Answer:

x=1.818minutes

Step-by-step explanation:

3/60 miles per minute for walk

8/60 miles per minute for run

0.05x + 0.1333y=1

x+y=10

x=y-10

0.05(y-10) + 0.133333y = 1

0.05y-0.5+0.133333y=1

0.18333y=1.5

y=8.18minutes

x=10-8.18

x=1.818minutes

The lines given by the equations y=2x and y=4x+1 are
BartSMP [9]

the equations are already in slope-intercept form, therefore


\bf \begin{array}{|c|ll}
\cline{1-1}
slope-intercept~form\\
\cline{1-1}
\\
y=\stackrel{\stackrel{slope}{\downarrow }}{m}x+\stackrel{\stackrel{y-intercept}{\downarrow }}{b}\\\\
y=mx+b
\\\\
\cline{1-1}
\end{array}~\hspace{8em}y=\stackrel{slope}{2}x\qquad y=\stackrel{slope}{4}x+1


so their slopes are 2 and 4.

parallel lines have exactly the same slope, these ones do not, so they're not parallel.

perpendicular lines, have negative reciprocal slopes, in short, their product gives -1, 2*4 ≠ -1, so they're not perpendicular either.

Use FOIL to derive the identify for (a+b)^2.​
Firlakuza [10]

Answer:

a^2+2ab+b^2

Step-by-step explanation:

FOIL method is First variables Outer variables Inner variables Last variables

(a+b)^2 rewritten is (a+b)(a+b)

F - a*a

O - a*b

I - a*b

L - b*b

a*a+a*b+a*b+b*b

simplify

a^2+2ab+b^2

What is 4.62 expressed as the quotient of two integers in simplest form?
erik [133]
Multiply 4.62 by a number that to get an integer.
Such as multiply by 5 is 23.10 so to get rid of 0.1, just multiply by 50 then it becomes 231.

so that means...
4.62 = 231 / 50

or a simple answer would be multiply by 100, then you get 462.

so....
4.62 = 462 / 100
And then simplify, it is divisible by 2 so the answer is 231/50
