The answer is c. we add 4x^4+x^4. then cancel the -x^2+x^2 and also the -x and x . so, we are left with the -1. that's why the answer is c

alexandr402 [8]
Since the ratio of red drops to yellow drops is 55:88 and you have 1515 red drops, the yellow drops needed is given as
If 55=1515
   88=?
88/55*1515=2424
therefore 2424 drops of yellow will be needed to make a shade of orange

Consider the graph of the quadratic function y = 3x2 – 3x – 6. What are the solutions of the quadratic equation 0 = 3x2 − 3x − 6
son4ous [18]
Y = 3x^2 - 3x - 6 {the x^2 (x squared) makes it a quadratic formula, and I'm assuming this is what you meant...}

This is derived from:
y = ax^2 + bx + c

So, by using the 'sum and product' rule:

a × c = 3 × (-6) = -18

b = -3

Now, we find the 'sum' and the 'product' of these two numbers, where b is the 'sum' and a × c is the 'product':

The two numbers are: -6 and 3

Proof:

-6 × 3 = -18 {product}

-6 + 3 = -3 {sum}

Now, since a > 1, we divide a from the results

-6/a = -6/3 = -2

3/a = 3/3 = 1

We then implement these numbers into our equation:

(x - 2) × (x + 1) = 0 {derived from 3x^2 - 3x - 6 = 0}

To find x, we make x the subject of 0:

x - 2 = 0

OR

x + 1 = 0

Therefore:

x = 2

OR

x = -1

So the x-intercepts of the quadratic formula (or solutions to equation 3x^2 - 3x -6 = 0, to put it into your words) are 2 and -1.


We can check this by substituting the values for x:

Let's start with x = 2:

y = 3(2)^2 - 3(2) - 6
= 3(4) - 6 - 6
= 12 - 6 - 6
= 0 {so when x = 2, y = 0, which is correct}

For when x = -1:

y = 3(-1)^2 - 3(-1) - 6
= 3(1) + 3 - 6
= 3 + 3 - 6
= 0 {so when x = -1, y = 0, which is correct}

If (x + 8) is a factor of f(x), which of the following must be true?
ankoles [38]

Answer:

x = -8 is a root.

f(-8) = 0 is correct.

Step-by-step explanation:

As

(x + 8) is a factor of f(x)

then it must be

x = -8 is a root.

Therefore,

f(-8) = 0 is correct.

the sum of the ages of josh and autumn is 88 years 9 years ago josh was 4 times autumn age how old is josh now
forsale [732]
Let
x---------> <span> josh"age
y--------> </span><span>autumn' age

we know that
x+y=88--------> y=88-x---------> equation 1
(x-9)=4*(y-9)--------> equation 2

substitute equation 1 in equation 2
(x-9)=4*(88-x-9)
x-9=4*(79-x)
x-9=316-4x
x+4x=316+9
5x=325
x=65

the answer is
</span>josh"age is 65 years
