Answer:
If a is 1.. we substitute one in every a in g(a)
4 * 1 + 16
4+ 16 = 20
g(a)= 20
f(20)
-16 + 20 = 4
and 4/4 = 1
so f (g (a)) = a
Step-by-step explanation:
Answer:
The sign is negative
Step-by-step explanation:
Given
Required
Determine the sign
The expression can be split into 3 factors
If x > 0 then x is positive and If y < 0 then y is negative
So, the expression becomes:
<em />
Leave only signs
So, we have:
So, we have:
<em>Hence, the sign of the expression is negative</em>
<em></em>
Take for instance;
The expression would be:
-- negative
Answer:
A/B O.5 (you put 0.5 as A and B) but 0.5 is the answer.
Step-by-step explanation:
In expanded form of decimal fractions we will learn how to read and write the decimal numbers. ... (i) 100 + 0.5 + 0.06 + 0.008 (ii) 80 + 1 + 0.02 + 0.005.
Answer:
x = 41.67
Step-by-step explanation:
The above equation, would be simplified or divided into parts;
Therefore, the given equation becomes;
A/x = B/C
Where;
A = (15.2*0.25-48.51/14.7)
B = (13/44-2/11-5/66/2.50)1.2
C = 3.2+0.8(5.5-3.25)
x = unknown variable.
<u>Part A</u>
(15.2*0.25-48.51/14.7) = (15.2*0.25 - 3.3)
A = (3.8 - 3.3)
A = 0.5
<u>Part B</u>
(13/44-2/11-5/66/2.50)1.2 = (0.3 - 0.18 - 0.030) * 1.2
B = 0.09 * 1.2
B = 0.108
<u>Part C</u>
(3.2+0.8(5.5-3.25)
C = 4*(2.25)
C = 9
<em>Substituting the values into the equation, we have;</em>
0.5/x = 0.108/9
<em>Cross-multiplying, we have;</em>
9 * 0.5 = 0.108x
4.5 = 0.108x
x = 4.5/0.108
x = 41.67
Slope intercept form= y=mx+b.
y=9x-9
