The answer is (2,0)
Explanation
So I’m gonna use substitution to help me solve this problem. I’m gonna solve for x.
X-y=2
+y. +y
X= y + 2
Now that we have solved for x we are going to plug it into the first equation!
Shown like this
Y+2 - 10y = 2
Then we solve it as a normal problem
So first we combine light terms
-9y+2=2
Then we isolate the variable
-9y+2=2
-2. -2
-9y = 0
Then we divide by -9 on both sides
-9y /-9 = 0 / -9
Y = 0
Now that we solved for y we plug it into one the equations to get the x value!
X - 0 = 2
X=2
The solution is (2,0)
I hope this helped you! Pls mark as brainliest
Answer:
All positive real numbers
Step-by-step explanation:
Given
The model can be represented as:
Required
Determine the domain
This means that we list out possible values of x.
If x represents time, then it is impossible for x to be negative.
This implies that x can take any value as long as it is greater than or equal to 0.
<em>Hence, the domain is all positive real numbers</em>
Answer:
Step-by-step explanation:
Well since we know 2 out of 10 as a fraction is 2/10, we must convert it into a percentage. Here's how. You can first reduce this fraction:<span><span>2/10 reduced</span></span>
<span><span>=<span>1/5</span></span><span>=</span></span>
<span><span>=1÷5</span><span>= </span></span><span><span>0.2 </span></span>Converting our number to a percentage:<span>=0.2×100=20<span>%
The anwer is 2/10 = 20%. Hope this helps! :)</span></span>
