The expression which is represented by the graph will be -6 -(-1) so the correct option will be (A).
What is the expression?An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In given figure the, one box represents -1
Now there are total 6 box = -1 times 6 = -6
Now the last box is removed it means it should be subtracted from all the box
-6 - ( One box) = -6 -(-1) hence option A will be correct.

Part A
Answers:
Coefficient = 10.50 or 15 (pick one value)Variable = h or c (pick one)Constant = 50------------------
Explanation:
The variables are simply letters. They are placeholders for numbers to be plugged in later. Think of them like empty boxes where numbers will go. In this case, the variable h represents the number of hours Tyler works, and c is the number of new accounts she opens.
The coefficients are the numbers multiplied with the variables. They are to the left of the variable.
The constant 50 is not attached to any variable.
===================================
Part B
Answer: She earns $618.5
-------------------
Explanation:
We're told she worked 37 hours. So we'll replace h with 37.
Also, she opened 12 new accounts. So c = 12
This means...
10.50*h + 15*c + 50
10.50*37 + 15*12 + 50
388.5 + 180 + 50
618.5
is the amount she earns
===================================
Part C
Answer: The coefficient changes. Specifically, the coefficient 10.50 changes to 11.25
-------------------
Explanation:
The constant never changes (hence the name) no matter how much of a raise Tyler gets. The other coefficient doesn't change either because she would still get $15 per new account. All that's changed is the hourly wage.
If we're told that Tyler got a raise to $11.25 per hour and she now earned $20 per new account, then both coefficients would change and the new equation would be 11.25h+20c+50

How to calculate y=6x^2+1
Answers
Hi there!
~
⇒ Graph : [tex]y=6x^2+1[/tex]
∴ Rewrite the equation in vertex form.
⇒ [tex]y = 6 ( x + 0)^2 + 1[/tex]
∴ Use the vertex form, [tex]y = a(x - h)^2 + k[/tex] , to determine the values of [tex]a , h ,[/tex] and [tex]k[/tex]
[tex]a = 6 \\h = 0\\k = 1[/tex]
∴ Since the value of [tex]a[/tex] is positive, the parabola opens up.

∴ Find the vertex [tex]( h,k)[/tex].
[tex](0,1)[/tex]
∴ Find [tex]p[/tex], the distance from the vertex to the focus.
[tex]\frac{1}{24}[/tex]
∴ Find the focus.
[tex]( 0 , \frac{25}{24} )[/tex]
∴ Find the axis of symmetry by finding the line that passes through the vertex and the focus.
[tex]x = 0[/tex]
∴ Find the directrix.
[tex]y = \frac{23}{24}[/tex]
∴ Use the properties of the parabola to analyze and graph the parabola.

Answers
Answer:
1. The star's mass is 3.0 x 10^32 kg.
2. The star's mass is 3.0 x 10^32 kg.
Step-by-step explanation:
1.
given:
The sun's mass is 2.0×10^30 kg.
mass of a star = 1.5×10^2 kg times the mass of the sun.
find:
Express the answer in Scientific notation.
mass of a star = 1.5×10^2 kg X 2.0×10^30 kg
mass of a star = 3.0 X 10^32 kg
therefore,
The star's mass is 3.0 x 10^32 kg.
===============================================
2.
(2.0 X 10^30) X (1.5 X 10^2)
Multiply the coefficients.
= (2.0 X 1.5)
= 3.0
then add the exponents
= 10^30 + 10^2
= 10^32
Combine the results of the two operations.
(2.0 X 10^30) X (1.5 X 10^2) = 3.0 X 10^32
therefore,
The star's mass is 3.0 x 10^32 kg.
===============================================
Answer:
1. The star's mass is 3.0 x 10^32 kg.
2. The star's mass is 3.0 x 10^32 kg.

Katie has a collection of nickels, dimes and quarters with a total value of $3.95. There are 4 more dimes than nickels and 3 more quarters than nickels, how many of each coin does she have?
Answers
Answer:
She has 7 nickels, 11 dimes and 10 quarters
Step-by-step explanation:
Total value =$3.95
Let
Nickel = x
Dimes = x + 4
Quarters = x + 3
Every
Nickel = 5 cents
Dimes = 10 cents
Quarters = 25 cents
Total cents = $3.95 × 100
= $395
5n + 10d + 25q = 395
5(x) + 10(x+4) + 25(x+3) = 395
5x + 10x + 40 + 25x + 75 = 395
40x + 115 = 395
40x = 395 - 115
40x = 280
Divide both sides by 40
x= 280/40
= 7
x= 7
Nickel = x = 7
Dimes = x + 4
=7+4
=11
Quarters = x + 3
=7+3

Janet’s car insurance payment decreases by $20 each year. Which expressions represent the total change in her payment,in dollars, after 5 years A. 20-20-20-20-20 B. 100 c. 5•(-20) d. -20•(-5) E. -100 pls answer my
Answers
Answer:
Option C is the correct answer.
C. 5•(-20)
Step-by-step explanation:
We are told that the insurance payment for the car follows a certain pattern that can be represented through an expression. The payment is decreasing by $20 every year. As we don't know the total payment amount per period, so we cannot calculate how much is paid per period/year for insurance but we can calculate the rate at which this payment is decreasing.
Change in payment = t * (-20)
The above expressions can be used to calculate the amount of change in payment i payment is decreasing by a constant $20 every year, after t years.
So, if we want to calculate the change in payment after say 5 years, we can replace t with 5 in the equation and calculate the change,
Change in payment = 5 * (-20)
Change in payment = - $100

1. Two angles form a linear pair. The measure of
the larger angle is four times the measure of the
smaller angle. What is the larger angle's
measure?
Answers
Answer:
144°
Step-by-step explanation:
let the smaller angle be x then the larger angle is 4x
The sum of a linear pair of angles = 180°, thus
x + 4x = 180 , that is
5x = 180 ( divide both sides by 5 )
x = 36
Thus the larger angle = 4x = 4 × 36 = 144°
Answer:
let the smaller angle be x.Then the bigger angle will be 4x.
x+4x= 180
or, 5x=180
or, x=180/5
there fore, x=36
Again,
4x=4×36
=144
The larger angle is 144.

Answers
Answer:
90 hour
Step-by-step explanation:
300 minutes is for 1 school week
so if you multiply 300 minutes for 18 weeks it results as 5400 minutes.
300 × 18 = 5400 minutes
To get the number of hours you should divide 5400 minute by 60 minutes ( which is one hour )

Amber is making a scale drawing of a movie screen. Her local theater is 60 ft wide and 200 ft tall in her scale drawing the screen has a width of 9 inches what will the height of her screen on her drawing be
Answers
Answer:
The height of her screen on her drawing must be 30 inches.
Step-by-step explanation:
The scale factor is obtained by dividing the drawn width by real width of the movie screen:
[tex]k = \frac{9\,in}{60\,ft}[/tex]
[tex]k = \frac{3\,in}{20\,ft}[/tex]
The drawn height of movie screen is the product of the scale factor and the real height of the movie screen:
[tex]h_{s} = \left(\frac{3\,in}{20\,ft} \right)\cdot (200\,ft)[/tex]
[tex]h_{s} = 30\,in[/tex]
The height of her screen on her drawing must be 30 inches.

Answers
Answer:
17.3 in
Step-by-step explanation:
Given the following :
Length of tank = 20 inches
Width of tank = 10 inches
Amount of water poured into tank = 15 gallons
Volume(V) of tank (rectangular prism)
V = Length × width × height
Height = h
1 gallon = 231 inch³
15 gallons = (231 × 15) = 3465 in³
Hence V = 3465 in³
3465in³ = 20 in × 10 in × h
3465 in³ = 200h
h = 3465 / 200
h = 17.325 in
Height = 17.3 in ( nearest tenth)
