Answer:
It could be any of them.
Step-by-step explanation:
First off, It could be said that (2c-d)(2c-d) doesn't belong because it includes two subtractions signs and none of the others do.
Secondly, It could be said that (2c+d)(2c-d) doesn't belong because it includes one subtraction sign and one addition sign and none of the others do.
Thirdly, It could be said that (2c+d)(2c+d) doesn't belong because it includes two addition signs, and none of the others do.
Finally, it could be said that (c+d)(c+d) doesn't belong because it doesn't have a multiplying factor of 2 within the parentheses.
I hope this helps :)
Answer:
g(f(5)) = 6
Step-by-step explanation:
Obtain f(5) from the graph of y = f(x)
Locate x = 5 on the x- axis, go vertically up to meet the graph at (5, 4 )
Now evaluate g(4) from the graph of y = g(x)
Locate x = 4 0n the x- axis, go vertically up to meet the graph at (4, 6 )
Then the value of g(f(5)) = 6
The answer should be D
The reason why is because they are in parentheses so it’s going to be a sum and the two different coefficients are 4 and 7
(first step:
you must remember the following theorem :
Two lines whose slopes are m1 and m2, are perpendicular if and only if m1m2 = -1
(second step
you have one slope given and it is -2 then you substitute in the previous equation
(third step
m1*-2=-1⇒m1=-1/-2⇒m1= 1/2
it means that new slope of the equation is 1/2
(for step
with a given point and a the slope you can build the equation that is perpendicular to a line with slope -2
the equation point- slope is
y-y1=m(x-x1)
with any given point as (2,-5) substitute it in the previous equation
[y-(-5)]= 1/2(x-2)⇒ (y+5) = 1/2x-1/4⇒y-1/2x+5+1/4⇒y-1/2x+21/4 =0
(five step
you must look for the value of x in the following equation
y-1/2x+21/4 =0
where, y = 1/2X-21/4 and this is the equation that represents a line that is perpendicular to a line with slope -2
