Find slope can anyone give me a step by step

Answers

Answer:

slope is 6/1 (or 6)

Step-by-step explanation:

your y-intercept is 3, so that means the point will be (0,3).

from there, you can start plotting points. up 6, over 1 (to the right)

the equation for a line is y=mx+b, so whatever number is in m will always be your slope, and whatever number is in b will be your y intercept

Mikaela is competing in a race in which she both runs and rides a bicycle. She runs 4.5 kilometers in 0.5 hour and rides her bicycle 18.75 kilometers in 0.75 hour. If she runs for 1 hour and bikes for 1 hour at the same rates as she does in the race, how far will she travel?

Answers

Answer:

25.67 km

Step-by-step explanation:

4.5 + 0.75 + 18.75 - 0.5 - 2 hrs = 25.67km

Answer:

about 35 km

Step-by-step explanation:

4.5 km divided by 0.5hour/30minutes = 6 min, 40 sec per km

18.75 divided by 0.75hour/45 minutes = 2 min 24 sec per km

60 divided 6.40 = about 9

60 divided 2.24 = about 26

26+9=35

3. What is the slope of 3y - 4x = 12?

Answers

Answer: (3,0)

Step-by-step explanation: x=0

3y=12

divide both sides by 3 you get

y=4   now you have y axis ( equation x=0) at the point its (0,4)

but if you put y=0 then you get

4x=12

and then x=3

so i think the answer is (3,0)

1. Un arquitecto construirá una casa de interés social en un área rectangular de 52 m². El
frente será el ancho de la casa y el largo será dos veces el ancho.
a.
Traza una figura geométrica que represente el terreno
b.
¿Cuál es la variable con la que representarías el ancho?

Answers

Answer:

Definamos:

A = Ancho

L = Largo.

Sabemos que el área es rectangular, y para un rectángulo de ancho A y largo L, el área es:

Área = A*L.

Y sabemos que L = 2*A.

a) Una imagen se encuentra abajo.

b) Como podemos escribir la variable L en términos de la variable A, podemos escribir:

Área = A*L = A*(2*A) = 2*A^2

Entonces la variable que usamos es el ancho.  

Ahora podemos resolver el problema:

52m^2 = 2*A^2

52m^2/2 = 26m^2 = A^2

A = √(26m^2) = 5.1 m

Entonces el largo es:

L = 2*A = 2*5.1m = 10.2 m

Meandre has 8 pints of milk. If he drinks ¼ of a pint of milk each day, how long will the 8 pints of milk last him?

Answers

Answer:

16 days

Step-by-step explanation:

1/4 = 0.25

8 divied 32

In multiplacation

8 time 4 = 32

8 pints of milk will last for 32 days.

What is Division?

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

Given that,

Total amount of milk Meandre has = 8 pints

Amount of milk drinking in 1 day = 1/4 pint

We have to calculate the number of days that 8 pints of milk will last.

Let x be the required number of days.

Using the concept of proportion,

(1/4) / 1 = 8 / x

1/4 = 8 / x

x = 8 × 4

x = 32

Hence total number of days that 8 pints of milk will last is 32 days.

which number makes the number sentence true? (6+9)+4=4+?
​

Answers

Answer

(6+9)+4=4+15

Step-by-step explanation:

First you would do (6+9) because it's in parenthesis. (6+9)= 15. So now our equation looks like 15+4=4+? Next we will do 15+4=19. 19=4+? is the new equation. Now the final step is to do 19-4=15 which is what we will plug into the equation.
