-3x + 6y + 5 = -7
<u> -5 -5</u>
-3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
<u>6y</u> = <u>-12 + 3x</u>
6 6
y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
-3x - 12 + 3x = -12
-3 + 3x - 12 = -12
0x - 12 = -12

(x, y) = (0, -2)
Answer:
5y+3x=123
Step-by-step explanation:
(x1,y1)=(1,24), m=-0.6
y-y1=m(x-x1)
y-24=-0.6(x-1)
y-24=-6/10(x-1)
10(y-24)=-6(x-1)
10y-240=-6x+6
10y+6x=6+240
10y+6x=246
divide by through by 2
5y+3x=123

Answer:
The probability of getting exactly two read marbles is P = 0,003456%
Step-by-step explanation:
So, each of the following sequences are the desired results(I will use R for a red marble and G for a green marble).
S(1) = R-R-G-G
S(2) = R-G-R-G
S(3) = R-G-G-R
S(4) = G-R-R-G
S(5) = G-R-G-R
S(6) = G-G-R-R
In all, considering there are replacement, there can be 10*10*10*10 = 10000 total sequences, so the probability of getting exactly two read marbles is
P = \frac{P(S(1)) + P(S(2)) + P(S(3)) + P(S(4)) + P(S(5)) + P(S(6))}{10000}
where
P(S(1)) = P(S(2)) = P(S(3)) = P(S(4)) = P(S(5)) = P(S(6)) = (0.4)^{2}*(0.6)^{2} = 0.16*0.36 = 0.0576.
The probability of getting exactly two read marbles is
P = \frac{6*0.0576}{10000} = 0,003456%
