Answers
Answer:
they are 13 points away from eachother
Step-by-step explanation:
count up or down then left or right
Answer:
13 units.
Step-by-step explanation:
Distance = √[(x2-x1)^2 + (y2-y1)^2] where (x1,y1) and (x2,y2) are the 2 points
So here the distance = √(-4 - -4)^2 + (8 - -5)^2)
√(0 + 13^2)

Step: Solve2x+y=11for y:
2x+y=11
2x+y+−2x=11+−2x(Add -2x to both sides)

Step-by-step explanation:
[tex]area \: of \: rectangle = length \times \: width[/tex]
Given
[tex]l = 2w - 3[/tex]
using this
[tex]area = l \times w = (2w - 3)(w) = 27[/tex]
[tex]2 {w}^{2} - 3w = 27[/tex]
[tex]2 {w}^{2} - 3w - 27 = 0[/tex]
[tex]2 {w}^{2} - 9w + 6w - 27 = 0[/tex]
[tex]2w(w - 4.5) + 6(w - 4.5) = 0[/tex]
[tex](2w + 6)(w - 4.5) = 0[/tex]
[tex]w = - 3 \: \: or \: \: w= 4.5[/tex]
Since size cannot be negative therefore
[tex]w = 4.5cm[/tex]
[tex]l = 2w - 3 = 9 - 3 = 6[/tex]
Hence length of the rectangle=6m
width of the rectangle=4.5m
Answer:
Let length and breadth of rectangle be x metres and y metres respectively.
xy = 27 ---- eqn 1
x = 2y-3 ---- eqn 2
Sub eqn 2 into eqn 1:
(2y-3) × y = 27
2y² - 3y = 27
2y² - 3y - 27 = 0
(y+3)(2y-9) = 0
y+3=0 or 2y-9=0
y=-3 (rejected) 2y=9
y=4.5
Sub y=4.4 into eqn 2:
x = 2(4.5) - 3
= 6
Hence,
length of rectangle = x metres
= 6m
breadth of rectangle = y metres
= 4.5m

Points R(-6,-5),S(-2,-5) and T(-2,n) are plotted in the coordinate plane. The distance between points R and S is half the distance between points S and T. The value of n could be blank or blank.
Answers
The square of the distance between two points is the sum of the squares of the difference between two coordinates. The value of n can be -13 or 3.
What is the distance between two points?The distance between two points is given by the formula,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
As it is given that the distance between points R and S is half the distance between points S and T.
[tex]2(RS) = ST[/tex]
Now, the distance between RS can be written as,
[tex]RS=\sqrt{[-6-(-2)]^2+[-5-(-5)]^2}\\RS = \sqrt{(-6+2)^2+(0)^2}\\RS = \sqrt{16}\\RS = \pm 4[/tex]
Further, we can write,
[tex]2(RS) = ST\\\\2(\pm 4) = \sqrt{[-2-(-2)]^2+[-5-n]^2}\\\\\pm 8 = \sqrt{(0)^2+(-5-n)^2}\\\\\pm 8^2=(-5-n)^2\\\\\pm8=(-5-n)\\\\[/tex]

The perimeter of a rectangle is 24. write the function that describes its area in terms of one of the sides. if one side is a, the formula will be S= ____
Answers
The area of the rectangle whose perimeter is 24 units and one side is of 'a' units, in terms of 'a' is given as: S = a(12-a) unit²
How to find the area of a rectangle?Suppose that the two adjacent sides of a rectangle be of 'a' units and 'b' unit lengths.
Then, we get the area of that rectangle as:
[tex]S = a \times b \: \rm unit^2[/tex]
For this case, we're specfied that:
One of the side of the considered rectangle is of 'a' units length.The perimeter of the considered rectangle = 24 unitsLet the other side (adjacent) be of 'b' units length
Then, as perimeter of a rectangle = 2(sum of lengths of one pair of adjacent sides of the rectangle)
Therefore, we get:
[tex]24 = 2(a+b)\\\text{Dividing both the sides by 2}\\12 = a + b\\b = 12 - a[/tex]
We expressed 'b' in terms of 'a' so that we can represent the area of the considered rectangle in terms of 'a' alone.
The area of the rectangle is:
[tex]S =a \times b = a \times (12 - a) \: \rm unit^2[/tex]
Thus, the area of the rectangle whose perimeter is 24 units and one side is of 'a' units, in terms of 'a' is given as: S = a(12-a) unit²

A couch is discounted by $299. If the original price is $1250 , estimate the sale by price by first rounding each number to the nearest hundred
Answers
Answer: $950
1250-299=951
round off to nearest hundred, $950
The estimated sale price of the couch after rounding each number to the nearest hundred is $901.
To estimate the sale price of the couch, we first need to round each number to the nearest hundred.
Original price: $1250
Rounded to the nearest hundred: $1200
Discount amount: $299
Now, let's calculate the estimated sale price by subtracting the discount from the rounded original price:
Estimated Sale Price = Rounded Original Price - Discount Amount
Estimated Sale Price = $1200 - $299
Estimated Sale Price = $901
The estimated sale price of the couch after rounding each number to the nearest hundred is $901.

Answers
Answer:
2.5 ft wide8 ft longStep-by-step explanation:
The given relation between length and width can be used to write an expression for area. The equation setting that equal to the given area can be solved to find the shed dimensions.
__
Given relationLet x represent the width of the shed. Then the length is (2x+3), and the area is ...
A = LW
20 = (2x+3)(x) . . . . . area of the shed
__
SolutionCompleting the square gives ...
2x² +3x +1.125 = 21.125 . . . . . . add 2(9/16) to both sides
2(x +0.75)² = 21.125 . . . . . . . write as a square
x +0.75 = √10.5625 . . . . . divide by 2, take the square root
x = -0.75 +3.25 = 2.50 . . . . . subtract 0.75, keep the positive solution
The width of the shed is 2.5 feet; the length is 2(2.5)+3 = 8 feet.
