Answer:
C. 5x² - 4
General Formulas and Concepts:
<u>Algebra I</u>
- Composite Functions
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4x² + 1
g(x) = x² - 5
(f + g)(x) is f(x) + g(x)
<u>Step 2: Find (f + g)(x)</u>
- Substitute: (f + g)(x) = 4x² + 1 + x² - 5
- Combine like terms: (f + g)(x) = 5x² - 4
we have that
f(x)=3x-2
g(x)=4x-1
3x-2=4x-1-------------> 4x-3x=-2+1--- > x=-1
find the value of f(x) or g(x) for x=-1
f(x)=3x-2 -------> f(-1)=3*(-1)-2 ------>
f(-1)=-5
the solution is the point (-1,-5)

graphs of the two functions intersect.</span>
Step-by-step explanation:
it's simple:
- 8 tens + 19ones = 9 tens + 9 ones
- 8 tens + 2 ones =7 tens+12 ones
- 7 tens +25 ones = 9 tens + 5 ones
- 70+11=80+1
- 50+13=60+3
- 90+13=100+3
Answer:
216
Step-by-step explanation:
18 which is the base will be multiplied by the height which is 12 giving you
18 x 12 = 216
