Answer:

Step-by-step explanation:

We know that the coin has 2 sides, which is tails and heads.

the total number of options is 2. whereas if tails or heads, 1 options

For tails:

[tex](\frac{1}{2}) *n[/tex]

[tex]\frac{n}{2}[/tex]

For heads:

[tex](\frac{1}{2} ) * n[/tex]

[tex]\frac{n}{2}[/tex]

If he does this in a row and expects 1 head and tail:

[tex]\frac{n}{2} * \frac{n}{2}[/tex]

Answer:

no we cannot because when we solve x-2=5 it gives x=7 and x+3=5 gives x=2 if we place the x value as 7 then it does not justify (x-2)(x+3)=5, if we put x= 2 then again it does not justifies (x-2)(x+3)=5

Step-by-step explanation:

x-2=5

x=5+2

x=7

x+3=5

x=5-3=2

putting x=7 in given equation

(7-2)(7+3) is not equal to 5

putting x=2 in given equation

(2-2)(2+3) is not equal to 5

that's why we can't solve

Answer:

2,340,208.5 or 2,340,209

Step-by-step explanation:

You could answer this by multiplying the current population of 800,000 by 1.05 (1.05 represents the annual growth rate of population) and do that 22 times.  But that would take a while.

we got 1.05 because the formula says that y = a( 1 + r ) power t

for a we will give it 1

so y = 1 ( 1 + 0.05) power t

it will give us 1.05

to do this faster, you would first calculate (1.05)22and then multiply this by 800,000.

So, 800,000 x (1.05)22 = 2,340,208.5 or 2,340,209

Answer:

-4x - 17y + 12

Step-by-step explanation:

I combined like terms

-3x + 5y - 10x - 14y+4+9 -8y + 9x - 1

= -4x - 17y + 12

This relation is a function. This is because no x value is repeated, so it passes the vertical line test.

Here is an example of where a relation is NOT a function:

{(2, 5), (3, –5), (2, 5), (5, –5)}

Answer:

Steps to find the equation of a line from two points:

Find the slope using the slope formula

Use the slope and one of the points to solve for the y-intercept (b).

One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.

Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.

Step-by-step explanation:

Well this is my way lol

mark brainliest if u want to cuz i need 5 more :)

Answer:

Step-by-step explanation:

You usually need to find the slope first.

When you have more than two points, you use the slope-intercept formula.

When you have one point and a slope, you use point-slope formula.

We can conclude that -

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

Given is a parallelogram ABCD.

Now, we can state that -

∠A = ∠C

(y + 10) = (2y - 40)

y + 10 = 2y - 40

y = 50

{Opposite angles are congruent}

(4x) + (2y - 40) = 180

4x = 180 - 60

4x = 120

x = 30

{Consecutive angles are supplementary}

Therefore, we can conclude that -

Function represent relationship between variables. The value of f[g(x)] when f(x) = 7x+13  and g(x) = x+2 is 7x+27.

A function assigns the value of each element of one set to the other specific element of another set.

Given to us

f(x) = 7x+13

g(x) = x+2

In order to find the value of f[g(x)], we will substitute the value of g(x) at the place of x in f(x).

[tex]f[g(x)] = 7(x+2)+13 \\\\ f[g(x)] = 7x+14+13 \\\\ f[g(x)] = 7x + 27[/tex]

Hence, the value of f[g(x)] when f(x) = 7x+13 and g(x) = x+2 is 7x+27.

The scale factor used to create the dilated Triangle M'S'V is 2/3.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the increase or decrease in the size of a figure by a factor k. If k > 1, it is an increment whereas if k < 1, it is a decrease.

Triangle MSV has vertex at M(-3, 3) while that of M'S'V' has vertex at M'(-2, 2). Hence the scale factor is 2/3

The perimeter of an object is the sum of all sides.

a book is a rectangle which has 4 sides. 2 sides would be the length and 2 sides would be the width.

Set up the equation:
70 = 20 + 20 + x + x

Simplify

70 = 40 + 2x

Subtract 40 from both sides

30 = 2x

Divide both sides by 2

To find area of first figure:

[tex] \\ [/tex]

As it is given in question shaded shape is made by joining a square and a rhombus. It is clearly visible that the first figure is square.

[tex] \\ [/tex]

So to find Area of a Square:-

We know :-

Area of square = side²

[tex] \\ [/tex]

So:-

[tex] \\ [/tex]

⇢ Area of square = side²

[tex] \\ [/tex]

⇢ Area of square = side × side

[tex] \\ [/tex]

⇢ Area of square = 5 × 5

[tex] \\ [/tex]

⇢ Area of square = 25 cm²

[tex] \\ [/tex]

Therefore Area of first figure is equal to 25 cm²

[tex] \\ [/tex]

To find area of second figure:

[tex] \\ [/tex]

So we have find area of square and now as in question given next shape is rhombus.

[tex] \\ [/tex]

There are two Formulas of rhombus :

[tex] \\ [/tex]

We have to use second formula as Digonals aren't given :

⇢ Area of rhombus = Base × Height

[tex] \\ [/tex]

⇢Area of rhombus = 4.5 × 5

[tex] \\ [/tex]

⇢Area of rhombus = (45 × 5)/10

[tex] \\ [/tex]

⇢Area of rhombus = (45 × 1)/2

[tex] \\ [/tex]

⇢ Area of rhombus = 45/2

[tex] \\ [/tex]

⇢ Area of rhombus = 22.5 cm²

[tex] \\ [/tex]

Therefore Area of first figure is equal to 22.5 cm²

[tex] \\ [/tex]

Area of whole shaded figure:

⇢A = Area of first figure + Area of second figure

[tex] \\ [/tex]

⇢ A = 25 + 22.5

[tex] \\ [/tex]

⇢ A = 47.5 cm²

[tex] \\ [/tex]

Therefore Area of whole shaded figure is equal to 47.5 cm².
