Find the area of the region bounded by the y-axis, x-axis and the line y=-2x+4.

Answers

Answer:2

Step-by-step explanation:y = 0 : 0 = -2x + 4 → x = -2 is the x-intercept. Similarly, when the line crosses the y-axis, the x-coordinate at this point will be zero and substituting x = 0 into the equation will give us the y-intercept. x = 0 : y = 0 + 4 → y = 4 is the y-intercept.

Solve the equation.
1/10 (x + 34) = −2(4 − x)
x = _____

HELPPP PLZZ DUEE TODAYY

Answers

Answer:

−0.383

Step-by-step explanation:

Let's solve your equation step-by-step.

1/10 (x+34)=(−2(4−x))(x)

Step 1: Simplify both sides of the equation.

1/10 x+ 17/5 =2x2−8x

Step 2: Subtract 2x^2-8x from both sides.

1/10 x+ 17/5 −(2x2−8x)=2x2−8x−(2x2−8x)

−2x2+ 81/10 x+17/5 =0

For this equation: a=-2, b=8.1, c=3.4

−2x2+8.1x+3.4=0

Step 3: Use quadratic formula with a=-2, b=8.1, c=3.4.

−b±√b2−4ac

−(8.1)±√(8.1)2−4(−2)(3.4)

2(−2)

−8.1±√92.81

x=−0.38344867082526823,4.433448670825268

Step 4: round to the nearest hundred

Essentially just turn the big number into an exponent so u can cancel out and be left with just the x for example 128 is the same as 2^7 and when you have it like that you simply cancel the 2 and are left with x=7

A) x=7
B) x=6

Need help with a math problem

Answers

Answer:

Step-by-step explanation:

Here's what's going on: some person buying their furniture sees this sofa and it's $1200. That person sees theres a 1/3 off sale! They're happy and buy their sofa with a 20% off discount they got.

Now we have to find out if they should use the 20% off discount before or after adding the 1/3 off sale.

The answer is, they're both the same.

Say they add the 1/3 off sale discount and then use their 20% off discount. Find the 1/3 off sale: 1200 divided by 3 (because fractions are division problems) = 400. 20% of 400: 400 x 0.2 = 80. It's not just 80, because it's not an "only pay 20%" discount. 400 - 80 = 320. They'd pay $320 with this method.

This shows that using the 20% discount after the 1/3 off sale the customer spends $320.

Now let's calculate what happens if they use the discount after the 1/3 off sale. 20% of 1200: 1200 x 0.2 = 240. 1200 - 240 = 960. Now adding the 1/3 off sale: 960 divided by 3 = 320. They'd also pay $320 with this method.

If it's a short answer, you could just write something like, "No, both methods end up with the sales associate paying $320."

Hope this helps!

Those six words have echoed throughout my house each morning ever since I could understand them."Matt, do you have your EpiPen?" "Matt, do you have your EpiPen?" "Matt, do you have your EpiPen?" How many times have I heard that? Thousands. Growing up with a food allergy was a huge burden requiring constant vigilance. Vigilance about carrying my EpiPen, where to sit at the school lunch table, who would chaperone the field trip, whose birthday party would my mom or dad have to hang out at, whose house was safe for me to hang out at, vigilance about what foods I eat.Since enrolling and subsequently graduating from a Stanford food allergy study led by Dr. Kari Nadeau, my anxiety surrounding my allergy has greatly decreased, but my vigilance remains steadfast. The Stanford study has given me safety from cross contamination and a life without fear.My EpiPen goes with me everywhere just like my shadow. Everyone with severe allergies should have this shadow with them too. My good friend (who has multiple food allergies) doesn't carry an EpiPen when he is with me. His rationale behind it is, "I'm with you, so I don't need one." I recently met someone who does not carry an EpiPen although she has a diagnosed anaphylactic allergy to tree nuts and peanuts. Her rationale? "I've never had a reaction and I am really careful about what I eat."I cannot understand when I meet people with food allergies and they do not carry an EpiPen. Sometimes they say, "I just get hives around my mouth." Or "I just get a little itchy on my tongue." Or "I have an EpiPen, it's in my car." CAN YOU BE SERIOUS?Before entering the allergy study, unfortunately for me I had to use my trusted EpiPen several times. It was very tense, scary and thankfully quick. After a person gets over the paralyzing fear of the needle (which is actually hidden inside the pen), the EpiPen is actually easy to use (once you get the hang of it). The EpiPen works so fast. It actually stops the allergic reaction in its tracks. It is the only life saving medication food allergic people can use to help prevent life threatening reactions.So yes, under the advice of my doctor, I still carry an EpiPen. In fact, my doctor recommends that anyone with a food allergy carry an EpiPen. Even though I successfully eat a lot (4,000 milligrams each) of all of my allergens daily, (which are wheat, rye, barley and oats), my EpiPen is always by my side -- at camp, tennis, school, or a party. I know the facts of how quickly a reaction can escalate, and I may still have a reaction. I am, after all, a living science experiment.The words, "Matt, do you have your EpiPen?" are still essential to my life.Do you think that the author was successful in writing a persuasive opinion piece?HELP!! 2.
