Answer: 
Step-by-step explanation:

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


Therefore, the slope is
.
Answer:
y=4
Step-by-step explanation:
y=-2/3x+4
y=-2/3(0)+4
y=0+4
y=4
The correct answer is: 27 .

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.
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%.
