How many solutions does the system of equations have 3x=-12+15 and x + 4y =5

Answer:

infinitely many solutions

Step-by-step explanation:

I assume that you meant

3x = -12y + 15 and x + 4y =5 (you accidentally omitted the 'y')

Multiplying the second equation by 3 yields

3x + 12y = 15

... which is identical to the first equation.  Thus, the two lines coincide, and we conclude that there are infinitely many solutions.

Evaluate the function f(x) at the given numbers (correct to six decimal places).
statuscvo [17]

Answer:

The values of given function are shown in the below table.

Step-by-step explanation:

The given function is

f(x)=\frac{x^2-5x}{x^2-x-20}

Simplify the given function.

f(x)=\frac{x(x-5)}{x^2-5x+4x-20}

f(x)=\frac{x(x-5)}{x(x-5)+4(x-5)}

f(x)=\frac{x(x-5)}{(x+4)(x-5)}

Cancel out the common factor.

f(x)=\frac{x}{x+4}

Substitute x=5.5 in the above equation.

f(5.5)=\frac{5.5}{5.5+4}

f(5.5)=\frac{5.5}{9.5}

f(5.5)=0.57894736842

f(5.5)\approx 0.578947

Similarly find the value for all values of x.

The values of given function are shown in the below table.

What was the population of south Australia closest to in 2003?
Brrunno [24]
It would be 1531600

How I did it
 First I divided the percentage by 100. Example >> 0.6/100= 0.006
  Then I took 2002 population >> 1522475 +  0.006  x  1522475 = 1531609.85

PLEASE HELP ME OUT
igomit [66]

Answer: D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.

Step-by-step explanation:

You do not know how much a 20% discount is unless you know the price of the shirt. This can be more or less than $20, so you don’t know.

Hope this helps!
