Answer:
9.6
Step-by-step explanation:
Step 1:
Find the rate of proportion
We can do 12/10 to find how many minutes it takes her to read 1 page, or 1.2.
Step 2:
Multiply 1.2 by 8 to get 9.6
<em>ALTERNATIVE METHOD:</em>
Divide 10 by 8 to get 1.25. Then divide 12 by 1.25 to get 9.6
Answer:
f(g(-1)) = 22
g(f(-1))=6
Step-by-step explanation:
We are given
We need to find f(g(-1)) and g(f(-1))
Finding f(g(-1))
First we will find f(g(x)) i.e
Now finding f(g(-1)) by putting x=-1
So, f(g(-1)) = 22
Finding g(f(-1))
First we will find g(f(x)) i.e
Now finding g(f(-1)) by putting x=-1
So, g(f(-1))=6
Answer:
a is approximately 16.25, using the pythagorean theorem.
Step-by-step explanation:
a^2+ b ^2 = c^2
The answer is <span>49x2 _ 84x + 36
</span>
(7x - 6)² is the square of the difference. The general formula would be:
(a - b)² = a² - 2ab + b²
In our expression (7x - 6)², a would be 7x and b would be 6:
(7x - 6)² = (7x)² - 2 · 7x · 6 + 6²
= 7² · x² - 84x + 36
= 49x² - 84x + 36
