Answer:
x = 10
y = 20
Step-by-step explanation:
7x + 90 + 20 = 180
7x = 70
x = 10
5x + 2y = 90
50 + 2y = 90
2y = 40
y = 20
Answer:
Its degree can be at least 1970
Step-by-step explanation:
for each root of the form √q, where q is not a square, we have a root -√q. Therefore, we need to find, among the numbers below to 1000, how many sqaures there are.
Since √1000 = 31.6, we have a total of 30 squares:
2², 3², 4², ...., 30², 31²
Each square gives one root and the non squares (there are 1000-30 = 970 of them) gives 2 roots (one for them and one for the opposite). Hence the smallest degree a rational polynomial can have is
970*2 + 30 = 1970
Answer: speed = 17m/s
time taken = 3min = 3 x 60 = 180 seconds (1min = 60sec)
distance = ST
= speed x time
= 17 x 180
= 3060m

Answer:
B
Step-by-step explanation:
14x - 3x + 11 = -22
-11 -11
14x - 3x = -33
11x = -33
/11 /11
x = -3
