1/(x^4) or x^-4
Answer:
[tex]\frac{1}{x^{4}}[/tex]; x ≠ 0
Or if thats wrong, just put 1/x^4
Step-by-step explanation:
Okay so heres how we solve this
Rewrite:
The "x is a non zero" is a very poorly written exception so I completely understand if you started racking your brain over that
[tex]x^{-10}*x^6[/tex] ; x ≠ 0
Note; you can ignore the expression until you write the simplified answer.
1 - Multiply using rules of exponents
[tex]x^{-10} * x^6 = x^{(-10~+~6)} = x^{-4}[/tex]
2 - Get rid of the negative exponent by using rules of exponents
[tex]x^{-4} = \frac{1}{x^4}[/tex]
3 - Rewrite with it being simplified
1/(x^4); x ≠ 0
An EPA contractor needs to test the concentration of a substance in ten samples of the ground water. Seventy samples were
already collected from a single source over the course of a week at regular intervals. The contractor wants to test samples
evenly over the course of that time frame.
Answer:
Systematic sampling
Step-by-step explanation:
An EPA contractor needing to test the concentration of a substance in ten samples out seventy samples provided form a single source at regular time intervals.
For the contractor to effectively carry out the testing he has to employ a Non-probability system of sampling which is called Systematic sampling, because in systematic sampling we can assume the population size (x ) which in this case is 70 and the sample size( n ) to be 10
He will have to select ; ( x / n )^th of the sampling frame for best results

Answer:
your doing slope too?
Step-by-step explanation:
bro im doing that rn
Answer:
Slope: 1
Y intercept: 2 or (0,2)
Equation: y=x-2
Step-by-step explanation:
Can you find the slope-intercept of the line? Thank you!
Answer:
y = x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 2) ← 2 points on the line
m = [tex]\frac{2-0}{0+2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
The line crosses the y- axis at (0, 2) ⇒ c = 2
y = x + 2 ← equation of line
Annie wants to make several plates of apples and apricots, so that each plate has the same number of apples and the same number of apricots. At most, how many plates can she make, if she is going to use 8 apples and 20 apricots.
At most, 8 apples and apricots can be arranged at ___ plates, so that each plate contains ___ and ___ apricots.
Please help! I need help filling in the blanks.
Answer:
At most, 8 apples and apricots can be arranged at 4 plates, so that each plate contains 2 apples and 5 apricots.
Step-by-step explanation:
they are asking for the GREATEST amount of plates, but there are less apples than apricots so we must find the GCF, which is 4. then you divide the amount of apples by 4 as well as the amount of apricots by 4.

these 2 questions ASAP!! BRAINLIEST & 30 points!!
Answer:
1.) 2/5
2.) -7/5
Step-by-step explanation:
Slope Formula: m = y2 - y1/x2 - x1
1.) 2/5
m = y2 - y1/x2 - x1
m = -1 - (-3)/0 - (-5)
m = -1 + 3/0 + 5
m = 2/5
2.) -7/5
(-2,3) and (3,-4)
m = y2 - y1/x2 - x1
m = -4 - 3/3 - (-2)
m = -4 - 3/3 + 2
m = -7/5
There were 400 sweets in a pack. The principal of a school bought 25 such packs of sweets for 2000 children o Children's Day. If each child was given 7 sweets, how many more packs of sweets were needed?
Answer:
10 more packs
Step-by-step explanation:
400 sweets bought 25 such packs = 400*25=10000
2000 each one gets 7 = 2000*7=14000
14000-10000=4000
4000/400 is 10.
So 10 more packs.
Hit the crown :D
Answer:
Step-by-step explanation:
400 sweets in a pack * 25 packs = 10,000 sweets
2000 kids * 7 sweets = 14,000
We need 4,000 more sweets. That would be 10 packs more since there are 400 sweets in a pack.
"Twelve less than two-thirds a number is 48"What is the number?
Answer:
-54
Step-by-step explanation:
1.) 12-2/3x=48
2.) Multiple by 3 on both sides
36-2x=144
3.) Move the constant on the other side by subtracting it.
-2x=144-36
4.) Subtract numbers
-2x=108
5.) Divide both sides by -2
-2=108
÷2 ÷2

Hi again I need a story that matches the equation -6 + 3x = 2 + 4x
Answer:
A.
Step-by-step explanation:
The required stories that are models of the given expression -6 + 3x = 2 + 4x are given in A and B. Both options are correct.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Option A,
At 5 p.m., the temperatures recorded at two weather stations in Antarctica are -6 degrees and 2 degrees. The temperature changes at the same constant rate, x degrees per hour, throughout the night at both locations. The temperature at the first station 3 hours after this recording is the same as the temperature at the second station 4 hours after this recording.
So from the above statement,
The equation modeled is given as
-6 + 3x = 2 + 4x
The above expression is equivalent to the given statement. So story mentioned in option A matches the given equation.
Similarly,
The equation formed in Option B also matches the given equation.
Thus, both options are correct.

What are the slope and the y-intercept of the linear function that is represented by the table?
Step-by-step explanation:
I refuse to answer lol
Find the center and radius of the equation of the circle
a). x2 + y2 – 8x +6y + 9 = 0
Compare the given equation with the general equation of a circle
Given equation: x² + y² - 8x +6y +9 = 0
Equation of a circle: x² + y² + 2gx + 2fy + c = 0
2g= -8; g = -8÷2= -4
2f = 6; f = 6÷2 = 3
c= 9
Solving for radius of the circle...
r =√g² + f² - c
g= -4, g² = ±16
f = 3, f² = 9
Substituting, we have
r = √16 + 9 - 9
r = √25-9
r=√16
r = 4
Therefore, the centre and radius of the circle is 9 and 4 respectively.

If Marie were to paint her living room alone, it would take 3 hours. Her sister Patricia could do the job in 6 hours. How many hours would it take them working together? Express your answer as a fraction reduced to lowest terms, if needed.
Answer: 2
Step-by-step explanation:
the rate Marie paints the room= 1/3
The rate her sister paints the room= 1/6
working together their combined rate is 1/3+1/6 =9/18
the time for then to work together= 9/18
= 2 hours.

I would assume that the angle of f equals 50°... sincesince the triangles are similar that means that the angles are most likely equal to each other. since the big triangle you can do it 90 + 40 which equals 130 then 180, since that is the total degrees in a triangle, minus 130 equals 50 this means 50 ° is the angle of c. keep in mind angle c equals angle f.

y varies inversely as X. y=4 when x=2. Find y when x=16
Answer:
y = 32 (Verified Answer) ✅Step-by-step explanation:
We will use a proportion to solve this.
[tex]\frac{2}{4} = \frac{16}{y}[/tex]
Now, we cross multiply.
2y = 16 x 4
2y = 64
Now, we must divide by 2 to get the correct value for y
y = 64/2
y = 32
Now, we can use the same proportion to check our answer.
2(32) = 16 x 4
64 = 64 ✅

Answer:
y = 1/2
Step-by-step explanation:
The inverse relation means ...
y = k/x
We can find k from ...
xy = k = (2)(4) = 8
Then when x = 16, we have ...
y = 8/x = 8/16 = 1/2
y is 1/2 when x = 16.
What is the product of StartFraction 4 Over 9 EndFraction and StartFraction 1 Over 11 EndFraction? StartFraction 4 Over 99 EndFraction StartFraction 5 Over 99 EndFraction StartFraction 9 Over 44 EndFraction One-fourth
Answer:
4/24
Step-by-step explanation:
Because 1/6 is 4/24 simplified.
To prove this, all you have to do is try simplifying 4/24 yourself. To do that, we are going to use 4 to divide both the numerator and the denominator because 4 is a common factor of 4 and 24.
(To simplify a fraction, you divide both the numerator and denominator by a common factor)
So 4 divided by 4 is 1, and 24 divided by 4 is 6

If pqrs is a parallelogram, find the measure of
113
5.67
18
67
Answer:
∠PSR = 113°
Step-by-step explanation:
Two angles in a parallelogram that are next to each other are supplementary. That means that they add up to 180°, so 7x-13+4x-5 = 180. Solve for x.
7x-13+4x-5=180
11x-18=180
11x=198
x=18
Now plug x back into the angle that opposite from the one you are looking for (they are equal)
7(18)-13 = ∠PSR
126-13 = ∠PSR
113 = ∠PSR
