This last week we learned how to graph different types of equations
Grade 10 question
y=x+7
Now we are looking to solve this as an inequality
y>x-4
Right now we have 50% chance of getting it right
But by testing the inequality by putting 2 points in as a check (verify)
I like to use the points (0,0)
y=x-4
0, 0-4
0>-4 (CORRECT)
so the side would shaded in including (0,0)
Recently I was looking back over my blog posts for Math 10, and I realized that I never did a blog posts for the different numbers groups. I was surprised about the fact that I didn’t do a blog for the number groups because it is the simplest topic but can get very confusing
CHART OF ALL THE NUMBER GROUPS;
– Natural Numbers {N} ; all positive, whole numbers, but not including zero, no negative numbers
– Whole Numbers {W} ; all positive, whole numbers, including zero, no negative numbers
– Integers {I} ; positive and negative, whole numbers, including zero,
– Rational {Q} ; can be written as a fraction ex; 5/1 = 5
– Irrational {Q} ; CANNOT be written as a fraction ex; 17/4
– Real {R} ; All rational & irrational numbers
