Answer:
x= -1
y = 9
Step-by-step explanation:
to solve this system of equation
let
x - 2y = -19.....................................equation 1
-3x + 5y = 48 .................................. equation2
from equation 1
x - 2y = -19.....................................equation 1
x = -19 + 2y................................... equation 3
substitute the value of x into equation 2
-3x + 5y = 48 .................................. equation2
-3(-19 + 2y) + 5y = 48
57 - 6y + 5y = 48
combine the like terms
-6y + 5y = 48 -57
-y = - 9
divide both side by -
y = 9
put y= 9 into equation 3
x = -19 + 2y................................... equation 3
x = -19 + 2(9)
x = -19 + 18
x = -1
therefore the value of x and y is -1 and 9 respectively
The derivative of a function can be viewed geometrically through the slope of the graph of the function or through the slope of the tangent line at a point.
<h3>What is Function?</h3>
This is referred to as a mathematical term which is used to describe the relationship between two variables which are referred to as the independent and the dependent variable.
The derivative of a function is denoted as the rate of change of the variables and can be viewed geometrically through calculation of the slope of the graph of the function or through the slope of the tangent line at a point.
This is therefore the reason why it was chosen as the most appropriate choice.
