Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
3x +2y = 5 → (1)
x - 2y = - 1 → (2)
Adding the 2 equations term by term will eliminate the term in y, that is
(3x + x) + (2y - 2y) = (5 - 1)
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 in either of the 2 equations and solve for y
Substituting in (1)
3(1) + 2y = 5
3 + 2y = 5 ( subtract 3 from both sides )
2y = 2 ( divide both sides by 2 )
y = 1
Solution is (1, 1 )
First multiply 20 by 17
second multiply 8 by 17
then you have to add 20 by 8 which will give you 28
so,476 divided by 17 gives you 28
1) 5, 5 1/2, 2) 5, 6, 8, 3) 3, i know this because the graph shows three dots over the number 6 on the graph, 4) 5.5, 6, 8, i know this because all the other pearl sizes occurred more often
Well the midpoint formula to find the coordinates is ( (x₂ + x₁)/2 , (y₂ -+ y₁)/2 )
Basically you find the average of each points to find the midpoint. Well we already have the midpoint so we plug our numbers in with variables to find the other point. Let's start with the x value of coordinate L:
(2 + x₁)/2 = -4 the 2 came from point J and the -4 came from the midpoint k.
2+ x₁ = -8
x₁ = -10 this is the x coordinate of point L. Let's find the y
(-1 + y₁)/2 = 3
-1 + y₁ = 6
y₁ = 7 this is the y coordinate of L
L's coordinate is (-10, 7)
The domain is all the x values so {2,-4, 1, 2, -1}
The range is all the y values so {1, 5, 7, -3, 2}
Yes, it is a function because each item in the domain matches one item in the ranges.
