Answer:

-2

Step-by-step explanation:

use the rise over run equation: your rise is 8 and your run is -4

your first y is 4 and your second y is -4: 4 - (-4) is 8

your first x is -4 and you second x is 0; -4 - 0 is -4

dividing 8 by -4 will give you -2, which is your slope

If f(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to (fog)(x)?

Vedmedyk [2.9K]

Answer:

3(x² + 1) + 2

Step-by-step explanation:

(f ○ g)(x) = f(g(x))

Substitute x = g(x) into f(x), that is

f(x² + 1) = 3(x² + 1) + 2 ← is the equivalent statement

One car travel 56 miles per hour and another travels 31 miles per hour. If they start from the same place at the same time and t

Vitek1552 [10]

After 3 hours, the faster car will be 75 miles ahead of the slower car.

Step-by-step explanation:

Given,

Speed of first car = 56 miles per hour

Speed of second car = 31 miles per hour

Let,

x be the number of hours.

Distance covered by first car = Speed * time = 56x

Distance covered by second car = 31x

According to given statement;

Difference between distance covered by both cars = 75 miles

Distance of faster car - Distance of slower car = 75 miles

$56x-31x=75\\25x=75$

Dividing both sides by 25

$\frac{25x}{25}=\frac{75}{25}\\x=3$

After 3 hours, the faster car will be 75 miles ahead of the slower car.

Which of the following is the equation of a line parallel to the line y=-x+1 passing through the point (4,1)

Softa [21]

Y=-x+b

plug in x = 4 and y = 1 to find b

1 = -4 + b and we know that if you add 5 and -4 you get 1. So ...

5 = b so if we plug that in

y= -x + 5

which is the same as y + x = 5, So it would be A
