Answer:
y = -3x -2.5
slope: -3
y-intercept: -2.5
Step-by-step explanation:
Solve for y.
-4y = 12x + 10 . . . . . add 12x to get the y-term by itself
y = -3x -2.5 . . . . . . .divide by the coefficient of y
__
The slope is the coefficient of x, -3.
The y-intercept is the constant, -2.5.
You began to do the equation from left to right. 8-10 = -2, so -2+5= 3, 3+6= 9f
Answer:
It would be rounded to $5.90 per gallon. As if something is 5 or above you round up and if it is 4 or less you round down.
Do your best remember volume is H+L+W and area is L*W
The first derivative gives you the formula for the slope of the tangent line to the curve at a given point.
<span>Find the first derivative of the function y=5x/x-2:
(x-2)(5) - (5x)(1)
dy/dx = ------------------------
(x-2)^2
simplify the algebra here.
(3-2)(5) - (15)(1)
Then, at the point (3,15), dy/dx = -------------------------- = -10
(3-2)^2
What is the equation of the tangent line? In other words, what is the eqn of the tan line to the given curve at when x = 3, if the slope is -10?
y-15 = -10(x-3)
This can be re-written in other forms if desired.
