Answer:

[tex]y = -x - 7[/tex].

Step-by-step explanation:

Slope of the given line segment:

[tex]\begin{aligned} m_{1} = \frac{(-5) - (-1)}{(-6) - (-2)} = 1\end{aligned}[/tex].

The slope of any line perpendicular to this line segment would be:

[tex]\begin{aligned}m_{2} &= \frac{-1}{m_{1}} = -1\end{aligned}[/tex].

Midpoint of the given line segment:

[tex]\displaystyle \left(\frac{(-2) + (-6)}{2},\, \frac{(-1) + (-5)}{2}\right)[/tex].

Simplifies to get:

[tex](-4,\, -3)[/tex].

Find the equation of the perpendicular bisector in point-slope form and simplify.

[tex]y - (-3) = (-1)\, (x - (-4))[/tex].

[tex]y + 3 = -x - 4[/tex].

[tex]y = -x - 7[/tex].

Answer:

Step-by-step explanation:

(x + 200)20 = 200(10) + x(40)

Answer:

y=2x-5/2

Step-by-step explanation:

f(x)=(2x+5)/4

y=(2x+5)/4

-----------------

x=(2y+5)/4

2y+5=4*x

2y+5=4x

2y=4x-5

y=4/2x-5/2

y=2x-5/2

The number of tables with 4 chairs are 39.

We have a café which has 60 tables. 35% of the tables have 2 chairs at each table. The remaining 65% of the tables have 4 chairs at each table.

We have to determine the number of tables having 4 chairs.

The 10% of 250 will be -

[tex]\frac{10}{100} \times 250[/tex] = 25

According to question, we have -

Percentage of tables with 2 chairs = 35%

Percentage of tables with 4 chairs = 65%

Total number of tables = 60

Therefore -

Number of tables with 2 chairs = [tex]\frac{35}{100} \times 60[/tex] = 21

Therefore, number of tables with 4 chairs will be = 60 - 21 = 39

Hence, the number of tables with 4 chairs are 39.

There are 39 tables that have 4 chairs.

i.e. the number  of tables with 4 chairs is: 39.

Here, we have to find the number of tables that have 4 chairs, we first need to calculate how many tables have 2 chairs, and then subtract that number from the total number of tables.

Given that 35% of the tables have 2 chairs, we can calculate the number of tables with 2 chairs as follows:

Number of tables with 2 chairs = 35% of 60 tables

Number of tables with 2 chairs = 0.35 * 60

Number of tables with 2 chairs = 21 tables

Now, to find the number of tables with 4 chairs:

Number of tables with 4 chairs = Total number of tables - Number of tables with 2 chairs

Number of tables with 4 chairs = 60 tables - 21 tables

Number of tables with 4 chairs = 39 tables

So, there are 39 tables that have 4 chairs.

Each case contains 80 butterfly kits.

Unitary method is a mathematical technique for finding the value of a single unit and then deriving the given unit by multiplying with it.

According to the given question Ms. Rivera ordered 6 cases of butterfly kits last year out of which the school used 417 of the butterfly kits and had 63 left over after the festival.

So, the total no. of butterfly kits is (417+63) = 480 kits and it was contained in 6 boxes.

∴ The no. of butterfly kits in each case is 480/6 which is

= 80 butterfly kits.

The width of the mat around the photo is 3 inches

The combined area of the of the photo and math = 224 square inches

The combined area is represented as:

(2w +8)(2w + 10) = 224

Expand the equation using the distributive rule

[tex]4w^2+20w+16w+80=224\\\\4w^2+36w+80-224=0\\\\4w^2+36w-144=0[/tex]

Divide through by 4

[tex]w^2+9w-36=0[/tex]

Factorize the resulting quadratic equation to solve for w

The width of the mat around the photo is 3 inches

Combined area:

2w +8)(2w + 10) = 224

where,

w = width of the mat around the photo

(2w +8)(2w + 10) = 224

open parenthesis

4w² + 20w + 16w + 80 = 224

4w² + 36w + 80 - 224 = 0

4w² + 36w - 144 = 0

divide through by 4

w² + 9w - 36 = 0

solve quadratic equation using factorization method

w² + 12w - 3w - 36 = 0

w(w + 12) - 3(w + 12) = 0

(w + 12) (w - 3) = 0

w + 12 = 0 or w - 3 = 0

w = -12 or w = 3

The width of the mat around the photo cannot be a negative value.

Step-by-step explanation:

235 + 23

She uses 235, so 23 is left

235 + something + something = 235 + 23

235 + 20 + something = 235 + 23

subtract 235 from both sides

20 + something = 23

20 + something = 20 + 3

The missing number is 3.

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

Kenya uses mental math to find the sum of 235 and 23.

She uses mental math.

That means,

she breaks the term in simple manner.

And she uses 235, 20, and one other number.

And the other number is 23 - 20 = 3

So, addition,

235 + 23

= 235 + 20 + 3
