Mathematics
1 answer:
Rasek [7]3 years ago
7 0

Answer:

Hello. Let me explain.

Step-by-step explanation:

For the first question.

m =  \frac{y2 - y1}{x2 - x1 }  =  \frac{8 - ( - 6)}{ - 3 - 4}  =  \frac{14}{ - 7}  =  - 2

For the second question.

y - y0 = m(x - x0) \\ y + 6 =  - 2(x - 4) \\ y =  - 2x + 8 - 6 \\ y =  - 2x + 2

So b is +2

Hope you understand

Write 75% as a decimal and fraction in simplest form.<br> SHOW ALL WORK.
Andrews [41]
75% means 75 per cent, or per hundred.
"Per cent" means "per hundred" or "0.01".
This means that 75% is 0.75 in decimal form.
75% as a fraction means 75 per hundred.
Keep in mind that "per" means to divide.
So, let's translate this into parenthesis.
75 (75) per (/) hundred (100).
Rewrite with only the parenthesis.
75 / 100.
This is 75% in fraction form, but isn't simplified. We can divide both numbers by 25.
75 / 25 = 3
100 / 25 = 4
Your simplified fraction is 3/4.

I hope this helps!

The diagram shows a rhombus inside a regular hexagon work out the angle x
kvv77 [185]

Answer:

<u>x = 60°</u>

Step-by-step explanation:

The rest of the question is the attached figure.

And it is required to find the angle x.

As shown, a rhombus inside a regular hexagon.

The regular hexagon have 6 congruent angles, and the sum of the interior angles is 720°

So, the measure of one angle of the regular hexagon = 720/6 = 120°

The rhombus have 2 obtuse angles and 2 acute angles.

one of the obtuse angles of the rhombus is the same angle of the regular hexagon.

So, the measure of each acute angle of the rhombus = 180 - 120 = 60°

So, the measure of each acute angle of the rhombus + the measure of angle x = the measure of one angle of the regular hexagon.

So,

60 + x = 120

x = 120 - 60 = 60°

<u>So, the measure of the angle x = 60°</u>

How can you be sure that 0.1 ÷ 100 = 0.001?
KATRIN_1 [288]

Answer: When dividing by 100, move the decimal two places to the left

Step-by-step explanation: 0.1 / 100 = 0.001

There are 2 zeros in 100 so you move the decimal to the left 2 times when you are dividing. When you move the decimal 2 times in 0.1 you get 0.001
