7x -2(x-11)=-103
what is x

Answer:

Step-by-step explanation:

Original price = x

75% of 70% of x = $42

0.75*0.70x =$42

x = $42/(0.75*0.70) =$42/0.525 = $80

Given:

The two points are (-2,3) and (-4,-2).

To find:

The gradient of the line segment between the given points.

Solution:

The gradient is also known as slope.

The slope formula:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The endpoints of the line segment are (-2,3) and (-4,-2). So, the gradient of the line is

[tex]m=\dfrac{-2-3}{-4-(-2)}[/tex]

[tex]m=\dfrac{-5}{-4+2}[/tex]

[tex]m=\dfrac{-5}{-2}[/tex]

[tex]m=\dfrac{5}{2}[/tex]

Therefore, the gradient of the given line segment is [tex]m=\dfrac{5}{2}[/tex].

Answer: x+5 or ((x^2+8x+15)/(x+3))

Step-by-step explanation: First let's assign our variables.

x^2+8x+15 = Area

X+3 = Width

? = Length

If the equation of a=lw, then we can substitute in our variables.

a=lw

x^2+8x+15= L (x+3)

Now we must isolate L.

Divide both sides of the equation by 'x+3'

x^2+8x+15= L (x+3)

x+3                 x+3

x+5= L

Answer:

The only difference between the two equations is that, a linear equation gives a line graph whereas a linear inequality shows the area of the coordinate plane that satisfies the inequality. A linear inequality graph usually uses a borderline to divide the coordinate plane into two regions.

Step-by-step explanation:

Evaluate

Answer:

1. T(d) = A(d) + B(d)

2. T(d) = 12d + d²

Step-by-step explanation:

From the question given above, the following data were obtained:

A(d) = 10d

B(d) = 2d + d²

1. Determination of the formula of T(d) in terms of A(d) and B(d).

T(d) is the total money obtained. Thus,

T(d) = A(d) + B(d)

2. Determination of the formula of T(d) in terms of d.

A(d) = 10d

B(d) = 2d + d²

T(d) =?

T(d) = A(d) + B(d)

T(d) = 10d + 2d + d²

T(d) = 12d + d²

Step-by-step explanation:

both subtracted: −8x2−7x−1

Answer: the answer is y=-22x+86

here is why:

the slope is -22 which is the m --> y=mx+b the point is (4,-2) the x=4 and y= =2

If we set up the equation:

-2= -22(4)+86

-2= -88+86

-2= -2

Answer: inequality???? -4x < 8 flip sign

Solved would be x < 2

Answer:

X = - 12.

Step-by-step explanation:

17 = 5 - x

17 = 5 + - x

17 = - x + 5

Then, flip the equation.

-x + 5  = 17

Then subtract 5 from both of the sides.

-x + 5 - 5 = 17 - 5

-x = 12

Then divide

-x/ -1 = 12/1

x = - 12.

Hope this helps!

Answer:

V = 167.55 m³

Step-by-step explanation:

Given that,

The height of a cone, h = 10 m

Radius of the cone, r = 4 m

It can be assumed to find the volume of the cone. Th formula for the volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h\\\\V=\dfrac{1}{3}\pi \times (4)^2\times 10\\\\V=167.55\ m^3[/tex]

So, the required volume is 167.55 m³.

Answer:

96 = x

Step-by-step explanation:

I'm going to use cents instead of dollars because I find decimals and fractions to be cumbersome. I assume you meant $.005 instead of 4.005.

Let x denote the price (in cents) of the 12-ounce can. Then the price of the 16-ounce can is (x + 16) cents, and the price of the 24-ounce can is ((x + 16) + 68), or (x + 84) cents.

The unit price (cents per ounce) of the 12-oz can is x/12

The unit price of the 16-oz can is (x + 16)/16

The unit price of the 24-oz can is (x + 84)/24

You are told that, in terms of x,

(x + 84)/24 = x/12 - 0.5

Multiply both sides by 24:

x + 84 = 2x - 12

Solve for x:

96 = x

So the unit prices (in cents per ounce) are:

12 oz: 96/12 = 8 cents/oz

16 oz: 112/16 = 7 cents/oz

24 oz: 180/24 = 7.5 cents/oz

So the 16 ounce can is the best buy based on lowest unit price.

In this exercise we have to use the knowledge of finance to calculate the best price to be offered, in this way:

[tex]12 oz: 96/12 = 8 cents/oz\\16 oz: 112/16 = 7 cents/oz\\24 oz: 180/24 = 7.5 cents/oz[/tex]

Some values ​​should be simplified as they were informed in the statement:

So putting together an equation with these values ​​and terms informed we find that:

[tex](X + 84)/24 = X/12 - 0.5\\X + 84 = 2X - 12\\X=96[/tex]

So with the value of X found it is only necessary to use the previous equations and replace this value.

Answer:

-6665

Step-by-step explanation:

The given GP is :

1, -6, 36, ...

Number of terms = 6

The sum of n terms of a GP is given by :

[tex]S_n=\dfrac{a(r^n-1)}{r-1}[/tex]

Here,

a = 1, n = 6, r = 36/-6 = -6

So,

[tex]S_6=\dfrac{1((-6)^6-1)}{(-6)-1}\\\\=-6665[/tex]

So, the sum of th GP is -6665.
