what do i subtract with a positive number to produce a negative number?

The factoring of the expression 2 x²+x=3 is (x-1) (2x+3)

By ordering the values, we get:

2x² + x - 3 = 0

To solve this exercise, we have to follow the rules of factoring:

1. Factor 1 from 1x:

2x² + x - 3 = 0

2x²  + (-2 + 3) x -3 = 0

2. Apply the distributive property:

2x² - 2x + 3x - 3 = 0

3. Groups the first two terms and the last two terms:

(2x² - 2x) + 3x - 3 = 0

4. Factorize the greatest common denominator (GCM) of each group:

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

5. Simplify the common term (x - 1) with the distributive property:

(x-1) (2x+3)

Is a technique that consist of decomposition of a factor into a product of another factor, which when multiplied together give the original number.

Answer:

Okay? whats the question

Step-by-step explanation:

Answer:

y=x+6

Step-by-step explanation:

The gradient of the line is change in y/ change in x

Thus meaning the gradient is 1. (defined as x)

The line crosses through the y-axis on the point (0,6)

So your euqation will be y = (1 - the gradient) x + (interception of y-axis) 6

Answer:

y = x + 6

Step-by-step explanation:

The general form of an equation of a line is

y= mx+b

y = slope ·x + y-intercept

Find the slope of the line, m:

-Pick any 2 points on the line, for example lets pick the points (0, 6) and (3, 10)

-Start at any of the points and go towards the other while note the path

start at (0, 6) and to go to (4, 10) we have to

go up (rise) 4 units  from 6 to 10 and

go to the right (run) 4 from 0 to 4.

Slope = m = rise/run = 4/4 = 1

m = 1

Find the y-intercept, b:

The y-intercept is where the line intersects the y-axis. By looking at the given graph we can see y-intercept is 6.

b = 6

The equation of our line is

y = x + 6

1. Carla Sanborn was born on July 12, 1936.

On October 25, 1977, She bought $30,000 worth of ordinary  life insurance on August 25, 2020.

Now, firstly we have to find her age for insurance purpose and secondly her annual premium.

Since, The age for her insurance purposes will be calculated by the nearest birthday year.

So,

July 12 ,1989 - October 25, 2020 = 31 years.

Hence, She is 31 years of age.

Now, For Her annual premium we divide what she purchased with her age as,

$30,000/31 = $ 967.74

Which is approximately be $968.

2. Bruce Lovegren was born on September 27, 1950.

On April 27, 1977, he purchased a $15,000 ten-year term life insurance     policy.

The decay factor for the annual rate of change of -0.1 % is 0.999.

A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.

With the function displayed to the right, you may represent exponential growth or decay.

A(x) = a( 1 + r)ˣ

Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.

Now, we have the annual rate of change as:

r = - 0.1 % = - 0.1 / 100 = - 0.001

From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.

So, let B = 1 + r

B = 1 + r

B = 1 + (- 0.001)

B = 1 - 0.001

B = 0.999

Now, the value of B is less than 1 therefore, the corresponding decay factor is 0.999.

Percentages are evaluated values that say how much of a whole is occupied by that value. For example, if we were to say 75% of a strawberry pie remained, we could also see this as 3/4, or three-fourths.

To solve this particular problem, we will need to divide two values and convert a decimal to a percentage.

First, set up the fraction of economics majors that are freshman students to the total number of freshman students.

[tex]\displaystyle \frac{1634}{8600}[/tex]

Then, divide the two using a calculator or long division.

[tex]\displaystyle \frac{19}{100}[/tex]

Finally, to convert this to a decimal, use a calculator.

[tex]0.19[/tex]

To convert a decimal to a percentage, multiply the decimal by 100.

Here, we are given that a homeowner is digging a 3 -ft-deep trench around the perimeter of his property.

Length of the property = 210 feet

Breadth of the property = 180 feet

Let us now consider one side of the 180-foot-long trench.

There are two such trenches, each with a width of 4 feet and a height of 3 feet.

Thus the volume of the trench = 2(length × breadth × height)

Volume = 180 × 4 × 3 × 2

= 4320 cubic feet

Now we are left with two other sides of the trench with the following dimensions-

Height = 3ft

Breadth = 4ft

Length = 210 - 8 = 202ft

Answer: (Looking back, I may have gotten this question wrong, but if I haven't then nice.)

a) 13 degrees

b) acute angle

Step-by-step explanation:

Given that we know a triangle is 180 degrees. Lets recall what an obtuse, acute, right and reflex angle are.

Obtuse: An angle greater than 90 degrees

Acute: An angle less than 90 degrees

Right: An angle that is 90 degrees

Reflex: An angle in between 180-360 degrees

Since we know that two of the three angles are 54 and 113 degrees, we can say that 54+113+x=180. That means that the missing angle, x, is 13 degrees.

Knowing that 13 is less than 90, we can also say that the third angle is an acute angle.
