The solution to the given equation in the real number system is x = 2 or x = -4 or x = -3/2

A real number system comprises rational numbers, irrational numbers, integers, and whole numbers. When solving a polynomial in a real number system, we need to first factor the polynomial by grouping;

i.e.

= 2x³ + 7x ² - 10x - 24

= 2x³ + 11x² + 12x - 4x² - 22x - 24

= x(2x² + 11x + 12) - 2(2x² + 11x + 12)

= (x - 2) (2x² + 11x + 12)

= (x - 2) (2x² + 8x + 3x + 12)

= (x - 2) (2 (x² + 4x) + 3(x + 4))

= (x - 2) (2x (x + 4) + 3(x + 4) )

= (x - 2) (x + 4) (2x + 3)

In a real number system;

x = 2 or x = -4 or x = -3/2

Answer:

Every fraction can be written as a decimal that will be either a decimal number or a decimal number

Hehe hope its helpful :-P

Answer:

see explanation

Step-by-step explanation:

f(x) = - (x + 1)(x - 3)(x + 2)

to find the zeros let f(x) = 0 , that is

- (x + 1)(x - 3)(x + 2) = 0

equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x - 3 = 0 ⇒ x = 3

x + 2 = 0 ⇒ x = - 2

the zeros are x = -1, 3 and x = - 2

to find the y- intercept let x = 0

f(0) = - (0 + 1)(0 - 3)(0 + 2) = - (1)(- 3)(2) = - (- 6) = 6

y- intercept is located at (0, 6 )

Answer:

A

Step-by-step explanation:

We are asked to find the amount of interest earned on $16,500 than $15,000 with APYs of 4.1% for a year.

We will use simple interest formula to solve our given problem.

I= prt

i= amount of interest

p=principal amount

r= interest rate in decimal form

t= time in years

4.1%=  41/100= 0.041

$16,500 times 0.041 -  $15,000 times 0.041

(16,500- 15,000) times 0.041

(1,500) times 0.041

So the answer is $61.50

Answer:

220

Step-by-step explanation:

Now, I'm not sure if 220 is correct, but I'll explain my reasoning.

We know three angles of a triangle add up to 180 degrees.

So, the smaller triangle has 70 degrees and a and b variables. By virtue, a + b + 70 = 180.

So, a + b = 110.

Likewise, when you look at the whole triangle, 70 degrees is also one of the angles while c and d are unknown.

So, c + d + 70 = 180.

This means c + d = 110.

So, (a + b ) + (c + d ) =

110 + 110 =

220 degrees.

I hope this helps!

Answer:

110

Step-by-step explanation:

a + b + c + d = 110

Triangle will always equal 180 degrees triangle = 180

180 - 70 = 110

The value of the expression 2C+3B is 5m + 7

The given parameters are:

C = m + 1

B = m + 5

To evaluate the expression 2C+3B;

We substitute C = m + 1 and B = m + 5

So, we have:

2C+3B = 2 * (m + 1) + 3 * (m + 5)

Expand

2C+3B = 2m + 2 + 3m + 15

Evaluate the like terms

2C+3B = 5m + 7

Hence, the value of the expression 2C+3B is 5m + 7

The equation of the parabola in standard form whose focus is (2, 5) and directrix is y = 3 is equal to the quadratic equation y = 0.25 · x² - x + 5. (Correct answer: C)

Since the directrix is a horizontal line, then we have a parabola with a vertical axis of symmetry. The standard equation of the parabola is described below:

y - k = [1/(4 · p)] · (x - h)²     (1)

Where:

By analytical geometry we understand that the least distance between the focus and the directrix is twice as the distance between the vertex and the focus. First, we find the coordinates of the vertex:

V(x, y) = 0.5 · F(x, y) + 0.5 · D(x, y)

V(x, y) = 0.5 · (2, 5) + 0.5 · (2, 3)

V(x, y) = (1, 2.5) + (1, 1.5)

V(x, y) = (2, 4)

By Pythagorean theorem we find that the distance between vertex and focus is 1. Then, the equation of the parabola in standard form is:

y - 4 = 0.25 · (x - 2)²

y - 4 = 0.25 · (x² - 4 · x + 4)

y - 4 = 0.25 · x² - x + 1

y = 0.25 · x² - x + 5

The equation of the parabola in standard form whose focus is (2, 5) and directrix is y = 3 is equal to the quadratic equation y = 0.25 · x² - x + 5. (Correct answer: C)

The graphs with no solutions are the ones with no intercepts between the curves. These are the first one and the last one.

If we have an equation like:

f(x) = g(x).

One way of finding the solutions is to graph:

y = f(x) and y = g(x) and see where the two curves intercept.

From that, the graphs where the curves do not intercept are the graphs that indicate that the equations have no solutions.

The two graphs with no intercepts are the first one (top left) and the last one (bottom right), so these are the correct options.

Based on the information above, the car with 1,000 pounds more will only go 1,194 miles, and the one with 2,000 pounds more will only go 1,188 miles.

MPG stands for miles per gallon, and refers to the distance in miles a vehicle travels for each gallon of fuel in its tank.

In general, a car consumes about 1,200 miles per gallon. However, when you add load to it, its fuel consumption is higher because it requires more force to move.

Additionally, some studies state that for every 1,000 pounds of weight added to the car, it will yield 0.5% less. So if the car has 1,000 more pounds, it's not going to go 1,200 miles per gallon, it's going to go 1,194 miles.

On the other hand, if 2,000 pounds of weight were added, the fuel economy would be 1% less, that is, it would travel 1,188 miles per gallon.
