3x-5y =15
2x-y=-4
multiply the equation by 5 and then subtract equation 2 from equation 1
so 3x-5y =15
10x-5y =-20
-7x =35 x =-5
plug in the value of x in the second equation -10 -y =-4 - y= -4 +10 y =-6
x=-5 y=-6
Answer:
(21, 5)
Step-by-step explanation:
y = -x
y = -(-7)
y = 7
The point is reflected, so it is equidistant on both sides of the reflection line. It takes 14 units to get to the reflection line, -7 + 14 = 7 (the reflection line).
So, another 14 on the other side would be 14 + 7 = 21

Answer:
Step-by-step explanation:
We are given that 30% of California residents have adequate earthquake supplies.
a) Ramon variable X denotes the number of the california residents that have adequate earthquake insurance
B) x can take value 1 ,2 ,3 ......
C)The distribution of random variable is geometric distribution with parameter p=0.3
The pmf of geometric distribution is

D)P(X=1) or P(X=2)=P(X=1)+P(X=2)
P(X=1) or P(X=2)=
E)

F)

p is the resident who does not have adequate earthquake supplies.
p = 1-0.3 = 0.7

G)
The answer for your question is 2 × s × t × t.
I think it’s 16 but I’m not completely sure
