hii ok so i have another homework question..

- use the graphs to determine the equation of the qudratic functions in standard form.

its a parabola opening down, the roots are at -4 and 7. and they give me another point which is (6,32). there is no vertex point given.

i started by doing this :

a(x+4)(x-7) =0
a(x^2-7x+4x-28)=0
a(x^2-3x-28)=0

then i plugged in the points to find a.

32=0(36-18-28)
32=(a)(-10)

NOW, here's where the problem is..

a is supposed to equal -3.2. (the answer is -3.2x^2+9.6+89.6).

but how is 32*10 = -3.2??? :S :S

--------------

also, how do you find the equation when its a parabola opening up. they only give you the vertex (3,5) and one point on the graph which is (9,-35) ??

please include the steps in your answer plz!! :) thx!

There's a cage with 10 pets in it - dogs and cats. There are 56 biscuits to be fed to them. Each dog eats 6 biscuits and each cats eats 5 biscuits. How many of each pet are there?

The algebraic equation to this problem is

6D + 5C = 56
6(10 - C) + 5C = 56
60 - 6C + 5C = 56
60 - C = 56
- C = -4
C = 4

but where did the 6(10-C) come from? Also, how did you came to having -C=-4?

A) Expression
B) Linear equation
C) Equation which is not linear

2)Solve. 11x + 6 = 10x

3)Solve. 4(7x + 10) = 3(9x – 5) + 20

4)Find the mean.
2, 3, 8, 9, 13


5) Solve. 12 – 4x = 20

6) Solve. 6x + 4(3x – 2) = 6x + 2

Suppose M is the center of a circle and A and B two points on the circle circumference. (AB is not a diameter)

The tangent lines on the circle from A and B intersect in C.

CM intersects with the circle in D.

The tangent line of circle from D, intersects with AC and BC in E and F respectively.
***************************
Please show that the area of ADBM is the geometric mean of the areas of ABM and ACBM.
