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

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.
f(x)=x2+8x+6. What is the value of f(4)?

g The test statistic of z=2.27 is obtained when testing the claim that p≠0.826. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of α=0.01, should we reject H0 or should we fail to reject H0?
Answer: a. Hypothesis test is two tailed as [tex]H_a[/tex] is two tailed.
b. p-value =p-value
c. We failed to reject [tex]H_0[/tex].
Step-by-step explanation:
Given : Test statistic : z = 2.27
Claim: p ≠ 0.826 i.e. Alternative hypothesis : [tex]H_a:p\neq0.826[/tex] [ alternative hypothesis takes ≠]
a. Hypothesis test is two tailed as [tex]H_a[/tex] is two tailed.
b. The two-tailed p-value for z=2.27 is 0.0232. [By p-value table]
c. Using a significance level of α=0.01,
p value > α
so we failed to reject [tex]H_0[/tex]. [When p-value > α we cannot reject null hypothesis.]
Write any number and its additive inverse.
Answer: Additive Inverse of 17 = -17
The two addends in an addition equation are interchangeable, which means that the answer to "What is the additive inverse of -17?" or "What is the additive inverse of negative 17?" is 17. Since the additive inverse of 17 is -17, additive inverse is also known as the opposite number.

alexis made 24 cookies with 8 teaspoons of sugar and 45 cookies with 15 teaspoons of sugar. what is the constant of proportionality?
Answer:
3:1
Step-by-step explanation:
divide the cookies by the number of spoons
24 cookies per 8 spoons = 3 cookies per 1 spoon
45 cookies per 15 spoons = 3 cookies per 1 spoon
all the above results both had a proportionality of 3 cookies to 1 spoon arriving to the result 3:1On 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.
7x-5=8(x+3) solve for x
Answer:
The value of x is -29.
Step-by-step explanation:
We are given an algebraic equation and have one goal: solve for x. We can use simplifying techniques as well as addition and subtraction to solve this equation.
[tex]\text{7x - 5 = 8(x + 3) \ \ \ Distribute the 8 throughout the parentheses.}\\\text{7x - 5 = 8x + 24 \ \ \ \ Subtract 7x from both sides.}\\\text{-5 = x + 24 \ \ \ \ \ \ \ \ \ \ Flip the equation.}\\\text{x + 24 = -5 \ \ \ \ \ \ \ \ \ \ Subtract 24 from both sides.}\\\small\boxed{\bold{{x = -29}}}[/tex]
Now that we have solved for x, we can plug in -29 to see if we get a true statement.
[tex]\text{7(-29) - 5 = 8(-29 + 3)}\\\text{-203 - 5 = -232 + 24}\\\text{-208 = -208} \ \checkmark[/tex]
Because we ended up with a true statement, we have determined that the value of x is -29.
Answer:
[tex]7x - 5 = 8(x + 3) \\ 7x - 5 = 8x + 24 \\ 8x - 7x = - 24 - 5 \\ \boxed{x = - 29}[/tex]
x = -29 is the right answer.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.

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.

find the measures of -5x+32
Answer: What shape is this? A triangle?
Step-by-step explanation:
Assuming that this is a triangle with no 90 degree angles:
-5x + 32 = 180
-32 = -32
---------------------
-5x = 148
----- = -----
-5 = -5
x = -29.6
Assuming that this is a triangle with 90 degree angles:
-5x + 32 = 90
-32 = -32
----------------------
-5x = 58
----- = -----
-5 = -5
x = 11.6

Bill runs around the perimeter of a circular track at 11 ft/sec. The track has a radius of 110 yd. After 24 seconds, Bill turns and runs to the center of the track along a straight (radial) line. Upon reaching the center, he turns and runs away along a different radial line to his starting position on the perimeter. Assume Lee does not slow down when he makes these two turns.
Required:
a. Sketch a picture of the situation.
b. How far has Lee traveled once he returns to his starting position?
c, How much time will elapse during Lee's circuit?
d. Find the area of the pie shaped sector esclosed by Lee's path.
Answer:
Step-by-step explanation:
We can see the sketch of the diagram in the image attached below.
Since 1 yard =3 feet
110 yards = 330 feet
Using: Distance = speed * time
If the speed of Lee is 11 ft/sec, he will travel the distance = 11 ft/sec * 24 sec = 264 ft in 24 sec.
The distance traveled = 264 ft
After traveling 264 ft, he takes a turn radially towards the center, then again takes a turn as he reaches the center.
b)
Total Distance traveled = A + B + C
A = C = 330 ( radius of the circle)
= 330 + 110 + 330
= 770 ft
c) Using the expression:
Speed = Distance/time
time = Distance/Speed
time = 770/11
time = 70 sec
d)
Area = 1/2 r²θ
Area = 1/2 r² (l/r)
Area = 1/2 × r × l
Area = 1/2 × 330 × 110
Area = 18150 ft²

A vacuum cleaner has a wholesale price of $50. and a markup rate is 50%. What is the markup and retail price of the vacuum?
Answer:
Retail price = $75
Step-by-step explanation:
1. State the given
The price of the vacuum cleaner's wholesale; $50.
The rate of mark up that the vacuum cleaner is sold at; 50%.
This means that the vacuum cleaner's sales price is 1.5 times the price of its wholesale.
2. Form am equation and solve
Use the equation:
wholesale_price * markup = retail_price
Now use the given information
50 * 1.5 = retail price
Solve
50 * 1.5 = 75
retail price = $75
Carolyn was asked to solve the following system of equations. Her work is shown. What is the solution to the system of linear equations?
Answer:
(11, 13)
Step-by-step explanation:
Carolyn's work is incorrect. Below is the correct solution:
Given:
[tex] 3x - 2y = 7 [/tex] ----› Equation 1
[tex] y = x + 2 [/tex] -----› Equation 2
Substitute y = (x + 2) in equation 1
[tex] 3x - 2y = 7 [/tex] ----› Equation 1
[tex] 3x - 2(x + 2) = 7 [/tex] (substitution)
[tex] 3x - 2(x) -2(+2) = 7 [/tex] (distributive property)
[Note: this is where Carolyn made a mistake]
[tex] 3x - 2x - 4 = 7 [/tex]
Collect like terms
[tex] x - 4 = 7 [/tex]
[tex] x = 7 + 4 [/tex] (addition property of equality).
[tex] x = 11 [/tex]
Substitute x = 11 in equation 2
[tex] y = x + 2 [/tex] -----› Equation 2
[tex] y = 11 + 2 [/tex] (substitution)
[tex] y = 13 [/tex]
✅The solution to the system of equations would be:
