I think the correct answer among the choices listed above is option C. The only true statement is that t<span>he domain of the logarithmic function f(x) = log5x is all positive real numbers. Hope this answers the question. Have a nice day.</span>
Answer:
y = -2x + 8
Step-by-step explanation:
The point slope form of an equation is written as
y = mx + c ...............(i)
Where m is the slope and c is the constant
Now we Know that the equation is
y + 2 = -2(x-5)
and the given points are
m= -2
x = 5
and y= -2
Putting these values in equation (i) to find the value of c
y = mx + c
it becomes
-2 = -2(5) + c
-2 = -10 + c
Adding 10 on both sides
-2 + 10 = -10 + 10 + c
8 = c
or c=8
Now we have the values of m and c
where m= -2 and c = 8
Point slope form of an equation is
y = mx + c
putting the values of m and c to get equation in slope intercept form is
y = (-2)x + 8
or
y = -2x + 8
Other method:
The given point slope form is
y + 2 = -2(x-5)
We have to change it in y= mx + c form
so solving it
y + 2 = -2x + 10
Subtracting 2 from both sides
y + 2 -2 = -2x + 10 -2
y = -2x + 8
which is same is
y=mx + c
so the required equation is
y = -2x + 8
The decimal point separates the places larger than 1 from those that are fractions of 1
Answer:
It is a function
Step-by-step explanation:
The x has only one y and that makes it a function
If the probability of flipping heads is 0.70, the probability of flipping tails is 0.30.
To find probability, you multiply the probability of each factor together:
P = 0.7 * 0.3
P = 0.21 <em>or</em><em> </em>21%
