ASAP!! Find the length of side x in simplest form with a rational denominator
lidiya [134]

Answer:

x=\sqrt{14}

Step-by-step explanation:

This triangle is a 45-45-90 triangle.

By using the image I posted, we can find x easily.

So, we have \sqrt{7} as one of the sides.

They hypotenuse, which is x is just \sqrt{7} \sqrt{2}

Simplify and we get x = \sqrt{14}

What is the equation of a line that passes through (-6,2) and has a slope of ‘-(1)/(2)’?
alexandr1967 [171]

Answer:

y=-\frac{1}{2}x -1

Step-by-step explanation:

y=mx+c

y=-\frac{1}{2}x +c

substitute (-6;2)

2=-\frac{1}{2}(-6)+c

2=3+c

2-3=c

c=-1

If a cyclist increases his speed by 3 miles per hour, he can reduce the time required for a 6 mile trip by 10 minutes. What is t
raketka [301]

Answer:

Slower speed = 9 mph

Step-by-step explanation:

Let the initial speed (slower speed) = s mph

Speed 's' = \frac{\text{Distance}}{\text{Time}}

            s = \frac{6}{t} -------(1)

If the cyclist increases the speed by 3 mph then the final speed = (s + 3) mph

He can reduce the time 't' by 10 minutes (\frac{1}{6} hours)

Now, (s + 3) = \frac{6}{t-\frac{1}{6}}

s + 3 = \frac{36}{6t-1} --------(2)

Substitute the value of 's' from equation (1) to the equation (2).

\frac{6}{t}+3=\frac{36}{6t-1}

\frac{2}{t}+1=\frac{12}{6t-1}

\frac{2}{t}-\frac{12}{6t-1}=-1

\frac{2(6t-1)-12t}{t(6t-1)}=-1

\frac{12t-2-12t}{t(6t-1)}=-1

-\frac{2}{t(6t-1)}=-1

6t² - t = 2

6t² - t - 2 = 0

6t² - 4t + 3t - 2 = 0

2t(3t - 2) + 1(3t - 2) = 0

(2t + 1)(3t - 2) = 0

t = -\frac{1}{2},\frac{2}{3} hours

But the time can't be negative.

Therefore, t = \frac{2}{3} hours is the answer.

From equation (1),

s = \frac{6}{\frac{2}{3}}

s = 9 miles per hour.

Slower speed = 9 mph is the answer.

2/3-1/4 I want the answer please
klemol [59]
You want to make the fractions have the same denominator.
2/3 = 8/12
1/4 = 3/12
now subtract the numerator and keep the denominator the same...
8/12 - 3/12 = 5/12
5 1/2 is the answer
