Answer:
the two numbers are 3 and -4
Step-by-step explanation:
Product: xy = -12, or x = -12/y
Sum: x + y = -1, or -12/y + y = -1
Let's multiply all three terms by y to eliminate the fractional terms:
-12 + y^2 = -y, or
y^2 + y - 12 = 0
This factors into (y + 4)(y - 3) = 0, yielding y = -4 and y = 3.
Earlier we found that x = -12/y. Here, if we choose y = -4, x = -12/(-4) = 3
and so the two numbers are 3 and -4. Note that 3(-4) = -12, as required, and that 3 - 4 = -1, also as required.

1. The perimeter of a square is 18.4 m. What is its area?
Answer:
A ≈ 21.16m²
Step-by-step explanation:
Answer:
21.16 m^2
Step-by-step explanation:
If the perimeter is 18.4 m, then the length of a side is 18.4 m / 4, or 4.6 m.
Then the area of the square is (4.6 m)^2, or 21.16 m^2

5. 1-cos²θ 6. sec²θ-1
7. csc²θ-cot²θ 8. 1-sin²θ
Answer:
Step-by-step explanation:
1, sec theta * sin theta = 1/cos * sin = sin/cos =tan theta
2. cosec theta * cos theta = 1/ sin * cos = cos/sin = cot theta
3, tan theta * cosec theta =sin/cos * 1/sin = 1/cos
4, cot theta * sec theta = cos /sin * 1/cos= 1/sin
5, 1 - cos^2 theta = sin ^2 theta
6, sec^2 theta - 1 =tan ^2 theta
7 , cosec^2 theta - cot^2 theta = 1

How many gallons of paint will you need to paint a bedroom that is 10 ft by 14 ft with walls that are 7 1/2 ft high? The walls will need two coats to cover the old paint.
How many gallons of paint are needed to paint the ceiling of the same room in the last question, one coat of paint will suffice.
you have two walls that are 10 by 7.5 so 75 feet ^2 in area each
you have another two walls that are 14 by 7.5 so 105 feet^ 2 each
so all of that together is 360 feet^2 to cover for one coating, so you have 720 feet^2 to cover for 2 coats on the walls. so take that and divide it by the area that one gallon would cover, then round up giving you how many gallons you would have to buy
for the ceiling you do the same, the area is 140 and you only need one coat

determine the range of the function graphed above
Answer: A
Step-by-step explanation:
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values.
The possible values of y are [-infinity,4], so the answer is A

Aitanacompreparaaitana compra para su fiesta de cumpleaños 5 litros de refresco y vasos de plastico de una capacidad de 250 metros cubicos ¿cuantos vasos podria servir en total?
Answer:
None
Step-by-step explanation:
In this case we must pass everything to the same unit of measure, we know that the total is 5 liters of soft drink and that each plastic cup has a capacity of 250 cubic meters.
We know that 1 liter is equivalent to 0.001 cubic meters, therefore we will pass the cubic meters of the plastic cup to liters, like this:
250 m ^ 3 * 1 L / 0.001 m ^ 3 = 250,000 L
Therefore we realize that the glass has a very large capacity, which suggests that there is an error in the statement, maybe it is not a cubic meter but a cubic centimeter, but as it is, it cannot serve any plastic cup because the capacity of this cup is very large with respect to the total amount of soft drink.

If 3m+2n=16 and m−2n=0, then what is the value of m?
Answer:
m= 4
Step-by-step explanation:
3m +2n= 16 -----(1)
m -2n= 0 -----(2)
From (2):
m= 2n -----(3) (+2n on both sides)
subst. (3) into (1):
3(2n) +2n= 16
6n +2n= 16
8n= 16 (simplify)

m= 4
Sophia just graduated from college and is living on her own. She only wants to
spend about ten percent of her net income on food. She earns a net income of
$2,450 each month. Last week, she tracked her food spending and found she
spends about $75 a week on groceries. Is she meeting the ten percent?
Answer:
Sophia's monthly spent on food is $300 while she wants to spend $245.
As her real monthly spent is greater than what she wants, she is not meeting the 10% criteria. In fact, she exceed her budget for month
Step-by-step explanation:
Net income of Sophia = $2,450
% of money she wants to spend on food = 10% of Net income of Sophia
thus,
Amount of money she wants to spend on food in $
= 10% of $2,450
= 10/100 * $2,450 = $245
Hence, Sophia wants to spend $245 in a month on food.
__________________________
it is given that last week she spent $75 on food
thus, weekly spent on food = $75
as there are 4 weeks in a months
money spent by her in 4 weeks = $75* 4 = $300
Thus, her monthly spent on food is $300 while she wants to spend $245.
As her real monthly spent is greater than what she wants, she is not meeting the 10% criteria. In fact, she exceed her budget for month

What is the measure of angle Y, in degrees?
Answer:
The answer would be 116
Step-by-step explanation:
The angles X and Z would be equal at 32 so multiply them by 2 and you would get 64 subtract 64 from 180 and you would get 116
Answer:
Y =116
Step-by-step explanation:
We know that angle Z = angle X since they are base angles and the sides are the same length
The sum of the angles of a triangle are 180
X+Y+Z = 180
32+ Y + 32 = 180
64+Y=180
Y = 180-64
Y =116
A company pays each of its two office employees each Friday at the rate of $120 per day for a five-day week that begins on Monday. If the monthly accounting period ends on Tuesday and the employees worked on both Monday and Tuesday, the month-end adjusting entry to record the salaries earned but unpaid is:
Answer:
Debit Salaries Expense $480 and credit Salaries Payable $480
Step-by-step explanation:
Firstly, we will need to calculate the salary expense of the company on these two employees.
Mathematically, that would be
2 employees * 2 days * 120/employee/day = 2 * 2 * 120 = $480
Thus, the month-end adjusting entry to record the salaries earned but unpaid is that salaries expense will be debited $480 and salaries payable will be credited $480
