I use a app on my phone called (photòmath) and it helps so much.

Answer:

Assume x is directly proportional to y :

[tex]y \: \alpha \: x \\ y = kx[/tex]

when y is 9, x is 2:

substitute to find value of k :

[tex]9 = (k \times 2) \\ k = \frac{9}{2} [/tex]

Therefore, equation is:

Solution

x=1

x=−6

Step-by-step explanation:

x(+3)+2(x+3)=12

Answer: Sol={-6,1}

Step-by-step explanation:

1) we are searching value of x in R

[tex](x+2)(x+3)=12\\x^2+2x+3x+6-12=0\\x^2+5x-6=0\\\\x^2-x+6x-6=0\\\\x(x-1)+6(x-1)=0\\\\(x-1)(x+6)=0\\\\x=1\ or\ x=-6\\Sol=\{-6,1\}\\[/tex]

2) we are searching value of x in Z.

12=1*12 =(-1)*(-12)

12=2*6=(-2)*(-6)

12=3*4=(-3)*(-4)

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division.

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it. Let us understand how to write expressions. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

Given: ABC is equilateral triangle.

AD = DB   & BE = EC   & CF = FA ------------(IV)

Proof:

  D & F are midpoint of the sides AB and AC

Answer:

I think d is not a binomial from the option given

The equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2, 4) is y = [tex]-\frac{5}{x} x-1[/tex]

Parallel lines have the same slope. Therefore, using slope intercept form.

y = mx + b

m = slope

b = y-intercept

Therefore,

5x + 2y = 12

2y = -5x + 12

[tex]y = -\frac{5}{2} x+12[/tex]

The slope of the line is [tex]-\frac{5}{2}[/tex]

Base on parallelism, for the line that passes through (-2, 4)

y = mx + b

4 = [tex]-\frac{5}{2} (-2)+b[/tex]

b = -1

Step-by-step explanation:

$44 + ($4*67) = Total_num_of_money

$4*67 = $268

$268 + $44 = $312

Chow,...!

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The total ticket sales.

= Total sales at the door + Total sales of advance tickets

= $268 + $44

The total ticket sales amount to $312.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 4 is an equation.

3x + 4 is an equation.

We have,

Total amount sold for advance tickets = $44

The number of tickets sold at the door = 67

Cost of the tickets sold at the door = $4

The total amount sold at the door.

= 67 x $4

= $268

Now,

The total ticket sales.

= Total sales at the door + Total sales of advance tickets

= $268 + $44

= $312

Thus,

The total ticket sales.

= Total sales at the door + Total sales of advance tickets

The total ticket sales amount to $312.

Step-by-step explanation:

(x+3)(x+3) - 4x - 12 - 12

x² + 3x + 3x + 9 - 4x - 24

x² + 2x - 15

(x + 5) (x - 3)

Step-by-step explanation:

Sum of supplementary angle = 180⁰

2x + 12 + 7x - 3 = 180

9x + 9 = 180

9x = 180 - 7

9x = 171

x = 171/9

x = 19

m<3 = 7(19) - 3 = 133 - 3 = 130⁰

m<4 = 2(19) + 12 = 50⁰
