The table shows a linear function. Which equation represents the function?
Question is not complete and so I have attached the complete question.
Answer:
C: f(x) = -½x + 4
Step-by-step explanation:
Using slope formula between 2 points, we know that;
slope; m = (y2 - y1)/(x2 - x1)
Let's consider 2 points from the table;
(0, 4) and (-4, 6)
Thus;
m = (6 - 4)/(-4 - 0)
m = 2/-4
m = -½
Now using slope intercept form equation which is y - y1 = m(x - x1), we can find the equation of the function by picking on point say (0, 4).
Thus;
y - 4 = -½(x - 0)
y - 4 = -½x
y = -½x + 4
Thus;
f(x) = -½x + 4
What is the solution to the system of equations
Answer:
(0,3)
Step-by-step explanation:
solve for 2y
-X-2y= -6
2y=6+2x
substitute the given value of 2y into the equation -x-2y=-6
-x-(6+3x)= -6
solve for x
x=0
substitute the given value of X into the equation 2y=6+3x
2y=6+3×0
solve for y
y=3
the solution is (0,3)

Một ủy ban an toàn kiểm tra ngẫu nhiên 900 công nhân xây dựng trong thời gian làm việc, thấy có 48 công nhân không mang mũ bảo hộ. Hãy ước lượng tỷ lệ công nhân không mang mai bảo hộ trong thời gian làm việc với độ tin cậy 98%
Answer:
The percentage of workers not wearing the helmets is 5.3 %.
Step-by-step explanation:
A safety committee randomly examined 900 construction workers during their work, and found that 48 workers were not wearing helmets. Estimate the percentage of workers who do not wear protective masks during their working time with 98% confidence
total workers = 900
Not wearing helmet = 48
Percentage which are not wearing the helmets
= [tex]\frac{48}{900}\times 100 = 5.3 %[/tex]%

Solve by finding the square roots: 3x2 - 9 = 3
Answer:
x= 2 or x= -2
Step-by-step explanation:
3x² -9= 3
+9 on both sides:
3x²= 9 +3
Simplify:
3x²= 12
Divide by 3 on both sides:
x² =4
Square root both sides:

Select ALL the correct answers. Which of the given functions have an average rate of change of -12 on the interval [0, 2]?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the functions are not given.
The general explanation on calculating average rate of change is as follows.
The average rate of change (m) of function f(x) over interval (a,b) is:
[tex]m = \frac{f(b) - f(a)}{b-a}[/tex]
Take for instance:
[tex]f(x) = x^2 + 4x + 4[/tex]
[tex](a,b) = (0,2)[/tex]
The average rate of change over [tex](0,2)[/tex] is:
[tex]m = \frac{f(2) - f(0)}{2-0}[/tex]
[tex]m = \frac{f(2) - f(0)}{2}[/tex]
Calculate f(2) and f(0)
[tex]f(2) = 2^2 + 4*2 + 4 =16[/tex]
[tex]f(0) = 0^2 + 4*0 + 4 =4[/tex]
So, we have:
[tex]m = \frac{f(2) - f(0)}{2}[/tex]
[tex]m = \frac{16 - 4}{2}[/tex]
[tex]m = \frac{12}{2}[/tex]
[tex]m = 8[/tex]

(6x-4) (3x+4)º find the value of x.
Answer:
x = 20
Step-by-step explanation:
The angles form a straight line so they add to 180 degrees
6x-4 + 3x+4 = 180
Combine like terms
9x=180
Divide by 9
9x/9 = 180/9
x= 20

Each bag of rocks for an aquarium costs $12.35. Which equation best represents y, the total cost of x bags of rocks?
Answer:
The equation is
y = $ 12.35 x
Step-by-step explanation:
Cost of one bag of rocks = $ 12.35
Let there are x bags of rocks, so that the total cost is y.
So, the cost of 1 bag = $ 12.35
cost of x bags = $12.35 x
The total cost is
y = $12.35 x
It is the equation of a straight line which passes from origin and the slope is 12.35.
What is the last answer and how is it wrong?
Answer and Step-by-step explanation:
I think it wants you to keep it in the form it showed. I remember doing this this year, so it should be:
[tex]\frac{f(a+h)-f(a)}{h} = \frac{3a +3h + 6 -(3a + 6) }{h}[/tex]
Then after this step you distribute the negative, and combine like terms. After, you divide the h and you get 3 as your answer.
IF it still doesn't work like how I showed it, contact your teacher for help, saying you are pretty sure you got it right (if you put mine and it didn't work) but it is saying it is incorrect.

what is 4b + 6 ≤ 18. I don't know how to solve it and don't know the answer.
Answer:
b≤3
Step-by-step explanation:
For this problem, you want to solve it similarly to linear equations.
We start with 4b+6≤18.
Subtracting 6 from both sides gives 4b≤12.
From there, in order to isolate the b, we must divide both sides by 4, leaving b≤3.

4 and one-third divided by 5 and StartFraction 1 over 6 EndFraction The reciprocal of a fraction must be found to solve the problem. What is the reciprocal fraction that is required?
Answer:
multiply by the reciprocal of 31/6
Step-by-step explanation:
4 and one-third = 4 1/3
5 and StartFraction 1 over 6 EndFraction = 5 1/6
Therefore,
4 1/3 ÷ 5 1/6
= 13/3 ÷ 31/6
To solve the problem, multiply 13/3 by the reciprocal of 31/6
The reciprocal of 31/6 = 6/31
So,
13/3 ÷ 31/6
= 13/3 × 6/31
= (13 * 6) / (3 * 31)
= 78 / 93
= 26/31

[ Easy Math ] Help me pls
Answer:
1) you're going to have to flip the coins (or fake numbers) for the experimental trials.
2) for the theoretical, there is 1/2 chance for heads or tails with each toss, so you'd expect that out of 10 tosses, 5 heads, 5 tails. out of 100 tosses- 50 heads, 50 tails.
When tossing 2 coins- 1/2×1/2 = 1/4 (25%) chance that 2 heads, 2 tails, or 1 heads & 1 tails. Deviation value comes from after you done your flipping and recorded your data. So if on 100 flips you actually got 50 and 50 (rarely us that exact ;), the deviation from the expected of 50/50 would be 0.00. If however you flipped 100 heads or 100 tails (impossible), then the deviation value would be 1.00.
|(100-50)| ÷ 50 = 50÷50 = 1.00
So usually you may have data like: 47/53 or something a little off than 50/50, making deviation |(47-50)| ÷ 50 = 3÷50 = 0.06.
Now the number of flips is important for the outcome! So if a coin toss if 10 times had 4 heads, 6 tails, the deviation value would be:
|(4-5)| ÷ 5 = 1÷5 = 0.20
So increasing the # flips DECREASES the deviation value!!
Whether it's from 10 to 100, or from 100 to 200. Look at my example of how the 10-flip deviation of 0.20 decreased to 0.06 with 100-flip
