Answer:

$\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

$\frac{y_2-y_1}{x_2-x_1}$

the 2 and 1 represent which number they are in a series of points. For example, if I were to have points (1,2) and (3,4)

4 would be $y_2$ meaning it is the second y value

2 would be $y_1$ meaning it's the first y value

Same goes for x

3 is $x_2$

1 is $x_1$

so the equation for slope is $\frac{4-2}{3-1}$ , or 1

Answer:

You are correct. Remember: rise over run.

m = $\frac{y2-y1}{x2-x1}$

Answer:

5. f(x) = 10,000 (1.5)^x

Step-by-step explanation:

We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.

Let's test it.

Initial:

10,000

After 1 year

10,000 + (.5*10000)

10,000 + 5000 = 15,000

After 2 years

15,000 + (.5*15000)

15,000 + 7500 = 22,500

Let's try our equation.

f(x) = 10,000 (1.5)^x

x = 2

10,000(1.5)^2

10,000(2.25) = 22,500

The same!

What is the formula for the area of a triangle?

SashulF [63]

The formula to find the area of a triangle is :

1/2 base*height

For instance:

base=4 cm

height=5cm

area of traingle=1/2*b*h

 =1/2*4*5

 =10cm^2

Hope it helps...

Good luck on your assignment

Please help ASAP. What is the length os side BC of the triangle

Nuetrik [128]

nswer:

B C = 24

Explanation:

The triangle is isosceles, because (from the diagram) ∠ A B C = ∠ A C B - note how the angle there is marked on both of these. If these angles are equal, this means that the sides

A C = A B

let A C = A B

x +8=2x-1

8 = x − 1

x = 9

We want to find the length of

B C , which is ( 3 x − 3 ) . We know that x = 9

B C =3 x − 3

B C = 3 ( 9 ) −3

B C = 27 − 3

B C = 24
