Okay First,
Start with the given equation <span>Subtract  from both sides 
Rearrange the equation 
Divide both sides by  
Break up the fraction 
Reduce 
Looking at  we can see that the equation is in slope-intercept form  where the slope is  and the y-intercept is  Since  this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis

-6(x+6)-10=-2(5+4x)
dimaraw [331]
Assuming you need to solve for x:

-6(x + 6) - 10 = -2(5 + 4x)

start by distributing your numbers outside the front of your parentheses:

-6x - 36 - 10 = -10 - 8x

then combine like terms:

-6x - 46 = -10 - 8x  ... add 10 to both sides (which technically could have cancelled out in the step prior, but regardless)
-6x - 36 = -8x  ... add 6x to both sides
-36 = -2x ... divide both sides by -2
x = 18

A rocket is launched from a tower the height of the rocket why in feet is related to the time after launch X in seconds by the g
lesantik [10]

Answer:

<h3>444m</h3>

Step-by-step explanation:

Given the height of the rocket modelled by the equation;

y=-16x^2+152x+83

The rocket reaches its maximum height when the velocity of the rocket is zero.

Since velocity is the change in displacement with respect to time;

velocity v = dy/dx

dy/dx = -32x + 152

at dy/dx = 0

-32x + 152 = 0

-32x = -152

x = -152/-32

x = 4.75s

To get maximum height reached by the ball, we will substitute x = 4.75 into the modeled function as shown;

y(4.75) = -16(4.75)^2+152(4.75)+83

y(4.75) = -361+722+83

y(4.75) = 444m

Hence the maximum height reached by the ball is 444m

Can somebody help me with this I’ll mark you!?
GuDViN [60]

Answer:

Carol makes 6 more points then Abby.

Step-by-step explanation:

Since Abby made 2 three pointers, that means that she made 6 points in total (2x3). And since Carol made 4 three pointers, it means that she made 12 points in total (4x3). To find how many more points Carol made then Abby, you have to subtract the amount of points that Abby made from the amount of points that Carol made. Doing this, you will see that Carol made 6 more points then Abby.
