Given the standard form of the equation,solve for y, What is y if x=4?

1 answer:

8 0

Well, I'm not sure since you didn't post the equation but, all you have to do is plug in the number 4 where x is. So for example, say the equation given to you was y=6x+5. Just plug in 4 for x and you get y=6(4)+5, which is y=29.

2х + бу = 12<br> slope interception form

olga2289 [7]

Answer:

The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Subtract 2x 2 x from both sides of the equation. Divide each term by −6 - 6 and simplify. Divide each term in −6y=12−2x - 6 y = 12 - 2 x by −6 - 6 .

Step-by-step explanation:

19. For livesh's Model A rocket, he uses the equation h=-490^2+ 1120t. When is the height of the Model A rocket 640 centimeters?

Nadusha1986 [10]

Answer:

t = 1.143 s

Step-by-step explanation:

The equation he uses to model the height of the rocket in cm, as function of time is

h(t) = -490 t^2 + 1120t

We can plot this equation using a graphing tool

Please, see attached picture

The rocket reaches his maximum height (640 cm) at

t = 1.143 s

Decide whether the pair of lines is parallel, perpendicular, or neither.

maw [93]

The lines are: B) Perpendicular

Step-by-step explanation:

we have to convert both lines in slope-intercept form to find slopes

So,

$3x - 6y = -13\\-6y = -3x-13\\\frac{-6y}{-6} = \frac{-3x-13}{-6}\\\frac{-6y}{-6} = \frac{-3x}{-6}+\frac{-13}{-6}\\y = \frac{1}{2} +\frac{13}{6}$

Let m1 be the slope of first line

$m_1 = \frac{1}{2}$

For the second line:

$18x + 9y = 5\\9y = -18x+5\\\frac{9y}{9} = \frac{-18x+5}{9}\\\frac{9y}{9} = \frac{-18}{9}x+\frac{5}{9}\\y = -2x+\frac{5}{9}$

Let m2 be the slope of line 2

So,

If the lines are parallel, their slopes are equal

If the lines are perpendicular, product of their slopes is -1

We can see that

$\frac{1}{2} * -2 = -1$

Hence,

The lines are: B) Perpendicular
