Do you add or subtract?

Hi there!

You would add for this problem.

If you're wondering why, the answer is very simple. You just have to look for key words. I saw the word "grow".
If grow means to increase, and so does "add", then you will need to add.

Hope this helps! :)

Here's a graph of a linear function. write the equation that describes that function.
7nadin3 [17]

Answer:

Step-by-step explanation:

slope intercept form  =>   Y = mx + b  

find m... the slope by using any two points on the line

p1 = (0,5)  by inspection

p2=(4,6)  by inspection

find m  = y2-y1 / x2-x1

      m   = 6 - 5 / 4 - 0  

      m    =1 / 4

then use the slope intercept formula

y = 1/4x + 5      for your answer.  we know b = 5 b/c thats where the line crosses the y axis.

y = \frac{1}{4}x + 5    is the answer

Simple and easy question<br> please help
In-s [12.5K]

Answer:

Total volume of the figure = 1067 cm³

Step-by-step explanation:

Volume of the composite figure = Volume of the rectangular prism + Volume of the square pyramid

Volume of the rectangular prism = Length × Width × Height

                                                      = 10 × 10 × 7

                                                       = 700 cm³

Volume of the square pyramid = \frac{1}{3}(\text{Area of the base})\times (\text{height})

                                                   = \frac{1}{3}(\text{Side})^2 × height

                                                   = \frac{1}{3}(10)^2(18-7)

                                                   = 366.67 cm³

Total volume of the composite figure = 700 + 366.67 = 1066.67 cm³

                                                                                          ≈ 1067 cm³
