Answer:

  3 minutes

Step-by-step explanation:

Let x represent Alysha's time to drive home from the market.

Speed and time are inversely proportional to each other (for the same distance), so we have ...

  (walking speed)(walking time) = (driving speed)(driving time)

  5(x +21) = (8·5)(x)

  x +21 = 8x . . . . . . . . . divide by 5

  21 = 7x . . . . . . . . subtract x

  3 = x . . . . . . .divide by 7

It takes Alysha 3 minutes to drive home from the market.

Expressions can be expressed as equations or as inequalities.

The difference is that the variables in a system of equation have one solution each, while in a system of inequalities, the variables have a range of values.

Let the system of equation be:

[tex]\mathbf{ax + by = c}[/tex]

[tex]\mathbf{dx + ey = f}[/tex]

Let the system of inequality be:

[tex]\mathbf{ax + by < c}[/tex]

[tex]\mathbf{dx + ey > f}[/tex]

Both systems can be solved using the same method, such as: graphs, substitution and elimination.

However, the difference is that:

In a system of equation, the variables can have one solution each, while in a system of inequalities, the variables have a range of values.

Answer:

x = 6

Step-by-step explanation:

5x-3 = 2x+15

5x-2x-3 = 15

5x-2x = 15+3

3x = 15+3

3x = 18

Answer:

A does not represent a function

Answer:

Step-by-step explanation:

Multiply -3 for x and for 5

-3x-15=27

When you have this type of equation the first thing you do is take off the parentesis

Then you pass the 15 to the other side and you get -3x= 27 +15 . After that you divide that for -3 and you get the x . In this case x= -14

Answer:

$11.93

Step-by-step explanation:

You can write an equation to represent this scenario, where x is the number of minutes spent on the call and y is the total cost of the call.

[tex]y=0.99x + 5.99[/tex]

Plug in 6 for x:

[tex]y=0.99(6)+5.99[/tex]

Multiply 6 x 0.99, representing the fact it costs 99 cents per each minute spent on the call:

[tex]y=5.94+5.99[/tex]

Add the sum of the $5.99 cost to connect the call, plus the charge ($5.94) for spending six minutes:

[tex]y=11.93[/tex]

Your answer is $11.93!

Answer: 30 cm

Step-by-step explanation: Take note that ^2 means to the second power.

a^2 + b^2 = c^2 (hypotenuse)

18^2 + 24^2 = c^2

324 + 576 = c^2

900 = c^2

To find the length of c you have to find teh square root of 900.

√c^2 = √900

c = 30

The length of the hypotenuse is 30 cm!

Answer:

31, 33, 35

Step-by-step explanation:

Let 2n+1 be the first odd number. What will the next one be? Add two:

Let 2n+3 be the next odd number. Again, what is the next one? Add two:

Let 2n+5 be the third odd number.

The sum of those three numbers must be 99. You don't have to have the parenthesis here, but I think they help clarify where everything comes from.

(2n+1) + (2n+3) + (2n+5) = 99

Add like terms, and solve for n:

6n + 9 = 99

6n = 90

n = 15

The three odd numbers we want are:

2(15)+1 = 31

2(15)+3 = 33

2(15)+5 = 35

Double check: 31+33+35 = 99?

Answer:

(images to help with graph are below)

Step-by-step explanation:

okay! so once you get the hang of this, it is super super easy.

so the y-intercept is a point on that long line going up and down on the graph. it shows where the line intersects the middle!

so here it says that the y-intercept (y-int for short) is 2. so we will simply mark a little point on 2.

now the slope. the slope is -4. this can be written as -4/1. the -4 is on the top so i represents the y values. and the 1 is on the bottom so it represents the x values.

we know that when graphing, x goes from side to side and y goes up and down.

if an x value is positive you move it to the right (forwards), if it is negative you move it to the left (backwards). if a y value is positive you move it upwards, if it is negative you move it downwards. so we want to start graphing with our x.

The x value is 1 (because it is in the bottom of the slope! -4/1!). So we will move one point from the y-int (the point we marked).

Now for the y values. The y value is -4 (again, taken from the -4/1. the top number is the y value). FROM THE PLACE WE LEFT OFF FOR THE X VALUES (we left off at point (1,2) because we moved it one to the right!), we will move 4 points DOWN because it is negative (-4). Mark this place with a dot!

We should now have the points (0,2) and (1,-2) marked with a dot. draw a line through the 2 dots! this is ur finished graph. notice how the line intersects the middle on the y-intercept!! that will always happen.

Lastly, the equation! the formula for slope intercept form is y=mx+b

m is always your slope. b is your y-int. and y and x stay blank (for now. in the future you might use those spots). so simply fill in m and b!

the slope is -4. so m = -4

the y-int is 2. so b = 2

the finished equation should look like this:

y = -4x + 2

I hope this helped !!!
