The second answer from the top is correct. Your original choice is incorrect because the 7x and the 3 are not both being squared as the statement suggests.

Answer:

\frac{(7x+3)^2}{4(x-1)}

Step-by-step explanation:

The square of the sum of 7 times x and 3 divided by 4 times the difference of x and 1

Convert the verbal statement into an expression

sum of 7 times x  and 3 become 7x+3, for sum we add

for square we put exponent 2, square of the sum (7x+3) becomes (7x+3)^2

differeence of x and 1 is x-1

4 times the difference means we multiply by 4

it becomes 4(x-1)

The square of the sum of 7 times x and 3 divided by 4 times the difference of x and 1

(7x+2)^2 divide by 4(x-1)

\frac{(7x+3)^2}{4(x-1)}

Perpendicular lines will have negative reciprocal slopes. What that means is if u have a slope of 1/2, to find the negative reciprocal, flip the slope and change the sign.......flip 2/1, change the sign -2/1 or just -2. So the negative reciprocal for the slope of 1/2 is -2. 

A. y = 1/5x + 3.....slope here is 1/5, so for a perpendicular line, u r gonna need an equation with the slope of -5.....and that would be : y + 3 = -5(x + 2).

B. Parallel lines will have the same slope. y = 5x - 2...the slope here is 5...so a parallel line will have a slope of 5.

y = mx + b
slope(m) = 5
(8,-2)...x = 8 and y = -2
now we sub, we r looking for b, the y intercept
-2 = 5(8) + b
-2 = 40 + b
-2 - 40 = b
-42 = b

so ur parallel equation is : y = 5x -42

If f (x) = x + 7 and g (x) = StartFraction 1 Over x minus 13 EndFraction, what is the domain of (f circle g) (x)?
Rashid [163]

Answer:

R-{13}

Step-by-step explanation:

We are given that

f(x)=x+7

g(x)=\frac{1}{x-13}

We have to find the domain of fog(x).

fog(x)=f(g(x))

fog(x)=f(\frac{1}{x-13})

fog(x)=\frac{1}{x-13}+7=\frac{1+7x-91}{x-13}=\frac{7x-90}{x-13}

Domain of f(x)=R

Because it is linear function.

Domain of g(x)=R-{13}

Because the g(x) is not defined at x=13

fog(x) is not defined at x=13

Therefore, domain of fog(x)=R-{13}
