Do you see that when we change
f(x) = 7x - 5
to
f(2) = 7(2) - 5
we are simply saying to substitute in 2 for x? Well that is what we are doing:
f(2) = 7(2) - 5
f(2) = 14 - 5
f(2) = 9
Now we find g(4) the same way:
g(x) = 4(x)
g(4) = 4(4)
g(4) = 16
Now we find the difference of the two functions:
f(2) - g(4)
9 - 16
-7
So, the answer is B.
Nah that aint gonna work for 5 points?? gotta give me more
Hello there ☺️,
There will be two answers to this question. They are:-
<h3>Method (i) </h3>
The exact √28 will be <u>5.2915026221291</u><u>.</u>
<h3>Method (ii)</h3>
Factor 28 to 2² x 7. Rewrite the square root of the product √2² x 7 as the product of square roots √2²√7. Then take the square root of 2².
→ <u>2√7</u>
This is also equal to 5.2915026221291.
Therefore, you can write the answer as <u>2√7</u> or <u>5.2915026221291</u>.

Answer:
$71766
Step-by-step explanation:
Cash price = 897060
10% deposit = 89706
Total 36 monthly payments = 24420 × 36 = 879120
monthly payment + deposit
879120 + 89706 = 968826
968826 - 897070
= 71766
