Use the distance formula from today’s lesson to find the distance between the point P(−2, 1) and the line y = 2x.
Serga [27]

Answer:

Distance from the point to the line will be \sqrt{5}m

Step-by-step explanation:

We have given the equation of the line is y = 2x\

So the equation of line will be y-2x = 0

Point from which we have to find the distance is (-2,1)

Distance from a point to line is given by d=\frac{Ax+By+C}{\sqrt{A^2+B^2}} , here A = -2 , B = 1 and C = 0

And point x = -2 and y = 1

So d=\frac{-2\times -2+1\times 1+0}{\sqrt{(-2)^2+1^2}}=\sqrt{5}m

So distance from the point to the line will be \sqrt{5}m

Solve for x.<br> I need this ASAP so please help me! <br><br> -x+7= x-5
sattari [20]
-x + 7 = x - 5
add x to both sides of the equation
7 = 2x - 5
add 5 to both sides of the equation
12 = 2x
divide 2 from both sides of the equation
6 = x

What’s the answer for -3(r-4)_&gt;0
Zigmanuir [339]

Answer:

r<4

Step-by-step explanation:

-3(r-4)>0 step 1: distribute the -3

-3r+12>0  explain: -3 times r =-3r, -3 times -4 = 12

next, isolate the -3r by putting 12 on the other side

-3r+12>0    subtract 12 from both sides

-3r>-12    now, divide both sides by -3    (you have to flip the > because you are dividing by a negative) -12 divided by -3 is 4

so you should end up with r<4
