Answer:

y =-2x+7

Step-by-step explanation:

Hello : let  A(2,3)    B(1,5)

the slope is :   (YB - YA)/(XB -XA)

(5-3)/(1-2)  = 2/-1 =-2

an equation is : y=ax+b     a is a slope

y = -2x +b

the line through point  (2,3) :  3 = (-2)(2)+b    

b = 7

the equation is : y =-2x+7

Step-by-step explanation:

Answer:

x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 = 9x+18

so there are 9 twos or 18 and 9x. No value is provided for x so the answer is 18+9x.

f(x) = x^2 - 5x + 5

Let x=3

f(3) = 3^2 -5(3) +5

      = 9 -15+5

      = -6+5

      =-1

Answer:

900

Step-by-step explanation:

The area of the final triangle would be 900 cm².

Scale factor is used to compare the final and initial dimensions of the figure. Mathematically, we can write scale factor -

{K} = {final dimensions/initial dimensions}

Given is that a triangle has an area of 36 cm². The base and height are scaled by a factor of 5.

Assume the initial dimensions of the triangle be {x} and {y} respectively. So, we can write the initial area as -

{1/2}{x}{y} = 36

{x}{y} = 72

After the scaling, we can write the final area as -

A = {1/2}{5x}{5y}

A = {25/2}{x}{y}

A = 12.5 x 72

A = 900 cm²

Therefore, the area of the final triangle would be 900 cm².

Step-by-step explanation:

Answer:

Perimeter is equal to all four sides added together.

Length = 3W; L=3W

So

P = 2(W) + 2(L)  substitute the equation for length above you get

P = 2(W) + 2(3W)  and combine

P = 2W + 6W = 8W; put in what the perimeter is and solve for W

66 = 8W, so W = 8.25

W = 8.25, L = 24.75

3/16 of her garden are red roses

she was not correct, 2/4 is not equal to 3/16

Step-by-step explanation:

3/4 garden are roses

1/4 of those are red  (1/4 of 3/4)

3/4 (1/4) = 3/16 of her garden are red roses

Answer:

Yes she is correct because if you have the 3/4 u still have 1/4 un planted an then she adds the 1/4 an that would make it 2/4.

Answer:

The perimeter of the garden, in meters, is [tex]24\sqrt{2}[/tex]

Step-by-step explanation:

Diagonal of a square:

The diagonal of a square is found applying the Pythagorean Theorem.

The diagonal of the square is the hypothenuse, while we have two sides.

Diagonal of 12m:

This means that [tex]d = 12[/tex], side s. So

[tex]s^2 + s^2 = 12^2[/tex]

[tex]2s^2 = 144[/tex]

[tex]s^2 = \frac{144}{2}[/tex]

[tex]s^2 = 72[/tex]

[tex]s = \sqrt{72}[/tex]

Factoring 72:

Factoring 72 into prime factors, we have that:

72|2

36|2

18|2

9|3

3|3

1

So

[tex]72 = 2^{3}*3^{2}[/tex]

So, in simplest radical form:

[tex]s = \sqrt{72} = \sqrt{2^{3}*3^{2}} = \sqrt{2^3}*\sqrt{3^2} = 2\sqrt{2}*3 = 6\sqrt{2}[/tex]

Perimeter of the garden:

The perimeter of a square with side of s units is given by:

[tex]P = 4s[/tex]

In this question, since [tex]s = 6\sqrt{2}[/tex]

[tex]P = 4s = 4*6\sqrt{2} = 24\sqrt{2}[/tex]

The perimeter of the garden, in meters, is [tex]24\sqrt{2}[/tex]

Answer:

2) x = -3

Step-by-step explanation:

Collect like terms, so gather all your x's on one side, and numbers in the other.  Add -6x and +15 to both sides, so you get -2x - 6x = +9 + 15, so we have -8x = 24, divide both sides by -8 you get x = -3.

Let x represents an even integer. Another positive consecutive even integer will be (x+2).

According to question,

The difference of the squares of two positive consecutive even integers is 52 i.e.

[tex](x+2)^2-x^2=52\\\\x^2+4+4x-x^2=52\\\\4+4x=52\\\\4x=52-4\\\\4x=48\\\\x=12[/tex]

Answer:

x ≤ 10.3 people

Approximately x ≤ 10 people

Step-by-step explanation:

Parking = $17.50

Tickets = $25 per person

Let

x = number of people who can go to the amusement park.

17.50 + 25x ≤ 275

25x ≤ 275 - 17.50

25x ≤ 257.50

x ≤ 257.50/25

x ≤ 10.3

Approximately 10 people can to the amusement park

Answer:

177

Step-by-step explanation:

If the top 5 performers are not considered, the average drops by 2.

Thus,average without top 5 performers = 85 - 2 = 83

Total scored with 5 table toppers = 52 × 85 = 4420

Total scored without 5 table toppers = 47 × 83 = 3901

Total scores of top 5 table toppers = 4420 - 3901 = 519

We are told that each of the 5 top scorers had distinct integral scores.

Also, all of them will score greater than 83.

Thus,possible maximum score of table topper = 519 - (84 + 85 + 86 + 87) = 177

Answer:

Step-by-step explanation:

x-5(x-1) = x- (2x-3)​

x  + x *(-5) + (-1) * (-5) = x +  2x*(-1) + (-3)*(-1) {use distributive property}

x - 5x + 5 = x - 2x +3   {Combine like terms}

    -4x + 5 = - x +3           {Add 'x' to both sides}

-4x + 5 + x  = -x + x + 3

       -3x + 5 = 3           {subtract 5 from both sides}

            -3x = 3 - 5

            -3x = -2           {Divide both sides by (-3)}

              x = -2/-3

               x = 2/3
