Answer:
3
Step-by-step explanation:
(x₁ , y₁) = (-1 , -2) & (x₂ , y₂) = (3 , 10)
![= \frac{10-[-2]}{3-[-1]}\\\\=\frac{10+2}{3+1}\\\\=\frac{12}{4}\\\\=4](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B10-%5B-2%5D%7D%7B3-%5B-1%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B10%2B2%7D%7B3%2B1%7D%5C%5C%5C%5C%3D%5Cfrac%7B12%7D%7B4%7D%5C%5C%5C%5C%3D4)
m = 4
y - y₁ = m (x - x₁)
y - [-2] = 4(x - [-1])
y + 2 = 4(x + 1)
y + 2 = 4x + 4
y = 4x + 4 - 2
y = 4x + 2
3 probably. If 2 plates break out of 150 then you know that dividing 150 with 2 you get 75 and that means that 75 = 1 broken plates and which means that the next weak will be 1 broken plate. 150+75=225.
Answer:
L = 11 m
Step-by-step explanation:
The perimeter is 40 m, which in turn equals 2L + 2W. With W = 9 m, we have:
40m = 2L + 2(9 m), or 40 m = 2L + 18 m, or 22 m = 2L. Then L = 11 m.
1.50-0.90=0.60
0.60/1.50=x/100
cross multiply (0.60*100=1.50x)
60/1.50=40
