Answer:

both (x - 5) and (x - 3) are factors of x^2  - 2x + 15

Step-by-step explanation:

Please write this all on one line:  x^2  - 2x + 15.

Recognize that 3*5 = 15.  Possible factors of x^2  - 2x + 15 are thus (x - 5) and (x + 3).  Multiplying these together results in x^2  - 2x + 15, so we have verified that both (x - 5) and (x - 3) are factors of x^2  - 2x + 15.

f(x) = x² - 2x + 15

This function f(x) will have the negative "discriminant" in root ; thus forming complex roots

So this function has no rational roots

Answer:

2 x 10^5

200,000 / 10 = 20,000

20,000 / 10 = 2,000

2,000 / 10 = 200

200 / 10 = 20

20 / 10 = 2

I divided 200,000 by 10 five times to get a number less than 10.

So, 5 is going to be the exponent.

Question Explanation:

In other words you can write 200,00 using a whole number and a power 10 using scientific notation!

In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.

Solution:

200,000 / 10 = 20,000

20,000 / 10 = 2,000

2,000 / 10 = 200

200 / 10 = 20

20 / 10 = 2

I divided 200,000 by 10 five times to get a number less than 10.

So, 5 is going to be the exponent.

5 × 10²

Step-by-step explanation:

2 × 10^-3/4 ×10^-6

= 2/4 × 10^-3 - -6

= 1/2 (10^-3 + 6)

= 1/2 ×(10^3)

= 0.5 × 10^3

= 500

= 5 × 10²

Answer:

Divide the number by 100

So if we want to find 30% of 60 we divide 60 by 100 to get 1%

60/00 = .6

.6 x 30 = 18

So 30% of 60 is 18

Answer:

$1300

Step-by-step explanation:

52/5 = 10.4

$125 * 10.4 = $1300

or another way

125/5 = $25/week

$25 week * 52 weeks = $1300

Answer:

x=32

Step-by-step explanation:

sum of interior angles of a triangle = 180

add up all angles and equate to 180

(4x-13)+(x+18)+15=180

5x=160

x=160/5=32

x+18  =   32+18    = 50

4x-13  =  4x32-13 = 128-13 = 115

add up all to check whether ans = 180;  15+50+115=180

step 1 solve for x step 2 after getting the value of x ,substitute and get the value of angles

Answer:

-9x^2 + 12x + 5

Step-by-step explanation:

I'm assuming you meant (3x – 2)^2.  The " ^ " indicates exponentiation and is required.  We then have:

9 - (3x – 2)^2, which, when expanded, is

9 - (9x^2 -12x + 4), or:

-9x^2 + 12x + 5

Answer:

3.27

Step-by-step explanation:

Let us assume that the values are the side of a right triangle where;

Hypotenuse = 6 (longest)

Angle of elevation = 33 degrees

Required

x = opposite side

Using the trig identity

Sin theta = opp/hyp

Sin 33 = x/6

x = 6sin33

x = 6(0.5446)

x = 3.27

Hence the value of x is 3.27

Note that the values of the sides are assumed.

Answer:

180

Step-by-step explanation:

40% are not 6th graders

10% of 450 if 45

there are four 10 percents in 40%, so 45 x 4 = 180

Answer:

33%

Step-by-step explanation:

To start take the original price and divide it by the new sale price.  $1.20/$0.80 = 0.66666.  We can then round that answer to 0.67.  if the new price is 67% of the original price we must then we know that 67% minus the 100% will give us the discount.  100% - 67% = 33%

Answer = 33%

Answer:

Step-by-step explanation:

Answer:

x = -3/7

Step-by-step explanation:

5(x + 3) = -2(x - 6)

Multiply the values on the outside of the parenthesis by what is on the inside.

5x + 15 = -2x + 12

Combine like terms by bringing them over to the other side using the necessary operation (addition or subtraction).

Bring -2x over to the left side by adding it to 5x.

5x + 2x = 7x

Bring 15 over to the right side by subtracting it from 12.

12 - 15 = -3

Now we have:

7x = -3

We need to get the x all by itself, so we divide both sides by 7.

7x/7 = x

-3/7 cannot be simplified further, so it is left as -3/7.
