Answer:
Image result for 44. Consider all rectangles with an area of 182 square feet. Let's Be the length of one side of such a rectangle a) Express the perimeter as a function of b) Use the graphing calculator to find the dimensions of the rectangle that has the least perimeter. What is the least perimeter?
Divide the area of the rectangle by the width in order to find the length of 14 feet. The perimeter is the sum of the side lengths, which in this case is 14 feet + 4 feet +14 feet + 4 feet, or 36 feet.
if 3(y+12)=24 find the value of 1/8y
Answer:
-1/2
Step-by-step explanation:
3(y + 12) = 24
3y + 36 = 24
3y = 24 - 36
3y = -12
y = -12/3
y = -4
Value of 1/8 × y
1/8 × (-4)
-4/8
-1/2
Answer:
-1/2
Step-by-step explanation:
3(y + 12) = 24
~Simplify left side
3y + 36 = 24
~Subtract 36 to both sides
3y = -12
~Divide 3 to both sides
y = -4
~Now substitute in 1/8y
1/8(-4)
= -1/2

3/2x-2/3x=2
Please help
Answer:
x = 12/5 or 2.4
Step-by-step explanation:
To solve this equation:
We have to combine like terms.3/2x-2/3x=2
5/6x = 2
Now, we have to isolate the x variable by dividing 5/6 on both sides.5/6x = 2
x = 12/5

What is 15 percent of 1135? Also Explain how you came up with your solution and the actions you took.
Answer:
170.25
Step-by-step explanation:
15% x 1135
15/100 x 1135
170.25
Hello :D
10% of 1135 = 1135/10 = 113.5
5% of 1135 = 113.5/2 = 56.75
15% of 1135 = 113.5 + 56.75 = 170.25
Answer = 170.25

Answer:
g(0)=2, g(1)=-3 ,g(-3) =29
Step-by-step explanation:
x²-6x+2
g(0) = 0²-6(0)+2
= 0-0+2
= 2
g(1) =1²-6(1) +2
=1-6+2
=-3
g(-3) =(-3)²-6(-3) +2

|3x-8|+7=2
Answer:
No solution
Step-by-step explanation:
To solve first you need to isolate the absolute value sign. Do this by subtracting 7 from each side.
|3x-8| = -5Now an expression inside absolute value bars is set to a negative. Since absolute value makes terms and expressions positive, there is no x-value that could make this true. Therefore, there are no solutions.
[tex]\\ \tt\Rrightarrow |3x-8|+7=2[/tex]
[tex]\\ \tt\Rrightarrow |3x-8|=2-7[/tex]
[tex]\\ \tt\Rrightarrow |3x-8|=-5[/tex]
Because of absolute vale there is no solution

5(1+2x)= 5 +10x =10x + 5
Answer:
Yes, they are eqivelant.
Step-by-step explanation:
5(1+2x) and 10x+5
The first step is to set them equal to each other, to see if they are equivelent.
5(1+2x) = 10x+5
Distribute the 5 to both terms in the parentheses by multiplying.
5(1) + 5(2x) = 10x +5
5 + 10x = 10x +5
The communative property of addition proves that these are equal.

Which translation vectors could have been used for the pair of figures?
select EACH correct answer
Answer:
The translation vector can be drawn on the coordinate grid or written as
\vec{v}=\langle a,b\rangle
v
=⟨a,b⟩
. For example, a translation vector that moves a figure
3
3
units right and
2
2
units down can be represented mathematically as
\vec{v}=\langle3,-2\rangle
v
=⟨3,−2⟩
, or graphically as
It doesn’t matter where the vector is positioned in the plane. In this figure, the vector starts at
(1,1)
(1,1)
and ends at
(4,-1)
(4,−1)
. But the initial point and terminal point of the vector are irrelevant. What matters is the length of the vector and the direction in which it points, so all you have to look at is how many units the vector moves in the
y
y
-direction and how many units the vector moves in the
x
x
-direction.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
On Friday= 26 pounds Apples sold.
On Saturday = 7 x 26= 182 pounds apples sold.
On Sunday = 32 pounds
Then, In three days total pounds of apples sold
= 26 + 182 + 32
= 240 pounds
Hence, in 3 days 240 pounds apples sold.
