Final answer is 8.

Answer:

n = 7

Step-by-step explanation:

n+ 4 = 11       subtract 4 from both sides of the equation

n + 4 -4 = 11-4

n = 7

Hey there!

n + 4 = 11

SUBTRACT 4 to BOTH SIDES

n + 4 - 4 = 11 - 4

CANCEL out: 4 - 4 because it give you 0

KEEP: 11 - 4 because it help solve for the n-value

NEW EQUATION: n = 11 - 4

SIMPLIFY IT!
n = 7

Therefore, your answer is: n = 7

Good luck on your assignment & enjoy your day!

Answer:

[tex]y = 2x- 1[/tex]

Step-by-step explanation:

To determine which equation passes through the points (3, 7) and (-1, -1), we need to determine the slope of the equation. Then, we shall use point slope form to determine the equation of the line.

Determining the slope of the line:

[tex]\text{Slope} = \dfrac{\text{Rise}}{\text{Run} } =\dfrac{\text{y}_{2} - \text{y}_{1} }{\text{x}_{2} - \text{x}_{1} }[/tex]

Substituting the points in the slope formula:

[tex]\text{Slope} =\dfrac{-1 - 7 }{-1- 3 }[/tex]

Simplifying the slope:

[tex]\text{Slope} =\dfrac{-1 - 7 }{-1- 3 }[/tex]

[tex]\text{Slope} =\dfrac{-8}{-4 } = 2[/tex]

Determining the equation of the line:

We shall use point slope form to determine the equation of the line.

[tex]\text{Point slope form:} \ y - y_{1} = m(x- x_{1} )[/tex]

Substitute the slope and the coordinates of any two points stated above.

PLEASE ATTACH THE FIGURE LIKE THIS.....

Answer: as a square and four semicircles

Step-by-step explanation:

The composite shape area can be found by first decomposing the figure as: a square and four semicircles.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

to Find the Area of a Composite Figure:

To find the area of a composite figure, the first thing to do is to identify the individual shapes that make up the figure, then find the area of each shape before adding all the areas together.

For a composite figure that is comprised of a square and 4 semicircles, the composite figure would be decomposed into: a square and four semicircles.

Using proportions, it is found that 400g = 0.4kg of kiwi fruit contains approximately the same amount of Vitamin C as 1kg of oranges.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Kiwi fruit contains roughly two and a half times as much vitamin C as the same weight of oranges. Hence, if there is 1 kg = 1000g of oranges, the weight of kiwi fruit is given by:

1000/2.5 = 400g = 0.4kg.

We will see that the length of the browser window is 4.9 inches, and the screen is a square of sidelength 10.2 in

We know that the area of the browser window is 24 in^2, we will assume that the window is a perfect square, then the area is equal to the square of the length x, we have:

x^2 = 24 in^2

x = √(24 in^2) = 4.9 in

We know that the browser covers 3/13 of the screen, so the area of the screen is 13/3 times the area of the browser:

A = (13/3)*24 in^2 = 104 in^2

Again, if the screen is square of sidelength s, we have:

s^2 = 104 in^2

s = √(104 in^2)  = 10.2 in

Vertex form of parabola is the equation form of quadratic equation, which is used to find the coordinate of vertex points at which the parabola crosses its symmetry.

The standard equation of the vertex form of parabola is given as,

Step-by-step explanation:

The volume of the pyramid with a = 9cm, b = 15cm and l = 32cm is 720cm^3.

Answer:

720³ cm

The formula for volume is...

With that information, we should multiply the smaller numbers first.

[tex]B = \frac{1}{2} xy[/tex]

[tex]B = \frac{1}{2}(9)(15) = \frac{135}{2}[/tex]

If you observer the value of x=0 and x=1, you can conclude that every 1 value of x increased,

the f(x) will be increased by 0.5. The graph function should be: 

f(x)= x/2A positive difference means that the value should be always positive.
To find 3 the positive difference of f(x) with 3 values of x apart, let use x=0 and x=0+3= 3. The difference would be:

f(x+3) - f(x)f(3)- f(0)=1.5 - 0= 1.5The answer would be: 1.5
