answer:
C. 16
explanation:
when x is 0, the y-intercept is 8
coordinates: (0,8) and (4,6)
slope:
![\sf \frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Csf%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
![\sf \frac{6-8}{4-0}](https://tex.z-dn.net/?f=%5Csf%20%5Cfrac%7B6-8%7D%7B4-0%7D)
![\sf \frac{-2}{4}](https://tex.z-dn.net/?f=%5Csf%20%5Cfrac%7B-2%7D%7B4%7D)
![\sf -\frac{1}{2}](https://tex.z-dn.net/?f=%5Csf%20-%5Cfrac%7B1%7D%7B2%7D)
equation:
[ where m is slope and b is y-intercept ]
![y = \sf -\frac{1}{2}x +8](https://tex.z-dn.net/?f=y%20%3D%20%5Csf%20-%5Cfrac%7B1%7D%7B2%7Dx%20%2B8)
solve for x-intercept:
note: zeros of a function are the values of x when f(x) is equal to 0
![y = \sf -\frac{1}{2}x +8](https://tex.z-dn.net/?f=y%20%3D%20%5Csf%20-%5Cfrac%7B1%7D%7B2%7Dx%20%2B8)
![0= \sf -\frac{1}{2}x +8](https://tex.z-dn.net/?f=0%3D%20%5Csf%20-%5Cfrac%7B1%7D%7B2%7Dx%20%2B8)
![-8= \sf -\frac{1}{2}x](https://tex.z-dn.net/?f=-8%3D%20%5Csf%20-%5Cfrac%7B1%7D%7B2%7Dx)
![\sf x = -8 * -2](https://tex.z-dn.net/?f=%5Csf%20x%20%3D%20-8%20%2A%20-2)
![\sf x = 16](https://tex.z-dn.net/?f=%5Csf%20x%20%3D%2016)
Answer:
76
Step-by-step explanation:
A full triangle is 180 *always remember
180-153=27
so r is 27
180-77-27=76
or you could do
77+27+x=180
104+x=180
x=180-104
x=76
Answer:
The answer is 15
Step-by-step explanation:
15*3=45-5=40
Answer:
![\boxed{\sf \ \ \ m = -\dfrac{tn}{t-s} \ \ \ }](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%20%5C%20%5C%20%5C%20m%20%3D%20-%5Cdfrac%7Btn%7D%7Bt-s%7D%20%5C%20%5C%20%5C%20%7D)
Step-by-step explanation:
Hello,
let s assume that m+n is different from 0
we have this equation and we need to find m as a function of t, s, and n
![t=\dfrac{ms}{m+n}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7Bms%7D%7Bm%2Bn%7D)
<=>
![(m+n)*t=ms\\\\ tm+tn=sm\\ (t-s)m = -tn\\ m = -\dfrac{tn}{t-s}](https://tex.z-dn.net/?f=%28m%2Bn%29%2At%3Dms%5C%5C%5C%5C%3C%3D%3E%20tm%2Btn%3Dsm%5C%5C%3C%3D%3E%20%28t-s%29m%20%3D%20-tn%5C%5C%3C%3D%3E%20m%20%3D%20-%5Cdfrac%7Btn%7D%7Bt-s%7D)
for t-s different from 0, so t different from s
hope this helps
