We have system:
y=2x+1
y=2x^2+1
To find which ordered pair is solution to this system we need to solve system for x and y.
Left sides are same so the right sides must be same too.
2x+1=2x^2+1
2x-2x^2+1-1=0
2x-2x^2=0
2x(1-x)=0
x1=0
x2=1
y1=2*0+1=1
y2=2*1+1=3
The solution are pairs (0,1) and (1,3).
Answer:
d) The data are quantitative because they consist of counts or measurements.
Step-by-step explanation:
The number of cases of flu treated at a certain hospital in different years consists in integer numbers (there cannot be 108.4 cases of flu treated in one year, just 107, 108, 109, etc).
Therefore the date are quantitative because the data consists of numbers which are counts of a certain number of individuals who were affected by the flu during different years.
Answer:
x^3 y^2
Step-by-step explanation:
combine common variables
Answer:
<h3>p(+)q=SQR(p^2+q^2)</h3>
8(+)6=SQR(8^2+6^2)
SQR(64+36)
SQR(100)
=10
Step-by-step explanation:
p + Q is equal to square root of p square + Q Square
sqr means square root
