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.
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
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:
she got 91 more acres of land
Step-by-step explanation:
all you have to do is see that there was 1,300 and now she owns 1,391 it adds 91 more acres of land hope this helps mark me as brainlist:)
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.
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
