Answer:
n = 70
Step-by-step explanation:
n/10 = 7
Multiply each side by 10
n/10 *10 = 7*10
n = 70
Answer: 30 dominoes in total.
Step-by-step explanation:
Each line is 21 inches long.
the space between dominoes is 1 + 1/2 inches.
(assuming that the distance includes the domino itself) Now, we need at least two dominoes to see this distance,
The we have N + 1 dominoes per line, and the distance is:
N*(1 + 1/2)inches = 21 inches
If we find N, we can find the number of domineoes in each line:
N = 21/(1 + 1/2) = 14
This means that we have 14 + 1 = 15 dominoes in each line, and we have two lines, so we have 30 dominoes in total.

Answer: ( 2, -6 )
Step-by-step explanation:
rewrite y= (x-6)(x+2) in the form y=ax^2+bx+c
Y=(x-6)(x+2)
(x-6)(x+2): x^2-4x-12
y=x^2-4x-12
the parabola params are :
a=1, b= -4, c=-12
x^v=-(-4)/ 2*1
x^v=2
y^v=-16
