Step-by-step explanation:

slope of MN=(-1-5)/(7-1)=-6/6=-1

slope of line ⊥ to given line=-1/(-1)=1

To find mid point of M and N

[tex]x=\frac{1+7}{2} =4\\y=\frac{5+(-1)}{2} =2[/tex]

eq. of perpendicular bisector is

y-2=1(x-4)

y=x-4+2

or y=x-2

Answer:

No

Step-by-step explanation:

You use the Pythagorean Therom and square your legs (5 and 12) and your hypotenuse (14) it would add up to 25+144=196.

This is not true since 144+25 is 169, not 196

Answer:

No, it is not a right triangle.

Step-by-step explanation:

You can determine whether a triangle is a right triangle by using the pythagorean theorem.

a^2 + b^2 = c^2

c will always be the longest side of the triangle, so in this case you need to substitute 5 and 12 in for a and b and see if it simplifies to 15.

5^2 + 12^2 = c^2

25 + 144 = c^2

c^2 = 169

c = 13

C would be 13, not 15, so the triangle is not a right triangle

[tex]\boxed{\textsf{ The correct option is Option B \textbf{Chemical Change}.}}[/tex]

Step-by-step explanation:

Alkali metals such as Pottasium must be transported in special sealed containers because they have the ability to born or exclude upon contact with water due to their high reactivity. This is an example of Chemical Change .

Alkali metals like Pottasium (K) , Sodium (Na) , etc react vigorously with water . So they should be prevented in coming in contact to water . They are generally stored in kerosene . Here's an example of reaction of Alkali Metals with water .

Answer:

3 minutes

Step-by-step explanation:

To calculate this, you have to multiply 4.5 minutes by 8. This will give you the amount of pages that Wafa will print.

4.5 x 8 = 36 pages

Now that you have the amount of pages, you should divide it by the speed of the Sure-Fire printer. 12 ppm means that 12 pages can be printed in 1 minute.

36/12 = 3

Therefore, it would take 3 minutes if Wafa were to use her brother's Sure-Fire printer.

Answer:

3 minutes

Step-by-step explanation:

Apricot prints 8 pages per minute, the Sure-fire prints 12.

That means Wafa's brother's printer is 1.5 times faster than Wafa's own.

That means his printer can print the document in 4.5min / 1.5 = 3min

The temperature outside is -12 degrees Fahrenheit.

Zero is where the temperature changes from a negative value to a positive value.

Answer:

40008 07 is the answer good luck :)

Answer:

positive

Step-by-step explanation:

the reasoning behind this is because when you do powers you multiply the number by itself. If you multiply -2x-2 then it turns into a positive number and will stay a positve number

Equivalent of those that bought chips

From the question, 3 out of the 4 girls bought chips.

So, the fraction is:

[tex]Chips = \frac{3}{4}[/tex]

Express as decimal

[tex]Chips = 0.75[/tex]

Hence: the decimal equivalent is 0.75

hope it helps you

The expression (3x + 1)(x + 4)(2x + 7) in the form ax3³ + bx² + cx + d

is  6x³ + 29x² + 36x + 28.

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, A product of three linear binomials which will result to a cubic polynomial.

Therefore,

(3x + 1)(x + 4)(2x + 7),

= (3x² + 3x + x + 4)(2x + 7).

= (3x² + 4x + 4)(2x + 7).

= 6x³ + 21x² + 8x² + 28x + 8x + 28.

= 6x³ + 29x² + 36x + 28.
