F(x) = x − 7 and g(x) = x2 . Find f(g(−1)).
1st let's find g(-1) → g(- 1) = (-1)² = 1
Now let's find f(1) →1 - 7 = -6
Answer:
22.
Step-by-step explanation:
The work is in the photo I attached, I think.
Answer:
x = 46
Step-by-step explanation:
Here, we want to get the value of the angle marked x
From the diagram given , the two angles that are other than x can be gotten from the value of their supplements
Angles on a straight line are supplementary as they add up to 180
Thus, mathematically;
(180-130) + (180-96) + x = 180
50 + 84 + x = 180
x = 180-50-84 = 46
Answer:
Coordinates of X is (7/2,9/2)
Coordinates of C is (6,7)
Explanation:
x is the midpint of DB and AC
coordinates of X = ( (5+2)/2 ,(6+3)/2)
= (7/2,9/2)
Coordinates of X is (7/2,9/2)
Let (a,b) be the coordinates of C.
Then,
coordinates of x = ((a+1)/2, (b+2)/2)
(7/2,9/2) = ((a+1)/2, (b+2)/2)
Hence,
7/2=(a+1)/2
7=a+1
a = 6
9/2 =(b+2)/2
9 =b+2
b =7
Coordinates of C is (6,7)
