Answer:

-7

Step-by-step explanation:

Answer: No real number solutions

The complex number solutions are [tex]x = \frac{-1+ i\sqrt{11}}{3} \ \text{ or } \ x = \frac{-1- i\sqrt{11}}{3}\\\\[/tex]

where [tex]i = \sqrt{-1}[/tex]

=======================================================

Explanation:

The given equation 3x^2+2x+4 = 0 is in the form ax^2 + bx + c = 0

We have

Let's compute the discriminant.

d = b^2 - 4ac

d = (2)^2-4(3)(4)

d = -44

The result is negative, so there are no real number solutions.

----------------

If you wanted to find the complex valued solutions, then we apply the quadratic formula.

Plug in a = 3, b = 2, c = 4

[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(2)\pm\sqrt{(2)^2-4(3)(4)}}{2(3)}\\\\x = \frac{-2\pm\sqrt{-44}}{6}\\\\x = \frac{-2\pm\sqrt{-1*4*11}}{6}\\\\x = \frac{-2\pm\sqrt{-1}*\sqrt{4}*\sqrt{11}}{6}\\\\[/tex]

[tex]x = \frac{-2\pm i*2*\sqrt{11}}{6}\\\\x = \frac{-2\pm2i\sqrt{11}}{6}\\\\x = \frac{2(-1\pm i\sqrt{11})}{6}\\\\x = \frac{-1\pm i\sqrt{11}}{3}\\\\x = \frac{-1+ i\sqrt{11}}{3} \ \text{ or } \ x = \frac{-1- i\sqrt{11}}{3}\\\\[/tex]

Notice in step 3 we have -44 under the square root. The negative value in the square root leads directly to the imaginary number [tex]i = \sqrt{-1}[/tex]

Though the term "imaginary" is a bit unfair and misleading because numbers like -22 are just as imaginary and made up by humans. It just depends on context in which imaginary numbers are useful (eg: with physics or engineering).

Answer:

x-375

Step-by-step explanation:

First, we find a fourth of $1500.

1/4*1500=375

Then we know that you need to pay $375. We will represent the money right before you pay as x, or any variable you choose.

= x-375

Answer:

16 hours

Step-by-step explanation:

148 - 68 = 80

80 / 5 = 16

Answer:

a) 4x

b) 2 + 4y

Step-by-step explanation:

a) 7x - 6x + 3x

To do this, we just need to collect the terms together. They are all coefficients of x, so all we need to do is add the number together.

7 - 6 + 3 = 4

7x - 6x + 3x = 4x

b) 2(1 + 2y)

Here we need to expand the brackets. 2 is shown to be multiplied by 1 +2y:

2(1 + 2y)

= 2*1 + 2*2y

= 2 + 4y

I hope this helps :)

Answer:

x=-3

Step-by-step explanation:

there are three x's and five one's so the equation is 3x+5

on the other side there are 2 negative x's and 10 negative one's so the equation is -2x-10

set them equal to each other

3x+5=-2x-10

5x=-15

x=-3

Answer:

Domain: (-∞, -5) (-1, ∞)

Step-by-step explanation:

Note:

For f(x) > 0: See the points of x for which the graph of f(x) lies above the x-axis.

For f(x) < 0: See the points of x for which the graph of f(x) lies below the x-axis.

We need to find the domain of f(x) for which f(x) < 0

From the graph, we can tell:

f(x) < 0 on (-∞, -5) ∪ (-1, ∞)

Therefore: The domain on which the given graph f(x) is negative, is (-∞, -5) ∪ (-1, ∞)

(4x+5) miles..........1 hour

    x    miles .........(x-1) hour

(4x+5) * (x-1) = 1 * x

in (x - 1)h = x / (4x+5)  miles

Answer:

A unit is a measure of ratio between two quantities. In this instance, the unit is a pound. The ratio you need to take is the price of each fruit and divide it by the number of pounds each fruit has to get a price per pound. See below for solution.

Step-by-step explanation:

A. 4.19 dollars / 2.5 pounds = 1.676 dollars / pound

B. 5.49 dollars / 4 pounds = 1.3725 dollars / pound

C. 6.99 dollars / 5 pounds = 1.398 dollars / pound

D. 9.59 dollars / 6.5 pounds = 1.475 dollars / pound

The lowest is B, the apples.

Answer:

If AB crosses at a right angle, it is called the "perpendicular bisector" of PQ. If it crosses at any other angle it is simply called a bisector. Drag the points A or B and see both types. For obvious reasons, the point F is called the midpoint of the line PQ. See also Angle bisector.

Answer:

1/6

Multiply 5/12 x 2/5 then cross cancel 12 and 2 and get 6 then cross cancel 5 and 5 to get 1.

Final answer:

1/6

Answer:

x = 10

Step-by-step explanation:

Y = x-5 has a slope of 1

3y - 6x = 0 is a clear linear equation with a Y-intercept of 0

y = -5 has no slope

x = 10 is a line going straight up and intersects the point (10, 0)

Which is an undefined slope

Answer:

f [ x ] = [ x - 3] [ x + 8 ] = x^2 + 5x - 24

Step-by-step explanation:

f (x)=[ x - 3] [ x + 8 ]

x [ x + 8 ] -3[ x + 8 ]

x^2 + 8x - 3x - 24

x^2 + 5x - 24

Answer:

The coordinates (12,7) would NOT be a solution to the system of linear inequalities shown below.

Step-by-step explanation:

If you do the graphing and you look at all your options of coordinates, (12,7) is the only one that is not in the shaded areas or in the lines of the inequalities. Therefore, (12,7) should be the answer to that question. :)

Answer:

the variable

Step-by-step explanation:

Given expression:

[tex](6x+9)^2-5[/tex]

When evaluating the expression for [tex]x=1[/tex], we need substitute 1 for the variable ([tex]x[/tex]) in the expression.

Evaluating the expression for [tex]x=1[/tex]:

[tex]\implies (6\cdot1+9)^2-5[/tex]

[tex]\implies (6+9)^2-5[/tex]

[tex]\implies (15)^2-5[/tex]

[tex]\implies 225-5[/tex]

[tex]\implies 220[/tex]

Answer:

Variable

Step-by-step explanation:

Let's find the value

[tex]\\ \rm\Rrightarrow (6x+9)^2-5[/tex]

[tex]\\ \rm\Rrightarrow (6+9)^2-5[/tex]

[tex]\\ \rm\Rrightarrow 14^2-5[/tex]

[tex]\\ \rm\Rrightarrow 196-5[/tex]

[tex]\\ \rm\Rrightarrow 191[/tex]

What is below the question is what I mean.

Answer:

C

Step-by-step explanation:

The reason it is C is mainly because it is the only line with a negative slope. A negative slope this direct \. It is not A because that is a positive slope (/). It is not B because that line is undefined which means it would look like this x = 2. And D is wrong because that is a zero slope line which looks like this y = 5. So it is C.

8 unit difference x, stays the same on y

Step-by-step explanation:

5 to -3 = 8 units

Answer:

x = 9

Step-by-step explanation:

Isosceles means that the two sides equal each other

As such, to find the value of x we must equal the two expressions together and isolate the variable

20 = 3x - 7

add 7 to both sides

27 = 3x

divide both sides by 3

9 = x

Answer:

The variable x equals 9.

Step-by-step explanation:

3x - 7 = 20

3x = 27

X = 9
