Nikita invests $2,000 into a bank account with a 4% annual interest rate. In seven years, which is the most expensive item she could afford to buy?
Answer:
Most expensive thing she can afford after 7 years is of worth 2560$
Explanation:
We need to calculate the interest on $2000 at 4% interest per year after 7 year(s).
The formula we'll use for this is the simple interest formula, I = P*r*t, I is the interest after t years, r is interest rate and P is the invest amount.
P = 2000$, r = 4/100 = 0.04, t = 7 years
So , I = 2000* 0.04 * 7 = 560$
Total amount she can retrieve from bank = P+I = 2000 + 560 = 2560$
Most expensive thing she can afford after 7 years is of worth 2560$

Triangle ABC and triangle CDE are similar right triangles. Which proportion can be used to show that the slope of AC is equal to the slope of CE?
A) 0 − 2 / 3 − 0 = 2 − 4 / 6 − 3
B) 2 − 0 / 3 − 0 = 4 − 2 / 6 − 3
C) 2 − 0 / 3 − 0 = 4 − 2 / 3 − 6
D) 2 − 0 / 0 − 3 = 4 − 2 / 6 − 3
Answer: B) [tex]\frac{2-0}{3-0}=\frac{4-2}{6-3}[/tex]
Step-by-step explanation:
1. You can calculate the slope by applying the following formula:
[tex]m=\frac{y_{2}.y_{1}}{x_{2}-x_{1}}[/tex]
2. The point A is (0,0) and the point C is (3,2).
Where:
[tex]y_{2}=2\\y_{1}=0\\x_{2}=3\\x_{1}=0[/tex]
3. The point C is (3,2) and the point E is (6,4).
Where:
[tex]y_{2}=4\\y_{1}=2\\x_{2}=6\\x_{1}=3[/tex]
4. Then, you have:
[tex]\frac{2-0}{3-0}=\frac{4-2}{6-3}[/tex]
[tex]\frac{2}{3}=\frac{2}{3}[/tex]
5. Therefore, the slope of AC is equal of the slope CE.

Graph y = -4x2 - 2 and its inverse
Solve for x.
23=7/9(6x−36)+9
Step 1. Simplify 7/9(6x - 36) to 7(6x - 36)/9
23 = 7(6x - 36)/9 + 9
Step 2. Factor out the common term
23 = 7 * 6(x - 6)/9 + 9
Step 3. Simplify 7 * 6(x - 6) to 42(x - 6)
23 = 42(x - 6)/9 + 9
Step 4. Simplify 42(x - 6)/9 to 14(x - 6)/3
23 = 14(x - 6)/3 + 9
Step 5. Subtract 9 from both sides
23 - 9 = 14(x - 6)/3
Step 6. Simplify 23 - 9 to 14
14 = 14(x - 6)/3
Step 7. Multiply both sides by 3
14 * 3 = 14(x - 60
Step 8. Simplify 14 * 3 to 42
42 = 14(x - 6)
Step 9. Divide both sides by 14
42/14 to x - 6
Step 10. Simplify 42/14 to 3
3 = x - 6
Step 11. Add 6 to both sides
3 + 6 = x
Step 12. Simplify 3 + 6 to 9
9 = x
Step 13. Switch sides
x = 9
Final answer:
The solution to the equation is x = 9.
Explanation:
To solve for x, we need to isolate it on one side of the equation.
Let's start by distributing 7/9 to the terms inside the parentheses:
23 = (7/9)(6x - 36) + 9
Next, simplify the expression inside the parentheses:
23 = (7/9)(6x) - (7/9)(36) + 9
Now, multiply 7/9 with 6x and 36:
23 = (42/9)x - (252/9) + 9
Simplify the fractions:
23 = (14/3)x - (28/1) + 9
Combining the constants:
23 = (14/3)x - 19
Add 19 to both sides:
23 + 19 = (14/3)x
Now we have:
42 = (14/3)x
To isolate x, divide both sides by 14/3:
42 / (14/3) = x
Simplify the expression:
42 * (3/14) = x
Now, calculate:
x = 9

The fractions in this equation are 3/4 and 5/6. The denominators of those fractions are 4 and 6. The lowest common multiple (LCM) of the numbers 4 and 6 is 12. The LCM is 12 because this is the smallest multiple 4 and 6 have in common
Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, ....
Multiples of 6 are: 6, 12, 18, 24, 30, 36, 42, 48, ....
The LCM has been highlighted in bold to make it easier to spot
Therefore, the LCD (lowest common denominator) of the fractions is 12. If we were to multiply both sides of this equation by the LCD, then we will clear out the fractions entirely to have whole numbers only left over.

The figure above the x-axis is the preimage. The figure below the x-axis is the image. Which transformation produced the image?
Answer:
Transformation : [tex](x,y)\rightarrow (x,-y)[/tex]
Step-by-step explanation:
We are given pre-image is above x-axis abd original figure below x-axis.
As we know y-axis below x-axis always negative. When we translate about x-axis only y value of each coordinate change.
x-coordinates remain same.
Best transformation for below x-axis to above x-axis would be [tex](x,y)\rightarrow (x,-y)[/tex].
For example, (2,-3) change to (2,3)
This is valid to all types of figures which form below x-axis.

Jeremiah paid $29.52 for a pair of boots that were on sale. The original price of the boots was $36.00. Enter the percentage discount for the cost of the boots.
Remark
The key to this question is to get the original price (36) down to 29.52. In other words, what % will when multiplied by 36 will result in 29.52?
Solution
36 * (x/100) = 29.52 Multiply both sides by 100
36 * x = 29.52 * 100 The 100 on the left disappears.
36 * x = 2952 The decimal disappears. Divide by 36
x = 2952/36
x = 82%
That is not your answer. That just tells you what % of 36 is that would give 29.52
Answer
The % discount is 100 - 82 = 18%. That is the % discount.
Final answer:
The percentage discount on the boots is calculated by first finding the discount amount ($6.48) and then dividing it by the original price ($36.00), which gives us an 18% discount.
Explanation:
To calculate the percentage discount on the boots, we must first determine the amount of the discount. The discount is the difference between the original price and the sale price, which is $36.00 - $29.52 = $6.48.
Next, we calculate the percentage discount using the formula:
Percentage Discount = (Discount ÷ Original Price) × 100%
Substituting in our numbers:
Percentage Discount = ($6.48 ÷ $36.00) × 100%
Percentage Discount = 0.18 × 100%
Percentage Discount = 18%
So, Jeremiah received an 18% discount on the boots.

what is 5c + 12d - 6 ?
(simplifying algebraic expression)
The algebraic expression '5c + 12d - 6' cannot be simplified without knowing the values of the variables 'c' and 'd'. With specific values, you will be able to simplify the expression. For example, if c is 2 and d is 3, the expression simplifies to 40.
Explanation:The expression given, 5c + 12d - 6, is an algebraic expression which consists of variables, constants, and operations. Here, the variables are 'c' and 'd', the constants are 5, 12 and -6, and the operations are addition and subtraction.
In order to simplify this expression, we should know the values of the variables. Without knowing the specific values of 'c' and 'd', the expression 5c + 12d - 6 cannot be simplified any further.
Let me explain with an example. If 'c' is 2 and 'd' is 3, you would replace the variables 'c' and 'd' in the expression with their given values. This would give: 5(2) + 12(3) - 6 = 10 + 36 - 6 = 40. But without specific values for 'c' and 'd', the expression remains as 5c + 12d - 6.

Catherine 168 pieces of gum playing at a bean bag toss in the county fair at school she gave three to every student in her math class she has 8 remaining how many students are in her class
Givens
Let the number of students in the class be x
Let the number of pieces of gum she gave out be 3x
Equation
3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.
3(x - 1) + 8 = 168 This doesn't work either.
Well we have to choose. It's a rounding problem.
3x + 8 = 168 Subtract 8 from both sides.
3x = 168 - 8 Combine
3x = 160 Divide by 3 on both sides.
x = 160 / 3
x = 53.333333333
Since that can't be, we could say there were 53 students.
