Answer:

y = 3x - 5

Step-by-step explanation:

First, you find the slope by finding the change in y and dividing that by the change in x of the two points.

-2 - 4 = -6, so -6 is the change in y.

1 - 3 = -2, so -2 is the change in x.

Then, since slope is change in y divided by change in x, you have -6/-2 = 3.

So far your equation is y = 3x + b and you're trying to find b to finish the equation.

To do this, you can pick one of the points and substitute the x and y values into the equation to find what value of b makes it true. Using (1, -2) we have

y = 3x + b --> -2 = 3(1) +b

-2 = 3 + b

b = -5

That means your equation is y = 3x  - 5

Answer:

-5t2 + 40t - 3

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant   5 • 3 = 15

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   -40 .

     -15    +    -1    =    -16

     -5    +    -3    =    -8

     -3    +    -5    =    -8

     -1    +    -15    =    -16

     1    +    15    =    16

     3    +    5    =    8

     5    +    3    =    8

     15    +    1    =    16

Answer:

20 degrees

Step-by-step explanation:

The sum of angle on a straight line is 180 degrees

x+20 + 7x = 180

8x + 20 = 180

8x = 180 -20

8x = 160

x = 160/8

x = 20

Hence the value of x is 20 degrees

Answer:

A

Step-by-step explanation:

well, you can plug in 6 for x to see if it comes out true. If it does. then yes 6 is a solution for the equation. If it doesn't, then it's no.

(6) + 13 = 18

19 = 18

So, the answer is no since 19 does not equal 18. So it's between A and B. Now you must read. Is it no because 6 + 13 = 18 is true or not true?

Well, since 19 does not equal 18, 6 + 13 = 18 is not true.

So the answer is A. No, because 6 + 13 = 18 is not true

Answer: i think A

Step-by-step explanation: 6+13 does not equal 18 it equals 19 that is

why I would choose A

Answer:

20 miles

Step-by-step explanation:

Subtract $28.00 and $3.00

$25

Then divide $25.00 by $1.25

20miles

The one passenger can travel 20 miles in thus budget.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Charge of taxi cab per person = $3.0

And per miles = $1.25

Budget of passenger = $28.00

Now, We have to calculate the distance that passenger can travel.

The amount without taxi cab charge = 28 - 3 = $25

So the distance = 25 / 1.25 = 20 miles

Thus, The one passenger can travel 20 miles in thus budget.

Answer:

a = -15, b = -.5, c = -1

Step-by-step explanation:

1/3a = -5 --> multiply each side with 3 --> a = -15

12 - b = 12.5 --> subtract 12 from both sides --> -b = .5 --> multiply each side with -1 to get b positive --> b = -.5

.1 = -10c --> multiply each side with -10 --> c = -1

Answer:

18 miles

Step-by-step explanation:

the ratio is miles/minute

10/50=0.2

so no just multiply the amount of minute you want 0.2*90= 18 miles

Answer and Step-by-step explanation:

In an hour and a half, Dana would go 18 miles since she's going a mile at regular intervals, so if she's trekking for an additional forty minutes, she will bicycle 8 miles. This implies that you'd increase five minutes by 8 miles (recall it's a mile for every 5 minutes) and that would give you forty. At that point simply add that to the 50 minutes she's been cycling as of now.

Answer:

x = 1/2

Step-by-step explanation:

First you want to get rid of the fraction, so you can multiply both sides of the equation by 3.

9 = 2x + 8

Then, subtract 8 from both sides to get x by itself.

1 = 2x

Finally, divide both sides by 2 so you only have one x

1/2 = x

This means that the answer is x = 1/2.

Answer:

x=1/2 or 0.5

Step-by-step explanation:

(2x+8)/3=3

(2x+8)=3x3

(2x+8)=9
