Answer:

k=3

Step-by-step explanation

1.)Group like terms 2+6k-18= -3k+11

2.)Add/Subtract the numbers 2-18=-16 6k-16= -3k+11

3.)Add 16 to both sides

4.)Simplify 6k=-3k+27

5.)Add 3k to both sides

6.)Simplify 9k=27

7.)Divide both sides by 9

8.)Simplify k=3

Answer:

28 + 12x

Step-by-step explanation:

Perimeter= all sides added

Square= 4 same length sides

4(7 + 3x) = 28 + 12x

Answer:

y=9

Step-by-step explanation:

Plugin what we know

[tex]\frac{y}{12} =\frac{3}{4}[/tex]

Simplify the equation by using cross-multiplication

4y=36

Divide both sides of the equation by 4

y=9

If this helped, please rank me brainliest! :)

Answer:

Y would be 9

Step-by-step explanation:

If the x is 12 and it shows the simplified version take the 4 and multiply it by how much you would need which is 3 so you go to the 3 above 4 and multiply it by 3 and you will get 9/12

Sorry if its a bit hard to understand but hope this helps!

Answer:

The graph f(x)=[tex]-2(x+3)^2-4[/tex] is a reflection over the x-axis, vertical stretch by a factor of 2, a horizontal translation left 3 units and a vertical translation 4 units down of the graph y=[tex]x^2[/tex].

Step-by-step explanation:

The graph f(x) is reflected over the x-axis because the negative is outside of the parenthesis.

it's a vertical stretch by a factor of 2 because 2 is outside of the parenthesis and is greater than 1.

(x+3) is a horizontal translation left 3 units because it is inside the parenthesis.

-4 is vertical translation 4 units down because it is outside of the parenthesis.

Answer: a) Y= 2|x-3|+1

Step-by-step explanation:

Hope this helps

The equation that describes the graph is the one in option a:

f(x) = 2*|x - 3| + 1

We can see that the graph is an absolute value equation with a vertex in the point (3, 1), so the absolute value function must be of the form:

f(x) = a*|x - 3| + 1

Now, we also can see that the arms open upwards, so the slope must be positive, and we can see that for each increment in x, we have an increment of 2 units in y, so the slope is a = 2.

This means that the function is:

f(x) = 2*|x - 3| + 1

So the correct option is a.

Answer:

-12a - 48

Step-by-step explanation:

you do -6 times 2a which is -12a then you do -6 times 8 which gives you -48 so you put -12a - 48

since the 48 is a negative we would just put a minus sign instead a plus. If it was a positive 48 we would put a plus sign buts its not so we put a negative.

[tex]\huge\boxed{\mathcal{HELLO!}}[/tex]

The distributive property states that

a(b+c)=ab+ac (we multiply a by everything inside the parentheses)

the unknown number is -12, 41+7=48  

48/-4=-12

Answer:

First, you look at the y-intercept. It is positive 6 so you start at 6 on the y-axis. Then you look at the slope. It is negative 1/4. It is negative so the slope goes down and it goes down on the unit and 4 units right. That is how you graph y= -1/4x + 6

Answer:

She can buy a maximum number of 15 containers

Step-by-step explanation:

We are told from the question that:

Mrs. Phan needs at least 5 containers of tulips and at least 5 containers of lilies.

Tulips cost $6 per container and lilies cost $4 per container. If Mrs. Phan has a total of $75 to spend for the tulips and lilies, what is the greatest number of containers she can buy?

Let x represent the number of Can of tulips for both tulips and lilies

x ≥ 5 cans for both tulips and lilies

$6 × x + $4 × x = $75

6x + 4x = 75

10x = 75

x = 75/10

x = 7.5 cans

This means , 7.5 containers for tulips and 7.5 containers for lilies

Adding up both containers, we have :

7.5 + 7.5 = 15 containers

Therefore, the greatest number of containers she can buy is 15 containers

Answer:

(-10,-3)

Step-by-step explanation:

okay so first, we can plot the points (-3,2) and (4,7) on a graph. after graphing these points, look at the difference between the y-values. this is 5 because 7-2 is 5. now, look at the x-values. this is 7 because 4-(-3) is 7. so this means we have to go on the other side of the midpoint (-3,2) and go 5 lines down from that point. this brings us at (-3,-3). now, we have to go 7 lines to the left. this is (-10,-3). this is the other endpoint.

you can also graph this on desmos to double-check.

Answer:

Step-by-step explanation:

After being rotated by 90 degrees, the figure has 4 pairs of parallel sides.

What is 90° rotation of an object?

The transformation P(x, y) P' can be used to represent a 90° rotation for any point in the plane (x, y) (-y, x). This transition can be produced by applying two reflections.Transformation involves moving a shape from one position to another  

Given data ,

A figure with 4 sets of parallel sides is graphed on a grid

The figures with 4 sets parallel sides are : Rhombus, Square , Rectangle

The figure is then rotated 90° clockwise

Now ,

90 degrees clockwise transformation carries the square , rhombus as well as the rectangle onto itself that is after rotation there will be 4 pairs of parallel sides

Hence , after being rotated by 90 degrees, the figure has 4 pairs of parallel sides.
