Answer:

y = x - 7

Step-by-step explanation:

x - y - 1 = 0

y = x - 1 .... y = mx + b

m = 1 parallel line has same slope

for (2, -5) m = 1 b = y - mx = -5 - 1x2 = - 7

equation: y = x - 7

Which expression is equivalent to 5^-2 x 5^-1

Mrac [35]

When you multiply powers with the same base, you sum the exponents:

$a^b\times a^c=a^{b+c}$

So, in this case, you have

$5^{-2}\times 5^{-1}=5^{-2-1}=5^{-3}$

A friend of yours claims to be able to ride a bicycle 20 feet per second, is this a reasonable

sp2606 [1]

Answer:

No and yes

Step-by-step explanation:

If the bike is at a sudden hault (A FULL STOP) its physically impossible for the sudden speed of his weight and laws of inertia to pull him forwar that quick.

NOW - if the bike is already in motion and going downhill the gravitational down force will haul his speed at 45MPH and would make him reach the lenght of 66feet per second.

Solve= 10/8 = n/10 <br> Write your answer as an improper fraction in simplest form.

vekshin1

<h2>Answer:</h2>

$n=\frac{25}{2}$ .

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

$\frac{10}{8} =\frac{n}{10}$

<h3>2. Solve the equation for n.</h3>

$\frac{10}{8} =\frac{n}{10}$

$10*(\frac{10}{8}) =(\frac{n}{10})*10$ ----> Multiply both sides by 10.

$10*(\frac{10}{8}) =n$ ----> Simplify.

$\frac{10*10}{8} =n$ ----> Solve the fraction product.

$\frac{100}{8} =n$ ----> Simplify.

$\frac{100/4}{8/4} =n$ ----> Simplify by dividing the numerator and denominator by the same number.

$\frac{25}{2} =n$ ----> Simplify.

$n=\frac{25}{2}$ ----> Reorganize.

<h3>3. Express your result.</h3>

$n=\frac{25}{2}$ .

<em>Note. </em><em>Check the attched image to see the manual solution of the equation. We took the same steps I explained previously in the manual solution.</em>
