Answer:
8 Yards because a yard is 3 feet
let's pick any two points off that table to get its slope.
![\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-7=-\cfrac{7}{2}[x-(-7)]\implies y-7=-\cfrac{7}{2}(x+7) \\\\\\ y-7=-\cfrac{7}{2}x-\cfrac{49}{2}\implies y=-\cfrac{7}{2}x-\cfrac{49}{2}+7](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7B%7Cc%7Cll%7D%20%5Ccline%7B1-1%7D%20%5Ctextit%7Bpoint-slope%20form%7D%5C%5C%20%5Ccline%7B1-1%7D%20%5C%5C%20y-y_1%3Dm%28x-x_1%29%20%5C%5C%5C%5C%20%5Ccline%7B1-1%7D%20%5Cend%7Barray%7D%5Cimplies%20y-7%3D-%5Ccfrac%7B7%7D%7B2%7D%5Bx-%28-7%29%5D%5Cimplies%20y-7%3D-%5Ccfrac%7B7%7D%7B2%7D%28x%2B7%29%20%5C%5C%5C%5C%5C%5C%20y-7%3D-%5Ccfrac%7B7%7D%7B2%7Dx-%5Ccfrac%7B49%7D%7B2%7D%5Cimplies%20y%3D-%5Ccfrac%7B7%7D%7B2%7Dx-%5Ccfrac%7B49%7D%7B2%7D%2B7)
Since Emily is walking at a constant speed, we can solve this using proportions, equating ratios of distance/time.
The first ratio is 3/4 miles/1/4 hour
The second ratio is 1 mile/ x hour
Equating the two ratios: 3/4 / 1/4 = 1/x
3 = 1/x
x = 1/3 hour
What language is that seriously
Answer:
Step-by-step explanation:
3x^2 + 7x + 9x^2 - 3x + 2
3x^2 + 9x^2 + 7x - 3x + 2
12x^2 + 7x - 3x + 2
Answer: 12x^2 + 4x + 2
This should be correct unless i'm dumb...
