What is the distance between the point (-7,3) and (4, -5) on a coordinate plane?
Evgesh-ka [11]
To find this, use the distance formula. D= square root over... (x2-x1)^2+ (y2-y1)^2. Now plug in your coordinates.
D= square root... (4- -7)^2+ (-5-3)^2. Simplify. 4- -7=11 (two neg= positive) -5 -3= -8. So,
D= square root... 11^2+ -8^2. Simplify. 11^2= 121. And -8^2=64. Now just take the square root after adding. 121+64= 185. And the square root of 185 isn’t a whole number, so your final answer is D= (square root over) 185. Hope this helps

4x - 1<br> 2.<br> = x + 7<br> Can someone help please?
tatiyna

Answer:

6\frac{1}{3}

Step-by-step explanation:

4x-12 = x+7

4x-12+12 = x+7+12

4x = x+19

4x-x = x+19-x

3x=19

x = 6\frac{1}{3}

And if we substitute the value of x into the equation 4x-12 = x+7,

we will get 13\frac{1}{3} = 13\frac{1}{3} in the end.

Hope this helps :)
