Answers:
2x - 6y = 8 -> x = 4 + 3y
-3x + 9y = 12 -> x = -4 + 3y
Answer:
a. O = h - 40
b. 0, 4, 8, 12
Step-by-step explanation:
Let numver of overtime hours Jim workes for defined by O.
Standard working hours in a week for Jim = 40 Hours
If Jim is working for h hours then number of overtime hours will be given as difference between total hours he worked and standard working hours in a week.
⇒ O = h - 40
now, if jim has worked for 40, 44, 48 and 52 hours then his over time for all these cases will be
O = 40 - 40 = 0 Hours
O = 44 - 40 = 4 Hours
O = 48 - 40 = 8 Hours
O = 52 - 40 = 12 Hours respectively.
Answer: 10
Explanation: you need to first find the area of the triangle which would be 2x2x1/2 then you find the area of the rectangle which is 4x2 so 8+2=10
Answer:
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
Step-by-step explanation:
0 = – 3x2 – 2x + 6
It can still be written as
– 3x2 – 2x + 6 =0
Quadratic formula=
-b+or-√b^2-4ac/2a
Where
a=-3
b=-2
c=6
x= -(-2)+ or-√(-2)^2-4(-3)(6)/2(-3)
x = StartFraction negative
(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
The answer to ur question is 4
