B. 6. To get the probability of 6, divide 50 by 6. That’s is 8.3, which is close to 8. Please mark brainliest would greatly be appreciated.

Solve the system of equation

nikdorinn [45]

Answer:

So the Point of intersection is (-4,-2)

Which is option A

Step-by-step explanation:

The given system of equations is

-0.1x - 0.8y = 2 ...................(i)

0.6x - 0.5y = -1.4 ...................(ii)

Let us take equation (i) and use method of substitution for solving it

the equation (i) is

-0.1 x - 0.8y = 2

Adding 0.8y on both sides

-0.1 x + 0.8 y - 0.8 y = 2 + 0.8 y

-0.1 x = 2 + 0.8 y

Dividing both sides -0.1

$\frac{-0.1 x}{-0.1}=\frac{0.8 y}{-0.1}+\frac{2}{-0.1}$

x = -8 y - 20 ..........................(iii)

Now we will use this value and put it into equation (ii) to find the value of y

Equation (ii) is

0.6 x - 0.5 y = -1.4

Put value of x

0.6(-8 y - 20) - 0.5 y =-1.4

It becomes

-4.8 y - 12 - 0.5 y = -1.4

adding 12 on both sides

-4.8 y - 0.5 y - 12 + 12 = -1.4 + 12

it becomes by solving

-5.3 y = 10.6

Dividing both sides by -5.3

$\frac{-5.3*y}{-5.3}=\frac{10.6}{-5.3}$

y = -2

Now we have the value of y putting it in equation (iii)

Equation (iii) is

x = -8 y - 20

Putting value of y

x = -8*(-2) - 20

x = 16-20

x=-4

So the Point of intersection is (-4,-2)

If the domain of the coordinate transformation f(x,y)=(y+2,-x-4) is (1,-4),(3,-2), (0,-1)

Mama L [17]

Answer:

The Fundamental Graphing Principle for Functions says that for a point (a, b) to be on the graph,

f(a) = b. In particular, we know f(0) = 1, f(2) = 3, f(4) = 3 and f(5) = 5. Suppose we wanted to

graph the function defined by the formula g(x) = f(x) + 2. Let’s take a minute to remind ourselves

of what g is doing. We start with an input x to the function f and we obtain the output f(x).

The function g takes the output f(x) and adds 2 to it. In order to graph g, we need to graph the

points (x, g(x)). How are we to find the values for g(x) without a formula for f(x)? The answer is

that we don’t need a formula for f(x), we just need the values of f(x). The values of f(x) are the

y values on the graph of y = f(x). For example, using the points indicated on the graph of f, we

can make the following table.

x (x, f(x)) f(x) g(x) = f(x)

In general, if (a, b) is on the graph of y = f(x), then f(a) = b, so g(a) = f(a) + 2 = b + 2. Hence,

(a, b+ 2) is on the graph o

main role x (x, f(x)) f(x) g(x) = f(x) + 2 (x, g(x))

0 (0, 1) 1 3 (0, 3)
