PLEASE PLEASE HELP WILL MARK BRAINLIEST

Rama09 [41]

Answer:

The answer is

$\huge y = 3x + 21$

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

where

m is the slope

( x1 , y1) is the point

From the question the point is (−5, 6) and slope = 3

The equation of the line is

$y - 6 = 3(x + 5) \\ y - 6 = 3x + 15 \\ y = 3x + 15 + 6$

We have the final answer as

$y = 3x + 21$

Hope this helps you

A model rocket is projected straight upward from the ground level according to the height equation h = -16t2 + 144t, t > 0, w

VashaNatasha [74]

This is a quadratic equation whose graph is a parabola that opens down.

When does the rocket reach its highest point? Note that at that point it will stop ascending, momentarily stop, and then begin descending. Note also that that point is the vertex of the parabola.

The easiest way to find that time value is to use the formula t = -b/(2a).

Here, t at max height is t = -(144) / (2*[-16]) = 4.5 sec (answer.

What's the rocket's height there? To answer this, sub 4.5 sec for t in the given equation, <span>h(t) = -16t^2 + 144t.

Note: Please use " ^ " to indicate exponentiation:

</span> -16t^2 + 144t (not -16t2 + 144t)

Graph the linear equation. 4x+6y= -12

natka813 [3]

Answer:

The points are $( x_1 , y_1 )$ = ( 0 , - 2 ) and $( x_2 , y_2 )$ = ( - 3 , 0 )

These points is plotted on the x-y graph

Step-by-step explanation:

Given linear equation as :

4 x + 6 y = - 12

now, Let the points for the equation be

$( x_1 , y_1 )$ and $( x_2 , y_2 )$

Now, From equation

For, x = 0

4 × 0 + 6 × y = - 12

Or, 0 + 6 × y = - 12

∴ y = $\frac{-12}{6}$

I.e y = - 2

So, $( x_1 , y_1 )$ = ( 0 , - 2 )

Again

For, y = 0

4 × x + 6 × 0 = - 12

Or, 4 × x + 0 = - 12

∴ x = $\frac{-12}{4}$

I.e x = - 3

So, $( x_2 , y_2 )$ = ( - 3 , 0 )

So, The points are $( x_1 , y_1 )$ = ( 0 , - 2 ) and $( x_2 , y_2 )$ = ( - 3 , 0 )

Now, These points is plotted on the x-y graph Answer
