2. Not True
3. Not True
4. Not True
5. True
Step-by-step explanation:
As given,
1.
2 + 3 = 9
⇒ 5 = 9
Not True
2.
4 > 5 + 7
⇒4 > 12
Not True
3.
9 = 12 + 2
⇒9 = 14
Not True
4.
2 - 3 ≥ 2
-1 ≥ 2
Not True
5.
61 ≠ 5 - 12
⇒61 ≠ -7
True
Answer:
I) f + g = 10/3
II) 4f + 2g = 20/3
III) f = 2 and g = 4/3
Step-by-step explanation:
From the chart,
P = 25
q = 40
The total number of one centimeter lines in the first n diagrams is given by the expression
2/3n^3 + fn^2 + gn.
When n = 1, the total number of line = 4. So,
2/3(1)^3 + f(1)^2 + g(1) = 4
2/3 + f + g = 4
Make f+g the subject of formula
f + g = 4 - 2/3
f + g = (12 - 2)/3
f + g = 10/3 ......(1)
When n = 2
Total number of line = 12
2/3(2)^3 + f(2)^2 + g(2) = 12
2/3×8 + 4f + 2g = 12
16/3 + 4f + 2g = 12
4f + 2g = 12 - 16/3
4f + 2g = (36 - 16)/3
4f + 2g = 20/3 ......(2)
(iii) To find the values of f and g, solve equation 1 and 2 simultaneously
f + g = 10/3 × 2
4f + 2g = 32/3
2f + 2g = 20/3
4f + 2g = 32/3
- 2f = - 12/3
f = 12/6
f = 2
Substitutes f in equation 1
f + g = 10/3
2 + g = 10/3
g = 10/3 - 2
g = (10 - 6)/3
g = 4/3
First we put the sentence into a function
9/10 * x + 6= 51Well then we solve<span>.</span><span>9/10* x= 51-6
9/10*x= 45
(<span>for</span> me is easier to make the fraction into a decimal...)
0.9*x= 45
x=45/0.9
x= 50
We check
9/10 * 50 + 6= 51
45+6=51
51=51
So the answer is x= 50</span>
