A- x/2 + 3/4................
B- 6 + n............
Answer:
it's false
the true is -1/2
Step-by-step explanation:
-5/2-2+4=-1/2
Answer: All points in the shaded region after 2y<-12x+4 is the solution.
Step-by-step explanation:
Since we have given that
![2y](https://tex.z-dn.net/?f=2y%3C-12x%2B4%20%5C%5C%5C%5Cand%5C%5C%5C%5Cy%3C-6x%2B4)
We need to find the point of solution to the system of inequalities:
Suppose
![2y=-12x+4\\and\\y=-6x+4](https://tex.z-dn.net/?f=2y%3D-12x%2B4%5C%5Cand%5C%5Cy%3D-6x%2B4)
We first check the consistency of the system of equation:
![\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}\\\\\frac{2}{1}=\frac{-12}{-6}=\frac{4}{4}\\\\2=2\neq 1](https://tex.z-dn.net/?f=%5Cfrac%7Ba_1%7D%7Ba_2%7D%3D%5Cfrac%7Bb_1%7D%7Bb_2%7D%3D%5Cfrac%7Bc_1%7D%7Bc_2%7D%5C%5C%5C%5C%5Cfrac%7B2%7D%7B1%7D%3D%5Cfrac%7B-12%7D%7B-6%7D%3D%5Cfrac%7B4%7D%7B4%7D%5C%5C%5C%5C2%3D2%5Cneq%201)
So, it is parallel system of equations, but we consider it as an inequality, so all the points in the shaded region is the solution.
Using zero test,
![2y](https://tex.z-dn.net/?f=2y%3C-12x%2B4)
0<4 it is true so, shaded part is towards the center.
Similarly,
![y](https://tex.z-dn.net/?f=y%3C-6x%2B4)
0<4 again it is true it would be shaded towards the center.
So, the common part will be after 2y<-12x+4 .
Hence, all the points in the shaded region is the solution.
Answer:
480 m²
Step-by-step explanation:
A = bh/2
A = 64 m × 15 m / 2
A = 480 m²
Answer:
x >= 74
Step-by-step explanation:
x/10 (* 10) + 6 >= 8 (* 10)
x + 6 (- 6) >= 80 (- 6)
x >= 74
