Answer:
r = -7
Step-by-step explanation:
-4 + 2r - 5r = 17
=> 2r - 5r = 17 + 4
=> -3r = 21
=> r = 21/(-3)
=> r = -7
Answer:
![m =5](https://tex.z-dn.net/?f=m%20%3D5)
Step-by-step explanation:
================================================
The "<em>constant rate of change</em>" is also known as the slope (in straight line equations).
The equation is in <em>slope-intercept form</em>.
================================================
<em>Slope-Intercept Form is: </em>
<em></em>![y = mx + b\\ \rule{150}{0.5}\\ \text{m - slope}\\ \text{b - Y-Intercept}](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b%5C%5C%0A%5Crule%7B150%7D%7B0.5%7D%5C%5C%0A%5Ctext%7Bm%20-%20slope%7D%5C%5C%0A%5Ctext%7Bb%20-%20Y-Intercept%7D)
================================================
<em>Since '5' takes up 'm's spot, it is the slope, or the constant rate of change. </em>
================================================

Given a right triangle with base, b and height, h with the angle opposide side h as θ.
The area of a triangle is given by
![A= \frac{1}{2} bh](https://tex.z-dn.net/?f=A%3D%20%5Cfrac%7B1%7D%7B2%7D%20bh)
But,
![\tan\theta= \frac{h}{b} \\ \\ \Rightarrow h=b\tan\theta](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%20%5Cfrac%7Bh%7D%7Bb%7D%20%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20h%3Db%5Ctan%5Ctheta)
Therefore, the area of the triangle in terms of <span>b and θ only is given by
</span>
A: -15/5 degrees Celsius
B: -15/5=3 degree Celsius
every 5 weeks it change -15°c
so each week it changes -3°c
There's not enough information to find out how long segment CB is or any other segment for that matter.
Sorry I couldn't be of much help.
