Step-by-step explanation:

Given values in table :

x        f(x)

3         -1

4          0

5          1

6          2

Here we see there is a difference of 4 in the values of x and f(x)

i.e. 3-(-1)=4

or 4-0=4

Similarly 5-1=4

6-2=4

So x-F(x)=4

Adding F(x) -4 both sides

x-F(x) +F(x) -4=4+F(x) -4

We have F(x)= x-4

2x+y+2z=7, 2x-y+2z=1, 5x+y+5z=13

Answers

Answer:

y = 3

x = 2 - z

Step-by-step explanation:

We have the system:

2*x+y+2*z=7

2*x-y+2*z=1

5*x+y+5*z=13

In the first and second equations we have the term (2*x + 2*z) = A

Then we can rewrite the first two equations as:

A + y = 7

A - y = 1

isolating A in the first equation, we get:

A = 1 + y

Now we replace this in the other equation:

(1 + y) + y = 7

1 + 2*y = 7

2*y = 6

y = 3.

then:

A + y = 7

A + 3 = 7

A = 7- 3 = 4

A = 2*x + 2*z  = 4.

Now let's go to the third equation:

(5*x + 5*z) + y = 13

we can rewrite the thing inside the parentheses as:

(5/2)*(2*x + 2*y) + y = 13

And we know that:

2*x + 2*z = 4

y = 3

then this can be written as:

(5/2)*(4) + 3 = 5*2 + 3 = 13

Then we can conclude that:

y = 3

2*z + 2*x = 4

2*(z + x) = 4

(z + x) = 4/2 = 2

x = 2 - z

Notice that the solution is not only a point, we have infinite solutions for this problem.

Find the coordinates of P so that P partitions segment A to B in the ratio 5:1 with A(2,
4) and B(8, 10).

Answers

Answer:

Point P has coordinates (7,9) (last choice)

Step-by-step explanation:

We are given the endpoints A(2,4) B(8,10) and the point P lying on the segment AB with the condition that P partitions it in the ratio 5:1.

This means the distances AP, PB and AB follow the conditions:

[tex]\frac{AP}{PB}=\frac{5}{1}[/tex]

AP+PB=AB

We can work with each coordinate separately. Suppose P has coordinates (x,y), thus:

[tex]x-x_a=5(x_b-x)[/tex]

[tex]x-x_a=5x_b-5x[/tex]

Adding 5x and subtracting:

[tex]6x=5x_b+x_a[/tex]

Dividing by 6:

[tex]\displaystyle x=\frac{5x_b+x_a}{6}[/tex]

Substituting:

[tex]\displaystyle x=\frac{5*8+2}{6}=\frac{42}{6}=7[/tex]

x=7

Now for the y-axis:

[tex]\displaystyle y=\frac{5y_b+y_a}{6}[/tex]

Substituting:

[tex]\displaystyle y=\frac{5*10+4}{6}=\frac{54}{6}=9[/tex]

y=9

Point P has coordinates (7,9) (last choice)
