The expression for the account is
a) 3600 -400M where m is the number of months
b) We want the expression to equal 2000
3600 -400M = 2000
c) 3600 is the initial amount in the account
400 is the amount that the account goes down each month
M is the number of months
2000 is the amount left in the account

Find the x and y intercepts and slope of the graph of each equation 2x+3y=-6
Answer:
y-int = 2
x-int = 3
Step-by-step explanation:
2x + 3y = -6
3y = -2x -6
y = -2/3x -2
0 = -2/3x -2
2 = -2/3 x
(-3/2)2 = -2/3x (-3/2)
-6/2 = x
-3 =x

Explain how to plot the point (3, –7) on the coordinate plane.
Answer:
start at the origin, the x-coordinate, 3, means you need to go 3 units to the right. the y-coordinate, -7, mean that you need to go 7 units down
Step-by-step explanation:
Answer:
Coordinates are written in the form (x,y), x being a certain length along the horizontal x axis and y being a certain height along the vertical y axis. Positive y numbers are in the top half of the plane and negative y numbers are on the bottom. Positive x numbers are on the right side of the plane and negative x numbers are on the left. Therefore, (3,-7) would be 3 across to the right from the origin (where the x and y axes intersect) at (3,0) and 7 downwards from that point to (3,-7).

Hw to Convert 4500 ft/h = ft/s
Answer:
1.25 ft/s
Step-by-step explanation:

Explain why it is not reasonable to say that 4.23 is less than 4.135 because 4.23 has fewer digits after the decimal point than 4.135?
Answer:
Because 4.23 has 2 straight after the decimal point which is greater than 1 in 4.135, therefore number of digits doesn't matter.
The number of digits doesn't matter because the value 4.23 has 2 immediately after the decimal point, which is greater than 1 in 4.135.
What are decimal numbers?The accepted method for representing both integer and non-integer numbers is the decimal numeral system. It is the expansion of the Hindu-Arabic numeral system to non-integer values. Decimal notation is the term used to describe the method of representing numbers in the decimal system.
Given that it is not reasonable to say that 4.23 is less than 4.135 because 4.23 has fewer digits after the decimal point than 4.135.
Here the number 4.23 is having 2 after the decimal and the number 4.135 is having 1 after the decimal the number 2 is greater than 1 so the number 4.23 is greater than the number 4.135.

A scientist studied the migration patterns of two types of whales:
The humpback whale traveled 2,000 miles in 25 days.
The gray whale traveled 2,250 miles in 30 days.
Assuming the humpback whale travels the same distance each day, what is the unit rate for the humpback whale in miles per day?
Answer:
80 miles per day
Step-by-step explanation:
Let the unit rate be x miles per day for humpback whale
It means that in one day humpback whale travels x miles
Given that it traveled for 25 days
in 1 day humpback whale traveled = x miles
in 1*25 days humpback whale traveled = x*25 miles
Thus, in 25 days humpback whale traveled 25x miles
given that humpback whale traveled 2000 mile sin 25 days
thus,
25x = 2000
x = 2000/25 = 80
Thus, unit rate for humpback whale is 80 miles per day

When data consist of rates of change, such as speeds, the harmonic mean is an appropriate measure of central tendency. The harmonic mean for n data values, assuming no data value is 0, is given by the equation below. Suppose you drive 53 miles per hour for 100 miles, then 67 miles per hour for 100 miles. Use the harmonic mean to find your average speed. (Round your answer to two decimal places.)
Answer:
The answer is "64.19".
Step-by-step explanation:
[tex]\text{Average speed = Harmonic mean speed}[/tex]
[tex]= \frac{2}{\frac{1}{60} + \frac{1}{69}}\\\\ = \frac{2}{\frac{69+60}{4,140} }\\\\ = \frac{2}{\frac{129}{4,140} }\\\\= \frac{2}{0.0311594203 }\\\\ = 64.1860465 \\\\ \bold{= 64.19}[/tex]
The final answer is "64.19".

9514 1404 393
Answer:
1. 2.5 N
2. 39 N
Step-by-step explanation:
1. The side ratios are 1.5 : 2 = 3 : 4, so the third side of the triangle will be the one that makes the ratios 3 : 4 : 5 = 1.5 : 2 : 2.5.
T = 2.5 N
__
2. The side ratios are 15 : 36 = 5 : 12, so the third side of the triangle will be the one that makes the ratios 5 : 12 : 13 = 15 : 36 : 39.
T = 39 N
_____
The point of learning about "special triangles" is that you can use the ratios of side lengths to solve other problems quickly and easily. Ratios are equivalent when every member of the ratio is multiplied by the same value.
In problem 1, the (3, 4, 5) triple is multiplied by 0.5.
In problem 2, the (5, 12, 13) triple is multiplied by 3.
