The graph of g(x) is the graph of f(X) = x + 6 reflected across the x-axis. Which equation describes g?
g(x)= - x + 6
g(x)= - 6x - 6
g(x)= -x - 6
g(x)= x - 6
The reflection of a function across the x-axis changes the sign of the function. In this case, g(x) = -x - 6 is the correct equation representing the reflected graph.
Explanation:The correct equation that describes the graph g(x) reflected across the x-axis from f(x) = x + 6 is g(x) = -x - 6. When reflecting a function across the x-axis, the sign of the function changes in the equation. Therefore, g(x) would be obtained by changing the sign for the x-term in f(x).

Blueberries are on sale for $2.80 per pint. The regular price is $3.50 per pint.
What is the percent of decrease?
Select from the drop-down menu to correctly complete the statement.
Answer: The percent of decrease= 20 %.
Step-by-step explanation:
Regular price of blueberries= $3.50per pint
Current selling price=$2.80 per pint
Clearly, there is decrease in price as 'Current selling price' < 'Regular price'
Now, Decrease in price=Regular price-Current selling price
[tex]=\$3.50-\$2.80=\$0.70[/tex]
We know that Decrease percentage =[tex]\frac{\text{Decreased price}}{\text{Regular price}}\times100[/tex]
[tex]=\frac{0.70}{3.50}\times100\\=\frac{7}{35}\times100\\=\frac{1}{5}\times100\\=20\%[/tex]
Therefore, the percent of decrease= 20 %.
The question is Model 24% on a 5x5 grid.
The attachment to the grids are below.
Answer:
Option 2 is correct .
Step-by-step explanation:
Given : A big cube 5*5 which contains small 25 cubes
Solution :
Let 25 small cubes denotes 100%
So , 1% is denoted by : [tex]\frac{25}{100}[/tex]
So, 24 % is denoted by :
⇒[tex]\frac{25*24}{100}[/tex]
⇒[tex]6[/tex]
Thus to show 24% on 5*5 , 6 small cubes must be shaded .
In Option 2 , 6 small cubes are shaded.
Hence , Option 2 is correct .

Three more than twice the sum of a number and half the number equals 105. Which equation models this relationship?
when you find less than 100% of a number how does your answer relate to the original number.... answers are the a) the numbers are equal b) it is less than the original number c) it is greater than the original number d) there is no relationship
b) it is less than the original number. Finding less than 100% of a number means the answer is b) less than the original number, since 100% represents the whole.
Explanation:When you find less than 100% of a number, the answer is b) it is less than the original number. This is because 100% of a number represents the number itself, so any percentage less than 100% means you're taking a part of the number which is smaller than the whole. For example, finding 50% of a number is the same as finding half of it - clearly, half of something is less than the whole.
Fiona eats 75 grams of trail mix. How many calories does she eat? If 50 trail mix= 150
Final answer:
To find out how many calories are in 75 grams of trail mix when 50 grams contain 150 calories, set up a proportion and solve for x. The calculation shows that 75 grams of trail mix contains 225 calories.
Explanation:
If 50 grams of trail mix contains 150 calories, to find out how many calories are in 75 grams of trail mix, we need to set up a proportion since the relationship between the weight of the trail mix and the calories it contains is a direct one. This means that if the weight goes up, the calories will also go up by the same rate.
To calculate the calories in 75 grams of trail mix, we use the following steps:
Understand the given information: 50 grams = 150 calories.Set up a proportion to find out how many calories are in 75 grams:mitt ate 24 peanuts this represents 75% of the bag of peanuts how many peanuts were originally in the bag
A 14-ounce box of cereal sells for $2.10. What is the unit rate?
Answer:
The unit rate is equal to [tex]0.15\frac{\$}{ounce}[/tex]
Step-by-step explanation:
we know that
The unit rate is the ratio of two measurements in which the second term is equal to one
In this problem to find the unit rate, divide the total cost of cereal by the total weight of cereal
so
[tex]\frac{2.10}{14}\frac{\$}{ounces} =0.15\frac{\$}{ounce}[/tex]
therefore
The unit rate is equal to [tex]0.15\frac{\$}{ounce}[/tex]

what is the reciprocal of 1/9
The reciprocal of a number is the number gotten when you flip or invert the fraction. Hence, the reciprocal of 1/9 is 9.
Explanation:The reciprocal of a number is calculated by flipping, or 'inverting', the fraction. It's essentially interchanging the numerator and denominator. In the case of 1/9, the reciprocal would be 9/1.
To clarify, the reciprocal of 1/9 is 9/1, which simplifies to 9. So, the reciprocal of 1/9 is 9.
The reciprocal of a fraction is obtained by taking the reciprocal of the numerator and denominator. To find the reciprocal of 1/9, we simply invert the fraction. Inverting means swapping the numerator and denominator. So the reciprocal of 1/9 is 9/1 or simply 9.
