Find the zero of the function f(x)= 4x+8
Answer:
x = -2
Step-by-step explanation:
Solve for x:
4 x + 8 = 0
Subtract 8 from both sides:
4 x + (8 - 8) = -8
8 - 8 = 0:
4 x = -8
Divide both sides of 4 x = -8 by 4:
(4 x)/4 = (-8)/4
4/4 = 1:
x = (-8)/4

The graph of the parent function f(x) = x3 is transformed such that g(x) = f(-2x³). How does the graph of g(x) compare
to the graph of f(x)?
The transformation from the parent function are (a) g(x) is horizontally stretch by 1/2 and reflected across the y-axis
How to describe the transformation from the parent function?From the question, we have the following function that can be used in our computation:
f(x) = x³
g(x) = (-2x)³
First, we have the transformation to be:
From f(x) = x³ to f'(x) = (−x)³
This means the function is reflected across the y-axis
So, we have the following representation
f'(x) = f(-x)
Next, we have:
From f'(x) = (−x)³ to g(x) = (−2x)³
This means the function is horizontally stretched by a factor of 1/2
Hence, the transformation is reflection across the y-axis and horizontally stretch by 1/2

One angle measures 130°, and another angle measures (8k + 58)°. If the angles are vertical angles, determine the value of k.
Vertical angles are pairs of angles that are located on opposite sides of a line and are equal in measure, the value of k is 9.
How to find value of k ?Vertical angles are pairs of angles that are located on opposite sides of a line and are equal in measure. They are formed when two lines intersect, and they are always congruent, or equal in measure.
That if one angle measures 130°, the measure of its vertical angle must also be 130°.
If the other angle has a measure of (8k + 58)°, and it is a vertical angle to the angle that measures 130°, then it must also have a measure of 130°.
We can set up the equation 130 = 8k + 58 and solve for k to find the value of k.
Subtracting 58 from both sides gives us 72 = 8k. Dividing both sides by 8 gives us k = 9.
Therefore, the value of k is 9.

Mike sells grapes at a farmers market. Each pound of grapes sells for the same amount. The table below shows the total prices for different numbers of pounds of grapes sold.
Grapes
Number of Pounds Sold Total Price ($)
2 $4.50
4 $9.00
10 $22.50
A. Write an equation that describes the relationship between the number of pounds of grapes sold(x) and the total price (y), in dollars.
Mike also sells red peppers at the farmers market. The equation below can be used to find the total price (p) in dollars of r pounds of red peppers.
p = 1.80r
B. What is the total price, in dollars, of 17 pounds of red peppers? Explain what the 1.80 represents in the context of the situation.
The farmer decides to increase the price per pound of the grapes. A graph is created to represent both the original equation from Part A and a new equation based on the increased price per pound of the grapes.
C. Thinking about what this graph would look like, explain why the graphs representing the equations will share one point even though the prices per pound are different.
A. The relationship between the number of pounds of grapes sold (x) and the total price (y) can be described by the equation y = 2.25x.
The required details for pounds in given paragraph
This equation can be derived from the data in the table by substituting the values for x and y and solving for the coefficient 2.25. For example, for x = 2 pounds of grapes, we have y = $4.50, so 4.50 = 2.25 * 2. Similarly, for x = 4 pounds of grapes, we have y = $9.00, so 9.00 = 2.25 * 4. We can use this equation to find the total price for any number of pounds of grapes sold.
B. The total price of 17 pounds of red peppers is $31.60. The 1.80 in the equation p = 1.80r represents the price per pound of red peppers. In this case, 1.80 dollars is the price per pound of red peppers, and r is the number of pounds of red peppers that are being purchased. Therefore, the total price of r pounds of red peppers is equal to 1.80 dollars per pound multiplied by the number of pounds of red peppers being purchased.
C. The graphs representing the equations for the original and increased price per pound of grapes will share one point because the two equations will be tangent to each other at that point.

A 30" stainless steel smooth-top electric range is on
sale for $479.99, a savings of 20% off the regular price. Find the
regular price.
$600 is the regular price of the stainless steel
How to determine the regular price?Percentage simply means the number or ratio that can be expressed as a fraction of 100. In this case, when we have to calculate percent of a number, we then divide the number by the whole and multiply by 100.
Given: Sales price with discount = $479.99, savings = 20% off. This implies there is a 20% discount.
Let P represent the regular price. Thus, we can write:
P - (20% of P) = $479.99
P - 0.2P = 479.99
0.8P = 479.99
P = 479.99 / 0.8
P = $599.9875 ≈ $600
Thus, the regular price of the stainless steel is $600

A fair spinner has 9 equal sections: 4 red, 3
blue and 2 green.
It is spun twice.
What is the probability of getting the same
colour twice?
the probability to get two consecutive reds will be 19.75%.
What is probability?
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.
A fair spinner has 9 equal sections: 4 red, 3 blue and 2 green.
The probability of not getting two consecutive red is 1 minus the probability of getting two consecutive greens. Since the spinner is fair, the probability of getting a green on any one spin is 4/9
Since consecutive spins are independent, the probability of getting two consecutive red is (4/9)² = 16/81= 19.75%
Hence the probability to get two consecutive reds will be 19.75%.

The given probability is based on conditions of two events, hence it is called as conditional probability and it's formula according to the events is option.a [tex]p(\frac{C}{A})=\frac{p(\frac{A}{C}).p(C)}{p(A)}[/tex]
Bayes' rule is a mathematical theorem that allows you to modify probability statements in response to new information. With this rule, you can reverse the conditional probability statement and find the probability of the first event occurring given the probability of the second event occurring by using the probability of the second event occurring given the probability of the first event occurring.The first event in this case is that the bolt is defective (event C). The second occurrence is that it was selected from the first machine (event A). As a result, given that the bolt is from the first machine, we can state the conditional probability that it is defective.
Hence, the formula is [tex]p(\frac{C}{A})=\frac{p(\frac{A}{C}).p(C)}{p(A)}[/tex].

Which ordered pair makes both inequalities true? y > -2x + 3 and y < x - 2
(0, 0) (0, -1) (1, 1) (3, 0)
Answer:
Step-by-step explanation:
The answer is (3,0)
You need to plug in the values of x and y to figure it out, because a coordinate is in the form (x,y) so in (3,0) 3 is the x value and 0 is the y value.
If you plug (3,0) into the first inequality y > -2x+3 you get 0 > -3 which is true
steps
-2(3) +3 = -3
And if you plug (3,0) into the second inequality y < x-2 you get 0 < 1 which is also true
So basically just plug in the values of x and y into the inequality and test if it works on one of the inequalities you've been given if it doesn't try the next order pair, if it does try it on the other inequality and check if it works on it to.
