The graph shows a function of the form f(1) = ax + b.
Use the drop-down menus to complete the statements about the function, and then
write an equation that represents this function
Answer:
f(0) = -3
x increases by 1 f(x) increase by 2
f(x) = 2x -3
Step-by-step explanation:
Looking at the graph
f(0) means when x =0 the value of y = ?
when x = 0 y = -3
f(1) means when x = 1 y = ?
When x = 1 y = -1
y increased from -3 to -1 so it increased by 2
f(x) = ax+b where a is the increase and b is the value at x =0
f(x) = 2x -3
Which graph shows a method for finding the image of point D if the parallelogram is reflected across the dashed line?
Answer:
The third option with the right angle
Step-by-step explanation:
By creating a perpendicular line through the line of reflection (the orange dotted line) and the point "D" we can measure the distance of D from the line of reflection. Then draw "D'" using the distance of the "D" from the line of reflection.

which describes a greater unit rate of change of Y with respect to X the equation Y = 4.5x or the table
Answer:
The proportional relationship is same
Step-by-step explanation:
Generally, we can get the unit rate by dividing the y-value by the x-value
This will be;
9/2 or 18/4 or 27/6 = 4.5
from what we have y = 4.5x
Now, as we can see, the proportional relationship is same
Triangle DEF is simliar to triangle QRS. If side QR is 1.5 times the length of side DE, and side RS has a length of 6, what is the length of side EF? Also, there is no picture for this question.
Answer:
4
Step-by-step explanation:
the scaling factor is 1.5 to go from DEF to QRS.
so,
EF × 1.5 = RS = 6
EF = 6 / 1.5 = 6/1 / 3/2 = 6×2 / 1×3 = 12/3 = 4

Answer:
18c - 30d + 36
Step-by-step explanation:
To apply the distributive property, we must "distribute" (multiply) the outer term by the terms in the parentheses. In this case, the outer term is 6, and the inner terms are 3c, 5d, and 6. Then, if there's any like terms, you must combine them.
6(3c - 5d + 6)
(6 · 3c) + (6 · -5d) + (6 · 6)
18c + -30d + 36
As you can see, there's no like terms in this expression, so the equivalent expression to 6(3c - 5d + 6) is 18c + -30d + 36.
Let’s think about another type of scenario. What if you were told that a bracelet requires 10 beads and 10 minutes to make while a necklace requires 20 beads and takes 40 minutes to make. The craftsman has 1000 beads to work with and he has 1600 minutes in which to work. If a bracelet costs $5 and a necklace costs $7.50, what is the maximum revenue that the craftsman can take in?
Answer:
$425
Step-by-step explanation:
Let x represent the number of bracelets made and let y represent the number of necklace made.
Since the craftsman has 1000 beads to work with, hence:
10x + 20y ≤ 1000 (1)
Also, the craftsman has 1600 minutes, hence:
10x + 40y ≤ 1600 (2)
From ploting equations 1 and 2 on the geogebra online graphing, we can see that the solution to the problem is (40, 30).
Since the bracelet costs $5 and a necklace costs $7.50, hence the maximum revenue is:
Revenue = 5x + 7.5y = 5(40) + 7.5(30) = $425

The amount of money that we need to deposit in the bank to get RS 1225 is RS 1100.03.
What is compound interest?Compound interest is applicable when there will be a change in principal amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount.
Suppose we need to deposit the P amount to get RS 1225
By compound interest formula,
1125 = P(1 + 0.05)^(9/2)
P = RS 1100.03
Hence "We need to deposit Rs. 1100.03 in the bank in order to receive Rs. 1225".

SR and LN are corresponding sides.
SR and LN are equal.
The value of b is 5.
The value of SR is 43
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
△STR ≅ △LMN
This means the corresponding sides are equal.
SR = 7b + 8
LN = 11b − 12
SR and LN are corresponding sides.
SR and LN are equal.
So,
7b + 8 = 11b − 12
Subtract 7b on both sides.
8 = 11b - 7b - 12
Add 12 on both sides.
8 + 12 = 4b
20 = 4b
b = 20/4
b = 5
Now,
SR:
= 7b + 8
= 7 x 5 + 8
= 35 + 8
= 43
Thus,
The value of b is 5.
The value of SR is 43

Chamblee High School is selling Valentine's Day gifts as a fundraising event. One long stemmed rose costs $3.00 while one long stemmed carnation costs $1.50. If 50 orders
were placed and they totaled $195, how many roses and carnations were ordered?
100 roses and 100 carnations
60 roses and 10 carnations
125 roses and 75 carnations
50 roses and 145 carnations
Answer: Choice B) 60 roses and 10 carnations
============================================================
Explanation:
r = number of rosesc = number of carnationsr and c are positive whole numbers.
r+c = total number of flowers = 50, since 50 orders are made.
The first equation to set up is r+c = 50.
This equation can be solved to get r = 50-c.
------------------
3r = cost of all the roses only, in dollars
1.5c = cost of all the carnations only, in dollars
3r+1.5c = total cost of all the flowers = 195 dollars
3r+1.5c = 195
------------------
Let's apply substitution to solve
3r+1.5c = 195
3(50-c)+1.5c = 195
150-3c+1.5c = 195
-1.5c+150 = 195
-1.5c = 195-150
-1.5c = 45
c = 45/(-1.5)
c = -30
That's not good. We shouldn't get a negative value.
It turns out that the condition r+c = 50 should be ignored. Notice how none of the answer choices listed have r+c leading to 50.
So we'll only focus on the equation 3r+1.5c = 195
-----------------
If we plugged in r = 100 and c = 100, then we get
3r+1.5c = 195
3(100)+1.5(100) = 195
300+150 = 195
450 = 195
Which is false. So we can rule out choice A
Let's repeat those steps for choice B
3r+1.5c = 195
3(60)+1.5(10) = 195
180 + 15 = 195
195 = 195
So that works out. I have a feeling your teacher meant to say "70 orders" instead of "50 orders". If so, then the equation r+c = 50 would be r+c = 70 and everything would lead to choice B as the final answer.
Choices C and D are similar to that of choice A, so they can be ruled out.

What is the area of a hexagon with an apothem of 24 m?
Answer:
Area of Hexagon = 1,995 m² (Approx.)
Step-by-step explanation:
Given:
Length of apothem = 24 m
Number of total sides = 6
Find:
Area of Hexagon
Computation:
Side = a[2tan(180/n)]
Side = 24[2tan(180/6)]
Side = 24[2tan(30)]
Side = 27.71 m (Approx.)
Area of Hexagon = [3√3a²]/2
Area of Hexagon = [3(1.732)(27.71)²]/2
Area of Hexagon = [3(1.732)(767.8441)]/2
Area of Hexagon = 3989.71794 / 2
Area of Hexagon = 1994.8589
Area of Hexagon = 1,995 m² (Approx.)

45° + m∠R + 60° = 180°
m∠R = 75°

The cost of a book is $x what is the expression in terms of x for the number of these books which are bought for $40
Answer:
In x dollars,
number of book that can be bought = 1
So, In 1 dollar,
number of books that can be bought = 1/x
Hence in 40 dollars,
number of books that can be bought = 40/x
Answer:
40/x
Step-by-step explanation:
The cost of 1 book is $X.
You bought (?) books for $40.
If you want to know how many books you bought, divide the total cost of books ($40) by the cost of 1 book ($X).
a cooler has 60L capacity. its internal length is 60cm and its internal width is 35cm. Determine the internal height and the internal surface area of the cooler.
Answer:
Internal height is approximately 28.5714285714286 cm
Internal surface area is roughly 9628.57142857143 square cm
Round the values however you need to
==========================================================
Step-by-step explanation:
Work Shown:
1 L = 1000 mL
1 L = 1000 cm^3
60 L = 60,000 cm^3 (multiply both sides by 60)
The cooler has volume of 60,000 cubic cm. Let V = 60000
Assuming the cooler is a rectangular prism (aka a block), then we can say
volume = length*width*height
V = L*W*H
60000 = 60*35*H
60000 = 2100H
2100H = 60000
H = 60000/2100
H = 28.5714285714286 which is approximate
And the surface area (SA) is
SA = 2*(LW + LH + WH)
SA = 2*(60*35 + 60*28.5714285714286 + 35*28.5714285714286)
SA = 9628.57142857143 which is also approximate
Units for the surface area are in square centimeters.
