Answer:
y + 3 = [tex]\frac{2}{3}[/tex] ( x - 9 )
Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
y - [tex]y_{1}[/tex] = [tex]\frac{2}{3}[/tex] ( x - [tex]x_{1}[/tex] )
y = mx + b
~~~~~~~~~~
( 9 , - 3 )
y - ( - 3 ) = [tex]\frac{2}{3}[/tex] ( x - 9 )
y + 3 = [tex]\frac{2}{3}[/tex] ( x - 9 )

Answer:
(a) 18.5ft
(b) 388.5 ft²
Step-by-step explanation:
(a)
She has 79ft of fence = the perimeter will be 79.
Perimeter of a rectangle = 2(length) +2(width)
79 = 2(21)+2(width)
2(width) = 79 - 42
width = 37/2
width = 18.5ft
(b)
Area of a rectangle = (length)(width) = (21)(18.5) = 388.5 ft²

Identify the distance between points (3,7,1) and (9,6,7), and identify the midpoint of the segment for which these are the endpoints. Round to the nearest tenth, if necessary.
Step-by-step explanation:
[tex]range = (3,7,1) - (9,6,7) \\ = ( - 6,1, - 6) \\ distance = \sqrt{ {x}^{2} + {y}^{2} + {z}^{2} } \\ = \sqrt{ {( - 6)}^{2} + {1}^{2} + {( - 6)}^{2} } \\ = \sqrt{73} \\ = 8.5 \: units[/tex]
The distance between points (3,7,1) and (9,6,7) is 8.54 units and the midpoint of the segment is (6, 6.5, 4).
What is Distance?The length along a line or line segment between two points on the line or line segment.
Distance=√(x₂-x₁)²+(y₂-y₁)²
We need to find the distance between points (3,7,1) and (9,6,7).
Distance=√(9-3)²+(6-7)²+(7-1)²
=√6²+(-1)²+(6)²
=√36+1+36
=√73
=8.54 units
So the distance between the two points is approximately 8.5 units.
To find the midpoint of the segment between the two points, we use the midpoint formula:
midpoint = ((x₁+x₂)/2, (y₁+y₂)/2, (z₁+z₂)/2)
Using the given points, we have:
midpoint = ((3+9)/2, (7+6)/2, (1+7)/2)
= (6, 6.5, 4)
So the midpoint of the segment is (6, 6.5, 4).
Hence, the distance between points (3,7,1) and (9,6,7) is 8.54 units and the midpoint of the segment is (6, 6.5, 4).

Answer:
The awnswer is b c and e
Step-by-step explanation:
I submmited it and got it right hope this helps :D
The shapes which have all the properties shown are C. Rectangle and E. Square.
What are Isosceles Triangles?Isosceles triangles are defined as the triangles for which two sides or two angles are equal to each other.
Given properties are,
At least 2 sides of equal length
2 pairs of parallel sides
At least 2 right angles
Since the property includes that 2 pairs of parallel sides, it must contain 4 sides in total.
So triangle can't be a possible shape.
Parallelogram can't also be possible since there are no right angles.
Only right trapezoids are possible since the other ones will not have al least two right angles.
Rectangle and square are possible.
Hence the correct shapes are Rectangle and Square.

Marcia is mixing lemonade. She use 3 parts water to 1 part syrup. If she has 9 parts water, how much syrup will she need to complete the mixture?
Answer:
if Marcia uses 9 parts water, that mean she will have to use 3 parts syrup
Step-by-step explanation:
this is ratios,
so to find out how many syrup she needs, you need to see how much she used water from the original recipe
so:
9 ÷ 3 = 3
so she multiplied three to get to nine, so we have to do the same to the syrup
_ ÷ 1 = 3
or:
3 × 1 = 3
so the answer is 3
