Answer:

h(x) ≥ |x - 5| +1

Step-by-step explanation:

Given graph represents an absolute function (parent function)

f(x) = |x|

Since, graph of the function 'f' has been shifted 5 units to the right new function will be,

g(x) = f(x - 5)

g(x) = |x - 5|

Again function 'g' is shifted 1 unit upwards along the y-axis then the new function will be,

h(x) = g(x) + 1

h(x) = |x - 5| + 1

There is a shaded region representing the solution area lying above the intersecting dark lines,

Therefore, solution region will be re[presented by the inequality,

h(x) ≥ |x - 5| + 1

Answer:

8.236%

Step-by-step explanation:

P(G,G,G) = 8/17 x 7/16 x 6/15

= 7/85 (simplified)

7/85, in decimal form, is .082352

.082352 in percent form is 8.236%

Answer:

B) 24

Step-by-step explanation:

The area of the rectangle is 48 units (8 x 6).

The base of the is 6 units and the height is 8 units. The formula for the are of a triangle is A = [tex]\frac{1}{2}[/tex]bh.

b = base

h = height

A = [tex]\frac{1}{2}[/tex](6)(8)

A = 24

Answer:

[tex]24[/tex]

Step-by-step explanation:

If the area of a rectangle is bh, and the area of a triangle is bh/2, then a triangle's area is half a rectangle's area. Hence, if the area of the rectangle is 48, the area of the triangle is half of 48, or 24.

Answer:

-5n² - 8n + 4

Step-by-step explanation:

Given the expression

(3n²– 5n + 6) + (–8n²– 3n – 2)

Expand the bracket

3n²– 5n + 6 –8n²– 3n – 2

Collect the like terms

3n²-8n²-5n– 3n – 2+6

-5n² - 8n + 4

This gives the required result

C: -5n^2 - 8n + 4

The answer to the second question is 4, 11, and 5.

[tex]a + c = 180 - 65 = 115[/tex]

Answer:

A

Step-by-step explanation:

∠4 and ∠8 are corresponding angles

corresponding angles are congruent ( equal to each other )

so if ∠4 = 100° then ∠8 also equals 100°

Answer:

A

Step-by-step explanation:

8 is equal to 4(100) because it is corresponding angle, corresponding angle are equal to each other...If 4 is 100 then 8 will be 100

Answer:

10 guests

Step-by-step explanation:

Devin wants to play lazer tag for his birthday. He is comparing the cost of two companies.

Let us represent additional guests = g

Lazer Zone charges $50 for parties, and an additional $10 per guest.

=$50 + $10 × g

50 + 10g

For fun place

Fun Palace charges $90 for parties, and an additional $6 per guest.

= $90 + $6 × g

90 + 6g

For how many ?

We equate both Equations together

= 50 + 10g = 90 + 6g

Collect like terms

10g - 6g = 90 - 50

4g = 40

g = 40/4

g = 10

Hence, g = 10 guests

Therefore, the number of guests for which the cost of both companies is the same is 10 guests

Answer:

The total number of child ticket sold  = 87

The total number of adult ticket sold = 128

Step-by-step explanation:

Given -  The local theatre performed a Saturday matinee to a crowd of 215 people. Tickets cost $11 child and $15 per adult, bringing in a total of $2877.

To find - Use an inverse matrix to determine the number of each type of ticket sold .

Proof -

Let the total number of child ticket sold = x

Let the total number of adult ticket sold = y

Given that, The local theatre performed a Saturday matinee to a crowd of 215 people.

⇒x + y = 215

Also,

Given that,  Tickets cost $11 child and $15 per adult, bringing in a total of $2877

⇒11x + 15y = 2877

So,

The equations becomes

x + y = 215

11x + 15y = 2877

So,

The matrix form becomes

[tex]\left[\begin{array}{ccc}1&1\\11&15\end{array}\right]\left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}215\\2877\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}1&1\\11&15\end{array}\right| \left\begin{array}{ccc}215\\2877\end{array}\right ] \\\left[\begin{array}{ccc}1&1\\0&4\end{array}\right| \left\begin{array}{ccc}215\\512\end{array}\right ] \\\left[\begin{array}{ccc}1&1\\0&1\end{array}\right| \left\begin{array}{ccc}215\\128\end{array}\right ]\\\left[\begin{array}{ccc}1&0\\0&1\end{array}\right| \left\begin{array}{ccc}87\\128\end{array}\right ][/tex]

By comparing, we get

x = 87

y = 128

So, we get

The total number of child ticket sold = x = 87

The total number of adult ticket sold = y = 128

Answer:

64

Step-by-step explanation:

add them all up firstly to get 701

then divide by how many are there (11)

then you will get 63.72

and you need to round up since the decimal is a 7

which that gives you 64

Answer:

x = 30

Step-by-step explanation:

correct me if i am wrong but i think you have to

a.) change the denominator's to be the same :

ten is a common denominator therefore you times the second expression by two ( x/5 becomes 2x/10 )

b.) put the formula back together :

3x/10 + 2x/10 = 15

5x/10 = 15

5x = 150

x = 30

Answer:

Third zero is 4

Step-by-step explanation:

The polynomial is;

f(x) = x³ − 4x² − 3x + 12

We are given 2 zeros which are √3 and -√3.

This means that a factor of the polynomial will b; (x² - 3) because when it is equated to zero, x will be √3 and -√3.

Now, to get the other factor of the polynomial, we have to divide x³ − 4x² − 3x + 12 by (x² - 3) using long division method.

I have attached this long division method and we have the third factor as; (x - 4)

Equating to zero, we have x = 4 as the third zero of the polynomial
