Answer:
option B and option D
0 and 2
Step-by-step explanation:
Given in the question two functions
f(x) = x² - 4x + 3
g(x) = -x² + 3
f(x) = g(x)
x² - 4x + 3 = - x² + 3
Rearrange the like terms, x terms to the left and constant term to the right.
x²+ x² - 4x = 3 - 3
2x² - 4x = 0
Divide by two
2x²/2 - 4x/2 = 0/2
x² - 2x = 0
Take x as a common term
x(x-2) = 0
so
x = 0
or
(x-2) = 0
x = 2
Answer:
Step-by-step explanation:
We can simplify the expressio using the product rule. The exponents will add up when multiplied with each other:
The answer is B
Answer: x= -2
Step-by-step explanation: Remove parentheses. Move terms. Collect the like terms. Calculate the sum. Change the signs on both sides of the equation and you should get x= -2.
Answer:
14/19
Step-by-step explanation:
Note that there are two " - " signs here. Thus, the end result will be " + "
We move from left to right, obtaining first 10/19 divided by (5/7):
10
----- ÷ (5/7)
19
To divide by (5/7), invert (5/7) and then multiply. We get:
10 7 2(7)
----- * ----- = ------- = 14/19
19 5 19
