Answer:
n = 20
Step-by-step explanation:
Cross multiplication would result in:
16 * n = 8 * 40
16n = 320
n = 320 / 16
n = 20
Therefore <u>the value of "n" in this proportion is 20.</u>
Hope this helps!
I need to see the rest of the problem in order to solve it.
Answer:
One month of gameplay costs $18.75
Step-by-step explanation:
( 250 - 50 × 2 ) ÷ 8 = 18.75
The
= 5, which is a real number, a rational number, a whole number, an integer, and a natural number.
The answer is
B: N, W, Z, Q, R
Step-by-step explanation:
ax^2+bx+c=0
a=leading term
ok so if the leading term is positive then opens up and has a <u>min</u>
if leading term is negative then opens down and has a <u>max</u>
leading term is positive
1x^2+8x
it has a min
to complete the square, move c aside take 1/2 of b and square it
b=8
8/2=4
4^2=16
now add that to both sides
x^2+8x+16+6=0+16
factor perfect square
(x+4)^2+6=16
subtract 6
(x+4)^2=10
subtract 10
(x+4)^2-10=0
vertex aka min or max is (h,k) when ou have
y=a(x-h)+k
h=-4
k=-10
