Topic: **Steps of a problem solving****Question:**
8.) Solve the system of equations.
4x+5y=3
2x+y=0
9.) A possible step toward solving these equations by addition could be :
4y-6x=11
-8x-4y=13
10.) Given the coordinate points A(2,4), C(3,6), and F(4,8), which equation proves that point C lies on the line AF?
11.) From this trinomial you can deduce that:
x to the second power - 6x + 9=0
12.) Factor the polynomial completely.
49s+7rs - 21 - 3r
13.) Factor completely.
12x to the second Power + 13x+ 3

8.) Solve the system of equations. 4x+5y=3 2x+y=0 --> x=-.5; y= 1; 9.) A possible step toward solving these equations by addition could be : 4y-6x=11 -8x-4y=13 --> -14x = 24 10.) Given the coordinate points A(2,4), C(3,6), and F(4,8), which equation proves that point C lies on the line AF? --> d(A,C)+d(C,F)=d(A,F) 11.) From this trinomial you can deduce that: x to the second power - 6x + 9=0 --> x = 3 12.) Factor the polynomial completely. --> 49s+7rs - 21 - 3r = 7s(7+r) - 3(7+r) = (7s-3)(7+r) 13.) Factor completely. 12x^2 +13x +3 = (4x+3)(3x+1)

Just don't tweet about her.Also tell her that she is invading your privacy and tries to cause problems when you have nothing to hide.Your mom is the one who should decide if you are doing anything wrong.

My dad is really overprotective and nosy too! Least I know i'm not the only teen with this problem. What I would do is bring your laptop upstairs and keep it away so she dosent know where you keep it. If you have google chrome, there is this window called the 'Incognito window' which doesn't save your history which is stored on the laptop/computer. If you dont have chrome, or have another browser, delete the cookies and history. About the facebook and twitter problem, i would make up 2 accounts for each, and they would have their own individual passwords which nobody but you know. On the new accounts, block any family relatives and keep the ones that you trust (its up to you) then add all your friends on your new account. Then she wont see what you tweet and post on facebook. About when a guy posts on your picture, all parents are bound to be nosy about guys posting on your wall/photos...etc. Don't worry about it because I am sure that your mum will understand that it is just a friend commenting on your photo:) -imogen ;D

a million. gas weights 0.69g/cm^3. If a automobile has 40 L gas tank, how plenty greater advantageous weight, in kilograms, is the automobile pulling while the gas tank is completed? by way of fact that a million Liter is a million,000 cm^3, One Liter of gas weights 690 grams or 0.sixty 9 kilograms. 40 L is 27.6 kilograms 2. A race automobile reaches a velocity of one hundred sixty miles in keeping with hour. what's the fee of velocity in keeping with minute? one hundred sixty miles in keeping with hour x ( one hour/60 minutes) = 2.sixty seven miles in keeping with minute 3. A 12 foot ladder is 12 foot x (12 inches in keeping with foot) = one hundred forty four inches. A 12 foot ladder is in simple terms too short.

Well its a maths illusion sequence, For instance even with two rectangles side by side your eyes see two rectangles, but there are three. If you take the dicecting middle line away it make one big rectangle aso, therefore three, Three rectangles next to each other is three small two medium and one large, by taking one disecting line away at time. Therefor 3=6. So if 2=3 and 3=6, Then 4 will be 10 and so on..... Now do the math. Regards.

2x + 2y = 20 utilising the simultaneous technique 2x - 2y = 4 ____________ 4x = 24 ( divide by utilising 4) x = 6 replace x in one among the two equations 2x + 2y = 20 2 (6) + 2y = 20 12 +2y = 20 2y = 20 - 12 2y = 8 (divide by utilising 2) y = 4 answer : X = 6 , Y = 4
