What is the system is equations 5x+4y=8 2x-3y=17
Tomtit [17]

Answer:

  (4, -3)

Step-by-step explanation:

The system of equations can be described a number of ways. One possible description is "a consistent pair of linear equations in two variables."

Perhaps you want to know the solution to this system of equations. I find it easiest to graph them. The attached graph shows the solution to be ...

  (x, y) = (4, -3)

__

You can also use "elimination" to simplify the system to a single equation in a single variable. Adding 4 times the second equation to 3 times the first will do that.

  3(5x +4y) +4(2x -3y) = 3(8) +4(17)

  23x = 92 . . . . . simplify

  x = 4 . . . . . . . .  divide by 23

Substituting this value into the first equation, we have ...

  5(4) +4y = 8

  5 +y = 2 . . . . . . divide by 4

  y = -3 . . . . . . . . subtract 5

The solution is (x, y) = (4, -3).

Escribe and correct the error in finding the simple interest earned on $500 at 6% for 18 months. I=500(0.06)(18) I = 540
PIT_PIT [208]

Answer: 45$

Step-by-step explanation:

Given

Principal P=\$500

Rate R=6\%

time t=18\ \text{months or}\ 1.5\ \text{years}

Simple interest is given by

\Rightarrow S.I.=\dfrac{P\times R\times T}{100}

In the question, time is taken in months which is incorrect

Putting values

\Rightarrow S.I.=\dfrac{500\times 6\times 1.5}{100}=45\$
