Answer 1

Answer: x = 3

Step-by-step explanation: First subtract 2x from both sides to get:

3x + 6 = 15

Then subtract 6 on both sides

3x = 9

Now divide by 3 to isolate x to get...

x = 3

Answer 2
5x + 6 = 2x + 15
5x + 2x = 6 + 15
7x = 21 (then you divide 21 by 7)
x= 3
That’s how I do it

how many solutions does 6x−y=−1 6x+y=−1 ​

Answers

Answer:

x=−1/6 and y=0

Step-by-step explanation:

Answer:

There is one solution.

Step-by-step explanation:

x = - 1/6

y = 0

It can be solved simultaneously

6x - y = -1

6x + y = -1

Subtract equation two from equation one

-2y = 0

Divide both sides by-2

y = 0/-2

y = 0

Substitute 0 for y in either of the equations to get x

 

6x - 0 = -1

6x = -1

Divide both sides by 6

x = -1/6

In a survey of 3,200 people who owned a certain type of​ car, 960 said they would buy that type of car again. What percent of the people surveyed were satisfied with the​ car?

HELP NOW!!

Answers

Answer: let

Total number of those who took part in the survey (T)=3200

Those who were satisfied (t)=960

Percentage of those who were satisfied (S)=(t/T)*100

S=(960/3200)*100

S=30%

Therefore only 30% were satisfied

Step-by-step explanation:

Thirty percent of the people surveyed were satisfied with the car.

What is the formula used to find the percentage?

The formula used to calculate percentages is the ratio of value to total value multiplied by 100.

Let's denote  T as the  total number of people who owned a certain type of car and t as the number of people who were satisfied with the car.

Given that,

T =3200

t= 960

The percent of people satisfied with the car is obtained by using the below equation.

[tex](\frac{t}{T} ) * 100[/tex]

(960/3200)*100 = 30%

As a result, the percentage of people who are satisfied with the car is 30%.

Answer:

X = 36/17

y = -8/17

Step-by-step explanation:

Since they both equal y, you could use them equal to each other.

(5/2)x-4=(-1/3)x+2

Then solve for x by combining like terms. X should be 36/17. Plug in x to find y in one of the equations. I will use the top one. (5/3)(36/17)-4=y. That should simplify down to (60/17)-4=y. Y would finally equal -(8/17).

What the other guy said. I think he is correct.

Step-by-step explanation:

Does anyone know how to do this?? Help please!!!!

Answers

Answer:

When we have a rational function like:

[tex]r(x) = \frac{x + 1}{x^2 + 3}[/tex]

The domain will be the set of all real numbers, such that the denominator is different than zero.

So the first step is to find the values of x such that the denominator (x^2 + 3) is equal to zero.

Then we need to solve:

x^2 + 3 = 0

x^2 = -3

x = √(-3)

This is the square root of a negative number, then this is a complex number.

This means that there is no real number such that x^2 + 3 is equal to zero, then if x can only be a real number, we will never have the denominator equal to zero, so the domain will be the set of all real numbers.

D: x ∈ R.

b) we want to find two different numbers x such that:

r(x) = 1/4

Then we need to solve:

[tex]\frac{1}{4} = \frac{x + 1}{x^2 + 3}[/tex]

We can multiply both sides by (x^2 + 3)

[tex]\frac{1}{4}*(x^2 + 3) = \frac{x + 1}{x^2 + 3}*(x^2 + 3)[/tex]

[tex]\frac{x^2 + 3}{4} = x + 1[/tex]

Now we can multiply both sides by 4:

[tex]\frac{x^2 + 3}{4}*4 = (x + 1)*4[/tex]

[tex]x^2 + 3 = 4*x + 4[/tex]

Now we only need to solve the quadratic equation:

x^2 + 3 - 4*x - 4 = 0

x^2 - 4*x - 1 = 0

We can use the Bhaskara's formula to solve this, remember that for an equation like:

a*x^2 + b*x + c = 0

the solutions are:

[tex]x = \frac{-b +- \sqrt{b^2 - 4*a*c} }{2*a}[/tex]

here we have:

a = 1

b = -4

c = -1

Then in this case the solutions are:

[tex]x = \frac{-(-4) +- \sqrt{(-4)^2 - 4*1*(-1)} }{2*(1)} = \frac{4 +- 4.47}{2}[/tex]

x = (4 + 4.47)/2 = 4.235

x = (4 - 4.47)/2 = -0.235

One cell phone company charges a $76 sign-up fee and $40 per month. Another cell phone company charges $136 sign-up fee and $20 per month. Write and solve an equation to determine after how many months the cost is the same

Answers

Answer:

The cost would be same after 3 months.

Step-by-step explanation:

Given that:

Charges of first company;

Sign up fee = $76

Per month charges = $40

Let,

x be the number of months

y be the total cost.

y = 40x + 76      Eqn 1

Charges of second company;

Sign up fee = $136

Per month charges = $20

y = 20x + 136     Eqn 2

For same cost,

Eqn 1 = Eqn 2

40x + 76 = 20x + 136

40x-20x = 136 - 76

20x = 60

Dividing both sides by 20

[tex]\frac{20x}{20}=\frac{60}{20}\\x=3[/tex]

Hence,

The cost would be same after 3 months.

Hey there!

I don't know if it's too late, but oh well: The answer is 108°

Knowing that supplementary angles add up to 180°, and we also know that we have 2 out of 3 of the angle measures, so we can subtract that from 180:

180 - 72 =108°

Answer:

∡APC = 108°

Step-by-step explanation:

∡ APB = 180°

∡ DPB + ∡ CPB + ∡APC = 180°

∡ BPD and ∡DPC have a sum of 72°

then:

72° + ∡APC = 180°

∡APC = 180° - 72°

∡APC = 108°

Find the midpoint of the line segment whose endpoints are (-2, 5) and (6, -9).

(2, -2)
(1, -4)
(4, -4)

Answers

Answer:

The midpoint of the line segment whose endpoints are (-2, 5) and (6, -9) is: (2,-2)

Step-by-step explanation:

Given two points are:

(-2, 5) and (6, -9)

The mid-point is the point that divides a line segment in two equal parts.

Let M be the mid-point then

[tex]M(x,y) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]

Let

(x1,y1) = (-2, 5)

(x2,y2) = (6, -9)

Putting the values in the formula, we get

[tex]M(x,y) = (\frac{-2+6}{2}, \frac{5-9}{2})\\M(x,y) = (\frac{4}{2}, \frac{-4}{2})\\= (2,-2)[/tex]

Hence,

The midpoint of the line segment whose endpoints are (-2, 5) and (6, -9) is: (2,-2)
