Answer:
Sarah has $18, and Lance has $42.
Step-by-step explanation:
We know that Sarah and Lance together have $60, so we can write the equation:
S + L = 60
We also know that Lance has six more than twice as much as Sarah, which can be expressed as:
L = 2S + 6
Now, we have a system of two equations:
S + L = 60
L = 2S + 6
We can use substitution or elimination to solve this system. Let's use substitution:
From equation 2, we can express L in terms of S:
L = 2S + 6
Now, substitute this expression for L into equation 1:
S + (2S + 6) = 60
Combine like terms:
3S + 6 = 60
Subtract 6 from both sides:
3S = 60 - 6
3S = 54
Now, divide by 3:
S = 54 / 3
S = 18
So, Sarah has $18.
Now, we can find Lance's amount using equation 2:
L = 2S + 6
L = 2(18) + 6
L = 36 + 6
L = 42
Lance has $42.
3/6 = k /18
Compound interest is the addition of interest. The interest that is needed to be paid by Jim in the 4 years of tenure is $2253.98.
Compound interest is the addition of interest on the interest of the principal amount. It is given by the formula,
We know that the Principal amount received by Jim is $2000, while the interest that Jim needs to pay is 3% quarterly, therefore, he needs to pay the interest 4 times a year. Thus, the value of n is 4.
Now, we know all the values therefore, substitute the values in the formula of compound interest,
Hence, the interest that is needed to be paid by Jim in the 4 years of tenure is $2253.98.

Answer:
$2253.98
Step-by-step explanation:
Jim received a $2000 loan from his bank. The loan accrues 3% interest every 3 months.
P=2000
r= 3%=0.03 and t= 4 years
interest every 3 months so n= 4
Answer:
78
Step-by-step explanation:
If t=4
18+t2 would equal “26”
Then 26x3 would be “78”
When t = 4, the part of the equation 18 + t^2 evaluates to 34. We cannot compute - 5x^3 without the value of x.
The subject of the question is Mathematics, more specifically, the topic of algebraic expressions. Given an equation, 18 + t^2 - 5x^3, you'd like to find the value when t = 4. However, the value of x is not provided which is required to fully solve this expression. If we ignore the variable x, and only substitute the value of t in the expression, it will be:
18 + 4^2 = 18 + 16 = 34.
So, when t = 4, the part of the equation 18 + t^2 evaluates to 34. However, we cannot calculate - 5x^3 without having the value of x.

y = (x - 4)² + 4
or y = x² - 8x + 20
Transformation of a graph is changing the shape and location of a graph.
There are four types of transformation geometry: translation (or shifting), reflection, rotation, and dilation (or stretching).
In general, given the graph of y = f(x) and v > 0, we obtain the graph of:
That's the vertical shift, now the horizontal one. Given the graph of y = f(x) and h > 0, we obtain the graph of:
Hence, the combination of vertical and horizontal shifts is as follows:
The plus or minus sign follows the direction of the shift, i.e., up-down or left-right
Given:
In the graph, notice the shifting of the vertex from (0, 0) to (4, 4).
From this, we can describe that from g(x) to f(x) there has been a shift to the right 4 units and upward 4 units.
Let us construct f(x) from g(x).
We set h = -4 and v = +4 and we get the equation f(x) as
Let's expand it if we want to represent a standard form of a quadratic function, like this:
Conclusion
The graph of f(x) is drawn by the combination of shifting the graph of g(x) to the right 4 units and upward 4 units.
