Write an equation of the line in standard form with integer coefficients. the line through (-2, 2), (1, -4). O A. y+2x=-2 B. y+2x=6 C. 2y+x=2 D. 2y+x=-6
Answer:
A
Step-by-step explanation:
K=(y1-y2)/(x1-x2)=(2+4)/(-2-1)=-2
y=-2x+b
2=-2*-2+b
b=-2
y=-2x-2
y+2x=-2
The equation of the line in standard form with integer coefficients is → y + 2x = - 2.
What is the general equation of straight line?The general equation of straight line is -
y = mx + c
where 'm' represents the slope of the line and 'c' is the y - intercept.
Given is a line that passes through the points -
(-2, 2), (1, -4)
We can calculate the slope of the line using the two coordinates given -
(-2, 2), (1, -4). The slope will be -
m = (- 4 - 2)/(1 + 2)
m = -6/3
m = - 2
Assume that the equation of line is -
y = -2x + c
The line passes through the point (-2, 2), so we can write -
2 = -2 x -2 + c
2 = 4 + c
c = -2
So, we can write the equation of line as -
y = - 2x - 2
or
y + 2x = - 2
Therefore, the equation of the line in standard form with integer coefficients is → y + 2x = - 2.

Nuts.com sells raw almonds for $8 per pound and roasted pistachios for $9 per pound. Christopher spends $162, before taxes and shipping, to purchase 19 total pounds of nuts. How many pounds of pistachios did Christopher purchase?
Answer:
The pounds of roasted pistachios nuts Christopher purchases is 10 pounds
Step-by-step explanation:
The given parameters are;
The price of raw almonds at Nuts.com = $8 per pound
The price of roasted pistachios at Nuts.com = $9 per pound
The amount Christopher spends on Nuts = $162
The quantity of nuts Christopher purchase = 19 pounds
Let the pounds of raw almonds nuts Christopher purchases = X and the pounds of roasted pistachios nuts Christopher purchases = Y
∴ $8·X + $9·Y = $162...(1)
X + Y = 19...(2)
Making X the subject of the formula in equation (2), we have;
X = 19 - Y
Substituting the value X in equation (1) gives;
$8·(19 - Y) + $9·Y = $162
$152 - $8·Y + $9·Y = $162
$1·Y = $162 - $152 = $10
Y = $10/($1) = 10
Y = 10 pounds
The pounds of roasted pistachios nuts Christopher purchased = Y = 10
The pounds of roasted pistachios nuts Christopher purchases = 10 pounds
X = 19 - Y = 19 - 10 = 9
X = 9 pounds
The pounds of raw almonds nuts Christopher purchases = X = 9
The pounds of raw almonds nuts Christopher purchases = 9 pounds

Credit card sales (discount 3%) $ 8,600 Sales on account (3/15, n/60) $ 10,400 Sales returns related to sales on account were $500. All returns were made before payment. One-half of the remaining sales on account were paid within the discount period. The company treats all discounts and returns as contra-revenues. What amount will be reported on the income statement as net sales?
Answer:
$18192.50
Step-by-step explanation:
From the information given;
The amount that will be reported on the income statement as net sales can be computed as follows:
Particulars Amount ($)
Sales revenue $(8600 + 10400) $19000
Less: Credit card discounts
( contra - revenue) $(8600 × 3%) 258
Sales discounts
( contra - revenue)
[(10400 - 500)× 1/2 × 0.01 ] 49.50
Sales return and allowances
( contra - revenue ) 500
The net sale
(reported on the income statement) = $18192.50

what is the cost price of an article which when sold at Rs 10260 gives a profit of 20%?
Answer:
8208 Rs
Step-by-step explanation:
Rs: 10260
Profit 20%
10260 * 0.20 * 100% = 2052 Rs
10260 Rs - 2052 Rs = cost of product to be produced
CP: Rs 10260
Profit: 20%
Solution: 20% off 10260 is equal to (20 x 20) / 100 = 2052. So if you buy an item at $10260 with 20% discounts, you will pay $8208 and get 2052 cashback rewards
Gerardo’s texting plan cost $20 per month, +0.05 per text message that is sent or received. Amelia’s plan cost $10 per month and $0.25 per text. Using the graph below, which statement is true?
Step-by-step explanation:
Let's turn that into a linear system:
\{ {{y=0.05x+20} \atop {y=0.25x+10}} .{y=0.25x+10y=0.05x+20.
Set the equations equal to each other and solve:
0.05x+20=0.25x+100.05x+20=0.25x+10
0.2x=100.2x=10
x=50x=50
We then plug in to get yy :
0.25(50)+10=22.50.25(50)+10=22.5
The solution to the system is \{ {{x=50} \atop {y=22.5}} .{y=22.5x=50. .
Now, let's turn our attention to the statements.
The first one is false: Emilia's rate is higher, and the two plans cost the same at 50 texts, after which point Hiroto's plan becomes cheaper!
The second one is also false: we already figured out that the lines intersect at x=50x=50 .
The third statement is also false: as above, the lines intersect at x=50x=50 .
The fourth statement is true: the lines intersect at x=50x=50 .
In conclusion, the fourth statement - "Both plans cost the same when 50 texts are sent" - is true.

If an angle is half of its complement, then the measure of the LARGER angle will be
Answer:
60°
Step-by-step explanation:
Complementary angles sum 90°
a + b = 90° Eq. 1
b = a/2 Eq. 2
Replacing Eq. 2 in the Eq. 1
a + a/2 = 90
2a/2 + a/2 = 90
3a/2 = 90
a = 90*2/3
a = 60
from the Eq. 2
b = 60/2
b = 30
Check:
from the Eq. 1
60 + 30 = 90
Answer:
60>30
Then
The larger angle is:
60°
What number is 10 times greater than 0.03?
Answer:
0.3
Step-by-step explanation:
0.03×10= 0.3
Greater than would mean to multiply
The number is 10 times greater than 0.03 is 0.3 .
What does greater than means ?Greater than is used when a quantity or number is bigger or larger than the second or rest quantities or numbers.
According to the question
The number is 10 times greater than 0.03
i.e
As we need 10 times greater than 0.03
we will multiply 10 to 0.03
0.03 * 10 = 0.3
Hence, the number is 10 times greater than 0.03 is 0.3 .

Given problem:
What is the value of x = ?
Solution:
Angle on a straight line is 180°
Sum of angles in a triangle = 180°
Now to solve the problem, we need to find the two internal angles first;
For the first one;
let us say it is y;
163 + y = 180
y = 180 - 163 = 17°
For the second, assume it is z;
69 + z = 180
z = 180 -69 = 111°
The sum of the internal angles of the triangle;
y + z + 2x = 180
17 + 111 + 2x = 180
2x = 180 - 128
2x = 52
x = [tex]\frac{52}{2}[/tex] = 26
The value of x is 26

HELP ASAPP... Find the volume of a cylinder with a radius of 5 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest tenth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank)
Answer:
1177.5 in³
Step-by-step explanation:
To find the volume of a cylinder, you need to do this:
V= π r² h
Substitute in 3.14, 5, and 15
V= 3.14 x 5² x 15
Multiply 5 by itself
V= 3.14 x 25 x 15
Multiply 3.14 and 25
V= 78.5 x 15
Multiply 78.5 x 15 to get your answer:
V= 1177.5 in³

Calculate the slope between the points: (4, -9) and (5, 1)
a
m=10
b
m=1/10
с
m=-10
d
m=-1/10
Answer:
The answer is A- m=10
Step-by-step explanation:
The way to find slope is known as "Rise over Run" meaning the increase of Y over the increase of X. The increase of Y is 10 because 1 - (-9) = 10. The increase of X is 1 because 5 - 4 = 1. 10 over 1, or 10 / 1, equals 10.
