After withdrawing $40 from a checking account with a balance of -$30, Selene's checking account balance becomes -$70.
Explanation:Selene's checking account balance is initially at -$30. When she withdraws an additional $40, the balance goes further negative.
To find Selene's checking account balance after the withdrawal, we need to subtract the withdrawal amount from the initial balance. Her initial balance is -$30, and she withdrew $40 more.
To find the new balance, you subtract $40 from -$30.
Account Balance Calculation:
Start with the initial balance: -$30.Subtract the withdrawal: -$30 - $40.Calculate the new balance: -$70.Therefore, Selene's checking account balance after the withdrawal is -$70.
Final answer:
After withdrawing an additional $40 from an initial balance of -$30, Selene's checking account balance is -$70.
Explanation:
Selene's checking account balance after the withdrawal can be determined by subtracting the amount withdrawn from her initial balance. She starts with a balance of -$30. After withdrawing an additional $40, the new balance can be calculated as follows:
Initial balance: -$30
Withdrawal: -$40
New balance: -$30 - $40 = -$70
Thus, Selene's checking account balance after the withdrawal is -$70.

B) (x, y) → (x − 2, y + 5)
C) (x, y) → (x + 2, y − 5)
D) (x, y) → (x − 2, y − 5)
Answer:
D
Step-by-step explanation:
The original figure was was moved 2 units to the left (-2), and 5 units down (-5).
Answer:
D is correct.
Step-by-step explanation:
In the given figure two rectangle MNOP and M'N'O'P'
To choose correct transformation rule from MNOP to M'N'O'P'
So, we change for point M
M(-2,3) → M'(-4,-2)
If shift M 2 unit left
M(-2,3) → M(-2-2,3)
Now, shift 5 unit down
M(-2-2,3) → M(-4,-2) ⇔M'(-4,-2)
So,
(x,y) → (x-2,y-5)
Rule: (x,y) → (x-2,y-5)
Using this rule get MNOP to M'N'O'P'

ANSWERS PLEASE!
Without explicit graphical representation, precise classification is challenging. Tentatively: Graph A could be a non-linear function, Graph B is not a function due to its circular form, and Graph C could be a linear function (or a piecewise linear function) as a 'V' indicates straight lines.
Explanation:In Mathematics, when we talk about functions, a linear function is one where the graph is a straight line. A non-linear function is anything that is not a linear function, including any graph that is not a straight line. If a graph does not pass the vertical line test, where any vertical line would touch the graph only once, it is considered not a function.
Based on the descriptions given:
Graph A, being the 'first graph,' isn't sufficient information for classification. However, as a placeholder, let's say it's a non-linear function.Graph B, being a circle, does not pass the vertical line test and is therefore not a function.Graph C, if shaped like a 'V,' would be a linear function, as it forms straight lines. However, if the point at which the 'V' changes direction occurs at a single point, it could be argued as a piecewise linear function.Learn more about Function Identification here:https://brainly.com/question/33409105

If x isn’t divisible by 4, then x isn’t divisible by 2. C. If x isn’t divisible by 2, then x isn’t divisible by 4. D. If x is divisible by 2, then x isn’t divisible by 4. E. If x isn’t divisible by 4, then x is divisible by 2.
Answer:
B. If x isn’t divisible by 4, then x isn’t divisible by 2.
Step-by-step explanation:
contra positive statement is obtained by interchanging the hypotheses and conclusion of the inverse statement.
Here given that statement p is
If x is divisible by 4, then x is divisible by 2.
To write contrapositive of p, first we interchange the hypothesis.
Then it would look like
If x is divisible by 2, then x is divisible by 4.
Now we make conclusion as negative. i.e.
If x is not divisible by 4, then x is not divisible by 2.
This is the contra positive statement of p
Hence option B is right.

At which point on the graph are resources not used efficiently?
A) point A
B) point F
C) point X

Answer:
D
Step-by-step explanation:
A production possibilities curve shows the maximum amount of 2 goods that can be produced given the input is fixed.
The points that lie on the curve gives different combinations of output of 2 goods given that resources shifts from one to another.The point outside the curve are impossible combination because with current resources, this much of both goods cannot be produced.The point inside the curve shows inefficient use of resources because more could be produced of each good given the resources.So the point which uses resources inefficiently is the one inside the curve, which is Y.

Answer:
x = 2.5 inches. Or
x = 5/2
Step-by-step explanation:
Length: 7 + 2x
Width: 5 + 2x
Note that you have to add x at each end of the picture and onto each part of the width.
The entire area is 120 square inches.
Formula
L*W = Area
(2x + 7)(2x + 5) = 120
Solution
4x^2 + 10x + 14x + 35 = 120 Subtract 120 from both sides. Add xs
4x^2 + 24x + 35 - 120 = 0
4x^2 + 24x - 85 = 0 Factor

In a certain year the price of gasoline rose by 20% during January, fell by 20% during February, rose by 25% in March, and fell by x% in April. The price of gasoline at the end of April was the same as it had been at the beginning of January. Find the value of x.
Answer: The value of x is [tex]\frac{50}{3}[/tex]
Step-by-step explanation:
Let the original price of gasoline be y
Since we have given that
Price of gasoline rose by 20% during January fell by 20% during February rose by 25% in March and fell by x% in April.
So, According to question,
In January, Price became
[tex]\frac{100+20}{100}\times y=\frac{120}{100}\times y=\frac{6}{5}\times y=\frac{6y}{5}[/tex]
Similarly, In February, Price became
[tex]\frac{100-20}{100}\times \frac{6y}{5}=\frac{80}{100}\times \frac{6y}{5}=\frac{4}{5}\times \frac{6y}{5}=\frac{4}{5}\times \frac{6y}{5}=\frac{24y}{25}[/tex]
Similarly, in March, Price became,
[tex]\frac{100+25}{100}\times \frac{4\times 6y}{25}=\frac{125}{100}\times \frac{6\times 4y}{25}=\frac{5}{4}\times \frac{24y}{25}=\frac{5}{4}\times \frac{24y}{25}=\frac{6y}{5}[/tex]
similarly, in April , Price became,
[tex]\frac{100-x}{100}\times \frac{6y}{5}[/tex]
so, we have given that the price of gasoline at the end of April was the same as it had been at the beginning of January.
So, it becomes,
[tex]\frac{6y}{5}\times \frac{100-x}{100}=y\\\\6(100-x)=500\\\\600-6x=500\\\\600-500=6x\\\\100=6x\\\\x=\frac{100}{6}=\frac{50}{3}[/tex]
Hence, the value of x is [tex]\frac{50}{3}[/tex]
Answer:
x= 16 2/3
Step-by-step explanation:
Price will be p
The price in January increases by 20%, it will be 6p/5. The price in February decreased by 20%, it becomes 24p/25. The price in March rose by 25%, it will be 6y/5.
April: 6y/5 times 100-x/100 = p 6(100-x)=500 100=6x x= 16 2/3

In parallelogram ABCD , diagonals AC¯¯¯¯¯ and BD¯¯¯¯¯ intersect at point E, AE=x2−16 , and CE=6x . What is AC ? Enter your answer in the box.
Answer:
AC = 96 units.Step-by-step explanation:
Given ABCD is a parallelogram.
And diagonals AC and BD intersects at point E.
Note: Diagonals of a parallelogram intersects at mid-point.
E is the mid point of diagonal AC
Therefore,
AE = CE.
Plugging expression for AE and CE, we get
[tex]x^2-16 =6x.[/tex]
Subtracting 6x from both sides, we get
[tex]x^2-16-6x = 6x-6x[/tex]
[tex]x^2 -6x -16 =0[/tex]
Factoring quadratic
(x+2)(x-8) =0.
x+2 =0 => x=-2.
x-8=0 => x=8.
We can't take the length by a negative number. Therefore, x=8.
Now, plugging x= 8 in CE =6x, we get
CE = 6(8) = 48.
We need to find the length of AC.
AC would be two times of CE.
Therefore, AC = 2 × 48 = 96.

luz will buy a total of $9360 on her car loan. her monthly payment is $390. for how many months is the loan
Luz will have to pay $390 per month for 24 months to repay her $9360 car loan in full.
Explanation:To determine how many months Luz will need to pay for her car loan, we can use a simple division since the question doesn't mention anything about interest rates affecting the payments.
We divide the total loan amount she has to pay, which is $9360, by her monthly payment of $390.
Months to pay off the loan = Total loan amount ÷ Monthly payment
Months = $9360 ÷ $390
Months = 24
Luz will therefore have to make payments for 24 months to repay her car loan in full.

Answer:
2. Circumcenter is (-2, 1)
4. Orthocenter is (5, 0)
6. II ∠DOS and ∠CAT are vertical and III ∠DOS and ∠CAT are adjacent
8. m∠PBC = 30°
10. KV, VM, KM
12. DC is greater
14. x = 12
Step-by-step explanation:
2. Equation of the perpendicular bisector of AB is x = -2 and the equation of the perpendicular bisector of BC is y = 1.
Circumcenter is the point of intersection of the perpendicular bisectors of the sides of the triangle.
Hence, circumcentre is (-2, 1).
4. Orthocenter is the point of intersection of the altitudes. Here, AB and BC are two altitudes and B is their point of intersection.
Hence, the orthocenter is (5, 0).
6. Adjacent angles are angles separated by a line and vertical angles are angles vertically opposite to each other.
Hence, statements II and III contradict to each other.
8. If P is equidistant from all the three sides, then P is the center of the in-circle and hence it is the incenter of the triangle.
If P is the incentre, then PB is the internal bisector.
Therefore, ∠PBC = [tex]\frac{1}{2}[/tex] ∠ABC = 30°
10. From the triangle sum property, ∠ M = 180 - (110 + 40) = 30.
Since, the side opposite to the smallest is the shortest, the correct order is:
KV, VM, KM
12. Clearly, ∠ ABD is acute. Therefore, ∠ DBC > ∠ ABD.
Since, side opposite to larger angle is greater, DC is greater.
14. Let the sides of the top triangle be p and q. So, two sides of whole triangle are 2p and 2q.
Now, if we compare the top small triangle and the whole triangle, they are similar by SAS similarity since,
the top angle is common and [tex]\frac{p}{2p}=\frac{q}{2q}=\frac{1}{2}[/tex].
Since, corresponding parts of similar triangles are proportionate,
[tex]\frac{3x}{5x+12} =\frac{1}{2}[/tex]

Batman wanted to check on the population of his enemies. He noticed that initially there were 4 baddies living at Arkham asylum. Batman notices that the population doubled every 2 years. below is the equation that Batman route to predict the population of bad guys in 1992.
y=4(2)^x where x is the number of years and y is the population of bad guys.
Is Batman's equation of this scenario accurate? Explain gow you know
**please help me, i keep getting confused and second guessing myself. Thank you!!! <3**
Answer:
Batman's equation of this scenario is not accurate.
Step-by-step explanation:
The exponential function representing this situation should be
[tex]y=a\cdot b^{nx},[/tex]
where a is the initial amount of baddies living at Arkham asylum, b is the rate at which enemies increased, n is the number determing the period of enemies increasing and x is time in years.
In your case,
a=4 (initially there were 4 baddies living at Arkham asylum),
b=2 (the population doubled),
n=1/2 (the population doubled every 2 years).
Then
[tex]y=4\cdot 2^{\frac{x}{2}}.[/tex]
Note then when considering the function [tex]y=4\cdot 2^x[/tex] the population dubled each year, not every 2 years.
Batman's equation y=4(2)ˣ correctly models the doubling population of bad guys every 2 years. It uses an exponential growth formula that accurately calculates the population for any given 2-year period.
Yes, Batman's equation y=4(2)ˣ accurately represents the scenario of the population of bad guys doubling every 2 years. The equation follows an exponential growth model, where the initial population is 4, and it doubles with each increment of x, representing a 2-year interval. Therefore, for any given value of x (the number of 2-year intervals since the initial count), the equation will yield the correct population size.
To further illustrate, after the first 2-year interval (x=1), the population would be y=4(2)¹=8, which is double the initial population. After the second 2-year interval (x=2), the population would be y=4(2)²=16, continuing the pattern of doubling.

Answer:
5'3
Step-by-step explanation:
This question will look like this: 18/12 x/3.5. Remember about height/shadow.
You will need to cross multiply 18 and 3.5 and keep 12, x as 12x.
Now it will look like this: 12x=63. Divide that 63 with 12 and you will get 5.25.
Since there is a 5 next to that 2 you add 1 because 5 or higher add one and 5 or lower don't add anything.
You got rid of that 5 and added 1 to the 2, you will have 5'3

what two consecutive numbers that square root of 101 lies between
The square root of 101 lies between 10 and 11, as 101 falls between the perfect squares of these two numbers (100 and 121, respectively).
Explanation:The square root of 101 is a value which, when multiplied by itself, results in 101. In order to find which two consecutive numbers this square root lies between, we need to consider which two perfect squares it falls between. The perfect squares closest to 101 are 100 (which is 10^2) and 121 (which is 11^2). Therefore, the square root of 101 lies between the numbers 10 and 11.
