Answer:
Option b is the correct answer as both the equations are true for given solution.
Step-by-step explanation:
Given equations are:
-0.1x-0.3y=1.2
0.2x-0.5y=2
We can observe each graph and find the point that is the solution and put the point in the equations to know if that point is the solution
<u>For option A:</u>
(0,4)
Putting x=0 and y = 4 in both equations
This is not the correct answer as both equations are not true with this solution
<u>For Option B:</u>
(0,-4)
Putting x = 0 and y = -4 in both equations
Both equations are true for (0,-4) hence it is the solution of the system.
<u>For Option C:</u>
(4,0)
Not true for both equations
Hence,
Option b is the correct answer.
You cant parentheses in that sentecne
<span>Find the inverse of the given function.
f(x) = -1/2√x + 3, x ≥ -3
I will have to assume that you meant f(x) = -(1/2)sqrt(x) + 3. If you actually meant f(x) = -(1/2)sqrt(x+3), then obviously the correct result would be different.
1. Replace "f(x)" by "y:" y </span>= -(1/2)sqrt(x) + 3
2. Interchange x and y: x = -(1/2)sqrt(y) + 3
3. Solve for y: x-3=-(1/2)sqrt(y), so that 2(3-x)= sqrt(y) and y=+sqrt(2[3-x])
4. Replace "y" with
-1
f (x) = sqrt(2[3-x])
Here, there are restrictions on x, since the domain of the sqrt function does not include - numbers. The domain here is (-infinity,3]
The x shows how they are meeting with the things to be with
Answer:
q+4 + d-3 + n ; first
Step-by-step explanation:
first :q quarter d dimes n nickels
then: q+4 quarter d dimes n nickels
then: q+4 quarter d-3 dimes n nickels
so you have q+4 + d-3 + n
first is the only option that has division the other involve subtraction
