Vertical Line Test - A function's x-values must have only 1 y-value corresponding to it. If the function fails to pass this, it is not a function.Step-by-step explanation:
When we apply the Vertical Line Test to the 1st graph, it does not pass it. Therefore, the 1st graph is not a function.
When we apply the Vertical Line Test to the 2nd graph, it does not pass it. Therefore, the 2nd graph is not a function.
When we apply the Vertical Line Test to the 3rd graph, it does not pass it. Therefore, the 3rd graph is not a function.
When we apply the Vertical Line Test to the 4th graph, it does pass it. Therefore, the 4th graph is a function.

if a+3b=10, what is the value of 2a+6b=?
Answers
Answer:
20
Step-by-step explanation:
2(a+3b)=2(10)
The value of 2a + 6b is 20.
To find the value of 2a + 6b, we can use the given equation:
a + 3b = 10
Now, we want to find 2a + 6b, which is simply twice the value of "a + 3b."
2a + 6b = 2(a + 3b)
Now, substitute the value of "a + 3b" from the given equation:
2(a + 3b) = 2(10)
2a + 6b = 20
So, the value of 2a + 6b is 20.

Suppose that f(x) varies directly with x and f(x)=160 when x = 5.
What is f(x) when x = 0.5?
A: 16
B: 160
C: 32
D: 180
Answers
0.5/5 = 10
160/10 = 16
The required value of f(x) when x = 0.5 is 16.
Given,
f(x) varies directly with x .
f(x)=160 when x = 5.
We have to find f(x) when x = 0.5
According to the question ;
A function f(x) that varies directly with x. Direct variation is a case of variation expresses as the following form:
f(x) = kx
The value k is a nonzero constant greater than zero and is called the constant of variation.
This indicates that f(x) increases as x increases.
So,
f( x ) = kx
[tex]k = \frac{f (x) }{x}\\\\ k = \frac{f(5)}{5}[/tex]
[tex]k = \frac{160}{5}[/tex]
k = 32
When x = 0.5,
Then , f(x) = 32x
f(x) = 32(0.5)
f(x) = 16
The required value of f(x) when x = 0.5 is 16.

Step-by-step explanation:
100 % edmentum
The solutions of the equation are x=-3+√42 and x=-3-√42.
The given quadratic equation is 2x²+12x=66.
What is completing square method?Completing the Square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial.
Now, 2x²+12x=66 can be written as x²+6x-33=0
Add and subtract (b/2)² to the equation.
That is x²+6x-33+9-9=0
⇒x²+6x+9=42
⇒(x+3)²=42
⇒(x+3)=±√42⇒x=±√42-3
Therefore, x=-3+√42 and x=-3-√42.

Answer:
y=7.5x, y=9.25x, y=6x
Step-by-step explanation:
on the first table we have for 2 tikets $ 15 so the price for one ticket (also known as unit price) is 15/2= $ 7.5
the equation for the price of ticket must be
y= 7.5 x (where y is price you pay for x number of tikets)
on the second table you can pick that you have $37 for 4 tikets so unit price is 37/4= $9.25 per one ticket
y=9.25x
last table $12 for 2 tikets so for one ticket is 12/2=$6

Answers
Answer:
The answer is B
Step-by-step explanation:
[-6,2]
The solution to the inequality is [–6, 2]. Then the correct answer is option B.
What is inequality?Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
The inequality is solved as:-
x⁴ + 4x³ ≤ 12x²
x² ( x² + 4x ) ≤ 12x²
x² + 4x ≤ 12
x² + 4x - 12 ≤ 0
x² + 6x - 2x + 12 ≤ 0
Equate the factors to zero.
( x + 6 ) ( x - 2 ) = 0
x =( -6 , 2 )
Hence, the solution is x = ( -6, 2 ).

A chip used in the production of particleboard (Question 4) has a 15% chance of containing excessive bark. What is the probability of having more than 860 bark-free chips in a batch of 1,000
Answers
Answer:
0.2
Step-by-step explanation:
Given that:
P(particleboard with excessive bark) = 0.15
The P(that particleboard do not have excessive bark) = 1 - 0.15
i.e the population proportion number of success p = 0.85
The sample size (n) is given to be = 1000
To find the P(X ≥ 860)
Since the sample size is large, we will apply the normal approximation of binomial distribution to treat this question.
The population mean [tex]\mu = n \times p[/tex]
[tex]\mu = 1000 \times 0.85[/tex]
[tex]\mu =850[/tex]
The population standard deviation [tex]\sigma = \sqrt{n*p(1-p)[/tex]
[tex]\sigma = \sqrt{1000*0.85*(1-0.85)}[/tex]
[tex]\sigma = \sqrt{1000*0.85*(0.15)}[/tex]
[tex]\sigma = \sqrt{127.5}[/tex]
[tex]\sigma = 11.2916[/tex]
Let X be the random variable which obeys a normal distribution;
Then;
[tex]P(X \ge 860) = P(Z\ge \dfrac{x- \mu}{\sigma})[/tex]
[tex]P(X \ge 860) = P(Z\ge \dfrac{860- 850}{11.2916})[/tex]
[tex]P(X \ge 860) = P(Z\ge \dfrac{10}{11.2916})[/tex]
P(X ≥ 860) = P(Z ≥ 0.8856)
P(X ≥ 860) = 1 - P(Z ≤ 0.8856)
From z table
P(X ≥ 860) = 1 - 0.8122
P(X ≥ 860) = 0.1878
P(X ≥ 860) [tex]\simeq[/tex] 0.2
Thus, the probability of having more than 860 bark-free chips in a batch of 1,000 = 0.2
