Answer:

The answer should be A'(-9,3) B'(12,-6)

Step-by-step explanation:

If you dialate, you multiply every coordinate by 3. -3 x 3= -9. 1 x 3=3. 4 x 3= 12. -2 x 3= -6. So, the last option is correct.

10% of the movies, because 100/40 is 2.5 so you would do 4 x 2.5 which equals 10. AKA
So if you’re trying to change it to x/100, you would do cross division and get 10/100 which equals 10%

Fill in the blank with a constant, so that the resulting quadratic expression is the square of a binomial. $\[x^2 + 22x + \under

saw5 [17]

Answer:

$\[x^2 + 22x + 121\]$

Step-by-step explanation:

Given

$\[x^2 + 22x + \underline{~~~~}.\]$

Required

Fill in the gap

Represent the blank with k

$\[x^2 + 22x + k\]$

Solving for k...

To do this, we start by getting the coefficient of x

Coefficient of x = 22

<em />

Divide the coefficient by 2

$Result = 22/2$

$Result = 11$

Take the square of this result, to give k

$k= 11^2$

$k= 121$

Substitute 121 for k

$\[x^2 + 22x + 121\]$

The expression can be factorized as follows;

$x^2 + 11x + 11x + 121$

$x(x + 11)+11(x+11)$

$(x+11)(x+11)$

$(x+11)^2$

<em>Hence, the quadratic expression is </em> $\[x^2 + 22x + 121\]$ <em></em>

An employment agency specializing in temporary construction help pays heavy equipment operation $138 per day and general laborer

ki77a [65]

<h3>17 heavy equipment operators and 14 general labourers were employed</h3>

<em><u>Solution:</u></em>

Let x = number of heavy equipment operators employed

Then,

31 - x = number of laborers employed

From given,

Pay of heavy equipment operators = $ 138 per day

Pay of general labours = $ 93 per day

Payroll was $3648

Therefore,

number of heavy equipment operators x Pay of heavy equipment operators + number of laborers employed x Pay of general labours = 3648

138x + 93(31 - x) = 3648

138x + 2883 - 93x = 3648

45x = 3648 - 2883

45x = 765

x = 17

Thus,

31 - x = 31 - 17 = 14

Therefore, 17 heavy equipment operators and 14 general labourers were employed

What is the slope of the line in the graph?

SVEN [57.7K]

Answer:

Slope = 1

Step-by-step explanation:

While there are multiple methods to deducing slope, the one I used for this equation is y/x. Starting at the y-intercept, draw a line up as many increments until you align horizontally with another point. Then, draw a line horizontally (towards the line) until you meet that point. Continue this pattern up the line. Each movement will fall in a patterned number, such as 3 up and 1 left or right. 'Up' becomes 'Y' as you are moving on the y-axis, and 'horizontally' or 'left/right' becomes 'X' as you are moving on the x-axis. Pull these numbers into the fraction y/x. If the fraction equals a whole number, translate the fraction into that number. If not, keep it in fraction form (such as 1/3 or 1/4). In this instance, it would become 3/1 and then 3. This number is now your slope.

Here I attached the same practice to your graph (in desmos) and showed how it becomes 1/1 and then 1.

What figure can be made using the net shown?

Readme [11.4K]

Answer:

Correct option: First one -> Hexagonal prism

Step-by-step explanation:

In the figure we have two hexagons and six rectangles. If we fold each part correctly, we can use the two hexagons as horizontal bases of a prism, and the six rectangles would be the sides of the prism (each rectangle connected to one side of lower hexagon and one side of upper hexagon).

So the figure created would be a hexagonal prism.

Correct option: First one.
