Answer:
x=7
y=2
Step-by-step explanation:
10 + 2x = -2y ➡y = -5-x
replace y with -5-x in the first equation
-5-x-x = 9➡ -2x-5 = 9 ➡-2x = 9+5 ➡ x = -7
now use this information to find value of y
y - (-7)=9 ➡y = 2
Answer:
-3/5
Step-by-step explanation:
If two events A and B are independent, then P(A)*P(B) = P(A∩B).
P(A) is the probability of being blonde.
P(B) is the probability of having blue eyes.
P(A∩B) is the probability of being blonde with blue eyes.
P(A)*P(B) = (20/50)*(22/50) = 440/2500 = 22/125.
P(A∩B) = 8/50.
These two probabilities are not equivalent; 22/125=0.176, while 8/50=0.16. Our answer is D.
Answer:
No
Step-by-step explanation:
As, if we try to simplify 18/32, it will be 9/16
So obviously 9/16 is not equal to 3/5
Here 3 x 6 = 18
5 x 6 = 30
So we will get 18/30, not 18/32
Answer:
Intersect: (4 4/7 , 2 6/7)
Step-by-step explanation:
A: slope (m)= (-10-8) / (-9 - 10) = 18/19
Equation: y-8 = 18/19 * (x-10)
18x -19y = 28 (1)
B: slope (m) = (12 - -2) / (0 - 7) = -2
equation: y-12 = -2 *(x - 0)
2x + y = 12
38x + 19y = 228 (2)
(2) + (1): 56x = 256 x = 4 4/7
y = 12 - 2x = 12 - 64/7 = 2 6/7
