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.
"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
6,) Then you get x=-54
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

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
What is the equation of the line that passes through the point (-3, 4) and has a slope of 1/3?
Answer:
y = 1/3x + 5
Step-by-step explanation:
y - y1 = m(x - x1)
y - (4) = 1/3(x - (-3)
y - 4 = 1/3(x + 3)
y - 4 = 1/3x + 1
y = 1/3x + 1 + 4
y = 1/3x +5

To answer the question, we need to know what polynomials are
What are polynomials?Polynomials are algebraic expressions that contains variables and coefficients.
a.
2 - x² + 4x + x² = 2 - x² + x² + 4x
= 2 - 0 + 4x
= 2 + 4x
Since it has two terms, it is a binomial
b.
x - 5x² + 3 - 2 = x - 5x² + 1
= - 5x² + x + 1
Since it has three terms, it is a trinomial
c.
x² - x² + x² - x² + 3 = 0 + 0 + 3
= 3.
Since this contains a single term, it is a monomial
d.
7x - x² + x³ + 4x² = x³ + 4x² - x² + 7x
= x³ + 3x² + 7x
Since it has three terms, it is a trinomial
e.
-6x - x² + 6x - 4x = -6x - x² + 2x
= - x² + 2x - 6x
= - x² - 4x

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.
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

how do i do this?
Answer: [tex]6x^2y^3[/tex]
Explanation:
The numbers 2 and 3 multiply to 6, so that's why the final coefficient is 6.
The x terms multiply to [tex]x*x = x^2[/tex]
The y terms multiply to [tex]y*y*y = y^3[/tex]
The exponent tells us how many copies of the base to multiply.
So overall, [tex]2*x*x*3*y*y*y = 6x^2y^3[/tex]

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

Answer:
k = 2.5
Step-by-step explanation:
So we start off with: 2.5(4k+2) = 12k
Let's first distribute.
10k + 5 = 12k
Now let's subtract 10k from both sides.
5 = 2k
Now let's divide both sides by 2.
2.5 = k

Step-by-step explanation:
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
