What is the range of this relation?
(8,-9)
(5, -3)
(-4, 6)
(-3, -2)
(6,8)
(8,6)
Answers
Answer:
Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}
Step-by-step explanation:
{(2,4), (8,-3), (-5,-1), (4,6), (6,7), (9,0)}
The domain is the input and the range is the output
domain is { 2,8,-5,4,6,9} and the range is {4,-3,-1,6,7,0}
We put the numbers in order from smallest to largest
Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}
Answer:
(-9,-3,6,-2,8,6) is the answer as the range is always the "second pair" of numbers in any relation.

ssion 4 x (20 – 1) if a = 3?
What the answer?
Answers
Answer:
20Step-by-step explanation:
Question:4 × (2a - 1)
Given value:a = 3
Solution:4 × (2a - 1)
= 4 × (2(3) - 1) [Substituting the value of a=3]
= 4 × (6 - 1) [Simplification]
= 4 × 5 [On further simplification]
= 20
Hence, 20 is the required answer.
Answer:
20
Step-by-step explanation:
a = 3
4 × (2a - 1) =
= 4 × (2 × 3 - 1)
= 4 × (6 - 1)

9z - 3x
-3x - 9z
Answers
Answer:
x = 1.27
y = 5.18
Step-by-step explanation:
to solve this system of equation by simultaneous equation we say that let
3x+y=9.............................. equation 1
-5x+2y=4 .......................... equation 2
from equation 1
3x+y=9.............................. equation 1
y = 9 -3x.............................. equation 3
substitute the value of y = 9 -3x into equation 2
-5x+2y=4 .......................... equation 2
-5x + 2( 9 -3x) = 4
-5x + 18 - 6x = 4
collect the like terms
18 - 4 = 6x + 5x
14 = 11x
divide both side by 11
14/11 = 11x/11
x = 14/11
x = 1.27
put the value of x = 1.27 into equation 3
y = 9 -3x.............................. equation 3
y = 9 - 3( 1.27)
y = 9 - 3.82
y = 5.18
to check if you are correct put the value of x and y into either equation 1 or equation 2.
3x+y=9.............................. equation 1
3( 1.27) + 5.18 = 9
3.81 + 5.18 = 9
9 = 9
