The equation of any straight line on a graph is y = mx + c
m = gradient = rise/run = 4/1 = 4
c = where it cuts the y axis = -3
the equation of the line is y = 4x - 3
Dy=y'*dx
=8x*dx
=8(5)*0.4
=40*0.4
=16
Answer:
Look at the explanation.
Step-by-step explanation:
Start y=-2x-3 at the Y -3 and X 0, then go up two and to the right one, like a staircase. For y=-x+3 start on Y 3 and X 0 and go down 1 x and 1 y like a downstair staircase with 1 unit down.
Answer:

Step-by-step explanation:
The given expression is

Where
and
.
When we say "evaluate the expression" refers to replacing the given values in the expression. Then, we solve each power in the numerator and denominator. After that, we solve each product in the fraction. At the end, we apply the square power. As follows
