Answer:
Option C is correct answer.
Step-by-step explanation:
We need to draw the graph of piece wise function
[tex]f(x)\[ \begin{cases} -2-x & if\:x\leq 1 \\ -3+2x & if\: x>1 \end{cases}\][/tex]
So, for drawing the graph, we will find values of f(x) for both the given equations.
First finding f(x) for [tex]-2-x \:\: if\:x\leq1[/tex]
The value of x must be less than or equal 1
x f(x)
1 -3
0 -2
-1 -1
-2 0
-3 1
-4 2
The graph will start from closed circle because x ≤ 1
Now, finding values of f(x) for [tex]-3+2x\: if\:x>1[/tex]
The value of x must be greater than 1
x f(x)
2 1
3 3
4 5
5 7
The graph will start from open circle because x> 1
Now, plotting these numbers we will get graph of Option C.
Option C is correct answer.

Answer:
[tex]m\angle N=57^{\circ}[/tex]
Step-by-step explanation:
From the isosceles-base theorem, the measure of the angles adjacent to the pair of congruent sides of the triangle are equal. Since the problem declares [tex]LM\cong LN[/tex], the remaining unknown angles are equal ([tex]m\angle N=m\angle M[/tex]). The sum of the interior angles of a triangle always add up to [tex]180^{\circ}$[/tex].
Therefore:
[tex]m\angle N\cdot 2+66=180,\\m\angle N\cdot 2=114,\\m\angle N=\fbox{$57^{\circ}$}[/tex] .
Answer:
LMN is rectangle in L so LMN= 180° ; ML=66°;N=? N= 180°- 66°=114=114/2= 57° so N=57°
Step-by-step explanation:
When the angle at the top is close to 0 °, the two of the base get less than 180 °, or less than 90 ° for each. If the angle at the top is 60 °, the other two are: 180 - 60 = 120 °, and each is: 120/2 = 60 °.

Step-by-step explanation:
1 I am thinking of a 6-digit number. • The sum of the digits is 38. • The number is under 600 000. What could my number be? Find twelve different possibilities.
Answer:
A 6 digit number can be written as:
abcdef
Where each letter represents a single digit.
We know that this number is smaller than 600,000, and we also know that:
a + b + c + d + e + f = 38
Now, we have a lot of variables, so we can play a little.
I will suppose that:
f = 6
e = 7
d = 3
c = 9
then we have:
a + b + 9 + 3 + 7 + 6 = 38
a´+ b + 25 = 38
a + b = 38 - 25 = 13
now let's suppose that b = 8
a + 8 = 13
a = 13 - 8 = 5
Then our number is:
589,376
This number is smaller than 600,000, and if we add the sum of the digits is 38.
Now we want to find 11 other numbers like this.
We can simply change the places of some of the digits, like:
598,376 (also meets the condition)
Where i just changed the positions of the 9 and the 8.
589,367 (also meets te condition)
Where i just changed the position of the 6 and 7.
Now just keep doing that, only take care that the number can not be larger than 600,000, so i will leave the first 5 fixed in that position.
589,673 (also meets the condition)
598,736 (also meets the conditions)
536,798 (also meets the conditions)
536,897 (also meets the conditions)
536,978 (also meets the conditions)
563,798 (also meets the conditions)
563,987 (also meets the conditions)
563,879 (also meets the conditions)
573,689 (also meets the conditions)
573,869 (also meets the conditions)

Ja'kniya and Alayjah are shopping at the Apple Store. Ja'kniya bought 4 screensavers and 3 Otterboxes for $29. Alayjah bought 6 screensavers and 2 Otterboxes for $26. How much did each screensaver and each Otterbox cost?
Answer: Each screensaver costs $2 and each Otterbox costs $7.
Step-by-step explanation:
Let x = Cost of each screensaver and y = cost of each Otterbox.
As per given, 4x+3y=29 (i)
6x +2y = 26 (ii)
Divide both sides of (i) by 2 and the multiply it by 3 on sides , we get
9x+3y=39 (iii)
Eliminate (i) from (iii) , we get
5x = 10
⇒ x = 2 [Divide both sides by 5]
Put value of x in (i), we get
4(2)+3y=29
⇒ 8+3y= 29
⇒ 3y= 21
⇒ y =7 [Divide both sides by 7]
Hence, Each screensaver costs $2 and each Otterbox costs $7.

If Cathy receives all the discounts (30%, 20%, 10%, 15%, and an additional 20% Holiday Bonus Bucks discount, how much will she pay for the $90 sweater?
Answer:
She will pay $30.8448.
Step-by-step explanation:
Consider the provided information.
The price of the sweater is $90.
She gets a discount of 30% it means she needs to pay only (100-30)%=70% of $90.
70% of $90 = [tex]0.7\times 90 = 63[/tex]
Now she gets a discount of 20% it means she needs to only 80% of $63.
[tex]0.8\times 63=50.4[/tex]
If she gets a discount of 10% on $50.4 it means she needs to pay 90% of 50.4
[tex]0.9\times 50.4=45.36[/tex]
If she gets a discount of 15% on 45.36 it means she needs to pay only 85% of 45.36
[tex]0.85\times 45.36 =38.556[/tex]
Now she gets an additional 20% holiday Bones Buck discount it means she needs to pay 80% of 38.556
[tex]0.8\times 38.556=30.8448[/tex]
Hence, she will pay $30.8448.

Let x represent the number of years in 2004 and y represent the number of catalogs Catalogs. Number in 2004. Growth rate Online. 7440. 1293 Print. 3805. -1364
Answer:
The answer is below
Step-by-step explanation:
a) x represents the number of years since 2004 this means that x = 0 represent the year 2004, y represent the number of catalogs. From the table the numbers of catalogs in 2004 are y-intercepts and the slope is the growth rates. Hence the equations are:
y = 1293x + 7440 (1)
y = -1364x + 3805 (2)
b)
y = 1293x + 7440 (1)
y = -1364x + 3805 (2)
Subtract equation 2 from equation 1 to get:
0 = 2657x + 3635
2657x = -3635
Divide through by 2657
x = -1.368
Put x = -1.368 in equation 1:
y = 1293(-1.368) + 7440
y = 5671.1
This means that about 1.4 years before 2004, the number of catalogs where 5671

Help Link (little green guy on the left) defeat Ganon and save Zelda. Find the distance from Link to the Green Soldier so Link can attack. Press "Submit" to check your work.
Answer: 5 units
Step-by-step explanation:
The shape presented is a triangle and the distance between Link and Ganon is the hypothenuse of that triangle.
This can be calculate using the Pythagoras rule:
c² = a² + b²
c is the hypothenuse.
a in the triangle = base = 4 units
b = height = 3 units
c² = 4² + 3²
c² = 16 + 9
c² = 25
c = √25
c = 5 units

Given:
The expression is
[tex]-5x+4-x-1[/tex]
To find:
The terms, like terms, coefficients and constants.
Solution:
We have,
[tex]-5x+4-x-1[/tex]
It can be written as
[tex]=(-5x)+4+(-x)+(-1)[/tex]
So, terms are [tex]-5x,4,-x,-1[/tex].
It two terms have same variable of same degree, then they are called like terms.
[tex]-5x,-x[/tex] are likes terms because degree of variable is 1 and 4, -1 are like terms because degree of variable is 0.
In the product of a number and a variable, the number is called coefficient.
Variable terms are [tex]-5x,-x[/tex]. So, coefficients are -5 and -1.
Constant terms are free from variable. So, constant terms are 4 and -1.
Terms: [tex]-5x,4,-x,-1[/tex];
Like terms: [tex]-5x, -x;4, -1[/tex];
Coefficients: -5, -1;
Constants: 4, -1
Therefore, the correct option is c.

Answer:
f(x) = 3x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)
m = [tex]\frac{3-0}{1-0}[/tex] = 3 , then
y = 3x ← is the equation of the graphed line
The aquarium where Evan works has a special tank for the baby sharks. The tank is shaped like a rectangular prism and is 18 meters long by 15 meters wide. It is 8 meters from the bottom of the tank to the top. What is the volume of the shark tank?
Answer:
The volume of the shark tank is [tex]2160 m^3[/tex]
Step-by-step explanation:
The tank is in the shape of a rectangular prism.
The length of the tank, [tex]l=18[/tex] m.
The width of the tank, [tex]w=15[/tex] m.
The height of the tank, [tex]h=8[/tex] m.
We know that, volume of a rectangular prism [tex]=l\times w \times h[/tex].
So, the volume of the tank [tex]=18\times 15\times 8=2160 m^3[/tex]
Hence, the volume of the shark tank is [tex]2160 m^3[/tex].
