Write an equation for the line that is parallel to the given line that passes through the given point.
y = -6x + 2; (-1,2)
Answer:
The correct answer is y = -6x - 4
Step-by-step explanation:
The given equation of the line : y = -6x + 2
Now, the general equation of the line in the slope-intercept form is given by : y = mx + c
Now, comparing the given equation with the general form, We get slope, m = -6
We need to find the equation of the line which is parallel to the given line and since the slope of two parallel lines are equal so the slope of the required line will also be -6
And it passes through the point (-1, 2)
The required equation will be :
⇒ y - 2 = -6 × (x + 1)
⇒ y - 2 = -6x - 6
⇒ y = -6x - 4
Therefore, The required equation is y = -6x -4
Hence, The correct answer is. y = -6x - 4

The cash value of the computer system in 3 years will be $1632. The correct option is the third option $1632
DepreciationFrom the question, we are to determine the cash value of the computer system in 3 years
From the given information,
The computer system cost $2,395 and it will depreciate at a rate of 12% a year
After the first year, the worth of the computer system will be
$2,395 - (12% of $2,395)
$2,395 - (0.12 × $2,395)
= $2,395 - $287.4
= $2107.6
After the second year, the worth of the computer system will be
$2107.6 - (12% of $2107.6)
$2107.6 - (0.12 × $2107.6)
= $2107.6 - $252.912

Step-by-step explanation:
Given two points:

To find:
The slope
Solution:
We know that,
[tex] \rm Slope(m) = \cfrac{ y_2 - y_1}{x_2 - x_1} [/tex]
According to the question,
y_2 = 0y_1 = 14x_2 = -2x_1 = 16Note:[The underscore refers to that the numbers after the underscore is a subscript]
So Substitute them on the formulae:
[tex] \implies \rm \: m = \cfrac{0 - 14}{ - 2 - 16} [/tex]
Simplify it.
[tex] \implies \rm \: m = \cfrac{ \cancel{- 14} \: {}^{7} }{ \cancel{- 18} \: {}^{9} } [/tex]

Thus,the slope is 7/9 in fraction and 0.80 (Nearest tenth) in decimal.
A computer randomly picks a number from the group 20, 21, 22, 23, 24, 25, 26, 27. What is the probability the number is greater than 24 or less than 21?
Answer:
The answer you're looking for is .5
Step-by-step explanation:
Cause 20 is less than 21, and 25, 26, and 27 is larger than 24, and that's 4 numbers. There's 8 numbers in total, so your answer is 4/8. Divide that by 4, and you get 1/2. That's 50%, if you're thinking out of "1" then it would be ".5"
Answer: 0.5 or 50%
Numbers-Set {20, 21, 22, 23, 24, 25, 26, 27}
Total outcomes: 8
numbers greater than 24 are 25, 26, 27 - 3 numbers
number less than 21 is 20 - 1 number
Total favorable outcomes: 3 + 1 = 4
Probability = favorable outcomes/total outcomes = 4/8 = 0.5

A jeweler wants to combine a 60% gold alloy with a 20% gold alloy to make 1000 grams of 50% gold alloy. How many grams of 60% alloy should be used?
Answer:
750 grams of 60% alloy
Step-by-step explanation:
Define x = amount of 60% alloy and y = amount of 20% alloy
Equating the amounts of gold:
0.6x+0.2y = 1000(0.5)
Since there must be 1000 grams total:
x+y = 1000
Writing the 2 resulting equations together:
0.6x + 0.2y = 500
x + y = 1000
Multiply the first equation by 5:
3x + y = 2500
x + y = 1000
Subtracting the 2nd equation from the 1st:
2x = 1500
x = 750
Answer: 750 grams of 60% alloy

The value of k in the translated graph of f(x - h) + k is; k = 2
How to carry out Translations on Graphs?We are given the parent function of f(x) = x³.
Now, the point (0, 0) in the graph of f(x) is the point (3, 2) in the translated graph. Thus;
The rule of translation is;
(x, y) → (x + 3, y + 2)
That means;
The translation is 3 units to the right and 2 units up
The equation of the translated graph is equal to;

One evening, the candy counter at the Cineplex sold 532 buckets
of popcorn for $1,489.50. A large bucket sells for $2.25 and a
jumbo bucket sells for $3.75. How many jumbo buckets of
popcorn were sold?
Please help!!
Answer:
337 large buckets and 195 jumbo buckets were sold.
Step-by-step explanation:
x = the number of large buckets sold
y = the number of jumbo buckets sold
x + y = 532
(2.25x + 3.75y = 1489.50) x100 = 225x + 375y =148950
(x + y = 532) x -225 = -225x - 225y = -119700
+ 225x + 375y =148950
150y = 29250
y = 195
x + 195 = 532
x = 337
If a company reports operating profit of $70 million, earns net income of $50 million in year 8, has 20 million shares of common stock outstanding, pays a dividend of $1. 50 per share, and has annual interest costs of $15 million--all in year 8, then
The company's EPS for Year 8 would be $2.50 and its retained earnings for Year 8 would be $20 million
How do we calculate EPS and retained earnings?Note: The options for the questions are as follows:
A. the company's total earnings for Year 8 would be $10 million (net income of $50 million less interest costs of $10 million less dividend payments of $30 million = $10 million).
B. the company's EPS for Year 8 would be $2.50 and its retained earnings for Year 8 would be $20 million (net income of $50 million less dividend payments of $30 million).
C. the company's credit rating would be no less than an A because operating profit is seven times higher than annual interest costs.
D. the company's EPS for Year 8 would be $5.50 and its retained earnings for Year 8 would be $10million (net income of $50 million less interest costs of $10 million less dividend payments of $30million).
E. the company's EPS for Year 8 would be $1.50 (operating profit of $70 million less interest costs of$10 million, less dividend payments of $30 million= $30 million divided by 20 million shares).
The question can now be answered as follows:
From the question, we can calculate the following:
EPS = Net income / Number of shares of common stock outstanding = $50 million / 20 million = $2.50
Dividend payments = Number of shares of common stock outstanding * Dividend per share = 20 million * $1. 50 = $30 million
Retained earnings = Net income - Dividend payments = $50 million - $30 million = $20million
Therefore, the correct option is B. the company's EPS for Year 8 would be $2.50 and its retained earnings for Year 8 would be $20 million (net income of $50 million less dividend payments of $30 million).

What is the zero of f?
Answer:
x = -1
Step-by-step explanation:
(x1,y1) = (1,4) and m = 2
(y-y1)/(x-x1) = m
derive the linear function first before finding the zero.
(y-4)/(x-1) = 2
cross multiply
y-4 = 2(x-1)
y-4= 2x - 2
y = 2x - 2+4
y. = 2x + 2 is the linear equation
at y = 0 gives the zero
2x + 2 = 0
2x = -2
x = -2/2

The composite shape can be divided as shown into a trapezoid and a triangle. The area of the shape is the sum of the areas of those parts.
__
trapezoidThe top portion of the shape is marked as a trapezoid with bases 12 cm and 6 cm, and height 6 cm. Its area is given by ...
A = 1/2(b1 +b2)h
A = 1/2(12 cm +6 cm)(6 cm) = 1/2(18 cm)(6 cm) = 54 cm²

A = 1/2bh
A = 1/2(12 cm)(9 cm) = 54 cm²

Calculate the perimeter of the triangle for problems
B. Calculate the area of the triangle for problems
Answer:
To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c.
Answer:
1) 21.24cm
2)19.8ft
3)22.84mm [2.284cm]
Step-by-step explanation:
To calculate the perimeter of a triangle, add the length of its sides.
1) perimeter = 5.4+8.84+7
=> 5.4+8.84+7 = 21.24,
21.24cm
2) perimeter = 6.6 + 6.6 + 6.6 i.e 6.6* 3
=> 6.6 x 3 = 19.8
19.8ft
3) perimeter = 8.3 + 4.9 + 9.64
=> 8.3 + 4.9 + 9.64 = 22.84
22.84mm or 2.284cm
AREA
1) it's a right triangle,
=> Area of a right triangle = 1/2 × base × height.
=> here, base is a and height is b
=> a = 7, b = 5.4
=> now we multiply it,
=> 7*5.4 = 37.8
=> now multiply it with 1/2,
=> 1/2 x 37.8 = 37.8/2
=> 37.8/2 = 18.9
2) it's an equilateral triangle,
18.8620
the formula is √3 a^2/ 4
=> √3* 6.6^2/ 4
=> 75.4481/4 = 18.8620
3) 20.335
base = a = 8.3
height = b = 4.9
=> 8.3 * 4.9 = 40.68
=> 40.68/2 = 20.335

Carlos has at most $40 to spend on food for a barbeque. He wants to buy hot dogs and hamburgers and then
Alls for each. Carlos has already spent $31.50 on the hot dogs and hamburgers. Let r represent the amount of
noney that Carlos can spend on the rolls.
Write and solve an inequality.
Answer:
$8.50
Step-by-step explanation:
I don't know what Alls are, but if Carlos insists, we can calculate how much he can spend on Alls with the expression:
($31.50) + r [tex]\leq[/tex] $40
This says the sum of what Carlos has already spent (hot dogs and hamburgers) plus the amount he spends on Alls (rolls?), r, must be equal to or less than the $40 he has allowed himself to spend.
($31.50) + r [tex]\leq[/tex] $40
r [tex]\leq[/tex] $40 - $31.50
r [tex]\leq[/tex] $8.50
