Answer:

15.5

Step-by-step explanation:

Well to start its written on your page, but i'll be of use anyways.

You are to convert 3/4 and 2/3 to make the bottom number called a denominator equal to each other. You would start by multiplying 4x3 and you get 12. now we perform something called cross multiplying. 3x3=9 so one of our fractions is to be 9/12 and we multiply 4x2 to get 8 so our other fraction is 8/12 next we simplify. After so, we add our biggest number to the mix, that number is 15. There stand your answer that can be phrased in three different ways, with the restrain of using these numbers.

The way to phrase this expression is 15.5, 15 and 6/12, 15 and 3/6

And finally the most original way, 15 and 1/2.

Hope it helped.

How can Kendra determine if the function is actually linear?

pashok25 [27]

Answer:

D. She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

Step-by-step explanation:

Find the rate of change between first two ordered pairs and the second two ordered pairs:

1. Points (2,4) and (3,9). Rate of change:

$\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-4}{3-2}=\dfrac{5}{1}=5$

2. Points (3,9) and (4,16). Rate of change:

$\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{16-9}{4-3}=\dfrac{7}{1}=7$

The rate of change for the linear function must the same for each two points on the graph of the function. In this case, the reate of change differs, so this function is not linear and correct option is D.

Please helpppppppppp

Alika [10]

Answer:

x = 1/3

Step-by-step explanation:

f(x) = -3x^2 + 2x-17

This is in the form

ax^2 +bx+c

a = -3 b = 2 c = -17

The axis of symmetry is at

x = -b/2a

x = -2/ (2*-3)

x = -2/-6

x = 1/3

Simplify completely the quantity 4 times x to the third power plus 5 times x to the 2nd power plus 3 times x all over x. (2 poin

julia-pushkina [17]

We start with

$\dfrac{4x^3+5x^2+3x}{x}$

We can factor x at the numerator:

$\dfrac{x(4x^2+5x+3)}{x}$

So, assuming $x\neq 0$ (otherwise the expression would make no sense) we can simplify it:

$\dfrac{x(4x^2+5x+3)}{x} = 4x^2+5x+3$

This equation has no roots, so we can't simplify it any further.

What is the equivalent decimal to this fraction? 10/45 0.2 0.222222222... 0.232323232323... 0.181818181818...

Ivan

Factorize the numerator and denominator, then simplify:

10/45 = (2×5)/(9×5) = 2/9

Now,

1/9 = 1/10 + 1/90

1/90 = 1/10 × 1/9 = 1/10 × (1/10 + 1/90) = 1/100 + 1/900

1/900 = 1/100 × 1/9 = 1/100 × (1/10 + 1/90) = 1/1000 + 1/9000

and so on, which is to say

1/9 = 1/10 + 1/100 + 1/1000 + …

1/9 = 0.111…

so that multiplying both sides by 2 gives

2/9 = 0.222…
