Answer:

The constant speed with Ed is travelling is 60 mile per hour

Step-by-step explanation:

Given as :

The distance cover to travel from Jefferson to Holden is (D1) 250 miles

The distance cover to travel from Holden to Paxton is (D2) 50 miles

Total time taken to complete entire journey = T = 5 hours

Let The constant speed of Ed = S mph

Time = \frac{Distance}{Speed}

Or, Time = \frac{D1}{S}  + \frac{D2}{S}

Or, 5 hour =  \frac{250}{S}  + \frac{50}{S}

Or, 5 × S = 250 + 50

So,  5 × S = 300

∴           S = \frac{300}{5}

I.e         S = 60 mph

Hence , The constant speed with Ed is travelling is 60 mile per hour Answer

Consider the line 7x+9y=5
alisha [4.7K]

Answer:

The slope of a line parallel to this line will be: -7/9

The slope of the perpendicular line will be:

\frac{-1}{\frac{-7}{9}}=\frac{9}{7}

Step-by-step explanation:

We know the slope-intercept form

y=mx+b

Here,

  • m is the slope
  • b is the y-intercept

Given the equation

7x+9y=5

simplifying to write in the lope-intercept form

y=-\frac{7}{9}x+\frac{5}{9}

Thus, the slope of the line is: -7/9

The slope of a line parallel to the line:

We have already determined that the slope of the line is: -7/9

  • We know that the parallel lines have the same slope.

Thus, the slope of a line parallel to this line will be: -7/9

The slope of a line perpendicular to the line:

We have already determined that the slope of the line is: -7/9

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.

Thus,  the slope of the perpendicular line will be:

\frac{-1}{\frac{-7}{9}}=\frac{9}{7}

PLEASE HELPP I AM FAILING AND I NEED THIS ASAP!!! TYSM
Lana71 [14]

Answer:

See below for answers

Step-by-step explanation:

Do you mean f(x)=2sin(x-1) or f(x)=2sin(x) -1?

Use the formula f(x)=asin(bx+c)+d where |a| is the amplitude, -\frac{c}{b} is the phase shift, d is the vertical shift, and the period is \frac{2\pi}{|b|}.

Assuming your first case is true, the amplitude would be |a|=|2|=2, your period is \frac{2\pi}{|1|}=2\pi, and your midline/vertical shift is d=0.

Assuming your second case is true, everything but the vertical shift stays the same. It would be d=-1 in this case.
