those are the only ones with two terms being added
Hey there! :)
Answer:
16 minutes.
Step-by-step explanation:
Create an equation in the form y = mx + b to solve this problem. Begin by solving for the rate of change of the table using the slope formula:
![m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B%5Ctext%7Brise%7D%7D%7B%5Ctext%7Brun%7D%7D%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
Plug in values from the table into the equation:
![m = \frac{64 - 40}{9 - 5}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B64%20-%2040%7D%7B9%20-%205%7D)
Simplify:
![m = \frac{24}{4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B24%7D%7B4%7D)
m = 6.
Plug in the slope and a point from the table into the equation
y = mx + b
40 = 6(5) + b
40 = 30 + b
40 - 30 = b
b = 10.
Rewrite the equation:
y = 6x + 10
To solve for how long it took her to ride 1 km, plug 1 into the equation:
y = 6(1) + 10
y = 6 + 10
y = 16 minutes.
It’s hard to completely answer without a graph or coordinates, but I do believe that point slope form is y-y1=m(x-x1). Plug in your slope for m. After that, plug in your x coordinate in the appropriate place as well as your y coordinate. Solve from there
Well c is the same exact problem but D could be it to because it easier to solve for x
Answer:
![3672 cm^3](https://tex.z-dn.net/?f=3672%20cm%5E3)
Step-by-step explanation:
There is a typo in the question, the lengths of the sides of the prism are:
24 cm
9 cm
17 cm
(otherwise, if all sides were 9 cm, it would be a cube, not a prism)
The volume of a rectangular prism is given by:
![V=l\cdot w\cdot h](https://tex.z-dn.net/?f=V%3Dl%5Ccdot%20w%5Ccdot%20h)
where:
l is the length of the prism
w is the width of the prism
h is the height prism
In this problem,
(length)
(width)
(height)
Therefore, the volume of the prism is:
![V=24\cdot 9 \cdot 17 = 3672 cm^3](https://tex.z-dn.net/?f=V%3D24%5Ccdot%209%20%5Ccdot%2017%20%3D%203672%20cm%5E3)
