Answer:
We conclude that the ordered pair (2, 1) is a solution.
Step-by-step explanation:
Given the equation

Check for point (2, 1)
substituting the point (2, 1) in the equation to check whether the ordered point satisfies the equation or not.

plug in x = 2 and y = 1
1 = -2(2)+5
1 = -4+5
1 = 1
R.H.S = L.H.S
TRUE
Therefore, the given ordered pairs satisifes the equation.
Hence, we conclude that the ordered pair (2, 1) is a solution.
Our brains judge the speed of objects passing by us through the time taken for them to cross our field of view. Those taking a long time could either be nearby and travelling slowly or faster and further away. And in the case of planes, our brains know that the second interpretation is the right one.
Answer:
7,12,17,22,27
Step-by-step explanation:
You just plug in 1,2,3,4,5 as n and add your values
so 7+5(1-1)=7
7+5(2-1)= 12 and so on
Answer:
D
Step-by-step explanation:
One is 160, and the other is 52. To find the answer, we add.
52+160=212, which is D.
Ergo, D is the correct answer.
42 = (3•t) + (30)
42=12 + 30
42=42
T=4
