Hi, it is well simples!

Look :

a = Delta(y)/Delta(x)

Where,

Delta(y) = yf - yi

Delta(x) = xf - xi
_______________

As yi = 4 and yf = 1

And

xi = -3 and xf = 2

Then,

a = (1-4)/(2-(-3))

a = (-3)/(2+3)

a = -3/5

Rudik [331]

Answer:

C = (A*P - 8.4Y -330T + 200I) / 100

Step-by-step explanation:

P = (8.4Y + 330T + 100C -200I ) / A

now we have to calculate completed passes C for given P, Y, T, I, A

A*P = 8.4Y + 330T -200I +100C

100C = A*P - 8.4Y - 330T + 200I

C = (A*P - 8.4Y -330T + 200I) / 100

I just solved the equation for C

(6) Give the equation of the line passing through the points (1,5) and (-2, 6) in

Bas_tet [7]

Answer:

⅓x + y = 5⅓

⅓x + y = 5.3333333

⅓x + y = 16/3

Step-by-step explanation:

Solve for slope using rise/run

Y2 - Y1 / X2 - X1

(6) - (5) / (-2) - (1)

1 / -3

Slope: -⅓

y = -⅓x + b

solve for b using one of the points

I'll be using (1,5)

Substitute the point into the equation

5 = -⅓(1) + b

5 = -⅓ + b (add ⅓ to both sides)

+⅓ +⅓

5⅓ = b

5⅓ can also be written as 16/3 or 5.333333

The equation is now:

y = -⅓x + 5⅓

Convert to standard form by adding ⅓x to both sides

y = -⅓x + 5⅓

+⅓x +⅓x

Solution: ⅓x + y = 5⅓

What is the volume of the pyramid 7x7x8

dolphi86 [110]

Answer:

The volume of the pyramid is $130\frac{2}{3}\ units^{3}$

Step-by-step explanation:

we know that

The volume of the pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the base

H is the height of the pyramid

In this problem we have a square base

$B=7^{2} =49\ units^{2}$

we have

$H=8\ units$

substitute

$V=\frac{1}{3}(49)(8)=\frac{392}{3}\ units^{3}$

Convert to mixed number

$\frac{392}{3}=\frac{390}{3}+\frac{2}{3}=130\frac{2}{3}\ units^{3}$
