how many would juile see?

We want to see how many different 4-digit passwords we can create by using digits from 0 to 9, such that the first character can't be 0.

We will see that the correct option is D: 9,000

The total number of different combinations is given by the product between the number of options for each selection.

Here we have 4 selections.

Now let's find the number of options for each of these:

The total number of different combinations is just the product of these 4 numbers:

C = 9*10*10*10 = 9,000

So we can conclude that the correct option is D.

Answer:

y = - [tex]\frac{1}{2}[/tex] x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{1}{2}[/tex] , then

y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (2, - 2 ) into the partial equation

- 2 = - 1 + c ⇒ c = - 2 + 1 = - 1

y = - [tex]\frac{1}{2}[/tex] x - 1 ← equation of line

Answer:

y=-1/2x-1

Step-by-step explanation:

y-y1=m(x-x1)

y-(-2)=-1/2(x-2)

y+2=-1/2(x-2)

y=-1/2x+2/2-2

y=-1/2x+1-2

y=-1/2x-1

Answer:

Algebra is a abstract way of thinking about things. We usually see this by defining things we don't know as some sort of symbol (Matter of fact. All of Mathmatics revolves around symbols). It doesn't necessarily have to be a number. I could label some big brown sturdy thing with green stuff on top as a tree which in a mathmatical sense the tree would be the variable and the actual thing would be the thing inside of the variable. But basically it's an abstract way of thinking

Answer:

10 dimes and 6 quarters.

Step-by-step explanation:

2.50-25-25=2.00-10 dimes = 1.00-4 0.25=0

so

10 dimes and 6 quarters.

Answer:

10 Dimes and 6 Quarters.

Step-by-step explanation:

Important info:

16 Coins

Total = $2.50

Note:

Dimes = 0.10 Cents

Quarters = 0.25 Cents

Question to answer:

How many of each type of coin does she have?

Solution:

10 Dimes = $1.00

6 Quarters = $1.50

$1.00+$1.50 = $2.50

Therefore 10 Dimes and 6 Quarters = $2.50 and = 16 Coin.

Step-by-step explanation:

Answer:

D.

Step-by-step explanation:

The question is asking which expressions are the same. To find the answer, or rather confirm it, you should simplify each expression.

A. 8+(3*y) and (8+3)*y

8+3y and 11y

This cannot be the answer, when simplified they are not equal

B. (7-3)*y and 7-(3*y)

4y and 7-3y

This cannot be the answer, when simplified they are not equal

C. (6/y)+13 and 13+(y/6)

13+6/y and y/6+13

This cannot be the answer, when simplified they are not equal

D. 7+(y*5) and 7+(5*y)

7+5y and 7+5y

This is the answer, when simplified they are equal

I hoped this helped and made it easier to understand! :)

Answer: y = 1x + -4

Equation of a straight line:

y = mx + b ------(i)

Step by Step Solution:

Step 1: Calculating Slope (m).

m = y2-y1 /x2-x1

m = 3--1 /7-3

m = 4/4

m = 1

Now putting value of m in equation (i)

y = 1x + b -----(ii)

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (3,-1) for calculating y-intercept:

y = mx + b

-1 = 1(3) + b

-1 = 3 + b

-4 = b

b = -4

Now putting value of b in equation (ii)

y = 1x + -4

[tex]y \propto \dfrac 1x\\\\\implies y = \dfrac kx[/tex]

Hope you could get an idea from it.

Answer:

The parallelogram whose sides are 5 and 20  is similar

Step-by-step explanation:

The parallelogram whose sides are 5 and 20  is similar to the given parallelogram whose sides are 2 and 8 because the figures are the same shade and corresponding sides are proportional.

 [tex]\frac{2}{5} = \frac{8}{20}[/tex]                 [tex]\frac{2}{4} \neq \frac{8}{18}[/tex]
