Answer:
Simplified the expression
−
15 + 10
g
Step-by-step explanation:
I believe it is 22 units but not positive hopefully some one else can throw out what they know so you can it can be definitely the right answer
Old Condition
Numerator = n = x
denominator = d = 2n + 3
New Condition
(x - 1) /(2x + 3 - 1) = 7 / 16
(x - 1) / (2x + 2) = 7 / 16
Cross multiply and solve
16*(x - 1) = 7 * (2x + 2) Remove the brackets.
16x - 16 = 14x + 14 Add 16 to both sides.
16x = 14x + 30 Subtract 14x from both sides.
2x = 30 Divide by 2
x = 15
You really should check this.
Original fraction
15/33
Now subtract 1 from the top and bottom.
14/32 Divide both by 2
7 / 16 which checks out perfectly
Answer:
4 and 8
Step-by-step explanation:
(a)
f(0) for x = 0 , that is the interval x < 5, thus
f(0) = x + 4 = 0 + 4 = 4
(b)
f(6) for x = 6 , that is the interval 5 ≤ x < 7, thus
f(6) = 8
