Find the product of -2*(-4)*9. Describe how you use the properties of
multiplication to find the product. Is the product positive or negative?
Answer:
72
Step-by-step explanation:
-2 x -4 = 8
8 x 9 = 72
Hope this helps! Please mark Brainliest!
Answer:
72 = Positive
Step-by-step explanation:
The property we use,
→ Associative property
Now the product will be,
→ (-2 × -4) × 9
→ 8 × 9 = 72
→ -2 × (-4 × 9)
→ -2 × (-36) = 72
Then the required sign is,
→ Positive (+ve)
Hence, the product is 72.

1. conjugate -5+√x
2. conjugate 7-√b
-Please give an explanation!!
Answer:
1. [tex]-5-\sqrt{x}[/tex]
2. [tex]7+\sqrt{b}[/tex]
Step-by-step explanation:
The conjugate of a radical expression
[tex]a+\sqrt{b}[/tex]
is the expression
[tex]a-\sqrt{b}[/tex]
And vice-versa.
The conjugate is mostly used to rationalize radical expressions because the expression by its conjugate produces another expression without the radicals.
The question asks to find the conjugate of:
1. [tex]-5+\sqrt{x}[/tex]
The conjugate is
[tex]-5-\sqrt{x}[/tex]
2. [tex]7-\sqrt{b}[/tex]
The conjugate is
[tex]7+\sqrt{b}[/tex]

what is 0.0042 as a fraction in simplest form
Answer:
21/5000
Step-by-step explanation:
0.0042 takes the form of 21/5000 as a fraction.
Answer:
21/500
Step-by-step explanation:
0.0042 = 42/1000, (There is 4 digits to the right of the decimal point)
42 is an even number so, divide by 2 to simplify.
42/2 = 21 and 1000/2 = 500
21/500 is your final answer because 21 is divisible by 7 and 3 but 500 cannot be divided by either of those to get a whole number.
Hope this helps! :)

NEED HELP! A line has a slope of 9/7 and a y-intercept of 1/3. Which of the following is an equation of the line?
A 27x - 21y = -7
B 27x + 21y = 1
C 9x + 7y = 3
D 7x - 9y = -3
Please show work so I could understand this!
Answer:
A
Step-by-step explanation:
Take a look at the slope-intercept form of the equation .
[tex]y=mx+c[/tex]
Slope of 9/7 and y-intercept of 1/3 means replace m which is slope and c is the y-intercept which becomes
[tex]y=\frac{9}{7}x+\frac{1}{3}[/tex]
now we take LCM of 7 and 3 which becomes
[tex]y=\frac{27x+7}{21}[/tex]
and then,
[tex]21y=27x+7[/tex]
so A is our Answer
if arrange the equation accordingly
[tex]27x-21y=-7[/tex]

Which ordered pair is the solution to the system of linear equations Negative 5 x + y = 26 and 2 x minus 7 y = 16?
9514 1404 393
Answer:
(-6, -4)
Step-by-step explanation:
If you're going to use technology to answer your questions, you may as well use appropriate technology: a graphing calculator. It shows the solution to the system is the ordered pair (-6, -4).
__
The first of the given equations can be solved for y, then that used to substitute for y in the second equation.
y = 5x +26
2x -7(5x +26) = 16
2x -35x -182 = 16
-198 = 33x . . . . . . . . add 33x-16
-6 = x . . . . . . . . . . . . divide by 33
y = 5(-6) +26 = -4 . . . find y
The solution is (x, y) = (-6, -4).
3.128 Who Smokes More: Male Students or Female Students? Data 1.1 includes lots of information on a sample of 362 college students. The complete dataset is available at StudentSurvey. We see that 27 of the 193 males in the sample smoke, while 16 of the 169 females in the sample smoke. We will investigate the difference in proportions of male and female students who smoke.
Answer:
0.0452
Step-by-step explanation:
Given that:
There are a total of 193 males in the sample.
Number of males who smoke = 27
There are a total of 169 females in the sample.
Number of females who smoke = 16
The ratio of people who smoke to the total number of people is given by the formula:
[tex]\dfrac{\text{Number of people who smoke}}{\text{Total number of people in the sample}}[/tex]
So, the ratio of males who smoke is given as:
[tex]\dfrac{27}{193}=0.1399[/tex]
And
The ratio of females who smoke is given as:
[tex]\dfrac{16}{169} = 0.0947[/tex]
The difference between the ratio is = 0.1399 - 0.0947 = 0.0452

Statement A swimming pool contains 500 gallons of water. A hose is turned on, and it fills the pool at a rate of 24 gallons per minute. Which expression represents the amount of water in the pool, in gallons, after 8 minutes? A. 500 . 24 . 8 B. 500 + 24 + 8 C. 500 + 24 . 8 D. 500 . 248
Answer:
c. 500 + 24 * 8
Step-by-step explanation:
if there is 500 gallons of water already in the swimming pool and we are trying to add more and we are adding 24 gallons for 8 minutes to the already existing pool of water.
The expression 500 + 24 × 8 represents the amount of water in the pool, in gallons, after 8 minutes. The correct answer would be an option (C).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
If the swimming pool currently has 500 gallons of water in it and we are trying to add more, we would add 24 gallons of water over the course of 8 minutes.
As per the given information, the required expression would be as
500 + 24 × 8
Thus, the expression 500 + 24 × 8 represents the amount of water in the pool, in gallons, after 8 minutes.
Hence, the correct answer would be option (C).

I need help on this question
Answer:
a3
Step-by-step explanation:
suppose you are organizing a party and have a budget of b dollars for the appetizers. You plan to order v vegetarian spring rolls at $0.75 each and s shrimp rolls at $0.95 each.
The equation 0.75v+0.95s=b represents this constraint.
Solve 0.75v+0.95s=b for v
When would it be most helpful to use this equation?
Answer:
v = b/0.75 - 0.95s/0.75
Or
v = (b - 0.95s) / 0.75
Step-by-step explanation:
Solve 0.75v + 0.95s = b for v
This means making v the subject of the formula
0.75v + 0.95s = b
Subtract 0.95s from both sides
0.75v + 0.95s - 0.95s = b - 0.95s
0.75v = b - 0.95s
Divide both sides by 0.75
v = (b - 0.95s) / 0.75
v = b/0.75 - 0.95s/0.75
The equation will be useful in determining the number of vegetarian
