p + 2 = 5 ==> p = 3
3p + 2 = p + 3 ==> 2p = 2 ==> p = 1
3k + 5 = 2k + 2 ==> k = -3 (niemożliwe; lewa strona wagi ma większą wagę)
2w + 10 = 4w + 7 ==> 2w = 3 ==> w = 3/2
d + 9 = 3d + 2 ==> 2d = 7 ==> d = 7/2
W drugim zadanie każda litera reprezentuje wagę jednego z obiektów. Na przykład 3k + 4 reprezentuje całkowitą wagę 3 kół i 4 ciężarów, każdy o wadze 1 kg.
Trzecie zadanie to tylko połączenie dwóch pozostałych.
I believe the answer is D
Answer:
4
Step-by-step explanation
The highest degree of a quadratic equation or polynomial always determine the number of factors or zeros that such polynomial have.'
For the polynomial 2x^4+6x-5
You can see that the leading degree is 4. Hence the polynomial will have 4 roots and factors
728 km per hour
3640 divided by 5 to find the unit rate for kilometers per hour
Answer:
C.
Step-by-step explanation:
C. (-7, 2), (-1, 3), (4,7), (7,2)
The values of x are not repeating, so this is a function, because for every x has only one corresponding value of y.
