Kira wants to graph y = -3(x + 1)(x - 3). They think that it will be a
downward-opening parabola. They think that it has x-intercepts at (1, 0)
and (-3, O). They think that the axis of symmetry, or x-coordinate of the
vertex, will be halfway between 1 and -3, or -1. They substitute that into
their function, and get a y-coordinate of O. So, they graph their work, and
get what is shown. Explain whether you agree or disagree with Kira's work,
and if you disagree, what you think should be done differently. Answer
specifically about x-intercepts, the midpoint and axis of symmetry, and
vertex of the graph.
Answer:
it would be upward not downward
Step-by-step explanation:

Pam is making a border around her garden. She buys 9 bricks for her border. The bricks weigh 27 kilograms in all.
Answer:
Each brick weighs 3 kilograms.
Step-by-step explanation:
In order to find the weight per brick, we simply need to divide 27 by 9.
27 ÷ 9 = 3
Therefore, each brick weighs 3 kilograms.
Hope this helps! :D
Answer:
if you are looking for the weight for all of the bricks together then
the 9 bricks = 27 kilograms
so 27 ÷ 9 = 3
3 kilograms per brick
1 kilogram = 1000 grams
3 × 1000 = 3000
Each brick weighs 3000 grams.
Step-by-step explanation:

A sequence is defined by the recursive function f(n + 1) = one-halff(n). If f(3) = 9 , what is f(1) ? 1 3 27 81
Answer:
81
Step-by-step explanation:
The value of f(1) for the recursive function is (d) 81
The recursive function is given as:
[tex]f(n + 1) = \frac 13f(n)[/tex]
Multiply both sides of the equation by 3
[tex]3f(n + 1) = f(n)[/tex]
Rewrite as:
[tex]f(n) = 3f(n + 1)[/tex]
Set n = 2;
[tex]f(2) = 3f(2 + 1)[/tex]
[tex]f(2) = 3f(3)[/tex]
Set n = 1 in [tex]f(n) = 3f(n + 1)[/tex]
[tex]f(1) = 3f(1 + 1)[/tex]
[tex]f(1) = 3f(2)[/tex]
Substitute [tex]f(2) = 3f(3)[/tex]
[tex]f(1) = 3 \times 3f(3)[/tex]
[tex]f(1) = 9f(3)[/tex]
Substitute 9 for f(3)
[tex]f(1) = 9 \times 9[/tex]
[tex]f(1) = 81[/tex]
Hence, the value of f(1) for the recursive function is (d) 81

PLZZZ HELPPP Read the excerpt from "The New Marvel in Photography" by H. J. W. Dam.
In all the history of scientific discovery there has never been, perhaps, so general, rapid, and dramatic an effect wrought on the scientific centres of Europe as has followed, in the past four weeks, upon an announcement made to the Würzburg Physico-Medical Society, at their December meeting, by Professor William Konrad Röntgen, professor of physics at the Royal University of Würzburg. The first news which reached London was by telegraph from Vienna to the effect that a Professor Röntgen, until then the possessor of only a local fame in the town mentioned, had discovered a new kind of light, which penetrated and photographed through everything. This news was received with a mild interest, some amusement, and much incredulity; and a week passed. Then, by mail and telegraph, came daily clear indications of the stir which the discovery was making in all the great line of universities between Vienna and Berlin. Then Röntgen's own report arrived, so cool, so business-like, and so truly scientific in character, that it left no doubt either of the truth or of the great importance of the preceding reports. . . .
Exactly what kind of a force Professor Röntgen has discovered he does not know. As will be seen below, he declines to call it a new kind of light, or a new form of electricity. He has given it the name of the X rays.

25 = 10 + 10 + 5
If 10 = $2.00,
20 = $4.00.
10 / 2 = 5,
and $2.00 / 2 = $1.00
$4.00 + $1.00 = $5.00

Answer:
The answer is 1.
Step-by-step explanation:
9 times 7 equals 63. 6 times 7 equals 42. 3 times 7 equals 21.
63 take away 42 is 21.
21 divided by 21 is 1!
Answer:

Mrs. Storz can ride her bike 6000 meters in 15 minutes. How far can she ride in 2 minutes?
Answer:
Mrs.Storz can ride her bike 800 meters in 2 minutes.
Step-by-step explanation:
So first we have to find the unit rate of this problem. We can do that by dividing. 6000 divided by 15 is 400. So the unit rate is 1 minute / 400 meters.
Now we multiply 400 by 2 and we get 800.
if you want to check ur answer, divide 6000 by 800. You get 7.5. Divided 15 by 2, you get 7.5 That proves they are equivalent.
So Mrs.Storz can ride her bike 800 meters in 2 minutes.

The first company charges $3.50 per cubic foot of rock and $80 for delivery. The second company charges $2.50 per cubic foot of rock and $120 for delivery. Which system of equations can be used to determine the value of the width, x, at which the cost of the two companies, y, is the same?
Answer:
x = 40
Step-by-step explanation:
First company:
Charges = per cubic foot of rock fee + delivery fee
y = $3.50x + $80
Second company:
Charges = per cubic foot of rock fee + delivery fee
y = $2.50x + $120
Equate the charges of both companies
$3.50x + $80 = $2.50x + $120
3.50x - 2.50x = 120 - 80
x = 40
The cost of the two companies, y are equal when x = 40

Cell phone Plan B costs $50 per month but does not come with a phone. If you choose this plan, you will need to purchase a phone for $500. Let x = the number of months and y = the total cost of the cell phone plan. Write an equation to represent the cost of Cell phone Plan B. *
Given:
Cell phone Plan B costs $50 per month.
Cost of phone = $500
To find:
An equation to represent the cost of Cell phone Plan B. *
Solution:
We have,
Cost of phone = $500
Cost of cell phone Plan B for one month = $50
Let x be the number of months and y be the total cost of the cell phone plan.
Cost of cell phone Plan B for x months = $50x
Now,
Total cost of Cell phone Plan B = Cost of phone + Cost of cell phone Plan B for x months
[tex]y=500+50x[/tex]
Therefore, the required equation is [tex]y=500+50x[/tex].
The amount of money in a saving account after t years is represented by the function f(t) = 650(1.027)
What does the value 650 represent in this situation?
The amount of money in the savings account increases by $650 each year.
The amount of money in the savings account is 650 times the amount of the previous year.
The amount of money in the savings account decreases by $650 each year.
The initial amount in the account is $650.
Answer: The initial amount in the account is $650.
Step-by-step explanation:
The formula for compound interest is:
Future value = P * (1 + i)^t
Where,
P = Initial amount
i is the interest rate
t is the time period
The equation in the question takes the same format which means that the $600 is the initial amount in the account. It will then be compounded by the interest rate in the brackets over the amount of years the cash will be in that savings account.
