Answer:

Answer shown below.

Step-by-step explanation:

For 29;

It means f(x)= 9x + 2 =29

Therefore; 9x =29-2=27

9x = 27

X=27/9

x=3

Answer:

The answer is 3.

Step-by-step explanation:

In oder to find the value of x you have to let f(x) = 29 :

$f(x) = 9x + 2$

Let f(x) = 29

$9x + 2 = 29$

Next, you have to solve x by substracting 2 and divide 9 to both sides :

$9x + 2 = 29$

$9x + 2 - 2 = 29 - 2$

$9x = 27$

$9x \div 9 = 27 \div 9$

$x = 3$

How you make 8 21/40

Margaret [11]

Multiply the whole number by the denominator (8*40=320) then add it to the numerator (320+21=341).
Then you get 341/40

Show that the points (3,1) and (1,3) are the same distance from the origin

Phantasy [73]

Let's use the distance formula to find the distance between the origin and each of the points. We can use this to show that the distances are the same. Remember that the distance formula is:

$\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$(x_1, y_1)$ is one point
$(x_2, y_2)$ is the other point that you are trying the distance to

First, let's find the distance between the points (3, 1) and the origin, (0, 0). We will call this distance $D_1$ .

$D_1 = \sqrt{(3 - 0)^2 + (1 - 0)^2}$

$D_1 = \sqrt{3^2 + 1^2}$

$D_1 = \sqrt{10}$

Next, let's find the distance between (1, 3) and the origin, (0, 0). We will call this $D_2$ .

$D_2 = \sqrt{(1 - 0)^2 + (3 - 0)^2}$

$D_2 = \sqrt{1^2 + 3^2}$

$D_2 = \sqrt{10}$

We can see that $D_1 = D_2$ , or that the distances are the same. ✔︎

How to solve -5x+y =-2

denpristay [2]

First subtract y from both sides
(-5x=-2-y)

Add two to both sides
(-5x+2=-y)

Y cant be negative so divide by -1 to both sides
(5x-2=y)
