Answer:

the slope is -4/3

Step-by-step explanation:

you can either use the graph or algebra to find the slope.

to use the graph, simply count how many spaces up/down and to the left/right that you go.

to use algebra, take the coordinates of your two points and do (y2-y1)/(x2-x1).

  /               =-2

1 - -3=4

2. The second part use this formula y-y1=m(x-x1)

     y--4=-1(x-3)

how do you find the measurement of an angle

Answers

You measure the size of an angle with a protractor. Or could be shown by an arc on the figure to indicate which angles that are congruent. Two angles whose measures together are 180° are called supplementary e.g. two right angles are supplementary since 90° + 90° = 180°.

Simplify the following expression. (19x + 4y) + (49x + 32y)

Answers

Answer: 68x + 36y

Step-by-step explanation:

Combine Like Terms:

= 19x + 4y + 49x + 32y

= (19x + 49x) + (4y + 32y)

= 68x + 36y

Hope this helped you!

Answer:

68x + 36y

Step-by-step explanation:

You can compeletely get rid of the parenthesis because it is addition through and thorough.

You have 19x + 4y + 49x + 32y

You can combine like terms to get

19x +49x which is 68x

and

4y + 32y which is 36y

You now have 68 + 36y which cannot be simplified anymore because the variables are different.

A bus travels at a speed of 40 miles per hour and reaches Hogville in 40 minutes. If a cab takes 35 minutes to reach the same spot, determine the speed at which it traveled.

Answers

Answer:

45.7miles per hour

Step-by-step explanation:

40mins = 2/3 hour

the bus travelled (2/3 x 40) miles = 80/3 miles

the cab took 35 mins (which is 7/12 hour) so it's speed is (80/3)/(7/12) miles/hour = 45.714 miles/hour (5 s.f.)

En cierto cultivo, inicialmente había 1000 amebas que se reproducen por biparticion cada día ¿Cuántas amebas habrá al cabo de 30 días después que se inició el cultivo ?

Answers

Answer: 1,073,741,824,000 amebas

Step-by-step explanation:

Bipartición significa que la población de amebas se duplica cada día.

Entonces si inicialmente hay 1000, después de un día van a haber:

2*1000.

Después del segundo día se vuelven a duplicar, entonces van a haber:

2*(2*1000) = (2^2)*1000

Después del tercer día, lo mismo:

2*(2^2)*1000 = (2^3)*1000.

A esta altura ya se puede ver el patrón, podemos concluir que después de N días, la población de amebas va a ser:

P(N) = (2^N)*1000.

Entonces respondiendo a la pregunta:

¿Cuántas amebas habrá al cabo de 30 días después que se inició el cultivo?

Tenemos que tomar N = 30

P(30) = (2^30)*1000 = 1,073,741,824,000 amebas

What is the value of M ?

Answers

Answer:

m = 124 degrees.

Step-by-step explanation:

The sum of the interior angles of a triangle is 180.

The angle opposite m + 56 + 68 = 180.

The angle opposite m = 56.

The angle opposite m + m = 180, so 56 + m = 180.

Angle m = 124.
