Answer:
(3,-4) or x=3 and y= -4
Step-by-step explanation:
I'm going to solve this by substitution
We first need to get a variable by itself in one of the two equations (it doesn't matter which variable and the equation you do the work on doesn't matter either)
I'm going to solve for y in the second equation
-4x-4y=4
add 4y and subtract 4 from both sides to get
-4x-4=4y
Divide by 4 to get
-x-1=y
We can plug this value in for y into the first equation and get
4x+5(-x-1)= -8
Solve for x
4x-5x-5= -8
-x-5= -8
-x= -3
x=3
We can plug this value into one of the first two equations and solve for y
4(3)+5y= -8
12+5y= -8
5y= -20
y= -4
Therefore the solution is (3,-4) or x=3 and y= -4
Answer: they are not equal

Hi myself Shrushtee.
Step-by-step explanation:
Given,
p=0.95
n=5
1-p = q =1-0.95=0.05
a)Probability that exactly 4 of these 5 sports bikes pass final inspection =0.2036
b)Probability that less than 3 of these 5 sports bikes pass final inspection =0.0012
Please mark me as brainleist
I believe that is correct
I can't see. This is kinda blurry
