voici mon travail.
this week i math 10 we learned some new terms for arithmetic sequences.
here are a couple of examples that we learned.
Find the 25th term if the common difference = 10 and starts at 2 To solve this sequence, we follow this basic rule: tn=t1 + (n-1)d. We can replace “tn”
this week in math 10 we learned elimination
To solve elimination you need line the two equations together like you were about to add/subtract,
the next step would e to try to get a zero pair. you would need to multiply the equation to get a zero pair. once u got your zero pair add the two together to isolate x or y
once that is done you can now you can solve for the other equation using the best friends share desserts.
Thats how you would use elimination to solve a system
This week in math 10 we learned how to use substitution to solve a system. To start off you need to pick if you want to solve using X or Y.
once you have picked which variable you want to solve with you need to isolate the variable to get the one you picked alone
here is my example:
x+y=1.3 ——- Y= 1.3-x
that is the equation because you subtracted x to both sides.
then you need to insert y=1.3-x into the second equation where y i.
now you need to subtract 52 on both sides
thats how you do substitution.
This week we learned about different slope equations
to find the midpoint you do y1+y2/x1-x2
To find the distance you either do y1-y2 or x1-x2 or use pythagorean theorem.
This makes it super easy to find the distance and the midpoint.
This week we talked about slopes.
we talked about horizontal vertical and oblique lines
oblique lines are on angles
horizontal are equal to zero
vertical lines are equal zero
The easiest way to remember is slope guy!
This week in math 10 we learned 3 important equations.
Point slope form, Slope y-intercept form and General form.
My personal favorite in point slope.
This is what a point slope for equation would look like:
This is general form:
This is slope y intercept form
