Answer:
(1) m = -5, b= 1
put b=1 (given)
=> y = -x/a + 1
-1/a is representing slope here which is given as -5
-1/a = -5 => a = 1/5
slope intercept form
y = mx +b
y = -5x + 1
standard form
5x +y = 1
(2). (1, -2), (3, 3)
m = 5/2
slope intercept form
y - 3 = 5/2*( x -3)
y = 5x/2 -9/2
standard form
5x -2y = 9
(3). (-2, 0) and (0,5)
m = 5/2
slope intercept form
y - 0 = 5/2 ( x+2)
y = 5x/2 + 5
standard form
5x -2y = -10
(4). a = 2, b = -7
slope intercept form
y = 7x/2 -7
standard form
7x -2y =14
(5). m=2,(3,-1)
slope intercept form
y +1 = 2(x -3)
y = 2x -7
standard form
2x -y = 7
<span>Answer: occurs when the aortic and pulmonary valves backfill with blood</span>
The second heart sound,that is heard in normal hearts, is generated by the closing of the semilunar valves((the aortic valve and pulmonary valve). Before that, the first sound corresponds to the closing of the atrioventricular valves.
Answer: Option A) The seals would decrease in number and the phytoplankton would increase in number
Explanation:
The food web can be illustrated as follows: Seal --> Krill --> Phytoplankton
Where phytoplankton is the producer of food, krill is the primary consumer while seal is the secondary consumer.
So, reducing the krill population would immediately cause food shortage for seals, and lessen consumption of phytoplanktons.
Thus, the seals would decrease in number due to starvation and death, while the phytoplankton would increase in number
