The equation of line in slope intercept form is,
⇒ y = x - 2
When the graph is shift down 9 units.
Then, Equation of line become,
⇒ y = x - 11
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (2, 0) and (0, -2).
Now,
Since, The equation of line passes through the points (2, 0) and (0, -2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 2 - 0) / (0 - 2)
m = - 2 / -2
m = 1
Thus, The equation of line with slope 1 is,
⇒ y - 0 = 1 (x - 2)
⇒ y = x - 2
And, When the graph is shift down 9 units.
Then, Equation of line become,
⇒ y = x - 2 - 9
⇒ y = x - 11
Therefore, The equation of line in slope intercept form is,
⇒ y = x - 2

Is (x 5) a factor of f(x) = x3 − 4x2 3x 7? explain your reasoning.
(x+5) is not a factor of f(x) because x = -5 does not satisfy the given equation f(x) = x³ - 4x² + 3x + 7.
Step 1. First we solve the equation x +5 = 0, we get
x = -5
Step 2. By putting the value of x = -5 in f(x) check whether we get a zero or a number other than zero.
If we get zero then x+5 is a factor of f(x) and if we get a number other than zero then x+5 is not a factor of f(x)
f(-5) = (-5)³ − 4(-5)² + 3(-5) + 7 = - 233
Since we got -233 and not 0. Therefore, (x+5) is not a factor of f(x).

Given,
The cost of an online newspaper is 7.99
And if we bought the one year subscription the cost is 89.88
Let the the cost of the each month if we bought the one year subscription be x .
for one year the cost is 89.88
for one month could be
that is, x = 89.88/12

A point in the figure is selected at random. Find the probability that the point will be in the part that is NOT shaded.
A. about 25%
B. about 20%
C. about 10%
D. about 5%
Answer:
About 20%
Step-by-step explanation:
The probability of a point on the un-shaded region will be given by;
Area of the shaded region/total area
Considering that the circles are of the same size, then the length of the square is 2d
Area of the square = 4d²
Area of the shaded = (4d² -4π(d/2)²
= 4d² -πd², but π = 22/7
= 6/7d²
Probability = (6/7d² ÷ 4d²) × 100%
= (6/28 d²) × 100%
= 21.42 %

Algebraically determine the inverse of the function f(x)= 12x2+5.
Answer:
Step-by-step explanation:
f(x)= 12x2+5 should be written as f(x) = 12x^2 + 5; the " ^ " symbol signifies exponentiation and is mandatory.
Here's how we find the inverse function.
1. Apply the horizontal line test. if a horizontal line intersects the graph in more than one place, the function is not one-to-one and does not have an inverse for all x. However, if we focus on only [0, infinity), this part of the graph does have an inverse, which we can find as follows:
2. Replace 'f(x)' with 'y: y = 12x^2 + 5
3. Interchange x and y: x = 12y^2 + 5
x - 5
4. Solve for y: 12y^2 = x - 5; y^2 = ------------

Question: What are the characteristics of a normal distribution? Instruction: Choose all options that best answer the question. Standard deviation will be high The smaller the sample, the more the normal distribution takes on a bell curve Samples are indicative of the population Most values are close to the mean value
Answer:
Samples are indicative of the population .
Most values are close to the mean value.
Step-by-step explanation:
The normal distribution is characterized by two parameters mean and standard deviation.
The graph of the normal distribution is symmetrical bell shaped curve called the normal curve. The location and shape of the normal curve are determined by mean and standard deviation.
We see from the figure as the mean and standard deviation increase the spread and curve change.
FALSE: Standard deviation will be high. This is false because more than 50% of the values lie 1 standard deviation of the mean .When the data is clustered around the mean the standard deviation is low.
FALSE: The smaller the sample, the more the normal distribution takes on a bell curve
The sample size greatly affects the normal curve. The greater the sample size the more likely the distribution is bell shape or normal curve.
TRUE: Samples are indicative of the population .
The normal distribution population with mean and standard deviation has a normal sample with and standard deviation.
Most values are close to the mean value
TRUE: About 68% of values are within 1 standard deviation of the mean and around 95% of values are within 2 standard deviations of the mean in the normal distribution.
Which means more than 50% of the values lie 1 standard deviation of the mean.
