Mathematics
1 answer:
Serhud [2]3 years ago
6 0

Answer:

1. 2x^2-15x+17=0

2. 2.4x^2-3.5x-2.2=0

3. -4.2x^2+6.8x-2=0

Step-by-step explanation:

Standard form is written as ax^2+bx+c=0. To write each equation in standard from:

  • Distribute into any parenthesis
  • Move terms across the equal sign with inverse operations
  • Combine any like terms

1.

2(x-3)^2=3x+1\\\\2(x^2-6x+9)=3x+1\\\\2x^2-12x+18=3x+1\\\\2x^2-15x+17=0

2.

2.4x^2-3.5x=2.2\\\\2.4x^2-3.5x-2.2=0

3.

6.8x - 2 = 4.2x^2\\\\-4.2x^2+6.8x-2=0

DEF is a dilation image of ABC. What is the scale factor?
horsena [70]

Answer:

Option (2)

Step-by-step explanation:

ΔDEF is a dilation image of ΔABC.

Rule for the dilation,

Scale factor = \frac{\text{Length of one side of the image triangle}}{\text{Length of one side of the original triangle}}

                    = \frac{DE}{AB}

                    = \frac{4}{8}

                    = \frac{1}{2}

Therefore, scale factor by which ΔABC is dilated is \frac{1}{2}.

Option (2) will be the correct option.

A hungry elf ate 35 of your muffins. That was 710 of all of them! With how many did you start?
KengaRu [80]

Answer:

2094.5 muffins

Step-by-step explanation:

The problem is a little bit messy, but i’m guessing you meant that the elf ate 35% of the muffins, which 35% is 710 muffins. so since 35% of muffins is 710 muffins, let’s multiply that by 2 so we can get 70%.

so 710 x 2 is 1420. so 70% of the muffins is 1420 muffins! sadly that’s not all of the muffins. we’re still missing another 30%. since we don’t know how many muffins are in 30%, let’s just take 710 muffins - 5%. when you do that you get 674.5. so now that we know how much is in 30%, let’s take 1420 + 674.5. when you do that you get 2094.5! so you started off with 2094 and a half muffins!

What is the value of the fraction below?<br> 14/0
klasskru [66]

Answer:

It isn't a number so you would call it undefined

You can think of it like 14 divided by 0 and like siri said “Imagine that you have zero cookies, and you split them evenly among zero friends. How many cookies does each person get? See? It doesn’t make sense. And Cookie Monster is sad that there are no cookies, and you are sad that you have no friends.” In this case, “Imagine that you have 14 cookies, and you split them evenly among zero friends. How many cookies does each person get? See? It doesn’t make sense. And Cookie Monster is happy he gets 14 cookies, and you are sad that you have no friends.”
