find 2 consecutive integers whose sum is -97
Answer:
The first integer is: -49
The second integer: -49+1 = -48
Solution Check:
-49+(-48) = -97
Step-by-step explanation:
Let the first integer: [tex]x[/tex]
As we are looking for a consecutive integer, so
The second integer would be: [tex]x+1[/tex]
We know the sum of these two integers is -97. Thus, we can write this equation and solve for 'x'.
[tex]x+\left(x+1\right)=-97[/tex]
[tex]x+x+1=-97[/tex]
[tex]2x+1=-97[/tex]
[tex]2x=-98[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{-98}{2}[/tex]
[tex]x=-49[/tex]
Therefore,
The first integer is: -49
The second integer: -49+1 = -48
Solution Check:
-49+(-48) = -97

A bee flies at 15 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 14 minutes, and then flies directly back to the hive at 9 feet per second. It is away from the hive for a total of 16 minutes. A. What equation can you use to find the distance of the flowerbed from the hive? B. How far is the flowerbed from the hive?
9514 1404 393
Answer:
A) d/900 +14 +d/540 = 16
B) 675 feet
Step-by-step explanation:
A) The times are all given in minutes, so it is convenient to use units of feet and minutes in this problem. There are 60 seconds in a minute, so the bee's speeds can be rewritten as ...
15 ft/s = (15 ft/s)(60 s/min) = 900 ft/min
9 ft/s = (9 ft/s)(60 s/min) = 540 ft/min
We know that time is the ratio of distance to speed, so for distance d, we have a total time of ...
d/900 +14 +d/540 = 16
B) To solve the equation, we can subtract 14, then combine the fractions. Here, we choose to combine the fractions in a straightforward way, not being too concerned about "least common denominator." We use the formula ...
a/b + c/d = (ad +bc)/(bd)
(540d +900d)/(900·540) = 2 . . . . subtract 14, combine fractions
d = 2(900)(540)/(1440) = 675
The flowerbed is 675 feet from the hive.
Rewrite the quadratic expression in vertex form by completing the square. You must show all work.
y = (x^2)-2x + 7
Answer:
[tex]f(x)=(x-1)^{2}+6[/tex]
Step-by-step explanation:
First, subtract 7 from each side.
[tex]-7=x^{2} -2x[/tex]
Now, add in a blank on each side so you can write in your new term that will complete the square. We'll call that term 's' for now.
[tex]-7+s=x^{2} -2x+ s[/tex]
The next step is to take half of the b term, and then square that. In this case, half of '[tex]-2[/tex]' is [tex]-1[/tex]. If we square that we get [tex]1[/tex]. So that is the term we will put in for [tex]s[/tex].
[tex]-7+1=x^{2} -2x+1[/tex]
Simplify:
[tex]-6=x^{2} -2x+1[/tex]
If you look at the right side of the equation, we can factor. That's because we completed the square. We can use the 'guess and check' method to factor. Remember, this is where we use 2 sets of parentheses and fill in the blanks.
[tex]-6=(x-1)(x-1)[/tex]
If we were to FOIL the right side we would end up with [tex]x^{2} -2x+1[/tex].
Since we have 2 '(x-1)' terms next to each other, we can simplify to:
[tex]-6=(x-1)^{2}[/tex]
Now, all we need to do is add 6 to both sides and we have the vertex form.
[tex]f(x)=(x-1)^{2}+6[/tex]
I hope this helps!

remainder of the shelf.
1
44 in.
Approximately how many more cups can Tony
place on the remainder of the shelf?
11
19
16
Answer:
C. 16
Step-by-step explanation:
If you have 44 in space and 2 cups already on there ( 4 in) you now only have, 36 in space left.
So, 16 multiplied by 2 1/4 or 2.25 in decimal is 44 in total.
Therefore you need approximately 16 more cups.

Hal owns a printing company. Last Christmas, he charged $8 for a set of 25 greeting cards and $14 for a set of 50. a. Find two ordered pairs that represent the situation. (8,25) (14,50)
Answer:
(8, 25) and (14, 50)
Step-by-step explanation:
Total cost of a set of cards = price per unit x number of cards
= p x n
Thus, the total cost of printing each set of cards depends on the price per unit and number of cards. So that it can be represented in ordered pair as: (p, n).
For the first set of greeting cards,
the cost of printing a card = $8.0
number of cards printed = 25
This can be represented in ordered pair as (8, 25)
For the second set of greeting cards,
the cost of printing a card = $14.0
number of cards printed = 50
This can be represented in ordered pair as (14, 50)
Thus, the two ordered pairs that can represent the situations are (8, 25) and (14, 50).

Joan has started a physical fitness program. One of her goals is to be able to run at least 5
miles without stopping. She can now run 3.5 miles without stopping. How many more
miles must she run non-stop to achieve her goal?
Answer:
1.5 miles
Step-by-step explanation:
Since Joan need to run 5 miles without stopping and already runs 3.5 miles without stopping, the number of miles more she must run non-stop to achieve her goal of 5 miles without stopping is the difference between her 5 mile goal and her current run of 3.5 miles.
So, number of miles she must run = 5 miles - 3.5 miles = 1.5 miles.
So, Joan must run 1.5 miles more non-stop to achieve her goal.
