Mathematics

So your equation is 2x^{2} +7x = 4. You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now 4x + 7x = 4.
You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's 11x = 4 right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be

0.36.

6/8=y/16 how do you find the proportion of value y
Katarina [22]
You can set both fractions to have the same denominator by multiplying 6/8 (both the 6 and 8) by 2 to keep the value of the fraction, while turning the denominator to 16. So you get 12/16=y/16.
That means for the equation to be true y has to be 12.

Hope this helps!

Determine the value of K that would make this expression a perfect square
Mumz [18]

Answer: k=9/4

Step-by-step explanation: We can do this by finding a number that adds up to 3 when multiplied by 2. The best way to do this is to use ((b^2)/4) which can usually find you the number for a perfect square based on b, which we have. So, 3^2 / 4 =9/4, meaning k=9/4. We can check:

>x^2 +3x +9/4

> (x+3/2)(x+3/2)

Perfect square.

Which equation is represented by the table?
kozerog [31]
(0,-1)(1,4)
slope = (4 - (-1) / (1 - 0) = (4 + 1)/1 = 5

y = mx + b
slope(m) = 5
(1,4)...x = 1 and y = 4
now we sub
4 = 5(1) + b
4 = 5 + b
4 - 5 = b
-1 = b

equation is : y = 5x - 1...answer C

Calculate the equation of the line if two points are (1,6) and (5,0).<br><br> Explain
topjm [15]

Answer:

y = -3/2x+15/2

Step-by-step explanation:

First calculate the slope

m = (y2-y1)/(x2-x1)

   = (0-6)/(5-1)

   = -6/4

  = -3/2

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

y = -3/2 x+b

Substitute a point into the equation

0 = -3/2(5)+b

0 = -15/2+b

15/2 = b

The equation is

y = -3/2x+15/2
