The fourth coordinate point would be at (1, 1). If you look at the graph, it's easy to see which point is missing. You can also tell by looking for the x and y values that don't repeat, since this is a rectangle. -6 is an x-value for two coordinate points, but 1 is an x-value for only one. 10 repeats as a y-value in two coordinate points, but 1 only appears once.
Answer:
Capital: 2 400
Tasa: 5% = 5/100 = 1/20
Tiempo: 4 años
A) Interés = capital*tasa*tiempo
Interés = 2400*(1/20)*4
Interés = 480 soles
B) Interés = Capital*((1 + tasa)^tiempo+1)
Interés = 2400*((1 + 1/20)^4 + 1)
Interés = 2400*((21/20)^4 + 1)
Interés = 2400*(194 481/160 000 + 1)
Interés = 2400*(354 481/160 000)
Interés = 5 317,215Step-by-step explanation:
Looking at the problem, you can come up with an equation for the consecutive numbers.
If we expand the second term:
Combine like terms:
You can reduce this by dividing both sides of the equation by two:
And we transpose 170 to get a standard quadratic form that the right side will be zero:
Then factor the left side:
Find out the values of x that makes each factor = 0
x + 14 = 0
x = -14
We can eliminate the negative symbol because the problem is asking for positive even integers.
and;
x - 12 = 0
x = 12
Now we can say that the first positive integer is 12 and the second one is 14
Hi!
You need to multiply to remove the variable from the denominator.
The answer is m=-9
