Answer:

-7, 14

Step-by-step explanation:

We start by writing this in the form $x^2 + bx + c = 0$, so we subtract 98 from both sides of the equation.

This gives us $x^2 - 7x - 98 = 0$. We proceed by factoring $x^2 - 7x - 98$, so we seek numbers that multiply to $-98$ and add to $-7$. We find that $7$ and $-14$ work.

Thus, our equation becomes $(x + 7)(x - 14) = 0$. We can now apply the fact that if the product of two real numbers is zero, then at least one of the real numbers must be 0.

Solving $x + 7 = 0$ and $x - 14 = 0$, we find that the solutions are $\boxed{x  =-7~\text{and}~x = 14}$.

The value of the equation is given by x = 14 or x = -7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

x² - 7x = 98   be equation (1)

Subtracting 98 on both sides of the equation , we get

x² - 7x - 98 = 0

Now , on simplifying the equation , we get

x² - 14x + 7x - 98 = 0

Taking x as the common factor of the equation , we get

x ( x - 14 ) + 7 ( x - 14 ) = 0

On further simplification , we get

( x + 7 ) ( x - 14 ) = 0

Now , the two solutions to the equation is

( x + 7 ) = 0

Subtracting 7 on both sides of the equation , we get

x = -7

( x - 14 ) = 0

Adding  14 on both sides of the equation , we get

x = 14

Therefore , the value of A is 14 or - 7

Hence , the equation x² - 7x - 98 = 0 has the solutions of 14 and -7

Answer:(-4,1)

Step-by-step explanation:

x: Since it said x+1 you move it over to the right one unit because the left to right is positive on a graph. So that would make the x-coordinate go from -5 to -4.

y: Since it said y-3 you would move it down three units because top to bottom is negative on a graph. so that would make the y-coordinate go from 4 to 1.

Answer:

I would say that Danny's deal is better.

Step-by-step explanation

If you wan t to know the better deal you should first figure out how much they charge per hour. All you have to do is divide the price by the amount of hours.

Danny: 44 ÷ 4 = 11

Martin: 42 ÷ 3 = 14    

Martin charges more money for fewer hours. Danny charges less for 4 whole hours, so he would be the better deal!!!

Step-by-step explanation:

Polynomials

Given the roots or zeros of a polynomial as x1, x2, x3, ...xn and the leading factor a, the polynomial can be expressed as:

[tex]P(x)=a(x-x_1)(x-x_2)(x-x_3)...(x-x_n)[/tex]

We are given the zeros of a polynomial as x1=0, x2=0 (multiplicity or zeros), and x3=-1, thus the polynomial is:

[tex]P(x)=a(x-0)(x-0)(x+1)[/tex]

Operating:

[tex]P(x)=a.x.x(x+1)[/tex]

[tex]P(x)=ax^2(x+1)[/tex]

[tex]P(x)=ax^3+ax^2[/tex]

Assuming a=1, the polynomial is

[tex]\mathbf{P(x)=x^3+x^2}[/tex]

Answer:

Following are the solution to this question:

Step-by-step explanation:

x was its full computer product revenue from March to December.  In january and february, the revenue towards products and services before x quantities for computer product revenues will happen between March to December is $2,500.  

Whenever x quantity is sold, then 0.05x quantity was sold for supplies and equipment.  

The sum of accessories to sell should be calculated, indeed, year-round.  

It helps us to split into two parts  

y = accessory sales in January and February + accessories sales in March and December  

Use item 2  

y = $2,500 + March to December accessories sale  

Now use sections 1 and 3  

y = $2,500 + 0.05x

The above equation rewriting gives  

y = 0.05x + $2,500 (a)  

This formula is compared with a standard y = mx+c interrupt slope  

We got a pitch of 0.05 and a pitch of $2,500.
