I need help! what is this equation in factored form and how do you solve it using the X-method (or really any other method?)
y = -3x^2 - x + 2
Answer:
See below
Step-by-step explanation:
Part 1:
Factored: y = (-3x+2)(x+1)
Part 2:
Not exactly sure what the "x" method is after your explaination, so ill just use the quadratic formula.
Quadratic Formula:
[tex]x = \frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]
Also:
[tex]x^2=a\\x=b\\2=c[/tex]
So if you solve (not showing work):
Your x-ints are:
-1
2/3
factor the expression k^2+16k+64
Answer:
[tex]\huge\boxed{\sf (k + 8)(k + 8)}[/tex]
Step-by-step explanation:
Given expression:
[tex]k^2+16k+64[/tex]
We can write it as:
[tex]=(k)^2+2(k)(8)+(8)^2[/tex]
Using formula [tex]\bold{a^2+2ab+b^2=(a+b)^2}[/tex]
[tex]=(k+8)^2[/tex]
= (k + 8)(k + 8)
[tex]\rule[225]{225}{2}[/tex]

Use the excerpt to answer the question. As Melanie climbed down into the 2 points rowboat, Gina scooted over on the bench to make room for her. "We have to pick up Jacob now," Gina said, handing Melanie one of the oars. “And we should hurry so we can be long gone before the patrol barge comes by." Gina hadn't told Mom where she was going. Her mother had been smoothing a washcloth over Brandon's forehead as Gina had headed out. When her mother had asked where she was off to, Gina had tossed out some vague explanation. It was better for Mom not to worry. She had enough to worry about these days. They all did. Which statement conveys the main idea of the excerpt?
Gina, Melanie, and Jacob are worried to leave Brandon when they take their rowboat out because they know his mother has been fussing over him a lot lately.
Gina and Melanie need to get Jacob before they are caught, and Gina doesn't want her mother to know where she is going so as not to worry her.
Gina's mom is worrying about her and Melanie because they are going to pick up Jacob in their rowboat.
Jacob is missing, and his friends Melanie and Gina decide to go looking for him without telling anyone
Answer:
the second one
Step-by-step explanation:
Gina's mom does not know where she is, meaning that Gina did not tell her and implyling she did not want to worry her.

You add all the sides that you are given together and then you subtract that from the perimeter given. EX. In question 55 you would do 20+12=32 so 48-32=16.
Find the least common denominator (LCD) 8/9 and 4/5
Answer:
45
Step-by-step explanation:
First we write the first 10 multiples of 9 (the first denominator) :
9,18,27,36,45,54,63,72,81,90
Now we write the first 10 multiples of 5 (the second denominator) :
5,10,15,20,25,30,35,40,45,50
As we can see 45 is the lowest number that appears in both list.
Therefore 45 is the LCD of 8/9 and 4/5
Answer:
45
Step-by-step explanation:
So since we are finding the LCD, we only look at the denominators, 9 and 5.
We can count until we find the denominator:
[tex]9,18,27,36,45\\5,10,15,20,25,30,35,40,45[/tex]
So the LCD would be 45.

Pat bounced a basketball 25 times in 30 seconds. At that rate, approximately how many times will Pat bounce the ball in 150 seconds?
Answer:
125
Please mark brainliest!
Step-by-step explanation:
To get this answer, we multiply 25 by 5, because 5 = 150 divided by 30.
25 x 5 = 125, so the answer is 125.

Multiply.
12x^4 (-5/6x^3y^2)
Answer:
-10[tex]x^{7}[/tex][tex]y^{2}[/tex]
Step-by-step explanation:
12[tex]x^{4}[/tex]([tex]-\frac{5}{6} x^{3}[/tex][tex]y^{2}[/tex])
First multiply 12 * - [tex]\frac{5}{6}[/tex] , solving this you get -10
Next multiply [tex]x^{4}[/tex] by [tex]x^{3}[/tex] , solving this you get [tex]x^{7}[/tex]
Finally you have [tex]y^{2}[/tex], and nothing to multiply it by. So it stays as [tex]y^{2}[/tex]
Put is all together and you get -10[tex]x^{7}[/tex][tex]y^{2}[/tex]
-10x^7y^2

Find the nth term of this quadratic sequence. 3,11,25,45
Since you know the sequence is quadratic, we can find constants a, b, and c such that the n-th term of the sequence (denoted by f(n)) is
[tex]f(n) = an^2 + bn + c[/tex]
We're given f(1) = 3, f(2) = 11, and f(3) = 25. (We have three unknowns, so we only need three conditions.) Solve for the constants:
[tex]\begin{cases}f(1) = a + b + c = 3 \\ f(2) = 4a + 2b + c = 11 \\ f(3) = 9a + 3n + c = 25 \end{cases} \implies a=3, b=-1, c=1[/tex]
Then the n-th term of the sequence is
[tex]f(n) = \boxed{3n^2 - n + 1}[/tex]

Simplify 16 - 8 + 5x- 3x
8+8 x
10 x
8 + 2 x
16 + 2 x
Answer:
8 + 2x
Step-by-step explanation:
To simplify this expression, combine like terms.
16 - 8 = 8
5x - 3x = 2x
8 + 2x
hope this helps :)
Answer:
Because of the x between the 5 and 3 u have to put them in a bracket form or group like terms. After that u subtract the 16 from 8 and the 5x from the 3x so the answer will be equal to 8 +2x because 16-8=8 and 5x-3x=2x so it will be 8+2x

Prior to June 1, Sandler Company had no treasury stock transactions. Then, on June 1, the company paid $5,000 to purchase 100 shares of its common stock on the open market. On July 1, the company sold 50 of these shares at $52 per share. Then, on August 1, the company sold the remaining 50 shares at $46 per share. Prepare the journal entry
Answer:
Explanation:
The journal entries are shown below:
On June 1Treasury Stock A/c Dr $5,000 (50 shares × $100)
To Cash A/c $5,000
(Being treasure stock is purchased)
On July 1Cash A/c Dr $2,600 (50 shares × $52)
To Treasury Stock A/c $2,500 (50 shares × $50) To Paid in capital - Treasury stock $100(Being treasury stock is sold at higher price and the remaining amount would be credited to the paid in capital account)
On August 1Cash A/c Dr $2,300 (50 shares × $46)
Paid in capital - Treasury stock $100
Retained Earnings A/c Dr $100
To Treasury Stock A/c $2,500 (50 shares × $50)(Being treasury stock is sold at lower price and the remaining amount would be debited to the retained earning account)

Rename 5/6 and 14/15 using the least common denominator.
Answer:
[tex]\frac{25}{30}~and~\frac{28}{30}[/tex]
Multiply 5 by 5 to get your first parameter.[tex]5 * 5 = 25[/tex]
Multiply 6 by 5 to get the denominator, or your second parameter.[tex]5 * 6 = 30[/tex]
For the second fraction, [tex]\frac{14}{15}[/tex], you need to multiply both parameters by 2, similar to before, but we now must use a different number, otherwise, the denominators will not be the same.[tex]14 * 2 = 28[/tex]
Now, multiply 15 by 2[tex]15 * 2 = 30[/tex]
The last step is to put these numbers you gathered into fractions. The bigger number always goes on the bottom, referred to as the denominator, while the smaller number, referred to as the numerator, always goes on the top.[tex]25~and~30 -- > \frac{25}{30}[/tex]
[tex]28~and~30-- > \frac{28}{30}[/tex]

Endeye needs to split 1/5 of the dinner left over from last week to feed her 3 siblings. What fraction of the original dinner will each sibling have to eat tonight?
Answer:
They each had 1/20 of the original meal
Step-by-step explanation:
To begin, there are 4 people. Her siblings, and herself. She is splitting the 1/5 leftover to feed them. To do this, we simply take 1/5 and put it into a fraction to get 0.2. Next, we can put 0.2 / 4 into a calculator to get how much each person can get.
0.2 / 4 = 0.05.
Now, we need to turn it into a fraction to find out how much they had in fraction form of the original.
0.05 = 1/20
They each had 1/20 of the original meal

Mary had 12 eggs. She ate 2 eggs per day (x). Choose all of the points that would lie on a graph of the line representing the number of eggs remaining, y, after x days. O A. (2,4) B. (2,8) C. (2,10) D. (4,2) E. (4.4) G F. (4,8)
Answer:
B. (2,8)
E. (4,4)
Explanation:
equation that can be created: y = 12 - 2(x)
where y is the remaining eggs and x is days
sequence: coordinates:
1st day: 12 - 2 = 10 (1,10)
2nd day: 10 - 2 = 8 (2,8)
3rd day: 8 - 2 = 6 (3,6)
4th day: 6 - 2 = 4 (4,4)
5th day: 4 - 2 = 2 (5,2)
6th day: 2 - 2 = 0 (6,0)
