I don't know your options, but if one of them is rounding down and not up it'd be incorrect because .86 is above 5 if that makes sense? (:

Suppose you start at the origin, move along the x-axis a distance of 4 units in the positive direction, and then move downward a

Zanzabum

Answer:

(4,0,-5)

Step-by-step explanation:

Since we move 4 points along +ve x-axis so, x coordinate is 4

We did not move any point along y-axis so y coordinate is 0

we moved 5 points along -ve z-axis so z coordinate is -5

so our position is (x,y,z) = (4,0,-5)

Step-by-step explanation:

The steps taken to solve this system of equations would first be:

1. Sub 4x-2 into your first equation, 2x+5(4x-2)= 12 ->

2. Solve/simplify this equation to get x=1

3. Sub x=1 into your second equation and solve for y = 2

4. Get the solution (1,2)

Answer:

x represents +50 for every hour. the inequality is y = 4x + 500 or y = x + 500.

they can ride it for 4 hours

Step-by-step explanation:

y(total cost) = x(50 per hour) + 500(y-intercept)

1) WET SURPRISE A water balloon is launched off of a patio. The path of the water

mart [117]

The function of the water balloon is an illustration of a quadratic function.

The balloon will splat on the ground after 2.5 seconds

The function is given as:

$h(t) = -6t^2 + 13t + 5$

When the balloon splats on the ground, the value of h(t) is 0.

So, we have:

$-6t^2 + 13t + 5 = 0$

Expand the expression

$-6t^2 + 15t- 2t + 5 = 0$

Factorize the above expression

$-3t(2t - 5)- 1(2t - 5 )= 0$

Factor out 2t - 5 in the 2t - 5

$(-3t - 1)(2t - 5 )= 0$

Split the equation into 2

$-3t - 1 = 0\ or\ 2t - 5= 0$

Rewrite as:

$-3t = 1\ or\ 2t = 5$

Solve for t

$t = -\frac 13\ or\ t = \frac 52$

The value of t cannot be less than 0 i.e. negative.

So, we have

$t = \frac 52$

Divide 5 by 2

$t = 2.5$

Hence, the balloon will splat on the ground after 2.5 seconds
