Two cars leave a town at the same time heading in opposite directions. One car is traveling 12 mph faster than the other. After

2 hours, they are 232 miles apart. What is the speed of each car? 52 mph; 64 mph 55 mph; 70 mph 92 mph; 104 mph 98 mph; 110 mph?

D = rt.  The first car's rate is r, and the other one, going faster, is r + 12.  The time they travel is 2 hours.  Since one is going faster than the other, he has gotten farther.  But, regardless of that, the distance between them is 232.  So the distance the first one travels, r*t, which 2r, plus the distance the second one travels, 2(r+12) = 232.  2r + 2r + 24 = 232.  Solve for r.  4r = 208 and r = 52.  The slower one goes 52 and the faster one goes 64

The first cars speed is X miles per hour.
 The 2nd cars speed is X + 12 miles per hour

X + X +12 = 232 / 2

2x +12 = 116

2x = 116-12

2x = 104

x = 104 / 2
x = 52

x+12 = 52+12 = 64


 The 2 cars are driving 52 and 64 miles per hour

Describe the graph of y=3/4x-12 as compared to the graph of y=1/x
Eddi Din [679]

Answer:

Parent function is compressed by a factor of 3/4 and shifted to right by 3 units.

Step-by-step explanation:

We are asked to describe the transformation of function y=\frac{3}{4x-12} as compared to the graph of y=\frac{1}{x}.

We can write our transformed function as:

y=\frac{3}{4(x-3)}

y=\frac{3}{4}*\frac{1}{(x-3)}

Now let us compare our transformed function with parent function.

Let us see rules of transformation.  

f(x-a)\rightarrow\text{Graph shifted to the right by a units},

f(x+a)\rightarrow\text{Graph shifted to the left by a units},

Scaling of a function: a*f(x)

If a>1 , so function is stretched vertically.

If 0<a<1 , so function is compressed vertically.

As our parent function is multiplied by a scale factor of 3/4 and 3/4 is less than 1, so our parent function is compressed vertically by a factor of 3/4.

As 3 is being subtracted from x, so our parent function is shifted to right by 3 units or a horizontal shift to right by 3 units.

Therefore, our parent graph is compressed by a factor of 3/4 and shifted to right by 3 units to get our new graph.

Answer:

  a = 9 meters

Step-by-step explanation:

The perimeter is the sum of the side lengths:

  28 m = a + 2m + a + 8m

  18 m = 2a . . . . . . . . . . . . . . . . subtract 10m, collect terms

  9 m = a . . . . . . . . . . . . . . . divide by 2

The value of a is 9 meters.
