Answer:
the width is 15
Step-by-step explanation:
Answer: A) 3x + 5x - 4 = 1
<u>Step-by-step explanation:</u>
The second equation is y + 4 = 5x. Solve this equation for y by subtracting 4 from both sides. --> y = 5x - 4
Now replace "y" in the first equation with "5x - 4".
3x + y = 1
--> 3x + (5x - 4) = 1
The slope is
1. Find ordered pairs ( 1 , -4 ) ( 3, 3)
The formula is
M= y2 - y1
_____
X2- X1
2. Replace the numbers
M = 3 - 4.
———
1-3
Subtract
3. You get -1/-2
4. Divide you get 0.5
( but if you need rise and run use -1/-2) rise top run bottom
Slope is 0.5 I think
Hope this helps here a picture of my lesson.
In 6 month they will have the same number of stamps. sorry... idk the other part
Note that if
, then
, and so we can collapse the system of ODEs into a linear ODE:
which is a pretty standard linear ODE with constant coefficients. We have characteristic equation
so that the characteristic solution is
Now let's suppose the particular solution is
. Then
and so
Thus the general solution for
is
and you can find the solution
by simply differentiating
.
