(x+3)^2 = x^2-3(1-x)

Answers

Answer 1

(x+3)(x+3) = x^2 -3 + 3x
x^2 + 3x + 3x + 9 = x^2 + 3x - 3
x^2 + 6x + 9 = x^2 + 3x - 3
6x + 9 = 3x - 3
3x + 9 = -3
3x = -12
x = -4

Check:
(-4+3)^2 = (-4)^2 - 3(1+4)
(-1)^2 = 16 - 3(5)
1 = 16-15
1 = 1 :)

Sally puts $2,500 in a bank account. She takes it out 10 years later and with interest, now has $4,100. What is the percent change?

Answers

Answer:

64%

Step-by-step explanation:

Find the percent change by finding the difference between the amounts, then dividing it by the original amount

(4,100 - 2,500) / 2,500

1600 / 2500

= 0.64

So, the percent change is 64%

Rewrite the function f(x)=4(x-2)²-8 in the form f(x)=ax²+bx+c.

Answers

Answer:

4[tex]x^{2}[/tex]-16x+8

Step-by-step explanation:

4(x - 2)(x - 2) - 8 = 4([tex]x^{2}[/tex] - 4x + 4) - 8 = 4[tex]x^{2}[/tex] - 16x + 16 - 8 = 4[tex]x^{2}[/tex] - 16x + 8.

Answer:

[tex]f(x) = 4x^2 -16x + 16[/tex]

Step-by-step explanation:

f(x)=4(x-2)² Simplify.

f(x) = 4x^2 - 16x + 16

Form f(x)=ax²+bx+c.

f(x) = 4x^2 - 16x + 16

What percent of 120 is 42?
can you show your work, please

Answers

Solution for 42 is what percent of 120:

42:120*100 =

(42*100):120 =

4200:120 = 35

Now we have: 42 is what percent of 120 = 35

Question: 42 is what percent of 120?

Percentage solution with steps:

Step 1: We make the assumption that 120 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=120$100%=120.

Step 4: In the same vein, $x\%=42$x%=42.

Step 5: This gives us a pair of simple equations:

$100\%=120(1)$100%=120(1).

$x\%=42(2)$x%=42(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{120}{42}$
100%
x%=
120
42

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{42}{120}$
x%
100%=
42
120

$\Rightarrow x=35\%$⇒x=35%

Therefore, $42$42 is $35\%$35% of $120$120.

It’s 35%

42/120 = 0.35

0.35 x 100 = 35%

help pleasesolve for X i need help on how to play my trumpet can someone give me a hand Perform an online or offline search, and choose a technology firm near your location. You must then call and speak to someone from the firm's Human Resources department (preferably the HR manager) and conduct a brief (15- to 20-minute) interview with them. During the interview, you need to ask questions about the company's core functions, the different types of jobs available in the company, a list of qualities that the company expects from its employees, and so on. In other words, your questions should cover the points that the HR department would include in the company's Code of Conduct Manual. You should keep a record of all the answers and write a summary of what you have learned. Alternatively, if you do not find a technology firm near your location, or if the HR manager is unwilling to have a sit-down interview, you could find a company online and correspond with the manager through email with the help of a questionnaire.

Read the passage.My Last Roller Skating PartyIn an effort to relive the good old days of youth, my friend Tim decided to throw himself a 1980s-themed party at a roller skating rink. All my college friends were going, and we decided to dress for the theme, complete with headbands, leg warmers, blue eyeshadow, and teased hair. The night of the party, everyone looked great and we all had a good time.Then I decided to show off. About ten minutes before the party ended, I started trying moves I learned long ago when I dreamed of being an Olympic figure skater. I actually had never been good enough on the ice to get anywhere near the Olympics, but I loved skating and was pretty decent at one point. There I was at the party, spinning, twirling, and skating backward. Then I decided to bring my friend Heidi in on the fun, so I grabbed her hands and pulled her along with me as I skated backward. I was smart enough to be looking behind me to make sure I wouldnt bump into anyone, but I was not smart enough to pay attention to my balance, which I lost.I fell down onto the newly buffed rink floor. Before I knew what was happening, Heidi tripped and fell on top of me, and I heard a crack. I remember feeling the wind get knocked out of me, and then a rush of faces looking down asking if I was okay. My friend Kathleen, who was studying to be a nurse, asked questions to make sure I wasnt seriously injured, and another friend called an ambulance. Since I was not yet feeling any pain, the sheer embarrassment of the moment was my main focus.In the hospital I learned that I had broken a rib and fractured my collarbone. Kathleen had come with and assured me that I was lucky: it could have been much worse. Looking back, I have to laugh at the reaction we got from the hospital staff. Every time a new doctor or nurse walked into my room, we felt the need to explain our getups. The explanation was generally met with blank stares from people who had much more pressing concerns than what the girl in Room 3 was wearing.I went home with strict instructions to move as little as possible for the next few weeks. Lucky for me, I was on summer break so I didnt have to worry about school. Id been planning to stay in my off-campus apartment and work that summer. Instead, I took a leave of absence from my job, formed a stack of books Id been meaning to read for ages, and settled in for what would surely be some of the most boring weeks of my life. The next day, Heidi called and apologized profusely for falling on me. I thanked her but pointed out that it had been my fault that I ended up getting hurt.Even so, we all feel terrible that you ended up in the hospital at the end of a great party, Heidi said. Listen, I called a bunch of people who were there and asked if they wanted to volunteer for a meal drop-off schedule. I have your breakfast, lunch, and dinner covered for the next three weeks. I needed a moment to process what Heidi was telling me. Next to my stack of books was a stack of menus from which Id planned to order all of my food for the next few weeks. The thought of an all-fast food diet had made me a little nauseous, but I knew I wouldnt be able to cook. Now my friends were coming to my rescue.Starting the next morning, in addition to bringing amazing home-cooked meals, as well as some great take-out, my friends took turns visiting me so I didnt get lonely. Those weeks ended up flying by. Before I knew it I was up and about again.Eventually, my friends let me in on what a good laugh they had the night of the party once they knew I was going to be all right, of course. As soon as my rib and collarbone healed I had a pretty good laugh about it, too. I didnt mind that they had laughed. I decided that any group of friends willing to cook for me during summer break was allowed to laugh at me.Which excerpt from the story supports the conclusion that the narrator is humble? . . .
