The answer is A.
From looking at the A graph, you must plug in the x variable into<span> y = -2x + 4.
y = -2(0) + 4 = 4
y = -2(1) + 4 = 2
y = -2(2) + 4 = 0</span>
Subtract 7.8 points by 4.8 and you get 3.4 !!
Answer:
The equation is 
.
Step-by-step explanation:
Let 
represent the number of laps Jay run, and 
the number of minutes it takes him to run those laps.
We know that it it takes Jay 25 minutes to run 10 laps; therefore, the number of laps jay runs per minute is:
So, if Jay runs for minutes, the number of laps he will run be:
Answer:
86 is the score that Maurice must get to average his score to 80
Answer:
1. ∀ y ∈ Z such that ∃ x ∈ Z, ¬R (x + y)
2. ∃ x ∈ Z, ∀ y ∈ Z such that ¬R(x + y)
Step-by-step explanation:
If we negate a quantified statement, first we negate all the quantifiers in the statement from left to right, ( keeping the same order ) then we negative the statement,
Here, the given statement,
1. ∃y ∈Z such that ∀x ∈Z, R (x + y)
By the above definition,
Negation of this statement is ∀ y ∈ Z such that ∃ x ∈ Z, ¬R (x + y),
2. Similarly,
The negation of statement ∀x ∈Z, ∃y∈Z such that R(x + y),
∃ x ∈ Z, ∀ y ∈ Z such that ¬R(x + y)
