Hello!


This question is an example of function composition.


Given, f(x) = 3x - 5, find f(x - 1). For this problem, we substitute x for (x - 1).


f(x - 1) = 3(x - 1) - 5

f(x - 1) = 3x - 3 - 5

f(x - 1) = 3x - 8


Therefore, the answer is choice D, f(x - 1) = 3x - 8.

Help meeeee doooo thissss
lesya692 [45]

Answer:

B:  x=-5  and x=4

Step-by-step explanation:

f(x)= x^2 + x -20

To find the zeros we replace f(x) with 0

0= x^2 + x -20

now we solve for x

LEts factor x^2 + x -20

sum is +1  and product is -20

5 * (-4)= -20

5 + (-4) = +1

x^2 + 5x - 4x - 20 = 0

(x^2 + 5x)+(- 4x - 20) = 0

x(x+5) -4 (x+5) = 0

(x-4)(x+5)=0

Set each factor =0 and solve for x

x- 4 =0 so x=4

x+5 =0 so x=-5

x=-5  and x=4

Answer:

negative

Step-by-step explanation:

okay so look at the rise and the run of this line (that is given). slope is defined as rise divided by run. the "rise" is the change in y values, while the "run" is the change in x values. the rise in this problem is -4, as shown on the graph. the run is 3, as also shown there. therefore, the slope is -4/3. the type of slope this is is negative slope because the slope is clearly negative.

Jane bought a sofa on sale for $629. This price was 26% less than the original price. What was the original price? ​
Nadya [2.5K]

26% less = 74% of the original

In other word, $289 is 74% of the Original Price

629 = 74% * x

629 = .74*x

629/.74 = x

x = 850

Original price is $850
