The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Please help me with both questions :(
Answer:
2.) $520
3.) less
Step-by-step explanation:
I'm going to assume that the interst is compoudning and is convertable once a year
The compound interest formula for interest compounding only once a year is as follows
[tex]AV=PV(1+i)^n[/tex]
plug in the numbers and get
[tex]500(1+.04)^{1}=500*1.04=520[/tex]
3.) If the interest rate is lower at the credit union he would obvioulsy be paying less (assuming that this interest rate is convertable annually as well)
A cellphone company charges you $17 a month plus $0.25 for each text message you send. The total bill last month was $45.50. Which of the following equations could you use to figure out how many text messages you sent?
17x - 0.25 = 45.50
17x + 0.25 = 45.50
17 - 0.25x = 45.50
17 + 0.25x = 45.50

ACBStep-by-step explanation:
On a position-time graph, "does not move" means the position is a constant—a horizontal line.
"Positive velocity" means the position is increasing as time increases. The graph goes up to the right. The rate of change (slope) is the velocity.
"Negative velocity" means the position is decreasing as time increases. The graph goes down to the right. Again, the rate of change (slope) is the velocity.
The various sections of the graph are identified in the attachment.

The value of m is 7 in the equation [tex]-5m = -35.[/tex]
The given equation is [tex]-5m = -35[/tex].
In the equation, the variable is m.
To find the value of m, divide both sides by 5:
[tex]-m=-\frac{35}{5}[/tex]
[tex]-m=-7[/tex]
The minus sign on both sides will be cancelled.
[tex]m=7[/tex]
Hence, the value of m is 7 in the equation [tex]-5m = -35.[/tex]

In the figure below, lines L and M are parallel and line AB = line BC = line AC. What is the measure of the exterior angle
at angle C?
*check the picture*
Answer:
120º
Step-by-step explanation:
angles of an equilateral triangle are equal so..
180 ÷ 3 = 60º
to get the exterior m⦣C
180 - interior m⦣C = exterior m⦣C
180º - 60º = 120º

Q6. A colony of ants is beg please help, I don’t know this and I have to hand it in in 20 mins
increases exponentially at a rate of 10% per week. Initially there are 500
ants.
a) Show that the number of ants in the colony forms a geometric progression
b) The number of ants in week 8 is p times greater than in week 6. Find the value of p.
Answer:
a) The number of ants in week three is shown through the following geometric progression: 500*1.1*1.1*1.1
b) 1.21
Step-by-step explanation:
We know that 500 ants are increasing at a rate of 10% every week which means that we can calculate the week one ants like this
500*1.1
Week two
500*1.1*1.1
and so on.
We write the following equation
500(1.1)^n where n is the number of weeks
We plug in 8 and then 6 for n in the equation above and get
500(1.1)^8=1071.79
500(1.1)^6=885.78
Divide and get that p=1.21

-x + 4y = 12
x + y = - 7
Answer:
y = 1, x = - 8
or
(-8, 1)
Step-by-step explanation:
-x + 4y = 12
x + y = -7
add the equations together
0x + 5y = 5
5y = 5
y = 1
substitute y for 1 in one of the original equations to find x
x + y = -7
x + 1 = -7
x + 1 - 1 = - 7 - 1
x = - 7 - 1
x = -8
