Perpendicular, parallel, or neither?
Answer:
The two lines are parallel
Step-by-step explanation:
Parallel lines have equal slopes and different y-interceptsThe product of the slopes of the perpendicular lines is -1 which means if the slope of one is m, then the slope of the other is [tex]-\frac{1}{m}[/tex] (reciprocal m and change its sign)The slope of the equation ax + by = c is m = [tex]\frac{-a}{b}[/tex]The slope of the equation by = ax + c is m = [tex]\frac{a}{b}[/tex]Let us use these rules to solve the question
∵ The 1st equation is -4y = -2x + b
∴ a = -2 and b = -4
∵ m = [tex]\frac{a}{b}[/tex] in this form of the equation
∴ m = [tex]\frac{-2}{-4}[/tex]
∴ m1 = [tex]\frac{1}{2}[/tex]
∵ The 2nd equation is 3x - 6y = 6
∴ a = 3 and b = -6
∵ m = [tex]\frac{-a}{b}[/tex] in this form of the equation
∴ m = [tex]\frac{-3}{-6}[/tex]
∴ m2 = [tex]\frac{1}{2}[/tex]
∵ m1 = m2
∴ The slopes of the two lines are equal
→ That means the two lines are parallel
∴ The two lines are parallel

A health club charges a one-time sign up fee of $99.99 plus a monthly charge of $12.75. A new member paid a total of $189.24 when she signed up. For how many months did she pay?
(A)7
(B)15
(C)22
(D)77
Answer: A. 7
Step-by-step explanation:
189.24 - 99.99 = 89.25
89.25 ÷ 12.75 = 7
Based on the information given the number of months did she pay is (A)7.
First step is to calculate the fee amount paid
Amount=$189.24 -$99.99
Amount=$89.25
Second step is to calculate for number of months
Number of months=$89.25 ÷ $12.75
Number of months= 7 months
Inconclusion the number of months did she pay is (A)7.

Complete question is;
Suppose we are testing the null hypothesis H0: μ = 20 and the alternative Ha: μ ≠ 20, for a normal population with σ = 5. A random sample of 25 observations are drawn from the population, and we find the sample mean of these observations is x¯ = 17.6. The P-value is closest to:
a. 0.0668.
b. 0.0082.
c. 0.0164.
d. 0.1336
Answer:
Option D
Step-by-step explanation:
We are given;
Null hypothesis; H0: μ = 20
Alternative hypothesis; Ha: μ ≠ 20
Population Standard deviation; σ = 5
Sample size; n = 25
Sample mean; x¯ = 17.6
Let's find the z-score from the formula;
z = (x¯ - μ)/(σ/√n)
z = (17.6 - 20)/(5/√5)
z = - 1.073
From online p-value from z-score calculator attached, using z = -1.073; two tailed hypothesis; significance value of 0.05,we have;
The P-Value is 0.283271.
Looking at the given options, the closest to the p-value is option D

Answer:
x = 20
Step-by-step explanation:
The triangle shown is an equilateral triangle. An equilateral triangle has angles that are all the same. Therefore, the expression 4x-20 equals the value of the angle, which is 60 degrees. To find x, you just have to do some simple algebra.
4x - 20 = 60 ..... set the expression equal to 60, that's what the angle equals
4x = 80 .... add 20 to both sides
x = 20 .... divide both sides by 4, and you get your answer

Which is greater 3.75 3.750
Answer:
None
Step-by-step explanation:
They are the same number
They are equal and neither is greater than the other.
In the decimal number system, trailing zeros after the decimal point do not affect the value of the number. They are considered insignificant and are not used to determine the magnitude or comparison of the numbers.
When comparing 3.75 and 3.750, it's important to understand that they represent the same value. The digits after the decimal point in both numbers are identical. The presence of the trailing zeros in 3.750 does not change the actual value of the number; it's just a different representation.
To illustrate this, let's consider the number line:
3.749 < 3.7499 < 3.74999 < 3.75 = 3.750 < 3.7501 < 3.75001 < 3.751
As you can see, both 3.75 and 3.750 lie at the same point on the number line, indicating that they are equal in value. The trailing zeros in 3.750 are insignificant and do not affect the magnitude or comparison of the numbers.
Therefore, in terms of their numerical value, 3.75 and 3.750 are equivalent and not different from each other.

The cost of the necklace before tax, for which Chris paid $9.18 including the sales tax of 8% is $8.5.
What is percentage increase ?Percentage increase is the amount added to the initial value in the percentage part.
Chris paid $9.18 for a necklace. This amount includes a sales tax of 8%.
Let the cost of the necklace before tax is x dollars. Now, the 108% of the x is $9.18. Thus,
[tex]x\times\dfrac{100+8}{100}=9.18\\x=\dfrac{9.18\times100}{108}\\x=8.5[/tex]

Answer:
a
Step-by-step explanation:
if you look at the equation, you can see there is an equal sign, so both costs must be the same. this marks out c and d.
each side of the equation has to be paired with one another. 16 and .55 have to be together, and 22 and .25 have to be together. in b, they are mixed up, so that makes it wrong.

Hello!
We can solve for the slope using the formula [tex]\frac{Rise}{Run}[/tex].
Rise is the change in y between two pointsRun is the change in x between two pointsWe need two points that belong on this line to find the slope. The two points I'm picking are (-1,-1) and (1,2).
