Answer:

y = 4x - 1

Step-by-step explanation:

(1, 3) ; (2 ,7 )

Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{7-3}{2-1}\\\\=\frac{4}{1}\\\\= 4\\\\\\y - y_{1} = m(x -x_{1})\\\\y - 3 = 4(x - 1)\\\\y - 3 =4x - 4\\ y = 4x - 4 + 3\\y = 4x - 1

An online test of English spelling looked at how well people spelled difficult words. The bar graph to the right shows how many
sweet-ann [11.9K]

Answer:

60 ; 5220

Step-by-step explanation:

A) From the horizontal bar chart provided, it could be inferred that 85 people spell the word 'weird' correctly. The graph is scaled on a fixed interval of 10. Hence, the midpoint of 10 = 5

(80 + 5) = 85

B) In a group consisting of 8719 randomly selected people estimate how many more people can correctly spell weird than inoculate

From the graph :

85 per 100 could spell weird correctly while,

About 25 per 100 could spell inoculate correctly.

Difference In number per 100 people

(85 - 25) = 60 people per 100

We could round 8719 to the nearest 100 = 8700

Number of 100's in 8700 = 8700/100 = 87

(87 × 60) = 5,220 people

Convert to factored form <br> y = x² + 6x
steposvetlana [31]

<em><u>Convert to factored form is:</u></em>

y = x(x + 6)

<em><u>Solution:</u></em>

Given that,

y = x^2 + 6x

We have to convert to factored form

Factored form means writing terms in multiplication. i.e as a product

From given,

y = x^2 + 6x

Factor out x from above given expression

y = x(x + 6)

Here, the given equation is written as product of "x" and (x + 6)

Thus the factored form is found

Please help I'll give the brainiest to the right answer!
Anna [14]

Answer:

x=1

Step-by-step explanation:

Because vertical angles are always equal, we want to solve 50x+10=70x-10.

We can add 10 to both sides to get 50x+20=70x.

We can subtract 50x from both sides to get 20=20x.

Lastly, we divide both sides by 20 to get 1=x.

So, \boxed{x=1} and we're done!

The check is left as an exercise to the reader.

What is the volume of the square pyramid with bad edges 12cm and height 12cm?
spayn [35]
The volume of a pyramid is found by multiplying the length, width and height together then dividing by 3.

 length x width x height = 12 x 12 x 12 = 1728

volume = 1728 / 3 = 576 cubic cm
