3.	5+6(m-1)=35Solve the equation
Answer» Answer: m=6 STEP-by-step explanation: Step 1: Simplify both sides of the equation. 5+6(m−1)=35 5+(6)(m)+(6)(−1)=35(Distribute) 5+6m+−6=35 (6m)+(5+−6)=35(Combine Like Terms) 6m+−1=35 6m−1=35 Step 2: ADD 1 to both sides. 6m−1+1=35+1 6m=36 Step 3: DIVIDE both sides by 6. 6m/6 =36/6 m=6

3.

5+6(m-1)=35Solve the equation

Answer»

Answer:

m=6

STEP-by-step explanation:

Step 1: Simplify both sides of the equation.

5+6(m−1)=35

5+(6)(m)+(6)(−1)=35(Distribute)

5+6m+−6=35

(6m)+(5+−6)=35(Combine Like Terms)

6m+−1=35

6m−1=35

Step 2: ADD 1 to both sides.

6m−1+1=35+1

6m=36

Step 3: DIVIDE both sides by 6.

6m/6

=36/6

m=6

4.

The product of number and 2 more than that is 168, what are the number

Answer»

Answer:

±12,14

Step-by-step EXPLANATION:

let NUMBERS be X,x+2

(x)(x+2)=168

x²+2x=168

x²+2x-168=0

x²+14x-12x-168=0

x(x+14)-12(x+14)=0

(x-12)(x+14)=0

therefore,x=12,-14

case1:x=12

x+2=14

case 2:x= -14

x+2=-12

6.	Anyone can give me a intro about heron's formula
Answer» ANSWER: In GEOMETRY, Heron's formula (SOMETIMES called Hero's formula), named after Hero of ALEXANDRIA, gives the AREA of a triangle when the length of all three sides are known. Unlike other triangle area formulae, there is no need to calculate angles or other distances in the triangle first Heron's formula states that the area of a triangle whose sides have lengths a, b, and c is {\displaystyle A={\sqrt {s(s-a)(s-b)(s-c)}},}A = \sqrt{s(s-a)(s-b)(s-c)}, where s is the semi-perimeter of the triangle; that is, {\displaystyle s={\frac {a+b+c}{2}}.}s=\frac{a+b+c}{2}.

1. Find the coordinates of the point equidistant from the points A(1, 2), B (3.-4) and C(5.-6).(a) (2,3)(d) (1,3)SIA

Answer»

GIVEN ,

The COORDINATES of the point equidistant from the POINTS A(1, 2) , B(3.-4) and C(5.-6)

Let , the coordinate of point P(x , y)

We know that , the distance between two points is given by

$\boxed{ \sf{Distance = \sqrt{ {( x_{2} - x_{1} )}^{2} + {(y_{2} - y_{1} )}^{2} } }}$

ACCORDING to the question ,

AB = BP

$\tt \sqrt{ {(x - 1)}^{2} + {(y - 2)}^{2} } = \sqrt{ {(x - 3)}^{2} + {(y + 4)}^{2}}$

$\tt {(x)}^{2} + 1 - 2x + {(y)}^{2} + 4 - 4y = {(x)}^{2} + 9 - 6y + {(y)}^{2} + 16 + 8y$

$\tt 5 - 2x - 4y = 25 - 6x + 8y$

$\tt 4x = 20 + 12y$

$\tt 4x - 12y = 20$

$\tt x - 3y = 5 - - - (i)$

And

BP = CP

$\tt \sqrt{ {(x - 3)}^{2} + {(y + 4)}^{2} } = \sqrt{ {(x - 5)}^{2} + {(y + 6)}^{2} }$

$\tt {(x)}^{2} + 9 - 6x + {(y)}^{2} + 16 + 8y = {(x)}^{2} + 25 - 10x + {(y)}^{2} + 36 + 12y$

$\tt 25 - 6x + 8y = 61 - 10x + 12y$

$\tt 4x - 4y = 36$

$\tt x - y = 9 - - - (ii)$

Subtract eq (i) from eq (ii) , we get

x - y - (x - 3y) = 9 - 5

3y - y = 4

2y = 4

y = 2

Put y = 2 in eq (ii) , we get

x - 2 = 9

x = 11

An item that a store originally sold for R6 950,82 was offered at a discount of 8,5%. The store still made a 20% profit on sale. The price that the store originally paid for the item is

Answer»

Given : An ITEM that a store ORIGINALLY sold for Rs 6 950.82 was offered at a DISCOUNT of 8,5%. The store still made a 20% profit on sale.

To Find : The price that the store originally paid for the item

Solution:

Let say store originally paid amount =Rs C

store made a 20% profit on sale = (20/100)C = Rs 0.2C

SELLING Price = C + 0.2C = Rs 1.2C

store originally sold for Rs 6950.82

Discount = 8.5 %

Discount = (8.5/100)6 950.82 = Rs 590.82

Selling Price = 6950.82 - 590.82 =Rs 6360

1.2C = 6360

=> C = 5300

39.

The sum of three consecutive odd numbers is 53 find the numbers

Answer»

Answer:

LET the three CONSECUTIVE number = x , x+2 , x+4

A.T.Q.

x+x+2+x+4 = 53

3x + 6 = 53

3x = 53-6

x = 47/3

x = 15.666(approx)

Therefore,

The three consecutive number are:

x = 15.666

x + 2 = 15.666+2 = 17.666

x + 4 = 15.666 +4 = 19.666

Determine whether points are collinear (-2,2) (0, 4) and (2,-10)

Answer»

Given ,

The three point are A(-2,2) , B(0, 4) and C(2,-10)

$\underline{ \sf{First \: method :}}$

We know that , if area of Δ ABC is zero , then three points A , B and C are COLLINEAR

$\boxed{ \sf{Area \: of \: triangle = \frac{1}{2} | x_{1}(y_{2} - y_{3}) + x_{2}(y_{3} - y_{1}) + x_{3}(y_{1} - y_{2})| }}$

Thus ,

$\sf \mapsto Area = \frac{1}{2} |2 \{ 4 - ( - 10)\} + 0 \{ - 10 - 2 \} + 2 \{ - 2 - 4 \}| \\ \\ \sf \mapsto Area = \frac{1}{2} |2 \{14 \} + 0 + 2 \{ 6\}| \\ \\ \sf \mapsto Area = \frac{1}{2} |28 - 12| \\ \\ \sf \mapsto Area = \frac{16}{2} \\ \\ \sf \mapsto Area =8 \: \: {units}^{2}$

Here , the area of Δ ABC ≠ 0

✭ The given three points are collinear

$\underline{ \sf{Second \: method :}}$

We know that ,

If three points A , B and C are collinear , then the slope of AB = slope of BC

$\boxed{ \sf{Slope \: (m) = \frac{ y_{2} - y_{1} }{x_{2} - x_{1} } }}$

Thus ,

Slope of AB = {4 - 2}/{0 - (-2)}

Slope of AB = 2/2

Slope of AB = 1

Similarly , the slope of BC will be

Slope of BC = {-10 - 4}/}2 - 0}

Slope of BC = -14/2

Slope of BC = -7

Here , Slope of AB ≠ Slope of BC

✭ The given three points are collinear
