First make sure that one of the variable has the same coefficient in each equations.
For example lets use:
y=x+3
2y=3x-1
Since neither the y's or x's are the same, we must multiply the equations to make them the same. I am going to multiply the first equation by 2 so I can eliminate the y's.
So we get:
2y=2x+3
2y=3x-1
Then we subtract the second equation from the first to eliminate the y's. So we end up with 0=-x+4 and now we solve for x
0=-x+4
x=4
Now we plug in our x into either original to get the y-value. I am using the first
y=x+3
y=4+3
So the x=4 and y=7
Hope this helps!
Is that just the question? I can help you out but it doesn’t make any sense.
Answer:
= 100
Step-by-step explanation:
The number of visitors is modeled by the expression
Where m is the number of months after the number of visitors was measured.
We need to evaluate the above expression for m = -2.
So,
At m = -2, the value of the above expression is equal to 100.
Answer:
For the first two you are right, the last two should be 1/10 and 9/10.
Step-by-step explanation:
The probability that you win is both blue and even number happen, which is 1/5 * 3/6 = 3/30 = 1/ 10, then the probability you not win is 1- 1/10 = 9/10.
