Find the slope of (1,8) and (3,12) ?
Answer:
The slope is 2.
Step-by-step explanation:
Slope formula is rise/run. So in other words, it is y2-y1/x2-x1. In this case it would be 12-8/3-1. That equals 4/2. You need to simplify that by dividing both 4 and 2 by 2. So, that gives you 2/1. Whenever you have a number over 1 that is the same as saying just the numerator. So the slope would be 2.

Enter a graph compound inequality for the numbers described. Use x as the variable.
all real numbers less than or equal to 9 and greater than or equal to 2
The solution of this inequality is?
Answer:
If y> or y>=, (>= means greater than or equal to), then you shade up. If y< or y<=, (<= means less than or equal to), then you shade down. I remember this by up: greater (because when something is bigger, it's higher) and down: less (because if it's smaller, it's lower). I hope that helps.

Answer:
1. The runner travels 8 miles in 2 hours
2. The runner's speed is 4 miles per hour
Step-by-step explanation:

The runner travels 10 miles in 2 hours.
From the graph determine how much distance travel by runner in 2 hours.
The graph is a demonstration of curves which gives the relationship between x and y axis.
Question seems to be incomplete. Here is the assumed data, from graph.
x (time) in hours = 1 2 3 4 5
y (distance) in miles = 5 10 15 20 25
Here, from data runner travels 10 miles in 2 hours.
Thus, the runner travels 10 miles in 2 hours.

The national debt is about $26.7 Trillion as of today. Let's say that it grows in the future at about 7%, as it has from 2010 until today. Projecting forward 10 years, lets say that the population is about 350 million people at that time. In 10 years from now, approximately how much will the average citizen owe the Federal government, just so that the government can pay all its debts?
Answer:
Approximately, each citizen will owe $81,626 just so that the government can pay all its debts in the coming 10 years
Step-by-step explanation:
What we have here is that the debt grows at a rate of 10% per decade
So in the next 10 years, the worth of the debt will be;
26.7 trillion + 7% of 26.7 trillion
= 26.7 trillion + 1.869 trillion
So the total debt will now be;
= 28.569 trillion
So the amount each of the 350 million citizens owe the government will be;
28.569 trillion/ 350 million
= 81,625.71428571429
Approximately each citizen will owe $81,626
On her first day in a hospital, Kiri receives u1 milligrams (mg) of a therapeutic drug. The amount of the drug Kiri receives increases by the same amount, d, each day. On the seventh day, she receives 21 mg of the drug, and on the eleventh day she receives 29 mg.
a. write down an equation, in the terms u1 and d, for the amount of the drug that she receives on the seventh day.
b. write down an equation, in terms of u1 and d, for the drug that she receives on the eleventh day.
c. write down the value of d and the value of u1.
Answer:
a. 21 = u1 + 6·d
b. 29 = u1 + 10·d
c. d = 2, u1 = 9
Step-by-step explanation:
a. The given parameters are;
The amount of therapeutic drug Kiri receives on her first at the hospital = u1 milligrams
The amount of drug increase received by Kiri each day = d
The amount of drug Kiri received on the seventh day = 21 mg
The amount of drug she received on the eleventh day = 29 mg
Therefore, we have an arithmetic progression with the formula for the nth term given as follows;
aₙ = a₁ + (n - 1)·d
Where;
a₁ = u1
n = The number of terms
Therefore, for the 7th day, the amount of drugs she receives, which is 21 milligrams, is given as follows;
a₇ = u1 + (7 - 1)·d = u1 + 6·d = 21
The equation for the amount of drugs she receives in terms of u1 and d on the seventh day is given as follows;
21 = u1 + 6·d
b. For the eleventh day, the amount of drugs she receives, which is 29 milligrams, is given as follows;
a₁₁ = u1 + (11 - 1)·d = u1 + 10·d = 29
Therefore, the equation for the amount of drugs she receives in terms of u1 and d on the eleventh day is given as follows;
29 = u1 + 10·d
c. Therefore, we have two equations which are given as follows;
21 = u1 + 6·d................(1)
29 = u1 + 10·d..............(2)
Subtracting equation (1) from equation (2) gives;
29 - 21 = (u1 + 10·d) - (u1 + 6·d)
8 = 4·d
d = 8/4 = 2
d = 2
From equation (1), we have;
21 = u1 + 6·d = u1 + 6×2 = u1 + 12
21 = u1 + 12
21 - 12 = u1
∴ u1 = 9
d = 2, u1 = 9.

There are 24 calories in a candy bar. How many calories are there in 33 candy bars ?
Answer: 406
Step-by-step explanation:
Answer:
792
Step-by-step explanation:
The answer is 792 because, we know that there is 24 calories in each bar, so, when calculating total amount of, you wan to multiply that amount by however many bars there are. The reason you multiply is because(using this example) when you have a bar with 24 calories and another bar with the same amount, you just add the two calorie amounts together, or 24 + 24. Since you have 33 bars, you would do that 33 times, which is the same as 24 x 33. So if you calculate 24 x 33, you get 792. Another way to solve this is you can use the formula x=cb where x is the total amount of calories, c is the number of calories in one bar, and b is how many bars you have.

Una empresa comercial vende automóviles cuyo precio es de S/. 60 000, con una cuota inicial del 20%, para cancelar el saldo en 30 meses de plazo.calcula la cuota fija mensual que se pagará seda empresa cobra una tasa de interés simple del 12% semestralmente
Responder:
2560
Explicación paso a paso:
Dado lo siguiente:
Precio del automóvil = 60000
Cuota inicial = 20% del precio = (0.2 * 60000 = 12,000
Saldo = (60000 - 12000) = 48000
La empresa cobra un interés simple del 12% cada 6 meses
Periodo de pago = 30 meses / 6 = 5 periodos
Interés simple: p * r * t
= 48000 * 0,12 * 5 = 28800
Por lo tanto, monto total a reembolsar, incluidos los intereses:
Balance + 28800; 48000 + 28800 = 76800
El reembolso mensual es fijo;
Por lo tanto,
76800/30 = 2560

There are 65 people in a restaurant. The restaurant has a maximum capacity of 84 people. Write an inequality that represents the number x of additional people who can enter the restaurant
Answer:
x+65≤84
Step-by-step explanation:
Inequality that represents the number 'x' of additional people who can enter the restaurant is -
x + 65 ≤ 84
What is inequality?
Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.
Given is a restaurant which has 65 people in it. The restaurant has a maximum capacity of 84 people.
Assume that 'x' more people can enter inside the restaurant. Then -
the inequality can be written as follows -
x + 65 ≤ 84
65 people were already inside. 'x' more people can enter it such that the total number of people inside is either less or greater than 84.
Therefore, inequality that represents the number 'x' of additional people who can enter the restaurant is -
x + 65 ≤ 84
