11. Factoring and solving equations

- A. Factor-

1. Factor 3x2 + 6x if possible.

Look for monomial (single-term) factors first; 3 is a factor of both 3x2

and 6x and so is x . Factor them out to get

3x2 + 6x = 3(x2 + 2x1 = 3x(x+ 2) .

2. Factor x2 + x - 6 if possible.

Here we have no common monomial factors. To get the x2 term

we'll have the form (x +-)(x +-) . Since

(x+A)(x+B) = x2 + (A+B)x + AB ,

we need two numbers A and B whose sum is 1 and whose product is

-6 . Integer possibilities that will give a product of -6 are

-6 and 1, 6 and -1, -3 and 2, 3 and -2.

The only pair whose sum is 1 is (3 and -2) , so the factorization is

x2 + x - 6 = (x+3)(x-2) .

3. Factor 4x2 - 3x - 10 if possible.

Because of the 4x2 term the factored form wli be either

(4x+A)(x +B) or (2x+A)(2x+B) . Because of the -10 the integer possi-

bilities for the pair A, B are

10 and -1 , -10 and 1 , 5 and -2 . -5 and 2 , plus each of

these in reversed order.

Check the various possibilities by trial and error. It may help to write

out the expansions

(4x + A)(x+ B) = 4x2 + (4B+A)x + A8

1 trying to get -3 here

(2x+A)(2x+B) = 4x2 + (2B+ 2A)x + AB

Trial and error gives the factorization 4x2 - 3x - 10 - (4x+5)(x- 2) .

4. Difference of two squares. Since (A + B)(A - B) = - B~ , any

expression of the form A' - B' can be factored. Note that A and B

might be anything at all.

Examples: 9x2 - 16 = (3x1' - 4' = (3x +4)(3x - 4)

x2 - 29 = x2 - (my)* = (x+ JTy)(x- my)

For any of the above examples one could also use the

Step-by-step explanation:

Original height is the initial value, burn down rate is 0.5 inches per hour

This would be represented by a function:

Ordered pairs:

If the rate at which the candle burned was 0.45 inches per hour instead of 0.5 inches per hour, the relation would still be a function. The output values would have same difference of 0.45 inches and the function would be:

The coordinates are  (-1, 10).

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions. Since it is just moving of the shape from one place to other, there is no change in the shape.

Translation is one of the transformations in math. When a shape has been transformed, the original shape is called the preimage and the vertices are usually labeled using uppercase letters (Example: ABCD). The translated shape is called the image and the vertices are labeled using uppercase letters with a “prime” next to each (Example: A′B′C′D′, and is pronounced “A-prime, B-prime, C-prime, D-prime”).

Given:

the point is (-8, 3) whose image point is (-5, 2)

The difference between the coordinates of the image and the coordinates of the original is the same for both points.

 X - (-6, 5) = (4, 4) -(-1, -1)

 X = (4, 4) -(-1, -1) +(-6, 5) = (4+1-6, 4+1+5)

 X = (-1, 10)

Hence, the point is (-1, 10)

Answer:

C

Step-by-step explanation:

The secant- secant angle SPR is half the difference of the intercepted arcs, that is

55° = [tex]\frac{1}{2}[/tex] (RS - QT ) ← multiply both sides by 2

110° = RS - QT = RS - 50° ( add 50° to both sides )

160° = RS → C

Step-by-step explanation:

Area of rectangle = length x width

Area of square = side x side

Given: Dimension of rectangular wall: 8 feet high and 30 feet wide

Area of rectangular wall = 8 feet x 30 feet = 240 ft²

Height of square wall = 9 feet

Area of square wall = 9 x  9 ft² = 81 ft²

Total area need to paint = 240 ft²+  81 ft² = 321 ft² > 250 ft.²

Answer:

Senior citizen ticket = $4, student ticket = $6

Step-by-step explanation:

To do this, form a system of equations where x = the cost for a senior citizen ticket and y = the cost for a student ticket.

Since 12 senior citizen tickets and 14 students tickets cost $132, you get

12x + 14y = 132.

Since 12 senior citizen tickets and 10 students tickets cost $108, you get

12x + 10y = 108.

You can subtract those two equations, so

12x + 14y = 132

-(12x + 10y = 108)

and you get

4y = 24

divide both sides by 4

y = 6

substituting into the equation 12x + 10y = 108,

12x + 10(6) = 108

12x + 60 = 108

subtract 60 from both sides

12x = 48

divide both sides by 12

x = 4

A senior citizen ticket costs $4 and a student ticket costs $6.

Answer:

790cm

Step-by-step explanation:

Briana buys a reel of thread for sewing. There are 10 m of thread on the real. Her brother in grade 4 used 210 cm. How much is left on the reel in centimeters?

1m = 100cm

10m = x

x = 10 × 100cm

x = 1000cm

The total number of thread on the reel = 1000cm

The amount of thread left on the reel is calculated as:

The total number of thread on the reel - The amount of thread on the reel that was used.

= 1000cm - 210cm

= 790cm

Answer:

m(∠CAG) = 35°

Step-by-step explanation:

From the figure attached,

Apply Pythagoras theorem in ΔCAG,

Length of AC = [tex]\sqrt{(27)^2+(36)^2}[/tex]

                      = [tex]\sqrt{729+1296}[/tex]

                      = [tex]\sqrt{2025}[/tex]

                      = 45

Now find the tangent of the given angle CAG,

tan(∠CAG) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

                  = [tex]\frac{CG}{AC}[/tex]

m(∠CAG) = [tex]\text{tan}^{-1}(\frac{31.5}{45} )[/tex]

                = [tex]\text{tan}^{-1}(0.7)[/tex]

                = 34.992°

                 ≈ 35°
