This problem can be solved easily. The equation states that
y is a function of x. Since this is the case, then we can get the initial value
of the function when x = 0. Therefore by substitution:
y = - 2 x -5
y = - 2 (0) – 5
y = -5 (ANSWER)
Answer:
for second question
first length is 9cm
Area=l*b
= 9cm *9cm
=81<em><u>cm</u></em>
then, For semicircle
radius is 9 cm
area= 1/2*9cm
now , area of two semi circle = 2*1/2*9
= 9 cm
now area of shaded = 81-9
=72
Answer:
Choice C is the answer.
Step-by-step explanation:
We have given two functions.
f(x) = 2x² - 5x -3 and g(x) = 2x² + x
We have to find (f/g) (x) .
The formula to find (f/g) (x) is :
(f/g) (x) = f(x) / g(x)
Simplifying f(x) and g(x) , we have
f(x) = 2x²-6x+x-3
f(x) = 2x(x-3)+1(x-3)
f(x) = (2x+1)(x-3)
g(x) = x(2x+1)
Putting above values in formula , we have
(f/g)(x) = (2x+1)(x-3) / x(2x+1)
(f/g)(x) = x-3 / x
Denominator must not be zero.
(f/g)(x) = x-3 / x , x ≠0
Answer:
-1
Step-by-step explanation:
divide both sides by 7 and you will get (n+4)=3
then subtract 4 on both sides and get n is equal to -1
