The slope is 1/8

Step-by-step explanation:

Answer:

[tex]\frac{1}{8}[/tex]

Step-by-step explanation:

The formula for finding the slope of a line is;

[tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1}}[/tex]

Any two coordinate pairs ( (x,y) ) on the given table can be used, for this problem, let us use the first two given pairs.

( -8 , 2 )

( 0 , 3 )

[tex]x_{1} = -8\\y_{1} = 2\\x_{2}= 0\\y_{2} = 3[/tex]

Substitute into the formula and solve;

[tex]\frac{3 - 2 }{0 - (-8)}[/tex]

= [tex]\frac{1}{8}[/tex]

A rectangle is x inches wide and 3y inches long. If the length plus twice the width is 12 inches and the length plus the width is 9 inches, what is the length

Answers

Answer:

6

Step-by-step explanation:

12-2(3)=6

9-(3)=6

The length of the rectangle is 6 inches.

What is the system of equations?

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

A rectangle is x inches wide and 3y inches long.

If the length plus twice the width is 12 inches and the length plus the width is 9 inches.

That means,

2x + 3y = 12    {equation 1}

x + 3y = 9      {equation 2}.

To solve the system of equations:

Subtract the equation 2 to equation 1.

x = 3

And y = 2.

Therefore, the length is 6 inches.

How do i measure the diameter of a circle?

Answers

Answer:

Step-by-step explanation:

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter

hope that helps!

The steps to measure the diameter of a circle is shown below.

You must perform the following steps in order to determine a circle's diameter:

1. Lay a ruler or measuring tape over the circle's centre, making sure it goes through the widest point.

2. Check to make sure the ruler or measuring tape is straight and correctly positioned.

3. Check the measurement at the intersection of the circle's two sides using the ruler or measuring tape.

4. Make a note of the measurement you took.

5. To find the circle's diameter, multiply the measurement you took by two.

The piece of a straight line that connects two places on the circumference and travels through the centre of a circle is known as the diameter.
