Answer:

[tex]16x {y}^{2} + 10xy \\ = 2xy(8y + 5) \\ 2xy = 0 \: or \: 8y + 5 = 0 \\ y = - \frac{5}{8} [/tex]

The equation that would be used to solve the function is (x+5)^2 = 17

Given the quadratic equation -x^2 + 10x -8 = 0

This can also be written as:

-x^2 + 10x -8  = 0

x^2 - 10x + 8 = 0

x^ 2- 10x  = -8

The coefficient of x is -10

Half of the coefficient of -10 = -10/2 = -5

Square the result = 5^2 = 25

Add 25 to both sides of the equation

x^2 - 10x + 25 = -8 + 25

x^2 - 10x + 25 = 17

(x+5)^2 = 17

Hence the equation that would be used to solve the function is (x+5)^2 = 17

Problem

3.2x-1.7x+5.5=10

Steps:

1.5x + 5.5 = 10

1.5x X 10 + 5.5 X 10 = 10 X 10

15x + 55 - 55 = 100 - 55

15x = 45

15x/15 = 45/15

x = 3

Therefore questions ones answer is x = 3

Problem

3/4x-1/4x+14=3

Steps:

3/4x - 1/4x + 14 = 3

3/4x - 1/4x + 14 - 14 = 3 - 14

3/4x - 1/4x = -11

3/4x X 4 - 1/4x X 4 = -11 X 4

2x = -44

2x/2 = -44/2

x = -22

Therefore question two's answer is x = -22

Problem

3(2x+1)+x=-39

Steps:

7x + 3 = -39

7x + 3 - 3 = -39 - 3

7x = -42

7x/7 = -42/7

x = -6

Therefore question three's answer is  x = -6

9*1000=9000

Answer:

9:30

Step-by-step explanation:

9:30 = 3:10

If we put a ratio into a fraction for better visual representation, we will see that 3:10 turns in 3/10. If we multiply both the numerator and denominator by 3, we will get 9/30. You can divide 3 from both sides of 9/30 and it will go back to 3/10.

tl:dr Multiply both sides of a ratio to get the equivalent ratio.

The two properties newton used to rewrite the expression are;

- Associative Property; Because it involves change of grouping of numbers in the expression.

- Distributive Property; Because it involves distribution of a number outside a bracket to numbers inside that same bracket.

- Associative Property

- Commutative Property

- Distributive Property

Let us define each of them;

1) Associative Property; This property in algebra is one that means that no

matter how we group the numbers, we will still get the same result. e.g.

x + (y + z) = (x + y) + z.

2) Commutative Property; This property means that we can change the

order of operation and still get the same answer. For example;

p × q × r = p × r × q

3) Distributive Property; This property means that multiplying the sum of

two or more which are in a bracket by a number outside the will be equal to

the answer gotten when we multiply each number in the bracket

individually by the number outside and then adding their respective

products together. For example; p(q + r) = (p * q) + (p * r)

Newton has the expression; (4 × 23) × 25

Since it is multiplication, he can use any of the three properties above but let us use the associative and distributive properties as they are most suited to this expression.

(4 × 23) × 25 = 4 × (23 × 25)

(4 × 23) × 25 = (25 × 4) + (25 × 23)

Answer:

x=131°

Step-by-step explanation:

180°-49°=131°

<x is corressoping to the the angle next to <49°, so if you were to move it up there, it would be a linear pair or supplmentary angles, which equal 180°.

Answer:

(0, e-1) or (0, 1.718) to the nearest thousandth.

Step-by-step explanation:

The y-intercept occurs when x = 0 so here we have:

y = e^(1 - 0) - 1

= e - 1

So the y-intercept is the point (0, e-1)

In the given diagram, the value of x is 40

From the question,

we are given that

∠ SRT = ∠STR, and m ∠SRT = 20,

Also, from the question

m ∠STU = 4x

To determine the value of x,

From the diagram,

We can observe that

∠STR + ∠STU = 180° (Sum of angles on a straight line)

Since ∠ SRT = ∠STR, and m ∠SRT = 20,

Then,

∠STR = 20

Then,

∠STR + ∠STU = 180° becomes

20 + 4x = 180

To solve this,

First, subtract 20 from both sides

20 - 20 + 4x = 180 - 20

Then,

4x = 160

∴ x = 160 ÷ 4

x = 40

Hence, the value of x is 40

Answer:

Step-by-step explanation:

We want to find a polynomial given that we know its roots and a point on the graph.

We will find the polynomial:

p(x) = (183/280)*(x - 1)*(x - 1)*(x + 2)*x

We know that for a polynomial with roots {x₁, x₂, ..., xₙ} and a leading coefficient a, we can write the polynomial equation as:

p(x) = a*(x - x₁)*(x - x₂)...*(x - xₙ)

Here we know that the roots are:

Then the roots are: {1, 1, 0, -2}

We can write the polynomial as:

p(x) = a*(x - 1)*(x - 1)(x - 0)*(x - (-2))

p(x) = a*(x - 1)*(x - 1)*(x + 2)*x

We also know that this polynomial goes through the point (5, 336).

This means that:

p(5) = 336

Then we can solve:

336 = a*(5 - 1)*(5 - 1)*(5 + 2)*5

336 = a*(4)*(4)*(7)*5

336 = a*560

366/560 = a = 183/280

Then the polynomial is:

p(x) = (183/280)*(x - 1)*(x - 1)*(x + 2)*x
