Answer:

x = -6/5

Step-by-step explanation:

distribute -4 on the left side of the equation first, then distribute 2 on the right side of the equation to get:

16x - 4 - 4x = 2x - 14 - 2

combine 'like terms':

12x - 4 = 2x - 16

subtract '2x' from each side to get:

10x - 4 = -16

add 4 to each side to get:

10x = -12

x = -12/10 or x = -6/5

Family traveled 25 miles in 1/2 hour. If it’s currently 3:00 pm and the destination is 225 miles away, what time will they arriv

dangina [55]

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM

Step-by-step explanation:

We have to calculate the speed first to find the time it will take the family to complete the trip.

Given

Distance = d = 25 miles

Time = t = 1/2 hours = 0.5 hours

$Speed =\frac{d}{t}\\=\frac{25}{0.5}\\=50 miles\ per\ hour$

Now,

Distance remaining = 225 miles

Speed = 50 miles per hour

$s=\frac{d}{t}\\t=\frac{d}{s}\\t=\frac{225}{50}\\t=4.5\ hours$

As we see that the time required to complete the journey is 4.5 hours.

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM

Answer:

a. 0

Step-by-step explanation:

1. To find the slope given two points, use the following formula:

$\frac{y^{2}- y^{1} }{x^{2}-x^{1} }$

2. $y^{2}$ would be the second y-value (in the second ordered pair), 2, and $y^{1}$ would be the first y-value (in the first ordered pair), also 2.

3. Same for the x-values. $x^{2}$ is -2 and $x^{1}$ is 4

4. Now plug in the values.

$\frac{2-2}{(-2)-4}$

5. This equals $\frac{0}{-6}$ which simplifies to 0
