The correct answer is 2 so Grace was the correct student
Answer:
5/27
Step-by-step explanation:
We times/multiply the numerators together and we times/multiply the denominators together:
Numerator:
-5×-2=10 (2 negatives multiplied makes a positive outcome - rules of integers)
Denominator:
6×9=54
10/54 would be our answer but to simplify we can divide top and bottom by 2 to get a simplified fraction
10/54÷2=5/27
This is our final answer
F(x) = 2x - 4
f(2 ≤ x) = 2(2 ≤ x) - 4
f(x ≥ 2) = 2(x ≥ 2) - 4
f(x ≥ 2) = 2(x) ≥ 2(2) - 4
f(x ≥ 2) = 2x ≥ 4 - 4
f(x ≥ 2) = 2x ≥ 0
f(x ≥ 2) = x ≥ 0
f(x) = 2x - 4
f(x ≤ 6) = 2(x ≤ 6) - 4
f(x ≤ 6) = 2(x) ≤ 2(6) - 4
f(x ≤ 6) = 2x ≤ 12 - 4
f(x ≤ 6) = 2x ≤ 8
f(x ≤ 6) = x ≤ 4
Answer:
( 
, 3 )
Step-by-step explanation:
Given the 2 equations
y = 9x → (1)
6x - y = - 1 → (2)
Substitute y = 9x into (2)
6x - 9x = - 1, that is
- 3x = - 1 ( divide both sides by - 3 )
x =
Substitute x = into (1) for corresponding value of y
y = 9 × = 3
Solution is ( , 3 )
Answer:
it will be c, x=8.5
Step-by-step explanation:
-18+4x=-4x+50
4x+4x=18+50
8x=68
x=8.5
