Which point is a solution to the system below 2y<-12x+4 y<-6x+4?

Lera25 [3.4K]

Answer: All points in the shaded region after 2y<-12x+4 is the solution.

Step-by-step explanation:

Since we have given that

$2y$

We need to find the point of solution to the system of inequalities:

Suppose

$2y=-12x+4\\and\\y=-6x+4$

We first check the consistency of the system of equation:

$\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}\\\\\frac{2}{1}=\frac{-12}{-6}=\frac{4}{4}\\\\2=2\neq 1$

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,

$2y$

0<4 it is true so, shaded part is towards the center.

Similarly,

$y$

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.

What is the equation x = y + z solved for z?

Mars2501 [29]

To solve the problem for z you would need to undo the equation x=y+z to do so you would subtract y from both sides resulting in x-y=z

The vertices of ΔGHI are G (2, 4), H (4, 8), and I (8, 4). The vertices of ΔJKL are J (1, 1), K (2, 3), and L (4, 1). Which conc

Klio2033 [76]

Answer:

They are similar by the definition of similarity in terms of a dilation.

Step-by-step explanation:

The first step is finding the sides of each triangle.

In triangle GHI, we have that:

GH = sqrt((4-2)^2 + (8-4)^2) = 4.4721

HI = sqrt((8-4)^2 + (4-8)^2) = 5.6569

IG = sqrt((2-8)^2 + (4-4)^2) = 6

Now, for the triangle JKL, we have:

JK = sqrt((2-1)^2 + (3-1)^2) = 2.2361

KL = sqrt((4-2)^2 + (1-3)^2) = 2.8284

LJ = sqrt((1-4)^2 + (1-1)^2) = 3

The triangles are not congruent, because the sides are different

They are similar, because their sides have a proportion (sides of GHI are 2 times the sides of JKL). If they are similar, they have the same angles.

The ratio of their corresponding sides is 1:2, not 1:3

The ratio of their corresponding angles is 1:1, not 1:3
