Step-by-step explanation:
Has greater balance = Heba
Has more debt = Nour
Read the "note" thing on there it says banks use Negative balances meaning the negative sign ( minus sign) to represent an account with debt which means an account that is owning money e.g -$11, -$15 etc.And they use positive balances meaning the positive sign to represent account that contains valuee.g $2, $7 etc( You might wonder why I didn't put a positive sign on it, the reason is because it's already a positive number so no need to add a positive sign (+) to it) ( BUT they can still add a positive sign to it but it isn't necessary )If you see any number or amount without a negative sign (-) then that number or amount is positive e.g 1, 2,3,4,5,6,11,14,17,20,100,8, $3, $15, $23 and so on..
Hope this helps.Good luck ✅.
Using the number line:
Heba has the greater account balance
Nour has the most debt.
What is a Number Line?A number line shows where a number lies according to the order. Values greater than 0 and are on the right side are greater than values and vice versa.
Given their balances, $29.17 is greater than -$11.99. Therefore, Heba has the greater account balance using the number line.
Since - indicates debt, Nour has the most debt.

Answers
Answer:
x = -9, y = 8
or,
(-9, 8)
Explanation:
Equation 1: 2x + 3y = 6
Equation 2: 4x - y = -44
To solve by substitution, make y subject for equation 2.
4x - y = -44
-y = -44 - 4x
y = 4x + 44
Substitute this y value into equation 1.
2x + 3(4x + 44) = 6
2x + 12x + 132 = 6
14x = 6 - 132
14x = -126
x = -9
Now, find y value:
y = 4x + 44
y = 4(-9) + 44
y = 8
To check for solution, insert x and y value in either equations.
2x + 3y = 6
insert values
2(-9) + 3(8) = 6
6 = 6
Hence, the solution is correct as both sides equal.
Therefore x = -9 and y = 8.
Step-by-step explanation:Substitution method
Equation (1) ——— 2x + 3y = 6
Equation (2) ——— 4x - y = -44
When using substitution method , make x the subject of equation (1).
2x + 3y = 6
2x = 6 - 3y
x = 3 - 3y/2
Substitute the value of x in equation (2) to find y.
4(3 - 3y/2) - y = -44
12 - 6y - y = -44
Subtract 12 from both sides.
12 - 12 - 7y = -44 - 12
-7y = -56
y = 8
Substitute the value of y in equation (1) to find x.
2x + 3y = 6
2x + 3(8) = 6
2x +24 = 6
Subtract 24 from both sides.
2x + 24 - 24= 6 - 24
2x = -18
x = -9
Therefore x = -9 and y = 8.
To check out the solution.
Equation (1) 2x + 3y = 6 , x = -9 , find y.
Substitute the value of x
2(-9) + 3y = 6
-18 + 3y = 6
Add 18 to both sides.
-18 + 18 + 3y = 6 + 18
3y = 24
y = 8
Substitute the value of y in equation (1) .
2x +3(8) = 6
2x + 24 = 6
Subtract 24 from both sides.
2x + 24 - 24 = 6 -24
2x = -18
x = -9
As you can see when you substitute the value of x and y in the equation(1) , you get the same value of x and y ,which is -9 and 8 respectively. So the solution is correct.

The form of the graph is

The graph passes through the points (2, 0) and (6, -2).
So, we have:
[tex]0 = a\sqrt{2 + b[/tex] and [tex]-2 = a\sqrt{6 + b[/tex]
Solve for b in [tex]0 = a\sqrt{2 + b[/tex]
Divide both sides by a

Square both sides
0 = 2 + b
Subtract 2 from both sides
b = -2
Substitute b = -2 in [tex]-2 = a\sqrt{6 + b[/tex]
[tex]-2 = a\sqrt{6 -2[/tex]
[tex]-2 = a\sqrt{4[/tex]
Evaluate the square root
-2 = 2a
Divide by 2
a = -1
Substitute b = -2 and a = -1 in [tex]f(x) = a\sqrt{x + b[/tex]

The range of values of y is -1.6 < y < 7
How to determine the range?The complete question is added as an attachment
From the attached image, we have the following sides
4y + 15 and 5y + 8
Both sides must be greater than 0.
So, we have:
4y + 15 > 0 and 5y + 8 > 0
Rewrite as:
4y > -15 and 5y > - 8
Solve for y
y > -3.75 and y > -1.6
If y is less than -1.6, the side 5y + 8 would be negative.
So, we make use of the inequality y > -1.6 as one of the range
Also, 4y + 15 is greater than 5y + 8.
So, we have:
4y + 15 > 5y + 8
Evaluate the like terms
-y > -7
Divide by -1
y < 7
So, we have:
y > -1.6 and y < 7
Combine both inequalities
-1.6 < y < 7
Hence, the range of values of y is -1.6 < y < 7

3. Jorge earns a 9% commission on all of his sales. He had sales of
$89,400 for the month. Harris works for a different company, and also
sold $89,400 for the month but made $447 more than Jorge. What is
Harris' commission rate?
Answers
The commission rate exists at $8,493 with a rate of 9.5%.
How to estimate the commission rate?
Jorge earns 9% from all his sales, so his commission exists
89400 × 0.09 = $8046
Harris made $447 more than that, so his commission exists
8046 + 447 = $8493
To estimate his commission rate, we can utilize the subsequent equation
89400 × rate percentage = 8493
Rate percentage = 8493 / 89400
Rate percentage = 0.095
Rate percentage = 9.5%
So Harris' commission exists at $8,493 with a rate of 9.5%.
Therefore, the commission rate exists at $8,493 with a rate of 9.5%.

Alice and Bob both go to a party which starts at $5:00$. Each of them arrives at a random time between $5:00$ and $6:00$. What is the probability that the number of minutes Alice is late for the party plus the number of minutes Bob is late for the party is less than $45$
Answers
The probability comes out to be 9/32.
Deducing Arrival Time Possibility
All the possible arrival times by Alice and Bob, in minutes after 5 PM, is constrained by the values of given values of x and y,
x = 0, y = 0, x = 60, y = 60.
Here, let the values of x represent how many minutes after 5 PM Alice arrives at the party.
Let the y values represent the time in minutes that Bob arrives at the party after 5 PM.
Calculating the Required Probability
The times that concern us, however, are obtained by the following probability function,
x + y ≤ 45.
And x = 0, y = 0, and x + y ≤ 45 define the constraints of this probability function. Thus the perimeter of such a graph will be given as,
(45² / 2) = 1012.5 square units
Since the total area of the various arrival times is 60 x 60, or 3600 square units, the probability that Alice and Bob will arrive together after 5 o'clock in the evening in less than 45 minutes is therefore = 1012.5 / 3600 = 9/32
