Nat2105 [25]3 years ago
4 0

5 + (16 + 2) ÷ 3 = 11

First you add 16 and 2 which is 18. Then divide 18 by 3 which is 6. Lastly, you add 6 and 5 which gives us our answer, 11.

Hope this helps

Explain whether we would rather have the solution to 3x=7 expressed as a fraction or as a repeating decimal.
PolarNik [594]

Answer:

A

Step-by-step explanation:

While fractions are more exact, it will always depend on the scenario. You aren't going to give the amount of money something is as a fraction, that will always be a decimal. However, in most math circumstances, fractions can get more straight to the point since there is no such thing as a truly repeating fraction.

See attachment for graph.

Notes: graph each line as if they are "equal".
Then draw the lines as:
dashed for < and > 
solid for ≤ and ≥
Next, choose a test point and plug it into both equations.  If the result is True for BOTH equations, then shade that section.

Phillip is standing across the classroom from his desk. He walks x steps in a straight line to his right, turns left at a 90° an
Rainbow [258]
For this case, we can model the problem as a triangle with a right angle.
 Where,
 x, y: lengths of the sides of the triangle
 d: hypotenuse of the triangle
 We then have the following relationship:
 d ^ 2 = x ^ 2 + y ^ 2&#10;
 Clearing d we have:
 d = \sqrt{ x^2 + y^2}
 Answer:

Write a polynomial function that meets the stated conditions.The zeros are −1, 2, and 7.
kondaur [170]

Answer:

A polynomial function that meet the conditions is x³ - 8x² + 5x + 14 = 0

Step-by-step explanation:

Hi there!

Let´s start writting a generic factored function. In this case, the function has 3 zeros so that the factored form will have 3 terms:

(x + a)(x + b)(x + c) = 0

For this expression to be 0, either (x+a) = 0 or (x+b) = 0 or (x+c) = 0

Then:

x + a = 0 ⇒ x = -a

x + b = 0 ⇒ x = -b

x + c = 0 ⇒ x = -c

Then, the values "a", "b" and "c" are equal to the zeros of the function but with opposite sign. Then, in our case:

a = 1

b = -2

c = -7

Then, the polynomial fuction will be:

(x + 1)(x - 2)(x - 7) = 0

Apply distributive property:

(x² - 2x + x -2)(x -7) = 0

(x² - x - 2)(x - 7)

x³ - x² - 2x - 7x² + 7x + 14 = 0

x³ - 8x² + 5x + 14 = 0

Then, a polynomial function that meets the conditions is:

x³ - 8x² + 5x + 14 = 0

Have a nice day!

PLEASE HELP.<br> What is the value of X in the photo below? (please show work)
Tom [10]

Value of x is 5. I remember doing this last year..

35a+45b=80

then we would do 99-80, and that gives us the value of c, 19
