PS:

PLS MARK ME AS BRAINLEST

Step-by-step explanation:

Use the systematic new AC Method to factor trinomials (Socratic Search)

y

=3x2+7x−6

=3(x + p)(x + q)

Converted trinomial:

y'

=x^2+7x−18

= (x + p')(x + q').

p' and q' have opposite signs.

Factor pairs of (ac = -18) --> (-2, 9). This sum is 7 = b. Then p' = -2 and q' = 9. Therefore,

p ='p/a

= -2/3

and

q ='q/a

=9/3

=3.

Factored form: y = 3(x - 2/3)(x + 3) = (3x - 2)(x + 3)

Answer:

{8, 10, 12, 18}

Step-by-step explanation:

The domain of a given relation are all the x-values or inputs.

Locate the inputs:

{(8, 4), (10, –3), (12, 0), (18, –1)}

The domain in this given relation is {8, 10, 12, 18}.

Answer:

2^x

Step-by-step explanation:

Since we are needing to show how this is written, x is a power so it will be written small and will go to the upper right corner of the 2 :)

When you see a number like this, we are multiplying 2 by intself x times :)

Sorry i dont really know how to do that just a guess

Dilating the triangle TRW would change the size of the triangle

The ordered pair that best represents the location of point R′ is (nRx,nRy)

The coordinates of the point R would be represented as:

R = (Rx,Ry)

The scale of dilation (k) is given as:

k = n

Given that the center of dilation is the origin, the location of point R' would be:

R' =R * k

So, we have:

R' = (Rx,Ry) * n

Evaluate the product

R' = (nRx,nRy)

Hence, the ordered pair that best represents the location of point R′ is (nRx,nRy)

Step-by-step explanation:

We know the ratio of map distance to actual distance is 1 cm : 15 km

Multiplying both sides by 11, we have 11 cm : 165 km

Answer:

C. between 150 and 200 miles

Step-by-step explanation:

To find the average, we need to divide 732 by 4 to get 183. Since 183 is between the numbers 150 and 200, C is the answer to the question.

Answer:

1/64

Step-by-step explanation:

A negative exponent in essence brings your 2^6 value under 1. So your problem would now look like 1/(2^6). From there it is easy simplifying, knowing hat 2^6 = 64. So your answer turns out to be 1/64.

2 to the power minus 6 as a fraction would be equal to 1/64

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A negative exponent in essence brings  2^6 value under 1.

So  1/(2^6).

From there it is easy simplifying, knowing that;

2^6 = 64.

Therefore, the answer turns out to be 1/64.

2 to the power minus 6 as a fraction would be equal to 1/64

Answer:

The system of equations has no solution.

Step-by-step explanation:

set them equal to eachother. 3x+9=3x-4

Subtract 3x from both sides, giving you 9=-4, which is an equation that is not true because 9 does not equal negative 4. Therefore, there is no solution to this system.

Answer: $12.875

Step-by-step explanation:

Emma works two jobs. At her day job, she earns $8/hour and works for 3 hours. Total amount earned will be:

= $8 × 3 = $24

She works her evening job for 9 hours and earns $14.50/hour. Total amount earned will be:

= $14.50 × 9 = $130.5

Total amount earned will now be:

= $24 + $130.5

= $154.5

Since she works a total of: 3 hours + 9 hours = 12 hours per day, the amount made on average per hour will be:

= $154.5/12

= $12.875

Answer:

A.  m∠A = 45°

Step-by-step explanation:

Vertical angle theorem:  opposite angles are congruent

⇒ 3x = x + 30

⇒ 2x = 30

⇒ x = 15

As m∠A = 3x

⇒ m∠A = 3 × 15 = 45°

Opposite angles are equal

[tex]\\ \rm{:}\dashrightarrow 3x=x+30[/tex]

[tex]\\ \rm{:}\dashrightarrow 2x=30[/tex]

[tex]\\ \rm{:}\dashrightarrow x=15[/tex]

So

Step-by-step explanation:

2x + y = 2         subtract 2x from both sides

2x - 2x + y = 2 - 2x

y = -2x + 2

(m = -2, b = 2)

-3x + y = 4        add 3x to both sides

-3x + 3x + y = 4 + 3x

y = 3x + 4

(m = 3, b = 4)

The exponential function is given by y = 13000(0.85)ˣ, the amount of rats in 3 years is 7984

An exponential function is in the form:

y = abˣ

Where y,x are variables, a is the initial value of y and b is the multiplication factor.

Let y represent the population of the chicken after x year.

The initial population of 13000 rats, hence a = 13000

The rat population declining by 15% every year. b = 1 - 0.15 = 0.85

The exponential function is given by y = 13000(0.85)ˣ

In 3 years; y = 13000(0.85)³ = 7984

The exponential function is given by y = 13000(0.85)ˣ, the amount of rats in 3 years is 7984

Answer:

33.5%

Step-by-step explanation:

First you need to subtract the amount he bought the ticket from the amount he sold it.

$121 ₋ $88

=$33

After that you need to divide the answer you got by the original amount of the ticket multiply it  by 100.

33 ÷ 88 × 100

=37.5%

Answer:

[tex]y=\dfrac12x+9[/tex]

Step-by-step explanation:

The product of the slopes of perpendicular lines is -1

Given the slope of Line L is -2, this means that the slope of Line M will be:

[tex]\dfrac{-1}{-2}=\dfrac12[/tex]

[tex]\sf as \ \dfrac12 \cdot -2 = -1[/tex]

If Line M intersects the y-axis at (0, 9) then its y-intercept is 9.

Slope-intercept of a linear equation: [tex]y = mx + c[/tex]

(where m is the slope and c is the y-intercept)

Therefore, the equation for Line M is:

[tex]y=\dfrac12x+9[/tex]
