Ashley needs to ride her bike to her friends house 96 miles away. She is riding at an average rate of 15 miles per hour. She has 6 hours to get there. Will she make it?

Answers

The relationship between Speed, Distance and Time can be expressed as:

$\rm Distance = Speed * Time$

The total distance to be covered is 96 kilometres. Ashley couldn't cover it with existing speed and in available time.

Given:

$\rm{Average\; speed \;of\; Ashley} =(15\;mile)/(hour)$

$\rm{Time\; available} = 6\;hours$

Now, calculate the maximum distance that is possible to cover.

$\begin{aligned}\rm Distance &= \rm{Speed * Time}\n&=15 * 6\n&=90\end{aligned}$

The total distance to be covered by her is 96 kilometres. Ashley could cover only 90 kilometres.

Average speed of Ashley = 15 miles per hour

Time she has = 6 hours

Distance can be covered = speed × time = 15×6 = 90 miles

But the distance of her friend's house is 96 miles.

So she will not be able to make it.

Factor the expression on the left side of the equation. Then solve the equation.x³ - 2x² - 5x = 0

-5, 0, 3
0, -1 ± √24
0, -1 ± √6
0, 1 ± √6

Answers

x³ - 2x² - 5x = 0

First, take common factor:

x(x^2 - 2x - 5 )= 0

Now use the quadratic formula to find the roots of the trinomial

x = [- b +/- √(b^2 - 4(a)(c)] / 2a

$x = (2 +/- √(4 -4(1)(-5)) )/(2)$

x = [2 +/-2√6 ]/2

x = 1 + √6 and x = 1 -√6

Then the solutions are:

x =0; x = 1 + √6; x = 1 - √6

That is the las option shown.

Solve for x: |2x + 12| = 18

Answers

|2x + 12| = 18

First, break down the problem into 2 equations . / 2x + 12 = 18 and -(2x + 12) = 18
Second, solve the first equation. / $2x + 12 = 18$
Subtract 12 from both sides. / $2x = 18 - 12$
Subtract 18 - 16. / $2x = 6$
Divide both sides by 2. / $x = (6)/(2)$
Simplify. / $x = 3$
Third, solve the second equation. / -(2x + 12) = 18
Simplify your brackets. / $-2x - 12 = 18$
Add 12 to both sides. / $-2x = 18 + 12$
Add 18 + 12. / $-2x = 30$
Divide both sides by -2. / $x = (30)/(-2)$
Simplify. / $x = -(30)/(2)$
Simplify. / $x = -15$
Fourth, collect the solutions. / $x = -15,3$

Answer: x = -15, 3

What is the domain of the following parabola? u-shaped graph that opens down with a vertex of 2, 3

x ≥ 2
x ≤ −1
y ≤ 3

Answers

First we have to understand what the domain is. In a nutshell the domain is the set of all x values that are represented in any given graph. In this case we do not have a graph but we have the vertex. The x value is 2, therefore: x ≥ 2.

I hope this helps, Regards.
