Answer:
The answer is 18 on the 7th grade, 12 on the 6th grade.
Step-by-step explanation:
3x6=18
2x6=12
18+12=30
Answer:
a monomial, a constant
Step-by-step explanation:
It has only 1 term, so it's a monomial.
Also, the term is a constant.
From that equation we know the center is: (1,-1) and the radius is three. Since the distance from the center to (0,0) is:
d^2=1^2+1^2
d^2=2
d=√2
Since d<r, √2<3, the circle intersects the y-axis two times.
So the statement saying that the circle intersects the y-axis is true.
Step-by-step explanation:
let the eqn be y = mx + b.
m = 200/(900 - 700) = 1
sub (700, 0):
0 = 700 + b
b = -700
therefore eqn is y = x - 700
