Explanation:
80=N+D
7.80=0.05N + 0.1D
D=80-N
7.80=0.05N + 0.1(80-N)
7.80=0.05N + 8 - 0.1N
0.1N + 7.80 = 8 + 0.05N
0.05N = 8-7.80
0.05N = 0.2
N= 4
I think the answer is horizontal translation of 4 units left and a vertical translation of 8 units up.
Answer:
$3.50
Step-by-step explanation:
to find the range you take the highest number and the lowest number and subtract them
so with that, let us do just that-
$5.75, $3.75, $3.25, $2.25
$5.75-$2.25
=$3.5
and since we're dealing with money we must add a '0' to the end of the decimal- $3.50
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!
Answer:
I think it is the first one
Step-by-step explanation:
Answer:
X= 1 AND 13
Step-by-step explanation:
x2+14x = -13
by completing the square method
you add the square of half the coefficient of b to both sides
which is (14/2)^2
x^2+14x+(7^2) = -13 +(7^2)
x^2 + 7^2 = -13 + 49
x^2 + 7^2 = 36
(x + 7)^2 = 36
find the square root of both sides
(x+7) = + or - 6
x=7-6 ; 1
or
x= 7+6 ; 13
