Answer:

-91x² + 5x³ - 56x -15 = 0

Step-by-step explanation:

x² + 3x³ - 2x + 9 = 24 + 54x + 92x² - 2x³

x² + 3x³ - 2x + 9 - 92x² = 24 + 54x + 92x² - 2x³ - 92x²

-91x² + 3x³ - 2x + 9 + 2x³ = 24 + 54x -2x³ + 2x³

-91x² + 5x³ - 2x + 9 - 54x = 24 + 54x - 54x

-91x² + 5x³ - 56x + 9 - 24 = 24 - 24

-91x² + 5x³ - 56x -15 = 0

Answer:

$2.10

Step-by-step explanation:

first we want to find for one kg. one kg is $0.30.

Multiply that by 7 and you get $2.10

Answer:

$23.10

Step-by-step explanation:

8.25 ÷ 2.5 = 3.3

7 x 3.3 = 23.10

you have to find out how much money you pay per kg

you pay $3.30 per kg

therefore you have to multiply the kg (7) by the price (3.30) and that's why you get $23.10

Step-by-step explanation:

Answer:

Step-by-step explanation:

x + y = 1           -------------------(I)

5x + 3y = -3 -----------------(II)

Multiply (I) by (-5)    -5x - 5y = -5

                               5x + 3y = -3          {Now add}

                                     -2y = -8  

                                        y = -8/-2

                                        y = 4

Plugin y = 4 in equation (I)

x + 4 = 1

    x   = 1 -4

    x = -3

Solution: (-3, 4)

Answer:

Step-by-step explanation:

a₁ = -3 = (-1)¹×3

a₂ = 6 = (-1)²×2×3

a₃ = -28 = (-1)³×2²×7

a₄ = 72 = (-1)⁴×2³×3²

a₅ = -360 = (-1)⁵×2³×3²×5

a₆ = 2160 = (-1)⁶×2⁴×3³×5

That's as far as I got. I can predict that a₇ is a multiple of -32 and a₈ is a multiple of 64, but I don't see the pattern with the other factors.

Answer:

Step-by-step explanation:

When x = -4, y = 2(-4)+2 = -6.

When x = -3, y = 2(-3)+2 = -4.

Fill in the other values of y the same way.

Answer:

Explanation:

y = 2(-4) + 2

y = -6

y = 2(-3) + 2

y = -4

y = 2(-2) + 2

y = -2

y = 2(-1) + 2

y = 0

y = 2(0) + 2

y = 2

y = 2(1) + 2

y = 4

y = 2(2) + 2

y = 6

Reading through the problem, we have "15 is",

that's "15 =", 15%, 15/100, "of", times, "what number", x.

So our equation reads 15 = 15/100 · x.

Step 1: Define

Step 2: Evaluate

A function assigns values. The rectangular equation can be described as cubic.

A function assigns the value of each element of one set to the other specific element of another set.

As the function of x and y is given, therefore, if we eliminate t from both the function we will get,

[tex]x=t^{\frac12}\\\\x=\sqrt t\\\\x^2=t[/tex]

Now, substitute the value of t in the function of y,

[tex]y= t-4\\y=x^2-4[/tex]

Further, the rectangular equation can be written as,

[tex]\text{Rectangular Equation} = x \times y[/tex]

                                   [tex]= x \times (x^2-4)\\\\= x^3-4x[/tex]

Thus, the rectangular equation can be described as cubic.

Answer:

Letter B

Step-by-step explanation:

Answer:

Step-by-step explanation:

→ Given angles of triangle = 45° + 45° + 90° {from <3>}

→ x = y {because of <1>}

→ H² = P² + B² (Pythagoras Theorem) {from <2>}

→ (12)² = x² + y²

→ 144 = x² + x² [x = y]

→ 144 = 2x²

→ 144/2 = x²

→ 72 = x²

→ √(72) = x

→ 6√2 = x

→ x = y

so,

x = 6√2 = y

Answer: See explanation

Step-by-step explanation:

Ally served 40% of the customers

Benny served 27%

Percentage served by Charli will be:

= 100% - (40% + 27%)

= 100% - 67%

= 33%

That night 60% of Ally's customers ordered pie, while 40% did not. Of Benny's customers, 20% ordered pie.

The percent that did not will be:

= 100% - 20%

= 80%
