What is the equation of the line?The standard form of a line equation is ax + by + c = 0. The coefficients are a and b, the variables are x and y, and the constant term is c. It is a one-degree equation with variables x and y. The coordinates of a point on the line defined in the coordinate plane are represented by the values of x and y.For the given question;
The equation of line in the standard form is given as;
Ax + By = C, where C = 24
Part a: Graph 1.
Locate two points lying on the line.
(4, 0) and (0, 3)
Put the value in equation at (x, y) and solve the equation,
Ax + By = C
4A + 0B = 24
A = 24/4
A = 6
And, 0A + 3B = 24
B = 24/3
B = 8
Thus, A and B are 6 and 8 respectively.
Part b: Graph 2.
Locate two points lying on the line.
(3, 0) and (0, 2)
Put the value in equation at (x, y) and solve the equation,
Ax + By = C
3A + 0B = 24
A = 24/3
A = 8
And, 0A + 2B = 24
B = 24/2
B = 12
Thus, A and B are 8 and 12 respectively.

the ages of students at a university are normally distributed with a mean of 23. what percentage of the student body is at most 23 years old?
By the concept of mean ,50% of the student body is at most 23 years old.
What is mean?In mathematics, particularly in statistics, there are various kinds of means. Each mean is used to summarize a certain set of data, frequently to help determine the overall significance of a particular data set. Two easy steps can be used to determine the mean, or average, of a set of data: Add up all of the values to get the sum. Divide the total by the total number of values in the data collection. A data set's mean (average) is determined by summing all of the numbers in the set, then dividing by the total number of values in the set. When a data collection is ranked from least to greatest, the median is the midpoint number. The number that appears most frequently in a set of data is called the mode.

Jon used a gift card to pay for an $17 shirt.The remaining balance on the card is $31.Write and solve an equation that representsthis.
Answer
The initial amount on Jon's giftcard is $48.
Explanation
Let the initial amount on Jon's gift card be x dollars.
Jon pays $17 for a shirt using the gift card and the remaining balance was $31.
That is, the equation representing this is
x - 17 = 31
To solve this, we add 17 to both sides
x - 17 + 17 = 31 + 17
x = 48 dollars
The initial amount on Jon's giftcard is $48.
Hope this Helps!!!
Good evening,
Answer: x-17=31 is the equation you're looking for meanwhile its result is x=48
Explanations: Jon spent $18 after having $31 on the card so they're spending money off the card, therefore the equation you're loooking for is x-17=31. In order to solve it add 17 to the other side of the equation such as:
x-17=31 ; x=31+17 ; x=48

the sum of an integer and five times the next consecutive odd integer is -32. Find the value of the lesser integer
The value of the lesser integer is a = -7
How to find the value of the lesser integer?
Let an integer be = a
Let the next consecutive odd integer (b) = a+2
a + 5( b) = -32
a +5(a+2)= -32
a+ 5a +10 = - 32
6a = -32 -10
6a = -42
a = - 42 /6
a = - 7
The integer a = -7
The next consecutive odd integer (b) = a+2
= -7 + 2
b = -5
So, the value of the lesser integer is a = -7

Jimmy is buying balloons and party hats for his little sister’s birthday party. The party store charges $1.50 for each bag of balloons and $6.00 for each package of hats. Which of the following equations could be used to determine different combinations of b bags of balloons and h packages of party hats that he could buy for a total of $24 A.) b+h=24
B.) (1.50+6.00)(b+h)=24
C.) 1.50b+6.00h=24
D.) 6.00b+1.50h=24
Please provide how you did it so I can understand
Answer:
The answer is C.
Step-by-step explanation:
Since the party store charges $1.50 for each bag of balloons, the total price depends on how many bags of balloons Jimmy purchases. So to represent that amount we use the variable given, b. To represent that we can do 1.50b. If we substitute any positive number for b it could look something like this:
(1.50)(1) or 1.50 × 2.
In addition to this, they also sell packages for $6.00 each. We do the same as with the balloons and use the variable h to represent the number of packages Jimmy buys.
We already know that he spends $24 in total but we do not know how many of each item he bought. So we would represent the unit rate price × the variable (or the unknown number of items) of the balloons + the unit rate price and the unknown number of the party hats.
1.50b + 6.00h = 24.

What is Compound Interest ?
Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit. Reinvesting interest, or adding it to the lent capital rather than paying it out or seeking repayment from the borrower, results in interest being received on the principal amount plus previously collected interest in the next period.
Formula used,
A=P(1+r/n)^nt
A = ending amount
P = principal amount(beginning amount)
n = time period
r = rate of interest
Given,
A = $350000
p = $250000
r = 2.04% or 0.0204
n = 12 months
Now, put these values in given formula
350000 = 250000(1 + 0.0204/12)^12t
= 250000 * 1.0017^12t
350000/250000 = 1.0017^12t
1.4 = 1.0017^12t
Take log on both the sides,
㏑(1.0017^12t) = ㏑(1.4)
12t * ㏑(1.0017) = ㏑(1.4)
12t * 0.0017 = 0.3365
t = 0.3365 / 0.0204
t = 16.5 years
Therefore, Shannon will take time 16.5 years to have $350000

When the plane reaches an altitude of 2,000 ft temperature will be 59.3F
What is altitude?The height of a thing above the surface of a planet or natural satellite, like the sea or land is known as altitude.A distance measurement between a reference datum and a point or object, typically in the vertical or "up" direction, is known as altitude, height, or depth.
Although the term "altitude" is frequently used to refer to a location's height above sea level, the term "elevation" is frequently preferred in the context of geography. The term "depth" often refers to vertical distance measurements taken in the "down" direction.
For every 1000 ft there is a drop of 1.2 Fahrenheit
∴ for 2000ft drop in temperature of 2×1.2=2.4F
Also the temperature on the ground is 61.7F
