Find the equation of the line through (-4,-1) and parallel to y = -1/2x +1 in slope-
intercept form.
d) y = -1/2x - 3
c) y = 1/2x + 3
b) y = 2x - 3
a) y = -1/2x + 3
Step-by-step explanation:
Let the equation of the line be y = mx + c
since the line is parallel to y = -1/2x + 1, the two lines have the same gradient.
therefore, m = -1/2
sub (-4, -1):
-1 = -1/2(-4) + c
c = -3
therefore equation of the line is y = -1/2x - 3
This question demands knowledge on coordinate geometry's slope intercept form and finding unknowns. If you would like to venture further, you can check out my Instagram page (learntionary). Thanks!

Calculate the producers' surplus (in dollars) for the supply equation at the indicated unit price
p.
(Round your answer to the nearest cent.)
p = 7 + 2q1⁄3; p = 20
Answer:
Step-by-step explanation:
Given the equation of the unit price expressed as;
p = 7 + 2q1⁄3, we are to find the value of q when p = 20
20 = 7 + 2q1⁄3
20-7 = 2q/3
13 = 2q/3
Cross multiply
13 * 3 = 2q
39 = 2q
q = 39/2
q = $19.5
Hence the producer surplus is 1950 cents

Which statement about the graph is true?
On a coordinate plane, a line goes through points (0, 2), (2, 3), (4, 4), (6, 5).
A. The graph shows a proportional relationship because it is a line, and the difference between each point is the same.
B. The graph shows a proportional relationship because it is a line, and each x-value is a multiple of 2.
C. The graph does not show a proportional relationship because each point written as a ratio gives a different value.
D. The graph does not show a proportional relationship because a line that increases by 1 in the y-value cannot have a constant of proportionality.
Answer:
a
Step-by-step explanation:
Answer:
C. The graph does not show a proportional relationship because each point written as a ratio gives a different value.
Step-by-step explanation:
The equation of a line in slope-intercept form is
y = mx + b
Where m is the slope and b is the y-intercept.
Not all lines represent proportional relationships. The condition for a line to be a proportional function is that b=0, i.e., the y-intercept is the origin.
The graph shown in the figure has a y-intercept of 2, thus the line is not a proportional relationship.
If the equation of the line is proportional (b=0), then:
y = mx
Or:
y/x = m
The ratio between each value of y and x must be constant.
This is not the case, because
3/2, 4/4, 6/5 result in different values and 2/0 doesn't even exist. Thus the correct answer is:
C. The graph does not show a proportional relationship because each point written as a ratio gives a different value.

Line segment JL is an altitude in triangle JKM. Triangle K J M is shown. Angle K J M is a right angle. An altitude is drawn from point J to point L on side K M to form a right angle. The length of K J is 13, the length of J L is 5, and the length of J M is 8. Which statement explains whether JKM is a right triangle? Round measures to the nearest tenth. JKM is a right triangle because KM = 15.3. JKM is a right triangle because KM = 18.2. JKM is not a right triangle because KM ≠ 15.3. JKM is not a right triangle because KM ≠ 18.2.

A wooden artifact from an ancient tomb contains 20 percent of the carbon-14 that is present in living trees. How long ago, to the nearest year, was the artifact made?
Answer:
The artifact was made approximately 13,306 years ago
Step-by-step explanation:
The half-life of Carbon-14 = 5730 years
The formula for radioactive decay is given by the equation:
[tex]N=N_0 e^{- \lambda t}\\where:\\N = Number\ of\ particles\ at\ time\ t\\N_0= Number\ of\ particles\ at\ time\ t_0\\\lambda = decay\ constant = \frac{In}{t_{1/2}} ; t_{1/2} = half-life\\t = time\ in\ years[/tex]
The amount of Carbon-14 left = 20% = 20/100 = 0.2
[tex]\therefore \frac{N}{N_0} = 20 \% = 0.2[/tex]
[tex]N=N_0 e^{- \lambda t}\\\\dividing\ both\ sides\ by\ N_0\\\frac{N}{N_0} = e^{- \lambda t}\\0.2 = e^{- \lambda t}\\taking\ natural\ logarithm\ of\ both\ sides\\In 0.2 = Ine^{- \lambda t}\\In0.2 = -\lambda \times t\\but\ \lambda = \frac{In2}{t_{1/2}} \\\therefore In0.2 = -\lambda \times t\\\\= In0.2 = - \frac{In2}{t_{1/2}} \times t\\where\ t_{1/2} = 5730\ years\\-1.6094 = - \frac{0.6931}{5730} \times t\\-1.6094 = - 0.00012095 \times t\\t = \frac{-1.6094}{-0.00012095} \\t = 13,306.32[/tex]
t ≈ 13,306 years

System of linear equations:
X+ Y= 2000
10x + 20y = 35000
Can someone explain in words how they would solve this?
Answer:
x= 500 y= 1500
Step-by-step explanation:
Isolate x or y in the first equation
Isolating for x would be x= -y+2000
Substitute X=-y+2000 into equation 10x+20y=35000
10(-y+2000)+20y=35000
Exapnd the equation above and you should get y=1500
Same steps for finding x by isloating for y
the circumference of a circle is about 53.38 cm. The radius of the circle is 8.5 cm. Which expression best represents the value of pi?
Answer:
Step-by-step explanation:
Circumference of a circle is expressed as;
C = 2πr
r is the radius of the circle
Given
C = 53.38cm
radius r = 8.5cm
Substitute into the formula to get π
From the formula;
π = C/2r
π = 53.38/2(8.5)
π = 53.38/17
π = 3.14cm
The value of pi is 3.14 cm
Answer:
It's C

Answer:
[tex] x = 17.5 [/tex]
Step-by-step explanation:
Since the two triangles are similar, their corresponding side lengths would be proportional. Therefore:
[tex] \frac{28}{16} = \frac{x}{10} [/tex]
Cross multiply
[tex] x*16 = 10*28 [/tex]
[tex] 16x = 280 [/tex]
Divide both sides by 16
[tex] x = \frac{280}{16} [/tex]
[tex] x = 17.5 [/tex]
Show work. This is a BC calculus problem.
Answer:
D.
Step-by-step explanation:
Recall that the limit definition of a derivative at a point is:
[tex]\displaystyle{\frac{d}{dx}[f(a)]= f'(a) = \lim_{x \to a}\frac{f(x)-f(a)}{x-a}}[/tex]
Hence, if we let f be ln(x + 1) and a be 1, this yields:
[tex]\displaystyle f'(1)= \lim_{x \to 1}\frac{\ln(x+1)-\ln(2)}{x-1}}[/tex]
Hence, the limit is equivalent to the derivative of f at x = 1 or f’(1).
In conclusion, our answer is D.

On Wednesday, a farmer picked 1 16/31 baskets of peppers. On Thursday, the farmer picked 2 10/21 baskets. On Friday, the farmer picked 1 5/19 baskets. Approximately each quantity to the nearest 1/4, how many baskets of peppers did the farmer pick?
Answer:
5.25
Step-by-step explanation:
Given that,
On Wednesday, a farmer picked 1 16/31 baskets of peppers. On Thursday, the farmer picked 2 10/21 baskets. On Friday, the farmer picked 1 5/19 baskets.
To find,
How many baskets of peppers did the farmer pick.
Solution,
It can be calculated by adding all the baskets of peppers on Wednesday, Thursday and Friday as follows :
[tex]P=1\dfrac{16}{31}+2\dfrac{10}{21}+1\dfrac{5}{19}\\\\=\dfrac{47}{31}+\dfrac{52}{21}+\dfrac{24}{19}\\\\=5.25[/tex]
So, he will pick 5.25 baskets of peppers.
