Answer:

y=50x+0

Step-by-step explanation:

y=mx+b is y-intercept form

I will make x= hours and y= distance (miles)

every 1 you add to x has to represent 50 miles

for the y intercept, it was unspecified so I assumed 0

Hope this helps :)

4/10x - 2x + 8/5 = 4/5

mamaluj [8]

$\large\displaystyle\text{$\begin{gathered}\sf \left(\frac{4}{10}\times x\right)-(2 \times x)+\frac{8}{5}=\frac{4}{5} \end{gathered}$}$

Reduce the fraction 4/10, to its minimum expression, extracting and canceling 2.

$\large\displaystyle\text{$\begin{gathered}\sf \frac{2}{5}x-2x+\frac{8}{5}=\frac{4}{5} \end{gathered}$}$

Combine $\bf{\frac{2}{5}x }$ and -2x to get $\bf{-\frac{8}{5}x}$ .

$\large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x+\frac{8}{5}=\frac{4}{5} \ \end{gathered}$}$

Subtract 8/5 from both sides.

$\large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=\frac{4}{5}-\frac{8}{5} \ \ \end{gathered}$}$

Since 4/5 and 5/8 have the same denominator, join their numerators to subtract them.

$\large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=\frac{4-8}{5} \end{gathered}$}$

Subtract 8 from 4 to get -4.

$\large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=-\frac{4}{5} \end{gathered}$}$

Multiply both sides by $\bf{-\frac{5}{8}}$ , the reciprocal of $\bf{-\frac{5}{8}}$ .

$\large\displaystyle\text{$\begin{gathered}\sf x=-\frac{4}{5}\left(-\frac{5}{8}\right) \end{gathered}$}$

Multiply -4/5 by -5/8 (to do this, multiply the numerator by the numerator and the denominator by the denominator).

$\large\displaystyle\text{$\begin{gathered}\sf x=\frac{-4(-5)}{5\times8} \ \to \ \ Multiply \end{gathered}$}$
$\large\displaystyle\text{$\begin{gathered}\sf x=\frac{20}{40} \end{gathered}$}$

Reduce the fraction 20/40 to its lowest expression by extracting and canceling 20.

$\boxed{\large\displaystyle\text{$\begin{gathered}\sf x=\frac{1}{2} \end{gathered}$}}$

For her tutoring services, Thuy charged Demi $10 per hour and $8 for books and supplies. Demi paid a total of $48.00. Which equa

Fudgin [204]

To find the final amount, you would have to multiply her rate per hour (10) by how many hours she tutored (h). Then, you need to add her flat rate of 8.

10h + 8 = 48, where h is how many hours she tutored.

Find the value of 2 over 3 divided by 6

iragen [17]

Answer:

$\frac{1}{9}$

Step-by-step explanation:

$\frac{2}{3}$ ÷ 6

leave the fraction, change division to multiply, turn 6 upside down

= $\frac{2}{3}$ × $\frac{1}{6}$ ( cancel 2 and 6 by 2 )

= $\frac{1}{3}$ × $\frac{1}{3}$

= $\frac{1(1)}{3(3)}$

= $\frac{1}{9}$

Without the wind, a plane would fly due east at a rate of 150 mph. The wind is blowing southeast at a rate of 50 mph. The wind i

ch4aika [34]

The actual speed of the plane with the wind:
v² = ( 150 + 50 · cos 45°)² + ( 50 · sin 45°)²
v² = ( 150 + 35.355 )² + 35.355²
v² = 34,356.467 + 1,249.976
v = √35,606.452
v = 188.7 mph

(x+6) is a factor of f(x). Solve f(x)=0.<br>x3 - 52x – 96

Mars2501 [29]

<h3>I'll teach you how to solve f(x)=0x63 - 52x – 96</h3>

----------------------------------------------------------

f(x)=0x^3 - 52x – 96

Apply rule:

0 * a= 0

0-52x-96

Group like terms:

-52x+0-96

Add/subtract the numbers:

0-96= -96

-52x-96

Your Answer Is -52x-96
