as 2w.
Equation is;
2w + 4 = 35
If you were to solve;
2w + 4 = 35
2w = 35 - 4
w = 31/2
w = 15.5kg
