Slope intercept form what is y - 3x = 19

1 answer:

7 0

Slope-intercept form is y= mx+b, so all you have to do is to single out the y.

y= 3x+19 (added 3x to both sides to cancel and single itself from the y)

Answer: The shorter piece of the pipe is 9.25 inches long

Step-by-step explanation: First, we need to make an equation. 50 = 13 + 4x + x. We do subtraction first so it becomes 37 = 4x. Divide both sides by 4 so x = 9.25. The short piece of the pipe is 9.25 inches. Hope this helps!

Answer:

StartFraction 2 plus or minus StartRoot (negative 2) squared minus 4(1)(negative 3) EndRoot Over 2(1) EndFraction

Step-by-step explanation:

General quadratic equation: ax^2 + bx + c

where a is the coefficient of the quadratic term, b is the coefficient of the linear term and c is the independent term. Here the equation is: x^2 – 2x – 3, so a = 1, b = -2 and c = -3

Quadratic formula:

$x = \frac{-b \pm \sqrt{b^2-4(a)(c)}}{2(a)}$

Replacing

$x = \frac{2 \pm \sqrt{(-2)^2-4(1)(-3)}}{2(1)}$

Which set of three sides can be used to make a right triangle. Please show work !

Alexandra [31]

Answer:

D. 39, 80,89

Step-by-step explanation: In order for the side lengths to make a right triangle, they have to satisfy the phythagorean therom $a^{2} + b^{2} = c^{2}$ So $39^{2}$ is 1521 and $80^{2}$ is 6400. 1521+6400= 7921. So thats the $a^{2} + b^{2}$ part and then 7921 has to be equal to $c^{2}$ and $89^{2}$ is 7921. 7921 is equal to 7921 and therefore $a^{2} + b^{2}= c^{2}$ and it forms a right triangle.
