Answer:
x = - 5 , x = 7
Step-by-step explanation:
to find the zeros, let y = 0 , that is
x² - 2x - 35 = 0
consider the factors of the constant term (- 35) which sum to give the coefficient of the x- term (- 2)
the factors are - 7 and + 5 , since
- 7 × + 5 = - 35 and - 7 + 5 = - 2 , then
x² - 2x - 35 = (x - 7)(x + 5) = 0
equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 7 = 0 ⇒ x = 7

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 5 to 8. If there were 9854 total votes, how many no votes were there?
There were approximately 6056 no votes.
Let's assume the number of yes votes is represented by the variable "5x," where x is a positive constant.
Similarly, the number of no votes can be represented by "8x" since the ratio of yes votes to no votes is 5 to 8.
The total number of votes is given as 9854, so we can set up the following equation:
\(5x + 8x = 9854\)
Combining like terms, we have:
\(13x = 9854\)
To solve for x, we divide both sides of the equation by 13:
\(x = \frac{9854 }{13}\)
\(x \approx 757.23\)
Since x represents a positive constant, we round it to the nearest whole number, giving us x = 757.
Now, we can find the number of no votes by multiplying x by the ratio of no votes:
No votes \(= 8x\)
\(= 8 \times 757\)
\(= 6056\)
Therefore, there were approximately 6056 no votes.

The graphs below have the same shape. What is the equation of the blue
graph?
A) g(x) = (x-4)^2
B) g(x) = (x+4)^2
C) g(x) = x^2 + 4
D) g(x) = x^2 - 4
The graphs of f(x) and g(x) are related by transforming one of the two graphs.
The equation of the blue graph is \(\mathbf{g(x) =(x - 4)^2}\)
From the graphs, we have:
\(\mathbf{f(x) =x^2}\)
f(x) is transformed to the right by 4 units.
The rule of this transformation is:
\(\mathbf{g(x) \to f(x - 4)}\)
So, we start by calculating f(x - 4)
Given that:
\(\mathbf{f(x) =x^2}\)
Substitute x - 4 for x in f(x)
\(\mathbf{f(x - 4) =(x - 4)^2}\)
Also, recall that:
\(\mathbf{g(x) \to f(x - 4)}\)
So, we have:
\(\mathbf{g(x) =(x - 4)^2}\)
Hence, the equation of g(x) is \(\mathbf{g(x) =(x - 4)^2}\)

What is the meaning of "\( \mathbb{N}=\bigcap \left \{X:X inductive \right \}\)"?
The meaning of \(\( \mathbb{N}=\bigcap \left \{X:X inductive \right \}\) is that the set of natural numbers is the intersection of all inductive sets.
What does the set show ?The set of natural numbers is inductive because it satisfies both of these conditions. The set is non-empty because it contains the number 1. And if x is a natural number, then x+1 is also a natural number.
In other words, a set is inductive if it satisfies the following two conditions:

The first day the members paid $60 for transportation plus $20 per ticket to the planetarium. The second day they paid $100 for transportation plus $17 per ticket to the geology museum. Write an expression to represent the total cost in dollars for two days for the n members of the club.
Here, we want to represent the total cost for the two-day field trip of the science club. if we let x be the number of members in the club, We then come up with the following expressions
For day 1: $60+$20x
For day 2: $100+$17x
Therefore, the cost of c for the two-day field trip is just the sum of equations 1 and 2 that is,
C= Cost for day 1 + cost for day 2
C= $60+ $20x + $100+ 17x
combine like terms to get
$80+$117x
Ringani worked overtime to raise a total amount R30 000.00 to settle his student debt. If he has deposited R8 500.00 yearly into an account earning 7,04% interest per year compounded annually. How long, rounded to one decimal place did it took her to accumulate the total amount? A. 3.0 years B. 2.4 years C. 2.8 years D. 2.0 years
It took Ringani 2.8 years to accumulate the total amount of R30,000.00 by depositing R8,500.00 yearly into the account with a 7.04% interest rate Compounded annually.The correct answer choice is C. 2.8 years.
To determine how long it took Ringani to accumulate the total amount of R30,000.00 by depositing R8,500.00 yearly into an account with a 7.04% interest rate compounded annually, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the final amount
P is the principal amount (initial deposit)
r is the interest rate (in decimal form)
n is the number of times the interest is compounded per year
t is the time in years
In this case, we have:
P = R8,500.00
A = R30,000.00
r = 7.04% = 0.0704 (in decimal form)
n = 1 (compounded annually)
We want to find the value of t.
Using the formula, we can rearrange it to solve for t:
t = (log(A/P)) / (n * log(1 + r/n))
Substituting the given values, we have:
t = (log(30,000/8,500)) / (1 * log(1 + 0.0704/1))
Calculating this using a calculator, we find that t is approximately 2.8 years.
Therefore, it took Ringani approximately 2.8 years (rounded to one decimal place) to accumulate the total amount of R30,000.00 by depositing R8,500.00 yearly into the account with a 7.04% interest rate compounded annually.
The correct answer choice is C. 2.8 years.
