Answer:
The answer is (D) ⇒ 2x² - 2 ; domain: all real numbers
Step-by-step explanation:
∵ f(x) = 2x² + x - 3
∵ g(x) = x - 1
∴ (f - g)(x) = 2x² + x - 3 - (x - 1) = 2x² + x - 3 - x + 1
= 2x² - 2
∵ There is no value of x make the function undefined
∴ The domain is all real numbers
Answer:
1. line a and c and parallel. line b is perpendicular with line a and c. 2. line b and c and parallel. line a is perpendicular to lines b and c. 3. y= -3x + 3 4. y=(5/3)x - 9
Step-by-step explanation:
To find parallel and perpendicular, make the slope opposite and find b by plugging in the points. Parallel is the same slope.
it is b
Step-by-step explanation:
b because I said its b now pick b huryy
The answer i belive it's B i'm not 100% sure
Answer:
b = -9.
Step-by-step explanation:
The line passes through (4, 3) and (7, 12). First, we need to find the slope: the rise over the run.
(12 - 3) / (7 - 4) = 9 / 3 = 3.
Now that we have the slope, we can say that m = 3. So, we have an equation of y = 3x + b. To find b, we can use M(4, 3) and say that y = 3 and x = 4.
3 = 3 * 4 + b
b + 12 = 3
b = -9.
Hope this helps!
