What is the answer i need help

What is the equivalent sum to 2556 over 5000 ???? Idk if u get it

scoray [572]

If over you mean division then it would be 2556 divided by 5000 and that would equal 0.5112 and if you meant it to be addition because sum means the answer of an addition problem then it would be 7556 because of 2556 plus 5000, but i dont know if that is what you meant by your question. if you explain the lesson to me that you are learning, then i might be of more help to you in solving your problem.

Answer:

y = x + 3

Step-by-step explanation:

To know which of the equations represent the relationship between x and y, you need to substitute the x and y values into the equation. If when the equation is solved, the left-hand and right-hand side of the equation equal each other and hence the equation is true, then the equation must be correct in expressing the relationship between the x and y values. If not, then it is not correct.

As this question is only dealing with linear equations, we know that the gradient of the line is constant and hence the rate of change in x and y values is constant. Therefore, we can choose to substitute any of the given combinations of x and y values into the equation to obtain the correct equation. As it is easier to use smaller numbers for smaller calculations, we'll use the first combination of x = 1 and y = 4 .

Equation No. 1 : y = 3x + 1 where x = 1 , y = 4 and x = 2 , y = 5

( 4 ) = 3 ( 1 ) + 1

4 = 4

However, as this equation has a constant not equal to 1 in front of the x variable and hence a different gradient to the other equations, we will substitute the second combination of x and y values.

( 5 ) = 3 ( 2 ) + 1

5 = 6

Therefore, equation is false / incorrect.

Equation No. 2 : y = x + 1 where x = 1 , y = 4

( 4 ) = ( 1 ) + 1

4 = 2

Therefore, equation is false / incorrect.

Equation No. 3 : y = x + 3 where x = 1 , y = 4

( 4 ) = ( 1 ) + 3

4 = 4

Therefore, equation is true / correct.

Equation No. 4 : y = x - 3 where x = 1 , y = 4

( 4 ) = ( 1 ) - 3

4 = - 2

Therefore, equation is false / incorrect.

I NEED HELP PLEASE! :)

Answer:

Perpendicular

Step-by-step explanation:

To tell if the lines are perpendicular/parallel, you must look at the slope, but in this case, you must first get y by itself, like so:

3x + 7y = 15

-3x - 3x

___________

7y = -3x + 15

Divide both sides by 7:

y = $\frac{-3}{7}x + \frac{15}{7}$

Now the other equation:

7x - 3y = 6

-7x -7x

_________

-3y = -7x + 6

Divide both sides by -3:

y = $\frac{7}{3} x - 2$

You can see that the lines are perpendicular because the slopes ( $\frac{-3}{7} x$ and $\frac{7}{3}$ ) are opposite reciprocals.

Answer choices are a. 90 b. 40 c. 10 d. 50 please help

Andrei [34K]

Answer: d. 50

Steps:

1. Find value of x.

5x + 4x = 90

9x = 90

x = 10

2. Use x value to find ∠EDH.

∠EDH = 5x

∠EDH = 5(10)

∠EDH = 50°
