Which statement correctly describes the function on a given interval?
A. The function is decreasing and nonlinear between x= -7 and x= -3
B. The function is increasing and nonlinear between x= -3 and x= -1
C. The function is decreasing and linear between x= -1 and x= 1
D. The function is increasing and linear between x= 1 and x= 3
Answer:B !!!
Step-by-step explanation:
Option D is correct, the function is increasing and linear between x= 1 and x= 3.
What is a function?A relation is a function if it has only One y-value for each x-value.
By observing the graph we say that the function is increasing and linear between x= 1 and x= 3
For a function y = f(x), if the value of y increases on increasing the value of x, then the function is an increasing function.
Linear functions are those whose graph is a straight line
Hence, option D is correct, the function is increasing and linear between x= 1 and x= 3.

Sammy tried to verify the solution by substituting x = 5 back into the original equation. It did not result in a true statement. Which explains why Henry’s solution is incorrect?
Step 1 is wrong because the distributive property of equality was used incorrectly.
Step 2 is wrong because the addition property of equality was used incorrectly.
Step 3 is wrong because the subtraction property of equality was used incorrectly.
Step 4 is wrong because the division property was used incorrectly.
Answer:
Step 3 is incorrect
Step-by-step explanation:
4(-1/2x + 7) + 5x = 15
-2x + 28 + 5x = 15
3x + 28 = 15
3x + 28 - 28 = 15 - 28
3x = -13
5. That cool CD you have been waiting to purchase has finally gone on sale over at Wal-Mart for 25% off the original price. You borrow your room-mates employee discount card and head on over to your local Wal-Mart. It turns out the employee discount entitles you to an additional 15% off the sale price of the CD. If the original price was $32.99, what was the total final price you paid for your cool new CD including the 7.5% sales tax
Answer: $22.61
Step-by-step explanation: A 25% discount means that instead of paying the full value, you will pay 25% less. So the total price you will pay for a CD of $32.99:
P₁ = 32.99 * (1 - 0.25)
P₁ = 32.99 * (0.75)
P₁ = 24.7425
However, you still have a discount of 15% over the price, so:
P₂ = 24.7425 * (1 - 0.15)
P₂ = 24.7425 * (0.85)
P₂ = 21.03
The sales tax is a value incorporated over the price after all the discounts:
P = 21.03 * (1 + 0.075)
P = 21.03 * (1.075)
P = 22.61
The total final price for the CD is $22.61.

¾+(⅓÷⅙)-(-½)=( ) need help with this question
Answer:
3.25 or 3 1/4
Step-by-step explanation:
Remove the parentheses first: 3/4 + (1/3 / 1/6) - (-1/2)
1/3 / 1/6 turns into 1/3 * 6
Reduce the numbers:
3/4 + (1/3 * 6) + 1/2
cross multiplication, 6 divided by 3 = 2.
So the new equation is 3/4 + 2 + 1/2
Then you calculate.
3/4 + 2 + 1/2 = 13/4
13/4 reduced is 3 1/4 or 3.25

ASA congruence criterion = when two angles of two triangles are equal and their included side is also equal, we can consider those triangles to be congruent to each other.
Since two angles in triangle △ABC and△CDA are equal and since their included side is also equal we can conclude that they are congruent.
Therefore, △ABC ≅ △CDA under the ASA congruence criterion.

Suppose that E and F are points on the number line.
If EF = 12 and E lies at -9, where could F be located?
Answer:
either at -21 or 3
Step-by-step explanation:
we know that the length is a total of 12 so it either goes 12 spaces to the left or to the right of -9
-9 - 12 is -21 and -9 + 12 is 3
Type of triangle the has side measures of 6cm, 7cm and 12cm. And one angle with a measure of 120 degrees
Answer:
Obtuse triangle
Step-by-step explanation:
Given
Sides: 6cm, 7cm and 12cm
Angle: 120 degree
Required
Determine the type of triangle
Because the measure of an angle of the triangle was mentioned, we have to classify the triangle by its angle.
From the question, we understand that one of the angles is greater than 90 (i.e. 120 degrees). This type of triangle are referred to as obtuse triangles.

The area of a parallelogram can be found by finding the product of its height and base. The area of the resulting figure is 105/4 sq. ft.
What is a Parallelogram?A parallelogram can be defined as a quadrilateral which has equal and parallel opposite sides. The sum of the adjacent angles of a parallelogram is equal to 180° and its opposite angles are equal.
Each side of the square is given 4 1/2 ft,
And the height of each parallelogram 1 1/2 ft.
Now, the area of square is (side)^2 and the area of parallelogram is height × base.
Thus, area of given figure is given as,
Area = (4 1/2)^2 + 2×(4 1/2)×( 1 1/2)
= 105/4 sq. ft.
Hence, the area of the given figure is 105/4 sq. ft.

Peyton and her children went into a restaurant and where they sell drinks for $3 each
and tacos for $4 each. Peyton has $40 to spend and must buy at least 10 drinks and
tacos altogether. If Peyton decided to buy 4 drinks, determine all possible values for
the number of tacos that she could buy. Your answer should be a comma separated
list of values. If there are no possible solutions, submit an empty answer.
Answer:
7,6
Step-by-step explanation:
So in total Peyton must buy 10 items. Since she's already buying 4 drinks. We need to find the amount of tacos the max amount of tacos she can buy are 7 tacos and the minimum is 6 because if we bought less than 6 it wouldn't have met the criteria for 10 items minimum. And if we passed 7 tacos it would go past the limit of how much money Peyton has. I hope this helped:)

Answer:
1). x = 81
2). x = 84
Step-by-step explanation:
1). By applying geometric mean theorem in the given triangle,
[tex]\frac{x}{18\sqrt{14}}= \frac{18\sqrt{14}}{56}[/tex]
56x = (18√14)²
56x = 4536
x = [tex]\frac{4536}{56}[/tex]
x = 81
2). By applying geometric mean theorem,
[tex]\frac{x}{8\sqrt{21}}= \frac{8\sqrt{21} }{16}[/tex]
16x = (8√21)²
16x = 1344
x = [tex]\frac{1344}{16}[/tex]
x = 84
A skin-care company had 1,500 people try a new acne cream. Nine people had a mild allergic reaction. The formula is then improved and those 1,500 people try the new cream. Only 4 of them had a mild allergic reaction. What is the percent decrease in number of allergic reactions?
Answer:
The decrease in number of allergic reactions is of 0.3333%.
Step-by-step explanation:
Initial percentage:
Nine out of 1500, so the percentage is:
[tex]\frac{9*100}{1500} = \frac{900}{1500} = 0.6[/tex]
Initially: 0.6% of allergic reactions.
Final percentage:
Four out of 1500, so the percentage is:
[tex]\frac{4*100}{1500} = \frac{400}{1500} = 0.2667[/tex]
WIth the improved formula: 0.2667% of allergic reactions.
What is the percent decrease in number of allergic reactions?
0.6% - 0.2667% = 0.3333%
The decrease in number of allergic reactions is of 0.3333%.
A publisher reports that 52% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 180 found that 46% of the readers owned a laptop. Find the value of the test statistic. Round your answer to two decimal places.
Answer:
The value of the test statistic is [tex]t = -1.61[/tex]
Step-by-step explanation:
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
Our test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the expected mean, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
A publisher reports that 52% of their readers own a laptop.
This means that [tex]\mu = 0.52[/tex]
Sample of 180:
Means that [tex]n = 180[/tex]
By the Central Limit Theorem:
[tex]\frac{\sigma}{\sqrt{n}} = s = \sqrt{\frac{0.52*0.48}{180}} = 0.0372[/tex]
A random sample of 180 found that 46% of the readers owned a laptop.
This means that [tex]X = 0.46[/tex]
Find the value of the test statistic.
[tex]t = \frac{X - \mu}{s}[/tex]
[tex]t = \frac{0.46 - 0.52}{0.0372}[/tex]
[tex]t = -1.61[/tex]
The value of the test statistic is [tex]t = -1.61[/tex]
