Answer:

C

Step-by-step explanation:

Answer:

x^2 - 2x - 15 = 0.

Step-by-step explanation:

x^2 - 2x - 3 = 0

(x - 3)(x + 1) = 0

So alpha and beta are -1 and 3.

So the roots of the required equation are 2(-1)-1 and 2(3) - 1

= -3, 5.

So the equation is

(x - 5)(x + 3) = 0

-that is x^2 - 2x - 15 = 0

Answer Hi! you would do 15.34- 5.75

so do 75-34 =  41 and then 15- 5 = 10 so your anwser is -10.41 MAKE SURE ITS NEGTIVE

Answer:

Equation is 4y = -3x + 12

Step-by-step explanation:

General equation of a line:

[tex]y = mx + c[/tex]

for the slope:

[tex]slope = \frac{y_{2} - y_{1} }{x _{2} - x_{1} } [/tex]

consider points: (4, 0) and (0, 3)

[tex]slope = \frac{3 - 0}{0 - 4} \\ \\ slope = - \frac{3}{4} [/tex]

for y-intercept, c :

[tex]y = mx + c[/tex]

consider point (0, 3):

[tex]3 = ( - \frac{3}{4} \times 0) + c \\ \\ c = 3 \\ c = 3[/tex]

Equation is:

[tex]y = - \frac{3}{4} x + 3 \\ \\ 4y = - 3x + 12[/tex]

Answer:

the addition property of equality

.the multiplication property of equality

Step-by-step explanation:

1/3x - 6 =11

Add 6 to each side using the addition property of equality

1/3x-6+6 = 11+6

1/3x = 17

Multiply each side by 3, using the multiplication property of equality

1/3x *3 = 17*3

x = 54

Answer:

C

Step-by-step explanation:

the typical form of line equation is

y = ax + b

a = the slope of the line (expressed as y/x ratio telling us how many units y changes when x changes a certain number of units).

b = the intercept on the y-axis (when x = 0).

we know, a = -4

and we use the point (x = -2, y = 1) to get b

y = -4x + b

1 = -4×-2 + b = 8 + b

b = -7

=>

y = -4x - 7

only the points of option C are all fulfilling this equation.

e.g. x = 0, y = -7

-7 = -4×0 - 7 = -7, true, -7 = -7

and so on.

Answer:

x = -16

Step-by-step explanation:

given:

[tex]h(x) = -2x - 4[/tex]

solve for x, when:

[tex]h(x) = 6[/tex]

~~~~~~~~~~~~

➡️ [tex] x = -2(6) - 4 [/tex]

➡️ [tex] x = -12 - 4[/tex]

➡️ [tex] x = -16 [/tex]

The solution of x when the function h ( x ) = 6 is x = -5

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as h ( x )

Now , the value of h ( x ) is given by

h ( x ) = -2x - 4   be equation (1)

On simplifying the function rule , we get

when h ( x ) = 6

Substitute the value of h ( x ) = 6 , we get

6 = -2x - 4

Adding 4 on both sides , we get

-2x = 10

Divide by -2 on both sides , we get

x = 10 / -2

x = -5

Therefore , the value of x is -5

Hence , the equation is x = -5

Answer:

k = 5/6

Step-by-step explanation:

The √ can be rewrite as a power, and this power is 1/2

So √a = a^1/2, and it is multiplying a, so we add the powers: a¹•a^1/2 = a^(1+1/2) = a^3/2

And the ³√ can be rewrite as the power 1/3, but the a inside the ³√ is to the power of 2, so we can rewrite it like this: (a²)^1/3

And to evaluate this we have to multiply the powers, so we will have: a^2/3

Now we have this fraction:

[tex] \frac{ {a}^{ \frac{3}{2} } }{ {a}^{ \frac{2}{3} } } [/tex]

A fraction with powers in the same base can be rewrite like a subtraction of the powers, so let's do that:

[tex] \frac{ {a}^{ \frac{3}{2} } }{ {a}^{ \frac{2}{3} } } = {a}^{ \frac{3}{2} - \frac{2}{3} } = {a}^{ \frac{5}{6} } [/tex]

Hey there! I'm happy to help!

Imagine the line that is created when you connect the two points (the distance between the two points).

You can create a right triangle where this distance is the hypotenuse where the two legs are the change in x and y. So, if you take those changes in x and y, you can use the Pythagorean Theorem (a²+b²=c²) to find the distance between the two points, which is the hypotenuse.

Our change in x is 9 because 9-0 is 9.

We square it

9²=81

Our change in y is 5 as -1-(-6) or -1+6 is 5.

5²=25

We add these.

81+25=106

We square root and round to the nearest tenth.

√106≈10.3

So, our distance is 10.3.

This Pythagorean Theorem method actually gives us a formula called the distance formula that you can use to find the distance between points.

Answer:

BC = 22

Step-by-step explanation:

BD = 67

Bc = 3x - 2

CD = 4x + 13

BC + CD = BD (Given)

3x - 2 + 4x + 13 = 67

3x + 4x -2 + 13 = 67

7x + 11 = 67

7x = 67 - 11

7x = 56

x = 56 ÷ 7

x = 8

now instead of x put 8

Bc = 3x - 2

BC = 3(8) -2

BC = 24 -2

BC = 22

===========================================================

Explanation:

Hakim and Aziz have savings in the ratio 3:5. This means that Hakim has 3x dollars while Aziz has 5x dollars. The x is some positive real number.

We're then told that Hakim saved another $82, which means it goes from 3x to 3x+82

At the same time, Aziz spent $110 which means the 5x decreases to 5x-110

At this point, the two people have the same amount of money. Set the expressions we found equal to one another and solve for x.

3x+82 = 5x-110

3x-5x = -110-82

-2x = -192

x = -192/(-2)

x = 96

Then use this x value to compute each expression like so

Both have $370 after Hakim saved that additional $82 and after Aziz spent that $110.

------------------

Extra info:

If we rewind things a bit, Hakim would have 3*x = 3*96 = 288 dollars while Aziz would have 5x = 5*96 = 480 dollars. This is before any additional saving or spending.

Then note how the ratio 288:480 fully reduces to 3:5 after dividing both parts by the GCF 96.
