Answer:

Step-by-step explanation:

Hi,

To begin, we have one mixed number and one fraction. In order to solve, we have to turn the mixed number into an improper fraction.

2 3/4 as an improper fraction is 11/4. We know this because we multiply the denominator by the whole number which is 4 x 2 = 8 and then add the result to the numerator which is 8 + 3 = 11. The denominator stays the same.

So...

11/4 - (-1/4)

- (-) always turns into a +. So when subtracting a negative, take those two subtraction signs, cancel them out, and add instead.

11/4 + 1/4 = 12/4

We can add straight across since they have the same denominator.

12/4 = 3

I hope this helps :)

I really need help with this math problem and please explain (-1) + (-2 2/5) =

ratelena [41]

Answer: -3 2/5

Step-by-step explanation:

When both integers are negative, you can treat them the same as positive numbers and add a negative sign to your final sum.

1+2 2/5 (or 2 4/10 or 2.4) is equal to 3 2/5. So (-1)+ (-2 2/5) is equal to -3 2/5, or -3.4.

Answer:

see below

Step-by-step explanation:

(a) the graph is symmetrical about the horizontal axis. It has a maximum value of r = 3 at θ = π.

(b) The graph is symmetrical about both the horizontal and the vertical axis. It has a maximum value of r = 1 at θ = 0 and θ = π. (Note this curve has subtle differences from the inner loop of the above curve.)

<em>About how</em>

As with any graphing problem, when doing it by hand, one chooses enough points to give the general shape of the curve. In some cases, quite a few points may be required. It is often helpful to use a spreadsheet for calculating the point values. Here, we've graphed the equations using "technology"--a graphing calculator.
