One equivalent expression is 5 and the other is 6
We have that
the first balance indicates--------> 10 g
the second balance indicates--------> 0 g
the third balance indicates--------> 7.5 g
therefore
the <span>mass of the chick is (10+0+7.5)----> 17.5 g
the answer is
17.5 g</span>
Answer:
sales tax is $0.6
total cost is $20.60
Step-by-step explanation:
20*0.03=0.6
20*1.03=20.6
Answer:
Step-by-step explanation:
Given that:
Number of seats sold is 180 with ticket price $200.
Number of seats decreases by one when the ticket price is increased by $3.
To find:
The formula for the number of seats sold (S) when the ticket price is P dollars.
Solution:
It is linear dependency of number of seats sold, S on ticket price, P.
It can be written as:
Where 
is the constant of proportionality and
is a constant.
Now, putting the given values:
...... (2)
Subtracting (1) from (2):
Putting the value in (1):
Therefore the equation becomes:
#4
(-2,4)(-3,5)
slope = (5-4)/(-3+2) = 1/-1 = -1
point slope form
<span>y-y1 = m(x - x1)
</span>y - 4 = -(x + 2)
#5
y intercept of 3 , y = 3 or (0,3)
x intercept of -2 , x = - 2 or (-2,0)
slope = -3/2
slope intercept form
y = mx + b
y = -3/2x + 3
#6
point slope form
y = 1/2x - 4 passing thru(5,2)
y - 2 = 1/2 (x - 5)
# 7
y = 1/2x - 4
perpendicular slope = -2
passing thru (-1,4)
using point slope form
y-4 = -2(x+1)
