Answer:
Postulate 1a: A plane contains at least three points not all on one line.
Step-by-step explanation:
If we substitute equation (2) into (1) then we have the equivalent equations; y = 5 - x and 5 - x = 9x².
<h3>What is a mathematical equation?</h3>
An equation must contain two sets of variables, the independent variable and the dependent variable separated by the equality sign.
In this case, the original system of equations are; y = 9x² and x + y = 5. It the follows that, if we substitute equation (2) into (1) then we have the equivalent equations; y = 5 - x and 5 - x = 9x².

What are you asking I’m lost
Answer:
0.45.
Step-by-step explanation:
To find the solution to this question, we will first need to determine how many cards are neither Cincinnati Reds and Cleveland Indians. We can do this by:
100 - 22 - 33 = 45. This is the number of cards that are neither the two teams.
To convert this to a decimal, simply divide by 100, giving us:
45 ÷ 100 = 0.45.
