<span>f(x) = x^2 + 1, find f(a + 1)
so
</span> f(a + 1) = (a+1)^2 +1
f(a + 1) = a^2 + 2a + 1 + 1
f(a + 1) = a^2 + 2a + 2
Answer:
45.8 degrees
Step-by-step explanation:
We know that the temp before take off is 57.9
We also know the temp decreases every 1,000 feet so
if we are 11,000 feet in the air and divide that 11000/1000=11
We know that the temp drops 11 times
11x1.1=12.1
57.9-12.1=45.8 degrees
Answer: See below
Step-by-step explanation:
Isolate x for x-2y+2z=9
3x=9+2y
....(1)
Substitute (1) into the 2nd equation
7y=-3
y=-3/7
Substitute y=-3/7
Isolate z by substituting it
For x =9+2y/3 substitute z=59/21 and y=-3/7
Answer:
B
Step-by-step explanation:
Given that the two lines are parallel, we can assume that the two angles given are supplementary (due to them being same side interior angles)
Supplementary angles - when the sum of their degree measure is 180°
8x - 13 + 4x + 1 = 180
12x = 192
x = 16
