Put 4y= -3x - 8 into slope intercept form.​
zhuklara [117]

Answer:

y = -3/4x -2

Step-by-step explanation:

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

4y = -3x-8

Divide each side by 4

4y/4 = -3x/4 -8/4

y = -3/4x -2

The function h(t) = -16t^2 + 16t represents the height (in feet) of a horse (t) seconds after it jumps during a steeplechase.
Vladimir79 [104]
A.) To find the maximum height, we can take the derivative of h(t). This will give us the rate at which the horse jumps (velocity) at time t.

h'(t) = -32t + 16

When the horse reaches its maximum height, its position on h(t) will be at the top of the parabola. The slope at this point will be zero because the line tangent to the peak of a parabola is a horizontal line. By setting h'(t) equal to 0, we can find the critical numbers which will be the maximum and minimum t values.

-32t + 16 = 0

-32t = -16

t = 0.5 seconds

b.) To find out if the horse can clear a fence that is 3.5 feet tall, we can plug 0.5 in for t in h(t) and solve for the maximum height.

h(0.5) = -16(0.5)^2 + 16(-0.5) = 4 feet

If 4 is the maximum height the horse can jump, then yes, it can clear a 3.5 foot tall fence.

c.) We know that the horse is in the air whenever h(t) is greater than 0. 

-16t^2 + 16t = 0

-16t(t-1)=0

t = 0 and 1

So if the horse is on the ground at t = 0 and t = 1, then we know it was in the air for 1 second.

Find the sum or difference of (2m+7)-(3-4m)
pickupchik [31]
(2m + 7) - (3 - 4m) 

First distribute the (-) in front of the quantity of 3 - 4m. 
Think of it as this: 

-1(3 - 4m) 

You multiply each number inside the parenthesis by -1. 

So: 

3*-1 = -3
-4m * -1 = 4m

Now that you've distributed the negative you can remove the parenthesis. 
Now you'll just set it all up like you would any normal problem. Because -3 is negative you'll make it subtract.... I'll show you what I mean: 

2m + 7 - 3 +  4m 

Combine like terms (Terms which have the same variables... in this case the same number of m's)

Rearranging them can help!

4m + 2m + 7 - 3 

6m + 7 - 3

6m + 4, is our difference!
