I really need help. I need to get this done by the end of this week otherwise i will fail the class. PLEASE HELP ME

1.  Subtraction property of equality; multiplication property of equality; division property of equality

For this question, you simply have to state the operation that is occurring.

2.  To solve this, simplify the equation so that it is in y=mx+b form.  From the equation, find two points so that you can plot a line.

4x + y = 6x - 1

y = 2x - 1

-1 is the y-intercept.  This means that you can place a point at (0,-1) which is the -1 on the y (vertical) axis.

For the second point, you can plug any number for the x-value that will stay within the given graph.  I am going to use 2.  

y = 2(2) - 1

y = 4 - 1

y = 3

This gives you the point (2, 3).  Plot the points (0, -1) and (2, 3).  You will be able to draw a line from that.

3.(a)  1200 represents the population of bacteria at the beginning, or when t is equal to 0.

(b)  1.8 represents the factor by which the bacteria increases each hour.  

(c)  1000 represents the beginning population.  The difference means that the total amount of bacteria will increase more slowly than the population that began with 1200.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
