Step-by-step explanation:
plug the coordinate points into the equations and solve for the remaining variable.
b) (2,3) - 5(2) + b(3) = 16
10 + 3b = 16. 3b= 6. b = 2
(0,8) - 5(0) + 2(8) = 16. 0+ 16 = 16. ☆
a) (4,4) assume based on results you meant y squared. (y^2)
(4)^2 = 4k. 16 = 4k. k = 4
(8)^2 = 4(16). 64 = 64. ☆
The rate of the faster car would be 87 kilometers per hour.
The first four terms of the sequence that follows the rule is 2, -1, 5 and -7
<h3>What is an
equation? </h3>
An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
A sequence of numbers follows the rule: multiply the previous number by -2 and add 3. Let a represent the third term, hence if the 4th term is -7:
-7 = -2a + 3
a = 5
Let b represent the second term, hence:
5 = -2b + 3
b = -1
Let c represent the first term, hence:
-1 = -2c + 3
c = 2
The first four terms of the sequence that follows the rule is 2, -1, 5 and -7
