A)
4y = x
y = 1/4 x
k = 1/4 Yes
B)
y = 4x
k = 4 No
C)
32y = 8x
y = 8/32 x
y = 1/4 x
k = 1/4 Yes
D)
y = 0.25x
k = 0.25 = 1/4 Yes
E)
1/4 y = 2x
y = 4 * 2x
y = 8x
k = 8 No

write an equation for a line with slope of 1/4 passing through -1,-5 in slope intercept form
Answer:
y = 1/4x - 19/4
Step-by-step explanation:
Use the equation y = mx +b
x (x coordinate) = -1
y (y coordinate) = -5
slope (m) = 1/4
Plug in!
-5 = 1/4(-1) + b
-5 = -1/4 + b
-5 + 1/4 = b (Add 1/4 to both sides)
-20/4 + 1/4 = b
-19/4 = b
y = 1/4x - 19/4

Answer:
x = 10
Step-by-step explanation:
Angles 12x and 10x + 20 are "vertical angles," meaning that they are identical (same value). Therefore we can write the equation 12x = 10x + 20, which reduces to 2x = 20, or x = 10.
Answer:
x=10
Step-by-step explanation:
Hey There!
Those are a pair of vertical angles
Therefore they are congruent
congruent meaning identical in form
So we would setup and equation and because the angles are congruent the equation would be
12x=10x+20 and solve for x
Step 1 subtract 10x from each side
10x-10x cancels out
12x-10x=2x
now we have
2x=20
Step 2 divide each side by 2
2/2 cancels out
20/2=10
Therefore x=10

What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The area of a triangle is given by the formula:
A = (1/2)bh
where A is the area, b is the base length, and h is the height.
We are given that the area of the triangle is 2/5 square meters and the height is 3/5 meters.
Plugging these values into the formula, we get:
2/5 = (1/2)bh
b = (2/5) / [(1/2)(3/5)]
b = (2/5) / (3/10)
b = (2/5) * (10/3)
b = 4/3

A private plane traveled from Seattle to a rugged wilderness, at an average speed of 132 mph. On the return trip, the average speed was 110 mph. If the total traveling time was 6 hours, how far is Seattle from the wilderness?
Answer:
Brainliest PLEASE!
Step-by-step explanation:
a = seattle
b = wilderness
t = time traveling at 132 mph
(4-t) = time traveling at 110 mph
distance traveled at 132 mph = 132(t)
distance traveled at 110 mph = 110(4-t)
but the two distances are equal so:
132t = 110(4-t), solving for t
t = 1.82 hrs
d= 1.82 hrs * 132 m/hr = 240 miles

What is the slope of a line perpendicular to the line who’s equation is x-y=5 fully reduce your answer
Answer:
-1
Step-by-step explanation:
Use the slope intercept formula(y=mx+b) to find the slope of a line.
First, you will want to put everything into it's proper order, so you will get -y=-x+5.
You cannot have a negative y, so divide everything by -1 and you will get y=x-5.
1 is the slope. Now that you know that, you will want to find the reciprocal. To find the reciprocal, you will need to swap the numerator and the denominator and then swap it's sign, whether that is positive or negative..
The reciprocal of 1 is -1. -1 is the slope of the perpendicular line

Suppose that you want to save money and would like to find a savings option that earns you the most
money in interest. You have $1000 to put towards savings. After surveying several banks for savings
plans, you found these options. "A" represents the amount you will have in the bank after x years.
Option A: Your money would receive simple interest at the end of 5 years.
The formula is: A = 1000 + 1000(0.05)x
Option B: Your money will be compounded continuously.
The formula is: A = 1000(2.71828)(0.05x)
Option C: You will invest in a CD (Certificate of Deposit) compounded yearly.
o The formula is: A = 1000(1.05)*
Option D: You buy a US Savings Bond.
The savings bond costs $1000 now. When cashed in 5 years later, the amount will be
$1267. You must leave the money in the savings bond for 5 years to earn any interest.
But, you do not receive any additional interest if you leave it in longer than 5 years.

solve for x. im pretty confused on how to do this i thought it was 60 but i was wrong
Answer: x = 12
Step-by-step explanation:
You're on the right track! You're right in saying that each angle has to be 60 degrees since they're supposed to add up to 180. However, the question is asking what x equals, so we set up the equation:
5x = 60
x = 12
12 students have blue eyes. if there are 25 students in the class, what percent of students have blue eyes
Answer:
3
Step-by-step explanation:
First, you need to turn 12 into 0.12. Then, you multiply that by 25 and boom you get 3.
This is the same every time.
For example, what percent is 28 of 49?
0.28*49=13.72.
Out of 25 students 48% students have blue eyes.
What is percentage?Percentage is the relative value indicating one hundredth part of any quantity.Percentage is denoted by (%).How to find what percent of students have blue eyes?According to the question,
Total number of students in the class = 25Total number of students having blue eyes = 12Now, we can calculate the percentage by the formula, [tex](\frac{number}{total})[/tex] x 100 %
∴ percentage of students have blue eyes [tex](\frac{12}{25})[/tex] x 100 % = 48 %
∴ percentage of students have blue eyes are 48 %

1. 4 dimes
2. 1 nickel and 3 pennies
3. 5 quarters and 1 dime
Answer:
1) 40%
2) 8%
3) 160%
Step-by-step explanation:
1) a dime is 10 cents. 10+10+10+10 = 40
.40/1.00 = 0.4 move the decimal to places to the right to turn into a percentage. 40%
2) 1 nickel is 0.05 cents and 3 pennies equal 0.03 cents. 0.05+0.03= 0.08 0.08/1.00=0.08
move the decimal to places to the right to turn into a percentage. = 8%
3) a quarter is 0.25 cents and a dime is 0.10 cents.
6 quarters = 0.25+0.25+0.25+0.25+0.25+0.25= 1.50
1.50 + 0.10= 1.60
1.60/1.00= 1.60 move the decimal to places to the right to turn into a percentage 160%

Answer: x=4
For this equation, you are solving for x. So first you want to get the 1/2x on a side by its self to make it easier to solve. So to do that subtract both sides by 3. (2=1/2x) Once you do that multiply both sides by 2 to get rid of the 1/2 so x is on one side by itself. (4=x) And that's your answer!

Students in a statistics class are conducting a survey to estimate the mean number of units students at their college are enrolled in. The students collect a random sample of 45 students. The mean of the sample is 12.1 units. The sample has a standard deviation of 1.5 units. What is the 95% confidence interval for the average number of units that students in their college are enrolled in
The 95% confidence interval for the average number of units that students in their college are enrolled in is approximately 11.66 to 12.54 units. This means that we are 95% confident that the true population mean lies within this interval.
Here,
To calculate the 95% confidence interval for the average number of units that students in their college are enrolled in, we can use the formula for a confidence interval for a population mean when the population standard deviation is unknown but can be estimated using the sample standard deviation.
The formula for the confidence interval is given by:
Confidence Interval = Sample Mean ± (Critical Value) * (Standard Error)
where:
Sample Mean (x) is the mean of the sample (12.1 units in this case).
Critical Value is the value from the t-distribution corresponding to the desired confidence level and the sample size.
For a 95% confidence level and a sample size of 45, the critical value is approximately 2.013 (you can look this up in a t-table or use a calculator).
Standard Error is the standard deviation of the sample mean, which is calculated as the sample standard deviation divided by the square root of the sample size.
Given the information in the problem:
Sample Mean (x) = 12.1 units
Sample Standard Deviation (s) = 1.5 units
Sample Size (n) = 45
Confidence Level = 95%
Critical Value ≈ 2.013
Now, let's calculate the standard error:
Standard Error = s / √n
Standard Error = 1.5 / √45 ≈ 0.2236
Now, calculate the confidence interval:
Lower bound of the confidence interval:
12.1 - (2.013 * 0.2236) ≈ 11.66
Upper bound of the confidence interval:
12.1 + (2.013 * 0.2236) ≈ 12.54
So, the 95% confidence interval for the average number of units that students in their college are enrolled in is approximately 11.66 to 12.54 units. This means that we are 95% confident that the true population mean lies within this interval.

To start factoring 2x2 - 5x - 3, we need to find two numbers whose sum (p + q) equals -5 and whose
product (p.q) equals
What value belongs in the blank?
Answer:
-6
Step-by-step explanation:
First we need to factorize the given expression
2x^2 - 5x - 3,
2x^2 - 6x+x - 3
The two number that we are going to use to split -5x are -6 and 1
Hence the required two numbers are -6 and 1
Let p = -6
Let q = 1
Taking their sump+q = -6 + 1 = -5
Take the product
p*q = -6 * 1
p*q = -6
hence the product is equal to -6
