The y-intercept represents the initial girth of the tree. Assuming that the X-axis represents time in this scenario (as it usually does) the y-axis, therefore, represents the girth of the tree. The y-intercept is located where X = 0. So if no time has passed then this must be the first measurement of the girth of the tree.
Alright. So We Need To Take A Look At The Answer Choices. The Sum Of Two Rational Numbers Is Always Rational. This Is True. You Cant Add Bad With Bad And Get Good. So You Will Always Get Rational Numbers, So It Is Not A.
Lets Look At B. <span>The product of a nonzero rational number and an irrational number is always irrational. This is True. Pi Times Any Number Is Irrational. If You Have A Repeating Decimal,You Can't Change It To A Whole Number.
Lets Look At C. </span><span>The product of two rational numbers is always rational. This Is True. Any Rational Numbers Multiplied Will Always Be Rational. 3.5 * 4 = 14. this Is Still Rational, So Not C.
Lets Look At D. </span><span>The sum of two irrational numbers is always rational.This Is Not True. If You Do: Pi + Pi, This Will Not Be Rational. So, It Is D.
So, Having Looked At All The Choices, The Answer Is D.

Answer:
Subtraction property of equality
Step-by-step explanation:
Given the equation;
2x + (x+5) = 41
open the parenthesis;
2x+x + 5 = 41 (Associative property)
3x+5 = 41
Subtract 5 from both sides
3x + 5 = 41
3x + 5- 5 = 41 - 5 (Subtraction property of equality)
3x = 36
Divide both sides by 3;
3x/3 = 36/3
x = 12 (Division property of equality)
Hence the required property is Subtraction property of equality
Answer:
6:8 compares the number of tiger shark teeth to sand shark teeth.
Step-by-step explanation:
Ratios, in mathematics, is a way to compare two or more numbers in relation to their sizes. According to the question, Christian collected 18 different shark teeth. He found out that the tiger shark teeth were 6, sand shark teeth were 8, hence the remaining 4 shark teeth would be for bull shark.
In order to compare the number/size of the different shark teeth to one another, we use ratios. Hence, if we say 6:8, it means that the proportion of the tiger shark teeth to the sand shark teeth is 6 to 8. This also means that the tiger shark teeth is 6/8 of the sand shark teeth.
Answer:
a = 36°
Step-by-step explanation:
a + 54° = 90°
a = 90° - 54°
a = 36°
