Answer:
m equals 3x+21 because you add 2x+1x=3x.then you add 14+7=21.then you combine them together to get 3x+21
Step-by-step explanation:
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>

Expression 3,
because 6 and 8 are factors of 48. Since positive 6 & 8 are the two numbers of choice, the product will be positive. My answer is reasonable because if you were to multiply positive 8 and 6 you will get positive 48.
Answer:
-1/20

Answer:
![y=20\degree](https://tex.z-dn.net/?f=y%3D20%5Cdegree)
Step-by-step explanation:
The given triangle is isosceles. Therefore the base angles are equal.
This implies that,
.
To find
we add the interior add angles and equate to
.
This implies,
![(3y+70)\degree +25\degree +5x\degree =180\degree](https://tex.z-dn.net/?f=%283y%2B70%29%5Cdegree%20%2B25%5Cdegree%20%2B5x%5Cdegree%20%3D180%5Cdegree)
We substitute to obtain,
![\Rightarrow (3y+70)\degree +25\degree +25\degree =180\degree](https://tex.z-dn.net/?f=%5CRightarrow%20%283y%2B70%29%5Cdegree%20%2B25%5Cdegree%20%2B25%5Cdegree%20%3D180%5Cdegree)
We evaluate to obtain,
![\Rightarrow 3y+120\degree =180\degree](https://tex.z-dn.net/?f=%5CRightarrow%203y%2B120%5Cdegree%20%3D180%5Cdegree)
![\Rightarrow 3y=180\degree-120\degree](https://tex.z-dn.net/?f=%5CRightarrow%203y%3D180%5Cdegree-120%5Cdegree%20)
![\Rightarrow 3y=60\degree](https://tex.z-dn.net/?f=%5CRightarrow%203y%3D60%5Cdegree)
We divide through by 3 to get.
![\Rightarrow y=20\degree](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D20%5Cdegree)
