Algebra 1 Quiz Online Tutoring - Online Tutors Definition: - In arithmetic we use numbers but in algebra we utilize the letters and sign to represent a mathematical problem. For example: - Sum of 9 pencils and 7 books is $ 200, we can represent this in algebraic equation as 9 x + 7 y = 200 where x = price of one pencil y = price of one book. Lets work for few Algebra 1 quiz: Quiz 1: Write the value of 6^3. Solution:- 6 ^ 3 = 6 * 6 * 6 = 216 Therefore, the value of 6^3 =216. Quiz 2: - In which quadrant (3, -1) lie. Solution: - (x, y) is a coordinate where x is the value of abscissa and y is the value of ordinate. So coordinate = 3 and abscissa = -1 for the point (3, -1) Hence for x = 3 we will move to the right, the positive x axis and For y = - 1 we go down, the negative y axis. Hence (3, -1) lie on the 4th quadrant. Quiz 3: - Find the value of a for the following linear equation: 5 a + 10 = 15 Solution: - 5a+10=15 5 a= 15 10 5 a= 5 a = 5 / 5 a =1 Therefore the value of a= 1 Quiz 4: - Find the value of the following algebraic expression for k = 2 2k+5 Solution: -We need to substitute the value k = 2 in the given expression 2k+5=2(2)+5=4+5=9
