Counting backwards next is 1
Answer:
The number of words, w, is the dependent variable.
Step-by-step explanation:
Answer:
y = 3x –5
Step-by-step explanation:
for slope-intercept form, y = mx + b
find the slope, m
(-8 -4)/(-1-3) = m
-12/-4 =m
3 = m
Substitute for m and use either coordinate for y and x to calculate b
4 = 3(3) + b
4 = 9 + b. Subtract 9 from both sides
4 –9 = b
–5 = b. Rewrite the equation with the calculated values for m and b
y = 3x –5
Check the picture below.
we know the area is 1586, so
![\stackrel{\textit{area of a trapezoid}}{A=\cfrac{h(a+b)}{2}}\implies 1586=\cfrac{26(84+b)}{2}\implies 1586=13(84+b) \\\\\\ \cfrac{1586}{13}=84+b\implies 122=84+b\implies 38=b](https://tex.z-dn.net/?f=%5Cstackrel%7B%5Ctextit%7Barea%20of%20a%20trapezoid%7D%7D%7BA%3D%5Ccfrac%7Bh%28a%2Bb%29%7D%7B2%7D%7D%5Cimplies%201586%3D%5Ccfrac%7B26%2884%2Bb%29%7D%7B2%7D%5Cimplies%201586%3D13%2884%2Bb%29%20%5C%5C%5C%5C%5C%5C%20%5Ccfrac%7B1586%7D%7B13%7D%3D84%2Bb%5Cimplies%20122%3D84%2Bb%5Cimplies%2038%3Db)
