Answer:

-16/3 =x

Step-by-step explanation:

3(x-2)+4x=10(x+1)​

Distribute

3x -6  +4x = 10x +10

Combine like terms

7x -6 = 10x+10

Subtract 7x from each side

7x-6-7x = 10x-7x +10

-6 = 3x+10

Subtract 10 from each side

-6-10 = 3x+10-10

-16 = 3x

Divide by 3

-16/3 = 3x/3

-16/3 =x

Answer:

A

Step-by-step explanation:

Remember that parallel lines have the same slope.

The y-intercept does not matter.

We have the two equations:

[tex]y=x+4[/tex]

And:

[tex]y=x-2[/tex]

The slope is the coefficient in front of the x.

In the first equation, we can rewrite it as:

[tex]y=(1)x+4[/tex]

Therefore, the slope of the first equation is 1.

Similarly, for the second equation, we can rewrite it as:

[tex]y=(1)x-2[/tex]

The slope of the second equation is also 1.

Therefore, since their slopes are equivalent, they are parallel.

Thus, our correct answer is A.

Answer:

There is exactly one more real solution or there is exactly one more complex solution

Step-by-step explanation:

A quadratic equation is a polynomial of degree two

What this means is that a polynomial has two answers.

Now, from the question, we have an answer already which is a real root

Then the other answer which we do not have can take the form of two answers

It can either be a complex root or other wise be a real root

So the answer to this question is that ;

There is exactly one more real solution or there is exactly one more complex solution

Answer:

-8.72811548...   i think

Step-by-step explanation:

a² + b² = c²

8.3² + 2.7² = c²

68.89 + 7.29 = c²

76.18 = c²

√76.18, -√76.18 = c

c = 8.72811548…, −8.72811548…

I think because it's depression, it's -8.72811548...

Answer:

slope is 1/4

Step-by-step explanation:

Use rise over run

The slope of the line will be equal to 1/4.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope of the line is the ratio of the rise to the run of the line.

The formula to calculate the slope of the line is given as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the line is passing through points ( 0,6) and (8,8). The slope of the line is calculated below,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = (8 - 6 ) / ( 8 - 0)

Slope = 2 / 8

Slope = 1 / 4

Therefore, the slope of the line will be equal to 1/4.

Answer:

Step-by-step  think she needs 2.73861528462

The amount of money invested in an account with simple interest at an annual rate of 2.6% would be $22,727.27.

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time peroid.

Simple Interest = (Principal × Rate × Time) / 100

Given that June has a savings account with an annual simple interest rate of 2.6%. She hopes to gain $6,500 in interest over a period of eleven years.

Rate = 2.6 %

Therefore, Simple Interest = (Principal × Rate × Time) / 100

Simple Interest = P× 2.6% × 3

6,500  = P× 2.6/100 × 3

P = 22,727.27

Hence, the amount of money invested in an account with simple interest at an annual rate of 2.6% would be $22,727.27.

Answer:

Step-by-step explanation:

y is proportional to x when it satisfies the equation ...

  y = kx

where k is the constant of proportionality. The equation can be solved for k by dividing by x:

  k = y/x

The value of k for the given relation is ...

  k = (320 mL)/(20 s)

  k = 16 mL/s . . . the constant of proportionality

Then the equation is ...

  y = 16x

Answer: -18

Step-by-step explanation:

Answer:

I think it would be 1 and 3

Step-by-step explanation:

The correct answer is the first, second, and third.

1st Option-

This is pretty simple if you understand how a number line works. All the numbers on the right side are greater no matter what.

2nd Option -

All numbers on all sides could be rational, as we don't know what kind of number line this is.

3rd Option-

This is also correct because like the previous statement, the number line is unknown. We could have repeating numbers as long as the ones on the left side are less than the ones on the right.

4th Option -

This is incorrect because no matter what number line you have, the numbers on the left side are ALWAYS less than the ones on the right.

Answer:

what are the given of that hakdog

Answer:

C or D, they look the same

Step-by-step explanation:

1. The graph passes through (2, -4) and (6, 0). You can use the rise over run formula to find the slope, so if you were to use the line to draw a triangle it would go to the right 2 spaces and up 1. Therefore the slope is 1/2.

2. Then you just need to see where the line crosses the y-axis (the vertical line). You can see here that it crosses at (0, -3).

3. Writing it in slope-intercept form is y = mx + (or -) b. Soooooo it would be y = 1/2x -3.

Answer:

x = -2 1/4

Step-by-step explanation:

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

-2x - 1/2 + 1 = 5

-2x + 1/2 = 5

-2x = 5 - 1/2

-2x = 4 1/2

-x = 2 1/4

x = -2 1/4

Answer:

33.6+(-5.5)=28.1

Step-by-step explanation:

Since positive times negative is equal to negative, we can multiply -5.5 by an addition symbol, making it an addition problem, and making it the same expression.

To evaluate the expression, we can do 33.6-5.5.

When adding or subtraction decimals, write it stacked like a normal problem, and line up the decimal places, like so.

33.6-

 5.5

Then you can subtract normally, getting 28.1

Answer:

2. Answer is 4 and for 3. P= 1/4s

Step-by-step explanation:

Simply divide the values of one another.

This results you with:

8/2 = 4

12/3 = 4

10/5 = 2 -> I think there was an error or typo here

40/10 = 4

The constant proportion would be 4 because it is constant in every situation for S and P.

The equation would be p= 1/4s because 1 value of p would equal 4 s.
