Answer: 12 ÷ 1 3/5
The problem is asking us to find how many days food would last. Since the food shelter uses 1 3/5 each day, the 12 bags of food would be split into 1 3/5 they use each day.
Answer: The lines through the pairs of points are perpendicular.
Step-by-step explanation: The lines when graphed do not have the same slope so they can not be parallel. However, when graphed the points (-3, 5) and (-1, 0) goes through the midpoint of the points (-3,1) and (2,3) meaning that the above points are perpendicular! Hope this makes sense and helps.
<span>The correct option is: A. f(x) = 4sin(x − π/2), because:
</span>
1. When you evaluate x=π/2 in the function f(x) = 4sin(x − π/<span>2), you obtain:
</span>
f(π/2) = 4sin(π/2− π/2)
f(π/2) = 4sin(0)
f(π/2) = 4(0)
f(π/2) = 0 (As you can see in the graphic)
2. If you evaluate x=π in the same function, then you have:
f(π) = 4sin(π− π/2)
f(π) = 4sin(π/2)
f(π) = 4 (As it is shown in the graphic)
N-10+9N-3. First combine like terms. -10 + -3 is -13. N + 9N = 10 N. Now all you need to do is divide. -13/10 equals: -1.3 You're welcome!

I'll show you a couple of examples, since all the exercises are to be done in the same way.
The point is that we can only sum two fractions if they have the same denominator. So, for example, we can sum
So, we first need to transform the two fractions so that they have the same denominators. A fraction can be transformed by multiplying both numerator and denominator by the same number. By doing so, you write another fraction with the same value as the original.
Let's deal with the first sum: we have 1/3 + 3/5. We transform the fraction as follows:
And now we can sum them:
