QUESTION 4
vesna_86 [32]

Answer:

f(3) =-8

Step-by-step explanation:

Given

f(x) = 2x + 5; x

f(x) =-3x + 1; x >1

Required

Determine f(3)

f(3) implies that x = 3.

We make use of

f(x) =-3x + 1

Because x >1 (i.e. 3 > 1)

Substitute 3 for x in f(x) =-3x + 1

f(3) =-3*3 + 1

f(3) =-9 + 1

f(3) =-8

3. What is the slope of the line that contains the
dlinn [17]

Answer:

I think the answer would be -1/2 or D.

Step-by-step explanation:

Use this formula for calculating slope : y2-y1 / x2 - x1                                                            

1. label the pairs, 1 and 2

(-6, 1)  - ( x1, y1 )          or        (4,-4) - (x1, y1)

(4,-4) - ( x2, y2)                      (-6,1) - (x2, y2)  

(the order does not matter)

2. Than plug in your numbers

y2-y1 / x2 -x1                 y2-y1 / x2 -x1

-4 - 1 / 4 - (-6)        or        1 - (-4) / -6 - 4

= -5/10 or -1/2               = - 5/-10 or -1/2

im only in eight grade so i did my best explaining , and this hope it helps :)
