Answer:

one solution: (1.-4)

Step-by-step explanation:

y = 2x - 6...... (1)

y = -x-3......(2)

Plug y = -x-3 in equation (1)

2x - 6 = - x - 3

2x + x = 6 - 3

3x = 3

x = 3/3

x = 1

Plug x = 1 in equation (2)

y = - 1 - 3

y = - 4

(x, y) = (1, - 4)

Answer:

2(x²-13)

Step-by-step explanation:

Answer:

a) m + n + e3 + ( -2n)  +  10m  =  11m - n + e3

b) x + 2y -4y + 6x + 2x = 9x -2y

c) a + b + c + 2a + 3c -2a + 3b + 4c = a + 4b + 8c

d) 2a  -b + 3c -2a + 3b + 2c = 2b + 5c

Step-by-step explanation:

En cada uno de los casos:

1) Reorganizas los términos

2) sumas los coeficientes de los términos semejantes

a)  m + n + e3 + ( -2n)  +  10m

1) Reorganizando los términos

m + 10m + n + ( -2n)  + e3

2) Sumando los coeficientes de los términos semejantes

(1 + 10) m + (1 - 2) n + e3

(11)m + (-1)n + e3

11m - n + e3

b)  x + 2y - 4y + 6x + 2x

1) Reorganizando los términos

x + 6x +2x + 2y - 4y

2) Sumando los coeficientes de los términos semejantes

(1 +6 +2) x + (2- 4) y

(9) x + (-2)y

9x -2y

c)  a + b + c + 2a + 3c -2a + 3b + 4c

1) Reorganizando los términos

a + 2a - 2a  + b + 3b + c + 3c + 4c

2) Sumando los coeficientes de los términos semejantes

(1 + 2 - 2 ) a + (1  +3) b + ( 1 + 3 +4) c

(1) a + (4)b + (8)c

a +4b + 8c

__________________

d)  2a -b + 3c -2a + 3b + 2c

1) Reorganizando los términos

2a - 2a - b + 3b + 3c +2c

2) Sumando los coeficientes de los términos semejantes

(2 - 2) a + (-1 +3) b + (3 +2)c

(0) a + (2) b + (5) c

2b + 5c

Answer:

i got 32square feet (yes i got it right).

Step-by-step explanation:

The amount of sand will there after the flower bed is installed is,

⇒ 18.5 feet²

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

At schools art teacher designs a circular flower bed inside a rectangular sandbox.

Here, We have;

The sandbox is 6 feet wide and 10 feet long.

Now, We get;

⇒ Radius of circle = 5 feet

Hence, Area of circle = πr²

⇒ Area of circle = 3.14 × 5²

⇒ Area of circle = 78.5 cm²

And, Area of rectangular sandbox is,

⇒ 10 × 6

⇒ 60 feet²

Thus, There will be after the flower bed is installed = 78.5 - 60

                                                                               = 18.5 feet²

Answer:

  False

Step-by-step explanation:

Corresponding angles in similar triangles are congruent. The similarity statement tells you angle B corresponds to angle Y, so those angles are congruent. The sines of congruent angles are identical.

  sin(B) > sin(Y) . . . . FALSE

  sin(B) = sin(Y) . . . . true

Answer:

The answer is true.

Step-by-step explanation:

Answer:

x < -15*C (I can’t make the degrees sign on my iPad, so I put * instead).

3 Possible Answers:

-38*C

-26*C

-57*C

Step-by-step explanation:

Inequality:

x = temperature

< = less than

-15*C = the amount the temperature was less than

3 Possible Outcomes:

Because the temperature is less than -15*C, it can literally be any number that is farther down the number line. Because it’s a negative number, anything like -14, -13, -12, and so on would actually have a greater value (think of it as in being less in debtm or in this case, less below zero). Instead, you’ll do any number like -16, -17, -18, and so on. You can even do a decimal number, like -19.5. I hope this makes sense to you!

Answer:

Rule: replace x by x - a where a is the number of units that you want to move right. a must be greater than 0. x - - a  would move left.

Step-by-step explanation:

You want f(x) to move 3 units to the right.

That would mean that  x would be replaced by x - 3.  Just to be sure let's try it.

The solution is, the following statement is, False.

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

here, we have,

given that,

Triangle ABC is similar to triangle WYZ.

now, we get,

Corresponding angles in similar triangles are congruent.

The similarity statement tells you angle B corresponds to angle Y,

so those angles are congruent.

The sines of congruent angles are identical.

so, we have,

 sin(B) > sin(Y) . . . . FALSE

 sin(B) = sin(Y) . . . . true

Hence, The solution is, the following statement is, False.
