Answer:

4 + (or -) 3i

Step-by-step explanation:

Hi!

Alright, so we're going to move all of the variables and constants to one side. Then, using the quadratic formula, we'll find the answer.

1. Move 12x-5 to the left side of the equation by

  a. Subtracting 12x from both sides

  b. adding 5 to both sides.

1: x^2+4x+20-12x+5

2. Group the common terms

  x^2+4x-12x+20+5 --> x^2-8x+25

3. Look at the problem. We can't factor this.

Explanation for why this isn't factorable (you can skip this)

(1) 25 is positive, so its two factors will both be either positive or negative. We're looking for a negative 8, so let's go with negative.

(2) Factors of 25: 1 & 25, 5 &5

Seeing the problem? Ya, none of the factors of 25 sum to eight. So, instead, we're going to use the quadratic formula.

4.  So, the quadratic formula: [tex]\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex]

Our equation is x^2-8x+25=0

a is the constant in front of the x^2

b is the constant in front of the x

c is the term without any x values

so, a=1, b=-8, and c= 25

Into equation:

[tex]\frac{8+-\sqrt{64-4(1)(25)} }{2a}[/tex]=[tex]\frac{8+-\sqrt{64-100} }{2}[/tex]=[tex]\frac{8+-\sqrt{-36} }{2}[/tex]

8/2 = 4

sqrt(-36) = 6i

6i/2 = 3i (remember, we still have the two in the denominator)

4 + (or -) 3i

Answer:

[tex]x=4+ 3\mathbf{i}[/tex]

[tex]x=4- 3\mathbf{i}[/tex]

Step-by-step explanation:

Solve:

[tex]x^2+4x+20=12x-5[/tex]

Move everything to the left side:

[tex]x^2+4x+20-12x+5=0[/tex]

Simplify:

[tex]x^2-8x+25=0[/tex]

Apply the solver formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Where a=1, b=-8, c=25. Thus:

[tex]\displaystyle x=\frac{8\pm \sqrt{(-8)^2-4(1)(25)}}{2*1}[/tex]

[tex]\displaystyle x=\frac{8\pm \sqrt{64-100}}{2}[/tex]

[tex]\displaystyle x=\frac{8\pm \sqrt{-36}}{2}[/tex]

The solutions are complex numbers:

[tex]\displaystyle x=\frac{8\pm 6\mathbf{i}}{2}[/tex]

Simplifying:

[tex]x=4\pm 3\mathbf{i}[/tex]

Two solutions are found:

[tex]x=4+ 3\mathbf{i}[/tex]

[tex]x=4- 3\mathbf{i}[/tex]

Answer:

1,227

Step-by-step explanation:

3,000 divided by 3 is 1,000

600 divided by 3 is 200

80 divided by 3 is 26 r2

1 + r2 =3

and 3 divided by 3 is 1

1,000 + 200 + 26 + 1 = 1,227

First of all, try to understand the questions then try to make a pair of linear equations. After that make the coefficients of x or y equal in both RFD equations by multiplying them by suitable values then add or subtract them ,in such a way which will terminate any one of the variables. Then find the value of left variable. After that just put the value you have found just now In any of the equations and you'll really get the value of the second variable too.

Step-by-step explanation:

The interval is -2 <= x <= 3 (A).

Answer:

Answer is B

Step-by-step explanation:

Remember, perpendicular lines have opposite slopes. In order to do this, you just need to flip the sign (Change it to the opposite. For example, if it is 3, it would be -3), and change the slope to its reciprocal (For example, if it is 3, it would 1/3). Finally, since the equation is y = 1/2x + 10, the slope would change to -2x... so your answer is B

Answer:

No

Step-by-step explanation:

They are not equivalent fractions

Answer:

No, they are not equivalent

Step-by-step explanation:

Answer:

I: Slope = 1

x= 5/1 or 5.00000

y= 5/-1 0r 5.00000

2: Slope = -8.000/2.000 or 4.000

x= 5/2 or 2.50000

y= 10/1 or 10.00000

Answer:

7:10-7:15

Step-by-step explanation:

tim walks 80 meters per minute and 4kg is 4000.00 meter so now we know that we divided 4000.00 and 80 we get 50 now we take the time his school start subtract 50 minutes so 8:00 ( the time he supposed to be at school) subract 50 minutes that 7:10. Hoped that helped :)

Answer:

8 hours

Step-by-step explanation:

Given that:

Money spent by Jacqueline to rent a bicycle = $33.50

Per hour charges for the bicycle for renting the bicycle = $4

Processing fee charged for renting the bicycle = $1.50

To find:

The number of hours, [tex]x[/tex] for which Jacqueline rented the bicycle.

Solution:

Charges for 1 hour = $4

Charges for [tex]x[/tex] hours = $[tex]4x[/tex]

Processing fee = $1.50

Total fee charged for renting the bicycle is nothing but the sum of processing fee and the charges for [tex]x[/tex] hours charged by the bike rental facility.

Total money spent = Processing Fee + Charges for [tex]x[/tex] hours

Total money spent = 1.50 + 4[tex]x[/tex] = 33.50

[tex]\Rightarrow 4x = 32\\\Rightarrow x = \bold{8\ hours}[/tex]

So, Jacqueline rented the bicycle for 8 hours.

Answer:

50% off of the $62 for christmas wrapping is the better deal

Step-by-step explanation:

Let us compare the prices after the discount

25% off of the $40 for christmas wrapping paper

=25/100*40

=0.25*40

=$10

The new price is

40-10=$30

50% off of the $62 for christmas wrapping

50/100*62

0.5*62

=$31

The new price is

=62-31

=$31

Answer:

97

Step-by-step explanation:

13,16,19,...,301

a=13

d=16-13=3

l=a+(n-1)d

301=13+(n-1)3

301-13=(n-1)3

(n-1)3=288

n-1=288/3=96

n=96+1=97

Answer:

92

Step-by-step explanation:

Answer:

0.09x +10 is the first choice

0.07x +16 is the second choice (set the two data plans equal to each other)

0.09x +10 = 0.07x +16  (subtract 0.07x from both sides)

0.02x +10 = 16 (subtract 10 from both sides)

0.02x = 6  (divide both sides b 0.02 to isolate x)

x= 300 MB of data (the answer)
