Answer:
The measure of angle L is 52
Step-by-step explanation:
Mathematically, in a triangle, the sum of the angles equal 180
So in this case;
J + K + L = 180
So therefore;
8x + 6 + 2x + 2 + 4x + 4 = 180
8x + 2x + 4x + 6 + 2 + 4 = 180
14x + 12 = 180
14x = 180 -12
14x = 168
x = 168/14
x = 12
So to get the measure of angel L, we simply substitute the value x in the equation for L
From the question, L = 4x + 4
So therefore L = 4(12) + 4 = 48 + 4 = 52

Find the x - and y-intercepts of the graph of the linear equation 2x + 3y = 12.
The x-intercept is
The y-intercept is
Answer:
Y intercept = (0,4)
X intercept = (6,0)
Step-by-step explanation:
First you need to make the equation slope intercept form.2x+3y=12
To do so, you need to get y on it's own (or on one side)
Subtract 3y from the left side.-3y+12=2x
Then, divide everything out by -3y-4=-2/3x
Add four to the other sidey= -2/3x +4
-2/3x= slope while 4= y intercept
You can also graph it on desmos and find the y intercept and x intercept
We want to find the x and y-intercepts of a given equation.
The solution is:
The x-intercept is x = 6 The y-intercept is y = 4First, we start by defining what x-intercept and y-intercept are.
The x-intercept is the x-value at which the graph of the equation intercepts the x-axis, and is equivalent for the y-intercept.
So, for a given function y = f(x).
We define the y-intercept as the value of y when we define x = 0.
And we define the x-intercept as the value (or values) of x when y = 0.
Here we have:
2x + 3y = 12
So to get the x-intercept, we just need to define y = 0 and solve for x.
2x + 3*0 = 12
2x = 12
x = 12/2 = 6
To get the y-intercept, we just need to define x = 0 and solve for y.
2*0 + 3*y = 12
3*y = 12
y = 12/3 = 4
Then we can conclude:
The x-intercept is x = 6 The y-intercept is y = 4If you want to learn more, you can read:

A researcher surveys job satisfaction among laborers and white-collar workers. (Job satisfaction is rated on a scale from 1 = low satisfaction to 10 = high satisfaction.) Results show that laborers have a mean job satisfaction score of 3 and a SD 1; white-collar workers have a mean job satisfaction rating of 7 and a SD of 3.16. Which statement is the best interpretation of the mean and SD?
A. Laborers are less satisfied than white collar workers and most laborers are about equally dissatisfied, while there is more variation in the satisfaction of white collar workers
B. Laborers generally are less satisfied than white-cofar workers, but laborers wojtas kely to be highly satisfied as white collar workers are to be highly satisfied
C. White-colar workers and laborers we bout equally waited but there is more variation among white collar workers
D. White collar workers are more satisfied than laborers, but have similar amount of variation
Answer:
Option A is the answer
Step-by-step explanation:
From the question we are told that
The mean of laborers is 3
The standard deviation is 1
The mean of white collar workers is 7
The standard deviation for white collar workers is 3.16
From this value given we can see that the white collar worker is more dissatisfied than the laborers
Also the from the value of standard deviation of the laborers we see that the deviation from the mean is 1 which means that they are equally dissatisfied
But in the case of white collar workers we see deviation from the mean is very high which implies that the dissatisfaction varies more with white collar workers
-10 - 6(2v – 8) = -82
Answer:
v = 10
Step-by-step explanation:
-10 - 6(2v-8) = -82
-10 - 12v + 48 = -82
-12v + 38 = -82
-12v = -120
v = 10
hope this helped, if you need a more in depth answer to how i did it just ask
Answer:
Hello! I hope I’m correct! :)
Step-by-step explanation:
The answer should be V = 10
First, Add 10 to both sides.
-6(2v-8) = -82+10
Next, Simplify
-6(2v-8) = -72
Than, divide both sides by -6
= -72/-6
{Note: two negatives makes a positive}
= 72/6
Simplify.
2v-8=12
Add (+) 8 to both of the sides.
2v= 12+8
Simplify 12+8 to...
2v = 20
Now, divide both sides by 2
V = 20/2
Since we have 20/2, we need to simplify (divide 20 & 2)
20 divided by 2 = 10
V = 10
Therefore the answer is v = 10Hope this helps! If you have any questions about these steps, feel free to ask! Have a nice day! :)

What’s 4.5 rounded to the nearest whole number
Answer: 5
Step-by-step explanation:
When the number after the point is 5 and above round up
4.5 rounded to the nearest whole number is 5.
When you round a decimal number to the nearest whole number, you are determining which whole number it is closest to.
For 4.5, you can visualize it on the number line.
The decimal number 4.5 lies exactly midway between 4 and 5.
To round to the nearest whole number, we look at the digit immediately to the right of the decimal point, which is 5.
Since 5 is greater than or equal to 5 (the midpoint), we round up to the next whole number, which is 5.
Therefore, 4.5 rounded to the nearest whole number is 5.

Ah, function problems, I had this in my math class around 2-3 weeks ago. So f and g is the function here.
TO SOLVE:
Simply look at where each plot is at. f(-3) is at (0, -3). So we will substitute -3 into f(-3).
Now, our equation should look like:
-6•(-3)-5•g(-7).
We can now take a look at the function, g. We can see that g(-7) lays at (-7, 6). We only need the Y here so it will be 6. Now, plug it in:

what does it mean to say that a number is a perfect square
Answer:
A perfect square is the product of a rational number multiplied by itself.
4, 9, and 16 are perfect squares
1, 2, 3, 5, 6, etc. are not perfect squares
Step-by-step explanation:
Answer:
please mark brainliest!
Step-by-step explanation:
NON-DETAILEDA number that is a perfect square is a number that can be square rooted kind of in a perfect match. Example would be 9 because it can be square rooted by 3 for 3 * 3. Another example that would not be a perfect square would be 30 because it can divided by 6 * 5 but neither one of those numbers are perfect squares.
DETAILEDA number called a perfect square means that the number has an exact squared root. In other words, the number has an squared power, which is exact.
Other way to see this, it's taking natural number 1, 2, 3, 4 then, applying the squared power to each one, the results of each squared power is what we call a perfect square. For example, 1, 4, 9, 16, 25, 36, are all perfect square, because they are the result of a squared power:
[tex]1^{2} = 1\\2^2 = 4\\3^2 = 9\\4^2 = 16\\5^2 = 25\\6^2 = 36[/tex]

Size (oz) Cost ($)
24
5.49
40
8.00
64
15.99
Answer:
The one that costs $15.99
Step-by-step explanation:
Divide 24/5.49=4 and something cents
Then 40/8 to get $5
Then 64/15.99 to get $4.00
The lowest price is $0.20 the size 40 oz bag cost $8.00 showing the lowest unit price.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
24 oz bag cost $5.49
Cost of 1 oz cat food = 5.49/24 = $0.228
40 oz bag cost $8.00
Cost of 1 oz cat food = 8/40 = $0.2
64 oz bag cost $15.99
Cost of 1 oz cat food = 15.99/64 = 0.2498
Thus, the lowest price is $0.20 the size 40 oz bag cost $8.00 shows the lowest unit price.

Nita finds that the expression (a + 1) 2 is sometimes, but
not always, greater in value than (a + 1) 3 when she evaluates both expressions
for the same value of a. How do you explain this finding?
I guess the expressions are supposed to be (a + 1)² and (a + 1)³.
Consider the inequality,
(a + 1)² > (a + 1)³
Move everything to one side:
(a + 1)² - (a + 1)³ > 0
Factorize the left side:
(a + 1)² (1 - (a + 1)) > 0
-a (a + 1)² > 0
a (a + 1)² < 0
Notice that the left side is exactly 0 if either a = 0 or a = -1.
Now consider the following 3 cases:
• If a < -1, then a is negative, while (a + 1)² is always non-negative, which means a (a + 1)² will always be negative.
• If -1 < a < 0, then again a is negative, so a (a + 1)² is also negative.
• If a > 0, then a (a + 1)² is always positive.
So the inequality is satisfied for all a in the interval (-∞, -1) ∪ (-1, 0). This is to say that (a + 1)² is always greater than (a + 1)³ if a is chosen from this domain.
Another way to look at this: assume a + 1 falls between -1 and 1. Whenever you scale a number between -1 and 1 by another number in the same range, the product will always be smaller than the original number.
More concretely, let's say a + 1 = 1/2. So for instance, 1/2 * 1/2 = (1/2)² = 1/4, and 1/4 is clearly smaller than 1/2. If we multipy again by 1/2, we get 1/2 * 1/2 * 1/2 = (1/2)³ = 1/8, which is smaller than 1/4.
