Answer: F
Step-by-step explanation:
- This does not have infinitely many solutions (adding the equations, we get a fixed value of x)
- This has no solutions (the left hand sides are the same but the right hand sides have different values)
- This has one solution (the first equation givess a fixed value for x)
- This has no solutions (same reason as 2)
- This has one solution (same reason as 3, just the second equation instead of the first)
- This has infinitely many solutions (multiplying both sides of the top equation by -2 gives the bottom equation).
Answer:
x = 50
m∠D = 150°
m∠F = 30°
Step-by-step explanation:
- supplementary angles are two angles whose sum is 180°
∠D + ∠F = 180°
3x + x - 20 = 180
3x + x = 180 + 20
4x = 200
x = 200/4
x = 50
D = 3*50 = 150
∠D = 150°
F = 50 - 20 = 30
∠F = 30°
Answer:
21.25 euros for the shirt and 54.4 euros for the pants.
Step-by-step explanation:
To find the value after the discount, we just need to subtract the inicial price by the discount:
Final price = Inicial price - discount * inicial price.
So, for the shirt, we have:
Final price = 25 - 0.15 * 25 = 21.25 euros
For the pants, we have:
Final price = 64 - 0.15 * 64 = 54.4 euros
So we will pay 21.25 euros for the shirt and 54.4 euros for the pants.
Answer:
the answer is c, greta could also have sent the payment by making a transfer online however sending a check is safer then sending cash
Step-by-step explanation:
If you know the derivative of some function , you can tell exactly who is, up to an additive, constant term. In fact, knowing , you have
In your case, we have
So, the integral is almost immediate:
So, up to some constant additive term, our function is
To fix this constant, we know that the function passes through the point (6,10), so we have
And so our function is
If we want to know when this function equals 6, we simply have to ask and solve for x, so we have
