Answer:
Step-by-step explanation:
1) Sum = - 9
Product = -36
Factors = -12 , 3 {-12 + 3 = -9 & -12*3 = -36}
3a² - 9a - 12 = 3a² + 3a - 12a - 12
=3a(a + 1) - 12(a + 1)
= (a + 1) (3a - 12)
2) 4a² + 38a - 20 = 4a² + 40a - 2a - 20
=4a(a + 10) - 2(a + 10)
=(a + 10)(4a - 2)
3) 11a² + 30a - 9 = 11a² + 33a - 3a - 9
= 11a(a + 3) - 3(a + 3)
=(a + 3)(11a - 3)

6) y = 2x² + 6x - 80
1) y = 2*x² + 2*3x - 2*40
y = 2 [ x² + 3x - 40]
2) Sum = 3
Product = -40
Factors = (-5) ; 8 {-5 +8 = 3 ; (-5)*8 = -40}
y = 2 [ x² + 8x - 5x - 40]
= 2 [ x(x + 8) - 5(x + 8) ]
= 2 [ (x +8) (x - 5)]
y = 2(x +8)(x -5)
b) y = 0
2(x + 8)(X - 5) = 0
x + 8 = 0 ; x - 5 = 0
x = -8 ; x = 5
(-8) ; 5 are the zeros.

O B) x^2 + y^2 + 12x - 20y + 55 = 0
-
O C) x^2 + y^2 - 12x+ 20y + 127 = 0
-
O D) x^2 + y^2 – 20x – 16y + 155 = 0
Answers
Answer:
C.
Step-by-step explanation:
WE need to convert the given equations into the standard form
(x - a)^2 + (y - b)^2 = r^2 where r = the radius.
x^2 + y^2 + 12x - 20y+ 132 = 0
(x + 6)^2 - 36 + (y - 10)^2 - 100 = -132
(x + 6)^2 + (y - 10)^2 = -132 + 36 + 100 = 4
giving a radius of 2
x^2 + y^2 + 12x - 20y + 55 = 0
will give a right hand side of -55 + 36 + 100 = 81 giving radius 9.
x^2 + y^2 - 12x+ 20y + 127 = 0
- gives right hand side of -127 + 36 + 100 = 9 giving a radius of 3.

The answer is C I hope this helps

Answers
Answer: x = -11
Step-by-step explanation:
Expand the expression (distributive property): 3 - 9x = -8x + 14
// subtract 14 from both sides = -11
// add 9x on both sides = x
Simplify: x = -11
Answer:
[tex]x=-11[/tex]
Step-by-step explanation:
1) Rearrange Terms
[tex]3(-3x+1)=2(-4x+7)[/tex]
2) Distribute
[tex]-9x+3=2(-4x+7)[/tex]
3) Distribute
[tex]-9x+3=-8x+14[/tex]
4) Subtract 3 from both sides of the equation
[tex]-9x+3-3=-8x+14-3[/tex]
5) Simplify
A. Subtract the numbers
[tex]-9x=-8x+14-3[/tex]
B. Subtract the numbers
[tex]-9x=-8x+11[/tex]
6) Add 8x to both sides of the equation
[tex]-9x+8x=-8x+11+8x[/tex]
7) Simplify
A. Combine like terms
[tex]-x=-8x+11+8x[/tex]
B. Combine like terms
[tex]-x=11[/tex]
8) Divide both sides of the equation by the same term
[tex]\frac{-x}{-1} =\frac{11}{-1}[/tex]
9) Simplify
A. Cancel terms that are in both the numerator and denominator
[tex]x=\frac{11}{-1}[/tex]
B. Divide the numbers
[tex]x=-11[/tex]

Two angles are supplementary. One of them is 18 more than 6 times the other. How large is the larger angle?
Answers
Answer:
im think its 24
Step-by-step explanation:
18+6
Explanation:
x = smaller angle
6x + 18 = larger angle
Supplementary angles add up to 180 degrees.
x + 6x + 18 = 180
7x + 18 = 180
7x = 162
x = 23.1429
x = 23.14 degrees
X can be substituted into the other expression to find the larger angle.
6(23.14) + 18
138.84 + 18
156.84 degrees
To check, add the two angles to make sure the sum is 180 degrees.
23.14 + 156.84 = 180
179.98 = 180

Jorge has a standard deck of 52 cards and a six-sided number cube. What is the probability that he will draw a diamond from the deck of cards and roll a number greater than two? Write your answer as a simplified
Answers
The probability that Jorge draw a diamond from the deck of cards and roll a number greater than two is 2/39
Probability is the like likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
If Jorge has a standard deck of 52 cards, the total outcome is 6
If Jorge draw a diamond card, the probability that he will draw a diamond card is 4/52 = 1/13
For a six-sided cube, the total outcome is 6. If he rolls a number greater than two, the expected outcome will be 4
The probability that he rolls a number greater than 2 is 4/6 = 2/3
The probability that Jorge draw a diamond from the deck of cards and roll a number greater than two is 1/13 * 2/3 = 2/39
