-18 is the y intercept

The slope is in y=mx+b form,

And b is the y intercept. Mx is the slope(m) and x is the variable, in this case 8x

So slope is 8, and y intercept is -18

Suppose that the number of the people in the party is :

[tex]x[/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

20 % of x equals :

[tex] \frac{20}{100} \times x = 0.2x \\ [/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Thus ;

[tex]0.2x = 6[/tex]

[tex] \frac{2}{10}x = 6 \\ [/tex]

Multiply sides by 10

[tex]10 \times \frac{2}{10} x = 10 \times 6 \\ [/tex]

[tex]2x = 60[/tex]

Divided sides by 2

[tex] \frac{2}{2} x = \frac{60}{2} \\ [/tex]

[tex]x = 30[/tex]

There were 30 people in the party.

Thus there are ;

[tex]30 + 6 = 36[/tex]

People at the party now.

The required retail cost of the hat before the markup is 11.73.

Given that,
Monty buys hats in bulk to sell at his store. His cost for each hate is $17. He marks up the hats 45%. What is the retail price per hat is to be determined.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
Let the retail cost be x,
According to the question, the retail price is markup by 45%.
So the cost after mark up = x + 0.45x = 1.45x
And
17 = 1.45x
x = 17 / 1.45
x = 11.73

Thus, the required retail cost of the hat before the markup is 11.73.

Step-by-step explanation:hope that helps :)))

x2+6x=−5

x2+6x−(−5)=−5−(−5)(Subtract -5 from both sides)

x2+6x+5=0

(x+1)(x+5)=0(Factor left side of the equation)

x+1=0 or x+5=0(Set factors equal to 0)

x=−1 or x=−5

Answer:

6x-2

Step-by-step explanation:

Celia’s simplified expression:

6x - 2.

The last option is  correct.

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Given Phrase:

Celia simplified the expression Negative 4 x (1 minus 3) minus (2 x + 2).

That means,

-4x(1 -3) - (2x +2).

She checked her work by letting x = 5 in both expressions.

That means,

-4(5)(1 -3) - (2(5) +2).

= 40 - 12

= 28.

To find the simplified expression:

-4x(1 -3) - (2x +2),

= 6x - 2.

Therefore, the required expression is 6x - 2.

Answer: 7 units left and 6 Units Up.

Step-by-step explanation:

All you have to do is measure the distance, on the chart which in my answer. Its right BTW I alr did it. ;)

The transformation of polygon ABCD to form A'B'C'D' is 7 units left and 6 units up thus option (A) will be correct.

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

As per the given polygon,ABCD

A(4,-2),B(6,-4),C(2,-5),D(2,-3)

The transformed polygon A'B'C'D'

A'(-3,4),B'(-1,2),C'(-5,1),D'(-5,3)

The original polygon ABCD and its transformed A'B'C'D have been drawn below.

f we look then it is clear that the transformed image is not rotated about any axis.

Now consider a point A(4,-2) and A'(-3,4)

4 + x = -3 → x = -7 (7 units left)

-2 + y = 4 → Y = 6 (6 units up)

Hence "The transformation of polygon ABCD to form A'B'C'D' is 7 units left and 6 units up".

Answer:

a=-5, k=31

Step-by-step explanation:

Determine a and k so the given points are on the graph of the function:

(1,11) (2,-14)

[tex]y=a(x+1)^2+k[/tex]

To find the required values, we substitute the points into the equation:

[tex]11=a(1+1)^2+k[/tex]

[tex]-14=a(2+1)^2+k[/tex]

Operating:

[tex]11=a(2)^2+k[/tex]

[tex]-14=a(3)^2+k[/tex]

Simplifying:

[tex]11=4a+k[/tex]

[tex]-14=9a+k[/tex]

Subtract the second equation from the first equation:

[tex]11+14=4a-9a[/tex]

Simplifying:

[tex]25=-5a[/tex]

Solving:

[tex]a=25/(-5)=-5[/tex]

a=-5

Use this equation to find k:

[tex]11=4a+k[/tex]

[tex]11=4(-5)+k[/tex]

[tex]11=-20+k[/tex]

k=31

a=-5, k=31

Answer:

a = -5

k = 31

Answer:

The translation is left 1 unit, up 5 units ⇒ A

Step-by-step explanation:

Let us revise the rules of translation of a function

The vertex form of the quadratic function is f(x) = ax² + bx + c, where a, b, and c are constant is f(x) = a(x - h)² + k, where h = [tex]\frac{-b}{2a}[/tex]  and k = f(h)

You will use the vertex form to find the translation

∵ g(x) = x² + 2x + 6

∴ a = 1 and b = 2

→ use the rule of h to find it

∴ h = [tex]\frac{-2}{2(1)}=\frac{-2}{2}[/tex]

∴ h = -1

→ Use it to find k

∵ g(h) = k

∴ k = g(-1)

→ Substitute x by -1 in g to find k

∴ k = (-1)² + 2(-1) + 6 = 1 - 2 + 6

∴ k = 5

→ Substitute the values of h and k in the vertex form above

∴ g(x) = 1(x - -1)² + 5

∴ g(x) = (x + 1)² + 5

→ By using the 2nd and 3rd rules of translation above

∴ f(x) is translated 1 unit to the left and 5 units up

∴ The translation is left 1 unit, up 5 units

The translation that maps the graph is mathematically given as

"The translation as left 1 unit, up 5 units"

Translation is simply defined as the communication of the meaning of source content into target-content.

Generally, the equation for the  vertex form  is mathematically given as

g(x) = x² + 2x + 6

Where

a = 1 and b = 2 and h=-1

g(h) = k

k = g(-1)

k = (-1)² + 2(-1) + 6

k= 1 - 2 + 6

k = 5

In conclusion

g(x) = (x + 1)^2 + 5

Giving the translation as left 1 unit, up 5 units
