-2x + 9y=-41 and -2x -5y =1

The y intercept of the line passes through the point (32, 22) and (48, 17) is 32

An equation is an expression that uses mathematical operations to show the relationship between numbers and variables. Types of equations are linear, quadratic, cubic and so on.

The standard form of a linear equation is:

Ax + By = C

Where A, B and C are constants

The slope intercept form of a linear equation is:

y = mx + b

Where m is the slope and b is the y intercept

The slope of the line passing through points (x₁, y₁) and (x₂, y₂) is:

m = (y₂ - y₁) / (x₂ - x₁)

The table shows that the line passes through the point (32, 22) and (48, 17). Hence:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\substituting:\\\\y-22=\frac{17-22}{48-32} (x-32)\\\\y=-\frac{5}{16}x+32[/tex]

Answer:

x = 11

y = 21

Step-by-step explanation:

1. y = 2x-1

2. 6x-2y = 24

lets plug in the value of y from the first equation, into the second

6x - 2(2x-1) = 24

6x - 4x + 2 = 24

2x + 2 = 24

2x = 22

x = 11

lets plug in x to the first equation to find y

y = 2(11)-1

y = 22-1

y = 21

Answer:

x = 11

y = 21

Step-by-step explanation:

y = 2x - 1;

6x - 2y = 24

y = 2x - 1

3x - y = 12

y = 2x - 1

3x - (2x - 1) = 12

y = 2x - 1

x + 1 = 12

y = 2x - 1

x = 11

y = 2(11) - 1

x = 11

y = 21

x = 11

The solution is Option D.

The sum of the infinite geometric progression is S = ( 64/7 )

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the sum of the geometric progression be represented as S

Now , the equation will be

S = 16 , -12 , 9 , -( 27/4 ) ...

The sum of the infinite GP is S = a / ( 1 - r ) , where r is the common ratio

Substituting the values in the equation , we get

a₁ = 16

a₂ = -12

So , the common ratio r = a₂ / a₁

The common ratio r = -3/4

Substituting the values in the equation , we get

The sum of the infinite GP is S = a / ( 1 - r )

The sum of the infinite GP is S = 16 / ( 1 - ( -3/4 ) )

The sum of the infinite GP is S = 16 / ( 1 + 3/4 )

The sum of the infinite GP is S = 16 / ( 7/4 )

The sum of the infinite GP is S = ( 16 x 4 ) / 7

The sum of the infinite GP is S = ( 64/7 )

Hence , the sum of GP is ( 64/7 )

Let's call the sales tax rate as t (in decimal form).

The cost of a $10 sweater with the sales tax included is $10 + $10 * t = $10.90.

We can set up an equation to solve for t:

$10 * t = $0.90

Dividing both sides by $10:

t = 0.09

So the sales tax rate is 0.09, which is equivalent to 9%.

Step-by-step explanation:

The value of x is 30 degrees as it is a complimentary angle. When two angles' measurements add up to 90 degrees, they are said to be complimentary. When two angles' measures sum up to 180 degrees, they are said to be supplementary.

Complementary angles are two angles with a combined angle of 90 degrees, whereas supplementary angles have a combined angle of 180 degrees.

Reflex angles are those that are larger than 180 degrees and less than 360 degrees. So 270 degrees is a reflex angle.

Answer:

Step-by-step explanation:

In accordance with the Remainder theorem,  the given part means that the given polynomial has the roots of 1, -2 and 2.

So we write these three equations expressing this fact

   2A*1^4    - B*1^3    - C*1     - 16 = 0

   2A*(-2)^4 - B*(-2)^3 - C*(-2)  - 16 = 0

   2A*2^4    - B*2^3    - C*2     - 16 = 0

or

   2A -  B -  C = 16    (1)

  32A + 8B + 2C = 16    (2)

  32A - 8B - 2C = 16    (3)

Adding equations (2) and (3), you get

  64A           = 32,   which implies  A = 32%2F64 = 0.5.

Then from (1) and (2), substituting A = 0.5 there, you get

    B +  C = -15        (4)

   8B + 2C =   0        (5)

Expressing  B = -15 - C  from (4)  and substituting it to (5), you get

   8*(-15 -C) + 2C = 0,    or

   -120 - 8C +  2C = 0

        - 6C = 120

           C = - 20.

Then from equation (4),  B = -15 - (-20) = -15 + 20 = 5.

ANSWER.  A = 0.5;  B = 5,  C = -20.

We have three factors: (x-1),(x+2) and (x-2)

However, we have a quartic polynomial, since the degree (largest exponent) is 4

So we need a fourth factor. Let's call that x-p, for some real number p.

Let's expand out the following

(x-1)(x+2)(x-2)(x-p)

(x+2)(x-2)(x-1)(x-p)

(x^2-4)(x^2-px-x+p)

x^2(x^2-px-x+p)-4(x^2-px-x+p)

x^4-px^3-x^3+px^2-4x^2+4px+4x-4p

x^4+(-px^3-x^3)+(px^2-4x^2)+(4px+4x)-4p

x^4+(-p-1)x^3+(p-4)x^2+(4p+4)x-4p

Compare that result to 2Ax^4-Bx^3-Cx-16

Match up the corresponding terms, and we have the following equations

2Ax^4 = 1x^4 which leads to 2A = 1 and solves to A = 1/2 = 0.5

(-p-1)x^3 = -Bx^3 which leads -p-1 = -B and solves to B = p+1

(4p+4)x = -Cx which leads to 4p+4 = -C and solves to C = -4p-4

-4p = -16 which solves to p = 4

Use that value of p to find the other coefficients

B = p+1 = 4+1 = 5

C = -4p-4 = -4*4-4 = -20

The polynomial 2Ax^4-Bx^3-Cx-16 turns into x^4-5x^3+24x-16 after we plug in those A,B, and C values.

The polynomials that match with other equivalent expressions are :(a) → (iii), (b) → (ii), (c) → (iv), (d) → (i)

Consider the polynomials,

(a) 4x² + 18x                                (i) 2x(2x + 1)

(b) 4x² + 2x + 18x +9                   (ii) (2x + 1)(2x +9)

(c) (2x + 3)(2x + 3)                       (iii) 2x(2x + 9)    

(d) 4x² + 2x                                   (iv) 4x² + 12x + 9

Now,

Consider the polynomial 2x(2x + 1),

2x(2x + 1) = 2x(2x) + 2x(1)

2x(2x + 1) = 4x² + 2

Therefore, (d) is equal to (i).

Consider the polynomial 2x(2x + 9),

2x(2x + 9) = 2x(2x) + 2x(9)

2x(2x + 9) = 4x² + 18x

Therefore, (a) is equal to (iii).

Consider the polynomial (2x + 1)(2x +9) ,

(2x + 1)(2x +9)  = (2x)(2x) + (2x)(9) + (2x)(1) + 9

(2x + 1)(2x +9) = 4x² + 18x + 2x + 9

Therefore, (b) is equal to (ii).

Consider the polynomial (2x + 3)(2x + 3),

(2x + 3)(2x + 3) = (2x)(2x) + (2x)(3) + (3)(2x) + 9

(2x + 3)(2x + 3) = 4x² + 12x + 9

Therefore, (c) is equal to (iv).
