Answer:

the range is from 6 to -4 (both inclusive)

Step-by-step explanation:

the domain is all values of x for which the function is defined and the range is all values of y for which the function is defined hence the domain is -3 to -11 and the range is 6 to -4

Answer:

x = -3

Equation: 2x + 2 = -4

x = 2

Equation: 3x - 3 = 3

Answer:

Step-by-step explanation:

(21 + 3y) + y = 90

21 + 4y = 90

4y = 69

y = 17.25

x = 21 + 3(17.25)

x = 21 + 51.75

x = 72.75

Answer check:

72.75 + 17.25 = 90

90 = 90 Corrrrrrect !

Step-by-step explanation:

Two shapes are congruent when they are the same shape and size. Its obvious that both are rectangles and if we look at the grid, we can see that both rectangles are 2 by 4. Since they both have the same shape and size, they are in fact congruent.

Answer:

The united nations flag the translation can be any of the blue triangles and the reflection if the flag itself as it is symmetrical

Step-by-step explanation:

The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.

When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.

If we study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.

If you're reflecting a point (x,y) along x axis, then its abscissa will stay same but ordinates will negate. Thus (x,y) turns to (x, -y)

Similarly, if you're reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)

Therefore, The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.

Step-by-step explanation:

r = kp/(st)

p = 12, t = 2, s = 5, r = 18

18 = k(12)/(2)(5)

18 = 12k/10

12k = 180

k = 15

Answer:

135 tickets

Step-by-step explanation:

Vie's brother sold twice as many as Vie. So we multiply Vie's tickets by 2 to get the brother's.

VIe's brother sold 45 * 2 = 90 tickets

And all together the two sold

45 + 90 = 135 tickets

Step-by-step explanation:

I only see one phrase (correcting a typo) : "five more than a number".

that is expressed in math by using "n" for the variable "number " :

n + 5

or

5 + n

as additions and multiplications are commutative, they can be written and executed in any sequence. it is always the same result.

Answer:

Length=13.07 and Breadth=1.07

Step-by-step explanation:

Area=l*b

14=(2x+5)(2x-7)

14=4x^2-4x-35

4x^2-4x-49=0

Using quadratic formula, we have x=(1±5sqrt(2))/2 but as length can't be negative, so x=(1+5*sqrt(2))/2

Length=13.07 and Breadth=1.07

Answer:

Step-by-step explanation:

Most people are going to say 4x2=8 so 20x2=40, then do a huge math mess up and think they discounting $1.33 after the first 4. this is incorrect.

Seeing as $20 is 4 tickets we can safely say, each ticket is $5 each.

Basic mathematics, 5x7=35. Paying for 7 tickets at $5 each, that is the correct constant price.
