F(x)2x²+1and g(x)=x²-7find (f+g)(x)

3x² - 6

Step-by-step explanation:

note that (f + g)(x) = f(x) + g(x), thus

f(x) + g(x)

= 2x² + 1 + x² - 7 ← collect like terms

= 3x² - 6

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
