Answer:

First, change 2/5 to tenths. That equals 4/10. Now, we subtract. 7/10 - 4/10 is... that's right! 3/10! That's about 1/4. Good luck!

The equation of the line WX is 2X plus Y equals -5 what is the equation of a line perpendicular to line WX in slope intercept fo
tensa zangetsu [6.8K]

Answer:

y = \frac{1}{2}x - \frac{3}{2}

Step-by-step explanation:

The equation of the line WX is, 2x + y = - 5

⇒ y = - 2x - 5 .......... (1)

This equation is in slope-intercept form and the slope is - 2 and the y-intercept is - 5.

Now, if a line perpendicular to equation (1) having slope m then, m × (- 2) = - 1

⇒ m =  \frac{1}{2}

{Since the product of slopes of two mutually perpendicular straight line is - 1}

Therefore, the equation of the perpendicular line is

y = \frac{1}{2}x + c, where c is a constant and we have to find it.

This above line passes through the point (-1,-2) and hence

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

⇒ c = - \frac{3}{2}

Therefore, the equation of the line will be y = \frac{1}{2}x - \frac{3}{2} (Answer)

Mr Smith is on a road trip from Cleveland to Chicago. He is 65% of the way there , and has already driven 455 miles. How many mo
Keith_Richards [23]
Hi i'd be glad to help you with this equation. 

basically all we have to do is find (65%) of 455*. 

65% of 455* = 295.75 

Next. 

455 + 295.75 = 750.75 

So, to check my work I have 750.75 miles in total. 

I have already driven 455 miles of 750.75 miles. 

Using subtraction we subtract our distance from our total. 

750.75 - 455 = 295.75 

So, in total your answer to this problem is (295.75) 

Hope this helps. 
Have a great day!
