<5=61°What's the X-Intercepts of (2x-5)(x+1)=9 or (2x-5)(x+1)-9
Answer:
Step-by-step explanation:
Either way works. It comes to the same thing.
(2x-5)(x+1)=9
F: 2x*x = 2x^2
O: 2x*1 = 2x
I: -5 * x = -5x
L: -5*1 = -5
2x^2 + 2x - 5x - 5 = 9 Subtract 9 from both sides
2x^2 - 3x - 14 =0 Divide by 2 (it makes life easier).
Factoring you get
(2x - 7)(x + 2)
2x - 7 = 0
2x = 7
x = 3.5
x + 2 = 0
x = -2
The x intercepts = (3.5,0) and (-2,0)

7. Sorav bought a jacket for Rs. 2500 sold it for Rs. 1900. Find her loss.
Answer:
600
Step-by-step explanation:
if SP>CP,
It is profit [SP - CP = Profit]
if CP>SP,
It is loss [CP - SP = Loss]
Here in the question CP>SP so,
loss = CP - SP
=2500 - 1900
= 600
Answer:
24
Step-by-step explanation:
C.P=2500
S.P=1900
Here,
Cp>Sp
So,
Loss= cp-sp

What is 10% Compound interest of R15 000 every month for 3 years?
Answer:
19500
Step-by-step explanation:
30/100 X 15000 = 4500
15000 + 4500 = 19500
Answer:
A = $19,965.00
A = P + I where
P (principal) = $15,000.00
I (interest) = $4,965.00
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 15,000.00(1 + 0.1/1)(1)(3)
A = 15,000.00(1 + 0.1)(3)
A = $19,965.00
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $15,000.00 at a rate of 10% per year compounded 1 times per year over 3 years is $19,965.00.

How high is a tree that cast a26ft shadow at the same time a 6ft post casts a shadow which is 11ft long
Answer:
[tex]14\frac{2}{11}[/tex] ft
Step-by-step explanation:
Let the height of the tree equal x. Shadows are proportional to the height of an object, so we can write a proportion where to numerators are the object and the denominators are the shadow:
[tex]\frac{x}{26} =\frac{6}{11}[/tex]
Now, to solve for x, we can cross-multiply:
11x = 6*26
11x = 156
x = [tex]14\frac{2}{11}[/tex]

Cecelia receives two credit card offers in the mail. Each has a 0% introductory APR. After the introductory period, the first card has an APR of 19.99% and the second card has an APR of 24.99%. If each card has a late fee of $35 and an annual membership fee of $25, which card should she choose and why?
Answer:
1. We are told they have similar APR (starting) and Annual fee of 25 and similar late fee of 35
Then we must consider the APR after the initial value 19.999% < 24.99%Hence she should price the first card with a 19.99% APR

Answer:
a(n) = 1/2(-8)^(n-1)
Step-by-step explanation:
The general term of a geometric sequence is ...
a(n) = a(1)×r^(n-1)
where a(1) is the first term, and r is the common ratio.
Here, the first term is a(1) = 1/2. The common ratio is the ratio of any two sequential terms: r = 32/-4 = -8. Then the explicit formula is ...
a(n) = 1/2(-8)^(n-1)

Determine which number is in "proper" scientific notation.
The number that is in "proper" scientific notation is A. 2.31 * 10^-4
What is scientific notation?A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. When a number is too big or too small to be conveniently stated in decimal form, or if doing so would involve writing out an exceptionally long string of digits, it can be expressed using scientific notation. It is also known as standard form in the scientific form, standard index form, and standard form.
The number on the left in scientific notation always consists of a single digit, a decimal point, and the appropriate (see important figures) number of digits after the decimal.

A good doctor recommends that a person who weighs 65 pounds be given 200
milligrams of medicine. If the dosage were proportional to a person's weight, how
many milligrams of medicine would the doctor recommend for a person who
weighs 96 pounds?
9514 1404 393
Answer:
295 mg
Step-by-step explanation:
The proportion can be written ...
dose/(96 lb) = (200 mg)/(65 lb)
dose = (96/65)(200 mg) ≈ 295.4 mg . . . . . multiply by 96 lb, cancel lb units
The doctor might recommend 295 mg for a 96-pound patient.
The illustration below shows the graph of y as a function of x.
Complete the sentences below based on the graph of the function.
As x increases, y _____
The rate of change for y as a function of x is ______
therefore the function is_____
For all values of x, the function value y____ 0
The y-intercept of the graph is the function value y=______
When x=6 equals, 6, the function value y=____
As x increases, y increases
The rate of change for y as a function of x is 1.4
therefore the function is growth function
For all values of x, the function value y increases
The y-intercept of the graph is the function value y 1
When x = 6, the function value y = 7.5
How to find the rate of change of for the functionFor an exponential function, the rate of change is b, in the equation
= f(x) = abˣ
From the graph, points (0, 1), and (2, 2) will be used for the calculation
Exponential function is represented by f(x) = abˣ
for x = 0, f(x) = 1
1 = a * b^0
a = 1
for x = 2, f(x) = 2
2 = 1 * b^2
2 = b^2
b = √2 = 1.414
for increasing rate, b = 1 + r
1.41 = 1 + r, r = 41%
When x = 6
= 1 * 1.4^6
