Hey!

---------------------------------------------------

Point Slope Form: y - y1 = m(x - x1)

---------------------------------------------------

Answer: y + 8 = -4(x - 2)

The reason why I put y + 8 is because when you subtract a negative number it changes to adding a positive number. (- -8 ---> + 8)

Hope This Helped! Good Luck!

Answer: 9:14

Step-by-step explanation: So if he started if 1 bacteria, it becomes 2 bacteria at 9:01, etc. So at 9:13, it is 2^13 and if that is half, that means 2^14 is when it is full so 9:14.

A car can travel 247 kilometers on 19 liters of gasoline. how much gasoline will it need to go 429 kilometers?
7nadin3 [17]

find the number of miles per 1 liter:

247 kilometers / 19 liters = 13 kilometers per liter.


Divide how may kilometers they want to go by kilometers per liter:

429 kilometers / 13 kilometers per liter = 33 liters are needed.

choose the equation in point slope form for the line that is perpendicular to the given line and passing through the given point
alexdok [17]

We want to determine the equation in point slope form for the line that is perpendicular to the given line and passing through the point (5.6) .

The equation and the point is;

y=\frac{2}{3}x+9,(5,6)

We know that for two lines to be perpendicular, the product of their slopes should be -1.

Therefore, the slope of the perpendicular should be;

m=-\frac{1}{(\frac{2}{3})}=-\frac{3}{2}

The second condition is that the line must pass through the point (5,6) , to do thid, we write the equation of the line in point slope form which is;

y-y_1=m(x-x_{1_{}})

Inserting all values, we have,

y-6=.-\frac{3}{2}(x-5)

That is the final answer.

Cual de estos utiliza la propiedad distributiva para mostrar la forma expandida de la expresion: -4 . (-5 + 3)
mr Goodwill [35]

Respuesta:

8

Explicación paso a paso:

Si A, B y C son números enteros, según la propiedad distributiva;

A (B + C) = AB + AC

tenga en cuenta que A se distribuyó sobre B y C

Aplicando esto para expandir la expresión dada -4. (-5 + 3)

-4. (-5 + 3)

= -4 (-5) + -4 (3)

= 20 + (-12)

= 20 - 12

= 8

Por lo tanto, la respuesta requerida es 8
