Please answer it correctly I need it today please help
alexdok [17]

Answer:

I am about 95% sure that this is what they want. P.s (sorry I cant put the divide symbol)

<u><em>The variable is the number of shirts she bought or x</em></u>

and the equation is <u><em>(375+50) divided by (15+2) = x</em></u>

in the solve spot put

<em><u>(375+50) divided by (15+2)=x</u></em>

<em><u>425 divided by 17=x</u></em>

<em><u>x=25</u></em>

Then your answer would be <u><em>25</em></u>

Step-by-step explanation:

first add 50 to 375 so you get the full price which will give you 425. then to find out how many shirts she bought you must add 2 to 15 to get 17. then divide 425 by 17 which is 25. so she bought <em><u>25 shirts</u></em>.

Which of the following represents the equation of the line passing through (-4,5)
Sergio [31]

Answer:

Answer: y=2x+13.

Step-by-step explanation:

Your input: find the equation of the line perpendicular to the line y=5/2−x/2 passing through the point (−4,5).

The equation of the line in the slope-intercept form is y=5/2−x/2.

The slope of the perpendicular line is negative inverse: m=2.

So, the equation of the perpendicular line is y=2x+a.

To find a, we use the fact that the line should pass through the given point: 5=(2)⋅(−4)+a.

Thus, a=13.

Therefore, the equation of the line is y=2x+13.

Answer: y=2x+13.
