Answer:
-3 and 3
Step-by-step explanation:
Absolute value makes a negative number positive and allows a positive number to stay the same. |-3| becomes 3, and |3| stays as 3, so the correct answers are -3 and 3.
Write the equation of the line in fully simplified slope-intercept form.
You see from the graph that when x = 0, y = 2 so the y-intercept is ( 0 , 2).
you are given points (-6 , 3) and (6 , 1). Find slope:
slope = change in y / change in x
slope = (3 - 1) / (-6 - 6)
slope = 2/-12
slope = -1/6
slope-intercept form: y = mx + b where m = slope and b = y intercept.
y = -1/6x + 2

Hopes this helps please mark brainliest
Answer:
Answer = 88 ft²
Step-by-step explanation:
Step 1: Divide the composite shape into two separate parrellagrams
1. Dimensions of shape 1: Length is 10 ft, and width is 4 ft
2. Dimensions of shape 2: Length is 8 ft, and width is 6 ft
Step 2: Multiply the length by the height of each shape
Area = lw
3. Area of shape 1: 10 ft ∙ 4 ft = 40 ft²
4. Area of shape 2: 8 ft ∙ 6 ft = 48 ft²
Step 3: Add both areas together to get the total area of the composite shape
5. 40 ft² + 48 ft² = 88 ft²
Hence, the total area of this composite figure is 88 ft²

Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of puppies = 7
Number of adult dogs = 4
This can be written as,
7 puppies = 4 adult dogs
Multiply 6 on both sides.
42 puppies = 24 adult dogs

Tim lives 2/3 as far from school as Felipe. Felipe walks to school and then walks to
Tim's house after school. What expression represents the total distance
Felipe walked?
Answer: x + 2/3(x)

What is an arithmetic sequence?It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8, 10 is an arithmetic sequence.
We have,
In the first month, the author sold 2500 books, but the sales were declining steadily at 12% each month.
This means,
a = 2500
12% of 2500
12/100 x 2500
= 12 x 25
= 300
d = 300
Now,
The sum of an arithmetic sequence is given as,
S(n) = a + d(n - 1)
Now,
n = 18
a = 2500
d = 300
S(23):
= 2500 + 300(18 - 1)
= 2500 + 300 x 17
= 2500 + 5100
= 7600
Thus,
The total number of books sold over the first 18 months is 7600.

12 less than twice a number.
help me please help help
Answer:
2x - 12
Hope this helps : )
Step-by-step explanation:
The equation for 12 less than twice a number is 2x-12. This is because "12 less than a number" means 12 is being subtracted from a number. The "number" is a variable which can be x. "Twice a number" is the variable being multiplied by 2. So the final equation would be 2x - 12.
the following are the amount of time, in minutes, that it took a random sample of 20 technicians to perform a certain task: 18.1 20.3 18.3 15.6 22.5 16.8 17.6 16.9 18.2 17.0 19.3 16.5 19.5 18.6 20.0 18.8 19.1 17.5 18.5 18.0 assuming that the sample came from a symmetric continuous distribution, use the sign test at the 0.05 level of significance to test the null hypothesis that the mean of the population is 19.4 against a 2-sided alternative. perform the test using: (a) the binomial distribution; (b) the normal approximation to the binomial distribution.
The normal approximation to the binomial distribution is C ( n , r ) * p^r * q^n - r .
a )
the binomial distribution .
Null hypothesis H0: μ = 19.4
Alternative hypotheses H1: μ ≠ 19.4
19.4 with minus sign, we get
n = 20, x = 4 and n/2 = 10
Here x < n/2
Therefore, from table the computed P-Value is.
b )
the normal approximation to the binomial distribution ,
P = 2P(X ≤ 4 when θ = 1/2 )
= 2 (0.0059)

An investor invested a total of $2000 in two mutual funds. One fund earned a 9%
profit while the other earned a 2% profit. If the investor's total profit was $89,
how much was invested in each mutual fund?
$340 was invested in the 9% fund and 1660 was invested in the 2% profit fund.
Step-by-step explanation:
Let x be amount invested in 9% profit fund
let (2000-x) be the amount invested in the 2% profit fund
.09x+.02 times (2000-x)=89
.09x+40-.02x=89
0.07x=49
x=340
The amount invested in mutual fund A and mutual fund B is $700 and $1300 respectively.
what is profit margin?Profit margin is a measure of profitability. It is calculated by finding the profit as a percentage of the revenue. It is given by :
profit margin = (profit / revenue or return) × 100
Given here $ 2000 invested in two mutual funds
let the amount invested in A be x then the amount invested in B is $2000-x
now profit in dollars from the two mutual funds is equal to $89
therefore, 9% of x + 2% of $2000-x = $89
0.09x + 0.02×(2000-x) = 89
0.09x + 40 - 0.02x = 89
0.07x = 49
x = $700
Hence the amount invested in A is $700 and amount invested in B is $1300.

A car drives down a road in such a way that its velocity (in m/s) at time t (seconds) is v(t)=2t1/2+1. Find the car's average velocity (in m/s) between t=4 and t=8
Average velocity of the car as calculated from the given data is 6m/s.
The average velocity is calculated by dividing the total distance travelled by the whole time that has passed. Given the velocity as a function of time, you may integrate the velocity function from t = 4 to t = 8 to determine the total distance travelled.
The opposite of taking a derivative is to integrate; in other words, the function I get when I take a derivative is 2t1/2 + 1. Assuming you are aware of how to do that If not, you can input the aforementioned integral into your TI-84 to obtain the result.
The integral turns out to be
(4/3)t^3/2 + 4t so x(t)
= (4/3)t3/2 + 4t and x(8) - x(4)
= (4/3)(8)3/2 + 4(8) - [(4/3)(4)3/2 + 4(4)]
= 24 meters
The distance travelled in total was 24 meter and it took 4 seconds (8-4) to do it, so the average velocity is 24 /4 = 6 m/s.

The attached graph is defined by f(x) = x² + 5|x| + 6.
What is the graph function?
The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x). So, the graph of a function is a special case of the graph of an equation.
We have,
y = x² + 5|x| + 6
we know,
|x|² = x² use this ,
y = |x|² + 5|x| + 6
Steps for drawing y = |x|² + 5|x| + 6
step1 :- first draw y = x² + 5x + 6, this graph is quadratic equation .
step2:- Leave the part of y=x² + 5x + 6 right side to the y-axis and also take its image with respect to the y-axis as a plane mirror.
step3 :- now remove the part of y = x² + 5x + 6 to left side from y - axis .
now your graph is ready
you can see in the figure attached.
Hence, the attached graph is defined by f(x) = x² + 5|x| + 6.

What is midpoint of line segment ?A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line. The midpoint is the point on the middle of the line that is equally distant from the two points if a line is drawn connecting the two points. The midpoint is the point B that lies halfway between any two points, let's say A and C. As a result, measuring the length of the line segment and dividing it by two will yield the midway.
According to the given information :
AE = 18, DE = 5
However, D is the middle of CE
CE = 2 × 5 = 10
