What is the slope of the line with the equation y-3=-1/2(x-2)?
torisob [31]

Answer:  -\frac{1}{2}

Step-by-step explanation:

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

Write as slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

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

     y = -\frac{1}{2}x+4

Therefore, the slope is -\frac{1}{2}.

A triangle has one angel that measures 51 degrees and one angle that measures 39 degrees. what kind of triangle is it?
sp2606 [1]
Those two angles are complementary - which means they both give us 90 degrees. We know that all three angles in any triangle must be exactly 180 degrees, so the third angle will be 180 - 90 = 90 degrees. It means that our triangle is a <u>straight triangle</u>. The figure will look more less like in the attachment.

You need to strengthen a 19% alcohol solution with pure alcohol solution to obtain 40% solution. How much pure alcohol should yo
Alex73 [517]
Let x be the number of mm of pure alcohol to be added:

I will add the mm to express the volume in mm
100mm.(19%) + (100%).x mL = (100 mL+x mL).(40%).
Now right again without the %
100.(0.19) + x.(1) = (100+x).(0.4)

19 + x = = 40 + 04x
x - 0.4x = 40 - 19
0.6 x = 21
x = 21/0.6  and x = 35 mL. This te quantity of pure alcohol should to be added to get a solution at 40%.
