If a line crosses though (5,-3) and (-1,6);what is the y-intercept?

1 answer:

6 0

(5,-3) (-1,6)
y=mx+b

calculate m:
(-3-6)/(5-(-1)
=-9/6=-1.5

y=-1.5x+b

insert the (5, -3) point to calculate b:

-3=-1.5*5+b
-3=-7.5+b
4.5=b

b=the y intercept, so the line intercepts x=0 at y=4.5

What is the exact volume of a cylinder whose radius is 13 meters and whose height is 20 meters? Enter your answer, in terms of π

ddd [48]

Hello!

The equation to find the volume of a cylinder is

$V = \pi r^{2} h$

V is volume
r is radius
h is height

Put in the values you know

$V = \pi 13^{2} * 20$

Square the number

$V = \pi 169 * 20$

Multiply

$V = 3380 \pi$

The answer is $3380 \pi$

Hope this helps!

1. Michael rented a car for one day at a daily rate of $42. He also had to pay

rodikova [14]

Answer:

132 Miles

Step-by-step explanation:

First you must subtract $42 from $114.60.

$114.60 - 42 = 72.6$

Then, you need to divide $0.55 by $72.6.

$72.6 \div 114.60 = 132$

Hope this helped! :)

4x/3+3=x-2 value of x ?

Gekata [30.6K]

Answer:

x = - 15

Step-by-step explanation:

Given

$\frac{4x}{3}$ + 3 = x - 2

Multiply through by 3 to clear the fraction

4x + 9 = 3x - 6 ( subtract 3x from both sides )

x + 9 = - 6 ( subtract 9 from both sides )

x = - 15

Escribe 2 ejemplos de enunciados que establezcan una regla de correspondencia que represente una función y

Annette [7]

Answer:

Correspondencia entre conjuntos:

a) Inyectiva: es cuando a cada imagen en el conjunto de llegada le corresponde un único origen, es decir, a distintos elementos del conjunto inicial, les corresponden distintos elementos del conjunto final.

b) Sobreyectiva: es si todos los elementos del conjunto final tienen al menos una correspondencia del conjunto inicial

c) Biyectiva: es cuando la correspondencia es inyectiva y sobre inyectiva a la vez

Correspondencia unívoca : es una correspondencia donde cada elemento del conjunto origen se corresponde con solo un elemento del conjunto de llegada.

Correspondencia biunívoca es cuando a cada elemento del conjunto origen se corresponde con solo un elemento del conjunto llegada, y viceversa
