Answer:

0

Step-by-step explanation:

Subtraction of functions has the property:

  • (f−g)(1) = f(1) - g(1)

f={(−4,−1),(1,1),(−3,−2),(−5,2)}  has (1,1) means that f maps 1 to 1, therefore f(1) = 1

g={(1,1),(2,−3),(3,−1)}  has (1,1), means that g maps 1 to 1, therefore g(1)=1

As a Result, since (f−g)(1) = f(1) - g(1), we have (f−g)(1) = 1-1=0

Two employees are filling crates. One fills
mina [271]
Calculate both of those per hour:
2/3 crate / hour
1.25 crates / 2 hours = 5/8 crates / hour

2/3 + 5/8 = 16/24 + 15/24 = 31/24 per hour =

124 / 24 crates in 4 hours = 5 (4/24) crates =

5 (1/6) crates per 4 hours

Question 3 of 21

The equation of the red graph, g(x) is g(x) = |x| - 5

<h3>How to determine the equation of the red graph, g(x)?</h3>

The graph that completes the question is added as an attachment

The function f(x) is given s:

f(x) = |x|

From the attached graph, we can see that the function f(x) is shifted 5 units down to get to g(x).

This means that:

g(x) = f(x) - 5

Substitute f(x) = |x|

g(x) = |x| - 5

Hence, the equation of the red graph, g(x) is g(x) = |x| - 5

How do you factor 7v2-47v+30
Semmy [17]
7v² - 47v + 30

7v² - 5v - 42v + 30       split the second term into two terms.

v(7v - 5) - 6(7v - 5)      factor out common terms in the first two terms, then the last two terms.

(7v - 5)(v - 6)      << is your answer

hope this helps, God bless!
