Step-by-step explanation:
xy + 10 = 0. => y = -10/x.
2x + 3y = 7. => 3y = -2x + 7, y = -2/3 x + 7/3.
When -10/x = -2/3 x + 7/3,
-10 = -2/3 x² + 7/3 x, 2/3 x² - 7/3 x - 10 = 0.
=> 2x² - 7x - 30 = 0
=> (2x + 5)(x - 6) = 0
=> x = -2.5 or x = 6.
dy/dx = d/dx [-10/x] = 10/x².
When x = -2.5, dy/dx = 10 / (-2.5)² = 1.6.
When x = 6, dy/dx = 10 / (6)² = 5/18.
Hence the gradients at the points are 1.6 and 5/18.
Distributive property, the parenthesis means you multiply.
P=S1+S2+S3
P=2.3x+14+2x-0.2x+15
P=4.1x+29
The answer is the first one

Answer:7,350 ways
Step-by-step explanation:
Since there is no restriction in the selection , the first thing is to select the 4 men from the 10 male , this can be done in 10 C 4 ways , which
= 210 ways
Also , we will select the 4 women from the 7 females , this can be done in 7 C 4 ways , which = 35
Altogether the team of 8 can be selected in 35 X 210 ways = 7,350 ways
True because the second and eighteenth day are sixteen days apart r 2 weeks 2 days so the 16th day would be monday and the 18th would be wenesday
