Answer:
X = 73.448
Step-by-step explanation:
First you have to multiply 1.645 by 2.4 to get rid of 2.4 on the right side of the equation. Then you should have 3.948 = x - 69.5. After that all you have to do is add 69.5 to 3.948 then you have x.

Triangle DHS has the coordinates D(-5, 1), H(-4, 5) and S(-1, 2). What are the coordinates of D'H'S' if DHS is translated 2 units right and 1 unit down?
The new coordinates after translating 2 units right and 1 unit down are D'(-3,0), H'(-2,4) and S'(1,1) respectively.
Given, triangle DHS has the coordinates D(-5, 1), H(-4, 5) and S(-1, 2). Now, we have to find the coordinates of D'H'S' if DHS is translated 2 units right and 1 unit down.
A translation is a transformation that occurs when a figure is moved from one location to another location without changing its size, shape or orientation. In the coordinate plane we can draw the translation if we know the direction and how far the figure should be moved.
To translate the point P(x,y), 'a' units right and 'b' units down, use P′(x+a,y-b).
Now, let's proceed to solve the question according to above listed points accordingly.
D(-5, 1), H(-4, 5) and S(-1, 2), these coordinates are translated 2 units right and 1 unit down. So, we will simply add 2 to the x-coordinate of the points and will subtract 1 from the y-coordinate.
Let's translate D, H and S accordingly into D', H' and S'.
D(-5,1)⇒ D(-5+2, 1-1)⇒ D'(-3,0)
H(-4,5)⇒ H(-4+2, 5-1)⇒ H'(-2,4)
S(-1,2)⇒ S(-1+2, 2-1)⇒ S'(1,1)
Therefore, the new coordinates after translation are D'(-3,0), H'(-2,4) and S'(1,1) respectively.

f(x) = [tex]\frac{x-9}{6x+6}[/tex]
Find an equation for the tangent line to the graph of f at x= 11.
Tangent line: y = ??
The equation of the line tangent to the curve at x = 11 is y = (5 / 432) · x - 43 / 432.
What is the equation of the line tangent to a given curve?
Herein we have a rational function, of which we must derive the equation of the line tangent to the curve at a given point. First, find the first derivative of the function by derivative rules:
f'(x) = [(6 · x + 6) - 6 · (x - 9)] / (6 · x + 6)²
f'(x) = 60 / (6 · x + 6)²
Second, evaluate the first derivative of the function:
f'(11) = 60 / (6 · 11 + 6)²
f'(11) = 5 / 432
This value represents the slope of the tangent line.
Third, calculate the y-value of the curve:
f(11) = (11 - 9) / (6 · 11 + 6)
f(11) = 1 / 36
Fourth, determine the intercept of the tangent line:
b = 1 / 36 - (5 / 432) · (11)
b = - 43 / 432
The equation of the line tangent to the curve at x = 11 is y = (5 / 432) · x - 43 / 432.

A student has a savings account earning 3% simple interest. She must pay $1200 for first-semester tuition by September 1 and $1200 for second-semester tuition by January 1. How
much must she earn in the summer (by September 1) to pay the first-semester bill on time and still have the remainder of her summer earnings grow to $1200 between September 1
and January 1? (Round your answer to the nearest cent.)
Using simple interest, it is found that she needs to earn $2,391.07 during the summer.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
A(t) = A(0)(1 + rt)
In which:
A(0) is the initial amount.r is the interest rate, as a decimal.For this problem, the objective is to have $1200 in 3 months = 0.25 years, hence the parameters are given as follows:
A(0.25) = 1200, t = 0.25, r = 0.03.
Hence we have to solve for A(0):
A(0)(1 + 0.03 x 0.25) = 1200
A(0) = 1200/(1 + 0.03 x 0.25)
A(0) = $1,191.07.
She also needs to earn $1,200 to pay the first-semester bill on time, hence:
1200 + 1191.07 = $2,391.07.
She needs to earn $2,391.07 during the summer.

Bank A charges a monthly service fee of $5.00 and a per-check fee of $0.15,
B while Bank B charges a monthly service fee of $2.50 and a per-check fee of
$0.35. Which of these numbers of monthly checks will cause Bank A to
charge less in fees than Bank B?
for 5 monthly checks, both banks charge the same amount.
for x < 5, Bank B charges less.
for x > 5, Bank A charges less.
For what numbers of monthly checks will Bank A charge less than Bank B?Bank A charges a fixed fee of $5.00 plus $0.15 per-check fee.
So, if you do x monthly checks, Bank A will charge you:
A(x) = $5.00 + $0.15*x
Bank B charges a service fee (fixed) of $2.50 plus $0.35 per check, then for x monthly checks they charge:
B(x) = $2.50 + $0.35*x
Both banks will charge the same amount when:
A(x)= B(x)
So we need to solve the linear equation:
$5.00 + $0.15*x = $2.50 + $0.35*x
$5.00 - $2.50 = $0.35*x + $0.15*x
$2.50 = $0.50*x
$2.50/$0.50 = x = 5
So, for 5 monthly checks, both banks charge the same amount.
for x < 5, Bank B charges less.
for x > 5, Bank A charges less.

B. (-2,-2)

Step-by-step explanation:
x - y = 0 ( add y to both sides )
x = y → (1)
6x + 5y = - 22 → (2)
substitute x = y into (2)
6y + 5y = - 22
11y = - 22 ( divide both sides by 11 (
y = - 2
since x = y then x = - 2

Stanley analyzes the table of values for a polynomial function. He has determined through applying Descartes’ rule of sign that there is 1 negative real zero, and either 1 or 3 positive real zeros. He has also determined that the upper bound of the function is 3.
a) The degree of the polynomial function is 4
b) The positive real zeros does the function have are 3
a. The degree of the polynomial is equal to the sum of the real and complex zeros. There are four total zeros in the sum (1 negative real) + 3 positive real/complex). The polynomial has a degree of 4.
The solution to part b and the end-behavior, which tends to - for |x|, both support the even degree.
b. The intermediate value theorem informs you that, given the numbers in the table, there will be zeros in the intervals (0, 1), (1, 2), and (2, 3). Within certain time periods, the function's sign changes. Thus, there are three genuine positive zeros.
By examining the table of function values, Stanley is unable to infer anything about Descartes' rule of signs.

The number of panels from plant B that were produced if the overall percentage of the defective panels from two planet were 7% is 9000 panels.
How to Solve Algebra Word Problems?
We are given;
Number of TV panels to be produced = 9000 panels
Percentage of panels from plan A that were defective = 3%
Percentage of panels from plan B that were defective = 10%
Let n represent the number of panels from plant B.
Thus, we can write the algebraic equation as:
0.1(9000) + 0.03(n) = 0.07(9000 + n)
900 + 0.03n = 540 + 0.07n
900 - 540 = 0.07n - 0.03n
0.04n = 360
n = 360/0.04
n = 9000 panels

Step-by-step explanation:
You want a point-slope equation of the line through points (-8, 2) and (6, 8).
SlopeThe slope of the line is given by the formula ...
m = (y2 -y1)/(x2 -x1) . . . . . . where (x1, y1) and (x2, y2) are points on the line
Using the given points, we find the slope to be ...
m = (8 -2)/(6 -(-8)) = 6/14 = 3/7
Point-slope equationThe equation of a line with slope m through point (h, k) is written in point-slope form as ...
y -k = m(x -h)
Here, we have m=3/7, and (h, k) = (-8, 2). This means the equation of the line is ...
