Norma-Jean [14]3 years ago
7 0

Answer:

(x,y)=(3/2, -1/2)

Step-by-step explanation:

2x+4y=1  /*3

3x-5y=7  /*(-2)

6x+12y=3

-6x+10y=-14

...........................

/      22y=-11

      y= -11/22

     y= -1/2

2x+4*(-1/2)=1

2x-2=1

+2     +2

2x=3

x=3/2

so the solutionis (x,y)=(3/2, -1/2)

Consider the function f(x). Select all of the following that include a vertical stretch of f(x)
zhenek [66]

Answer:

F , D, A

Step-by-step explanation:

As we know vertical stretch of f(x)  happens when we chane the value of the patameter a in this general form:

y = a. f(k(x-d))+ c  

when  |a| > 1 because When |a| > 1 (when a is greater than 1), the function is stretched vertically by a dilation factor of |a|.

So we choose, F , D, A

The population of Canyon Edge is 210,000, and the rate of population growth is 12.5%.
sergejj [24]
For this case we have a function of the form:
 y = A * (b) ^ x

 Where,
 A: initial population
 b: growth rate
 x: number of years.
 We then have the following function:
 y = 210000 * (1,125) ^ x

 For x = 4 years we have:
 y = 210000 * (1,125) ^ 4

 y = 336379
 Answer:
 
the formula for exponential growth is:
 
y = 210000 * (1,125) ^ x
 
The population of Canyon Edge after 4 years is:
 
y = 336379

Solve the equation x to the 3 power = -215
mojhsa [17]

Answer:

cube root of -215 or -5.9

Step-by-step explanation:

Since this can't be a perfect cube the answer would be cube root of -215 or you find the closest perfect cubes which would be -5 and -6

-5cubed is -125 and -6cubed is -216  and -215 is closer to -216 the number approximately would be -5.9

Hope this helps :)
