Week 14 Blog post

This week in math, we learning how to simplify radical expressions. If the top the same term as the bottom they can cancel each other out. Our first step is to simplify the expression and then you find what the variable cannot equal to, sometimes there are more than 1 solution. In the example below:

I first found what the X value cannot equal to, so it was 0,9. Next i found all like terms and cancelled each other out X, (X-3). This left me with 24/18x which i could then simplify to 4/3x.

Week 13 Blog Post

This week is math, we learned how to graph absolute values, meaning the graph cannot cross the X axis to become negative. How this works, is the point it normally crosses to the negative side, reflects going the opposite direction using the same pattern, let’s say we were using 3x+2, when it reaches the point where it’s supposed to cross it goes up 3 then to the other way 2. If we were going up 3 over 2 to the right the reflected side would be up 3 over 2 to the left. We also learned how to do this with parabolas but instead of one line, it will be the vertex that will be reflected, the same rules also apply, the X intercept is like an invisible wall which will not let the line/ parabola cross to become a negative.

In the first picture, this graph represents the graph of x2+3x-5 and |x2+3x-5|. The green line represents the parabola if it were to be just graphed, no absolute values; we can see that it crosses the X intercept making it negative. In the orange lines, we can see the vertex is reflected, because the invisible wall reflected it back to a positive, having the same vertex but positive.

In the second picture, the orange line represents the normal value where it goes into negative 3x+2, and the blue line represents the absolute value version, where it’s reflected, which the equation is|3x+2|. This represents the absolute value, where it reflects right before it crosses the X intercept using the same pattern as the normal version but going up 3 to the left 2…

Math week 12 Blog Post -Edited

This week in math week 12, we re-learned how to substitute y=mx+b but with a quadratic, to solve the quadratic version, you must have 2 quadratic equations. The first step in this is to make sure Y or X is isolated generally i like to isolate Y,  and make sure they have no coefficients, and that you have an x2 to make sure you have a quadratic equation. Now that you have that you have one of the variables isolated, you use that solution and put it into the other solution wherever you see the variable you isolated on the other solution. Next you want to subtract one end to another making one side equal to 0 (Generally you subtract the soltion without x2)          

Now you want to find the 0’s, because this will allow you to find the y axis. Finding the 0’s will help you complete the equation. Once you find the 2 zero’s, you replace it in any of the equations finding the y axis but it has to be the same equation.

Math Blog post Week 11

This week in math, we learned how to graph inequalities and systems of equations. This week, we combined our last 2 units and made it into one (Solving Quadratics, and Graphing inequalities and systems). We learned that if the equal sign has a line on the bottom which means equal that it will have a solid line when graphing. $slatex y\le4x+5$. Knowing this we can add a point to check which part to shade in, in this case i used (-2,1)

-2>4(1)+5 =      -2> 8+5

This shows us that we need to shade the bottom side of the graph, because the test points for this solution was not true.

Gilligan’s point can be seen in children’s free play. When boys are confronted with a conflict involving fairness they tend to argue it out or take their ball and go home. On the other hand, girls faced with conflict over fairness will try to resolve the issue through compromise. But if compromise fails, girls will generally change the activity rather than disband the group (Cyrus, 1993).

Math blog post Week 10// Self assessment – Critical thinking

This week, i went over 3 things that i forgot how to do. The first one i did was rationalizing radicals. I knew the general idea of this, but i forgot how you have to multiply the conjugate making it a zero pair rather than multiplying by the same thing. For my second one, i did arithmetic sequences, i didn’t forget how to do it, it was just a memory refresher. And for the last one, i did solving discriminant which tells me how many roots i have and this was confusing for me on the test, because i would divide it by 2a.

Math blog post week 9

This week in math, I learned how to find the X intercepts in the standard form. I learned this late, but i still learned it in week 9. So to find the X intercepts we have to go back to our last chapter Solving for quadradics. First you would isolate to make X by itself so i subtracted by 1, then after that i sqaure rooted everything to get rid of the brackets, the from there i added 2 to the other side make it 2+/- square root of 1.

Math blog post week 8

This week in math, we learned how to use the X intercepts to find the Line of symmetry. To find the LOS, you take both X intercepts and you add them together then divide by 2. So in the picture below, the X intercepts are -4,0 and 2,0. 2-4/2= -1. Thats the line of symmetry.

Math blog post week 7

This week in Pre calc 11, I learned how to graph the vertex. I learned that when you are given the standard form, you can graph the vertex. In the brackets, you have the X value but a cool thing is that whatever number is in there, you change the sybol. So if it is -3 it really means +3. and the number right outside the brackets is the Y value; so given y=a(x-3)+3, we can tell that we need to graph (3,3) and that is our vertex.
