Answer:
8, -8
Step-by-step explanation:
Let's say that x is the larger number,
x - y = 16
y = x - 16
xy = P where P is a minimum
x(x-16) = P.
(We can find the vertex, which is the minimum, by writing it in vertex format)
Completing square:
x2 - 16x = P
x2 - 16x + 64 = P + 64
(x - 8)2 = P + 64.
So,
x = 8 and -8
(8 - -8 -> 8 + 8 = 16)

What is the domain and range of the function below
The kitchen of a house is of size 15ft x 12ft. Find the cost of tiling the wall at all sides 5 ft from the base at the rate of Rs. 120/sq ft.
Answer:
20400RS
Step-by-step explanation:
Given, Kitchen Size = 15ft * 12ft wall height to be tiled = 5 ft so area of focer walls
= 2* 15+2*5*12
= 150+120=170ft.
Rate is 120/ sq*ft here rate
= 120*170
= 20400RS
The equation y = -4X -1 Has a slope of _______ possible answer choices: -4,-1, no slope and 0) and a y-intercept of possible answer choices: -4, -1 0 and no y-intercept)_______?
Answer:
slope = - 4 , y- intercept = - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 4x - 1 ← is in slope- intercept form
with slope m = - 4 and y- intercept c = - 1
Answer:
-4 then -1
Step-by-step explanation:
The number behind the x value is the gradient and the last number is the y - intercept.
Graph the line passing though (-6,-1) whose slope is m= -4/3
y=-4/3x-9

The 14-ounce box is cheaper at a cost of $2.74 than the 10-ounce box.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.
For example 4/2 = 2
First, we have to find the price for each ounce.
So for the 10-ounce box:
⇒ 2.12 / 10
Apply the division operation,
⇒ $0.212 per ounce.
Now for the 14-ounce box:
⇒ 2.74/ 14
Apply the division operation,
⇒ $0.19 per ounce.
Here the cost of the 14-ounce box is less than the 10-ounce box as 0.19 < 0.21
Therefore, the 14-ounce box is cheaper at a cost of $2.74.

A SQUARE RECTANGULAR PRISM (BASE IS A SQUARE) HAS A
VOLUME OF 38 CU. IN. THE HEIGHT IS 10 LESS THAN THE AREA
OF THE BASE. WHAT IS THE HEIGHT? NO UNITS.
The height of the prism [tex]\approx 2.9[/tex]
The whole volume of the prism is
[tex]\text{Volume} = \text{Area of base}\times \text{Height}[/tex]
Here, the volume is 38 cu. in.
From the question, the area and the height are related as follows;
[tex]\text{Height} = \text{Area} - 10 \implies \text{Height + 10} =\text{Area}[/tex]
Substituting this into the formula for the volume, we get
[tex]\text{Volume}=(\text{Height} +10)\times \text{Height}=38\\\\\text{Height}^2 + 10\times\text{Height}=38\\\\\text{Height}^2 + 10\times\text{Height}-38=0[/tex]
If the above quadratic equation is solved for the height, we get
[tex]\text{Height}\approx 2.9[/tex]
(We can't take the other solution since height has to be greater than zero)

15 POINTS AND BRAINLIEST, im to lazy and this was do two weeks ago please help.
Answer:
$1.79
Step-by-step explanation:
h + 5f = 8.74 → (1)
2h + 3f = 7.75 → (2)
Multiplying (1) by 3 and (2) by - 5 and adding will eliminate f
3h + 15f = 26.22 → (3)
- 10h - 15f = - 38.75 → (4)
Add (3) and (4) term by term to eliminate f
- 7h = - 12.53 ( divide both sides by - 7 )
h = 1.79

Answer:
GCF = 5
Step-by-step explanation:
Reason being that all are divisible my 5 and 10 cannot be used because it makes a fraction which is not how the GCF can be found.
Math:
50 = 5 * 10 or 25 * 2 or 50 * 1
15 = 5 *3 or 15* 1
10 = 5 * 2 or 10 * 1
Only thing that is the same is 5, thus 5 is the GCF.

hi can someone help me....can't get the answer.....you need to find a+b+c+d
Answer:
B) 306°
Step-by-step explanation:
1. Pentagons have a sum of interior angles of 540°
2. Triangles have a sum of interior angles of 180°
3. Knowing that triangle EFA is isosceles, we know that
<FEA = *<FAE, so they are equal to: (180° - <F) /2 = (180° - 36°) / 2
= 144° / 2
= 72°
4. m<A + m<B + m<C + m<D + m<E = 540°
It is also given that **m<D = 90°,
so therefore m<A + m<B + m<C + m<E = 450°
5. Now to find a+b+c+d (m<a + m<b + m< c+ m<d),
m<a = m<E - 72° and m<d = m<A - 72°
This means that
m<a + m<b + m< c+ m<d = (m<A - 72°) + m<B + m<C + (m<E - 72°) = 450°
6. Finally,
m<a + m<b + m< c+ m<d = 450° - 72° - 72° = 306°
EXTRAS
* < is an angle symbol
** m<D means measure of angle D

Write two expressions for this situation, one representing the cost per customer and the other representing the average number of customers. Assume that x represents the number of $1 increases in the cost of the buffet.
Enter the correct answer in the box. Type the cost expression on the first line and the customer expression on the second line.
The expressions that can be used to derive the quadratic inequality for the
situation are;
Cost: 10 + xCustomers: 16 - 2·xReasons:
The parameters of the restaurant are;
The charge per buffet = $10
Number of customers that choose the buffet every hour = 16 customers
For an increase in $1 in the cost of the buffet, the customers decrease by 2 per each hour.
The required minimum revenue per hour = $130
Required:
The situation is to be modelled as a quadratic inequality.
Two expressions for the situation, one for the cost and one for the
customers.
Assumption: x = The number of $1 increases in the cost of the buffet
Solution:
The expressions are;
The cost of the buffet for an increase in x dollars is; Cost = 10 + xThe expression for the customers when the cost increases by x amount is; Customer = 16 - 2·xWhich gives;
Cost × Customers = Revenue
The inequality that models the situation is therefore;
(10 + x) × (16 - 2·x) ≥ 130
Which gives;
160 - 20·x + 16·x - 2·x² ≥ 130
160 - 4·x - 2·x² ≥ 130
