Answer:
Write out all the pairs of numbers which can be multiplied to produce c.
Add each pair of numbers to find a pair that produce b when added.
If b > 0, then the factored form of the trinomial is (x + d )(x + e).
Check: The binomials, when multiplied, should equal the original trinomial.

Cindy is buying a new car and wants to learn how the value of her car will change over time. Insurance actuaries predict the future value of cars using depreciation functions. One such function is applied to the car whose declining value is shown at the right. Write an exponential function for it.
Answer:
[tex]C=10000(0.852)^t[/tex]
Step-by-step explanation:
Let the exponential function be,
[tex]C=a(b)^t[/tex]
Here, C = cost of the car
t = Duration or period in years
From the given table,
Two points representing cost of the car and time are (10000, 0) and (8520, 1),
For (10000, 0),
[tex]10000=a(b)^0[/tex]
a = 10000
For (8520, 1)
8520 = [tex]10000(b)^1[/tex]
[tex]b=\frac{8520}{10000}[/tex]
b = 0.8520
Therefore, exponential equation will be,
[tex]C=10000(0.852)^t[/tex]

Louis wants to buy skis that have a regular price of $328. They have been marked down 25% off the regular price. Louis calculates the new total price including tax.
How much money will Louis save on the total cost because of the markdown?
Answer:
Part ACalculate sale price and add sales tax:
20% off $339 add tax ⇒ $339*0.8*1.085 = $294.25 ≤ $30015% off $310 add tax ⇒ $310*0.85*1.085 = $285.90 ≤ $30025% off $365 add tax ⇒ $365*0.75*1.085 = $297.02 ≤ $30020% off $300 add tax ⇒ $300*0.8*1.085 = $260.40 ≤ $300Each price is acceptable as less than $300
Part BMarkdown with tax added:
25% off $328 add tax ⇒ $328*0.75*1.085 = $266.91Without discount, the price with the tax added:
$328*1.085 = $355.88The difference is the amount Luis has saved:
$355.88 - $266.91 = $88.97The function f(x) has a vertical asymptote at x= [blank].
Answer:
The vertical assymptote is at x = 0
Step-by-step explanation:
Vertical assymptote are simply defined as lines that correspond to the points where the denominator of a rational function is zero.
From the graph, we can see that the curve remains on the y - axis at x = 0
Thus, the vertical assymptote is x = 0

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer:
first step is to add the both angles that are given =78+46
=124
second step is to minus 124 from 180 =180-124
=56 . I used 180 because that is the sum of all the angles in a triangle . so x =56

The graph of y = ½ x2 − x − 4 is shown below. What are the zeros of the quadratic?
Answer:
x = - 2, x = 4
Step-by-step explanation:
The zeros are the values of x on the x- axis where the graph crosses
The graph crosses the x- axis at (- 2, 0 ) and (4, 0 )
Then the zeros are x = - 2 and x = 4

A family wants to remodel a house and spend at most $135,000 total for the entire project. a)If the builder wants to make a 15% profit on the value of the project, what is the largest amount the family can spend on hard costs (materials, labor, engineering, designing, permits) to be able to pay the builder his profit while staying under the $135,000 budget? b)What is the builder's profit? (Hint: You cannot simply take 15% of $135,000 because the $135,000 includes the builder's profit. Just like in our commission problems, you don't make commission on commission. The percentage is applied to the value of goods and services provided.)

Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = -6x - 8
Step-by-step explanation:
Two points on this line are (-3, 10) and (0, -8). Moving from the first to the second, we see that x increases by 3 and y decreases by 18. Thus, the rise and run are -18 and 3 respectively, so that the slope of this line is m = -6.
Adapt the slope-intercept form y = mx + b to this particular situation. Recognize that the given (0, -8) is the y-intercept and that the slope, m, is -6.
The equation of this line is thus
y = -6x - 8

Step-by-step explanation:
i am thinking of a number i multiply by 14 qand add 12 i get the same answer if i multiply by 5 and add 246
Answer:
x = the unknown number = 26
Step-by-step explanation:
Let
x = the unknown number
i multiply by 14 qand add 12
(x * 14) + 12
= 14x + 12
i get the same answer if i multiply by 5 and add 246
(x * 5) + 246
= 5x + 246
Equate both equations
14x + 12 = 5x + 246
14x - 5x = 246 - 12
9x = 234
x = 234 / 9
x = 26
x = the unknown number = 26
