Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Question
Pls help me solve number 6,7 and 8. Thank you. The other picture is guide for 6 and 7
Transcribed Image Text:Solve for a
(E y)(E x²) – (E x)(E xy)
n(E x²) – (E x)²
(181)(1594. 5) – (118.8)(2427.1)
9(1594. 5) – (118. 8)²
a = 1.1179448241 or 1. 1179|
(INIX 154.6) - (118.0x 44871.1)) : ((9× lv44.5)-(108.9)*) -
Solve for b
n(E xy) – E × E y
n(E x²) – (E x)*
9(2427. 1) – (118.8)(181)
9(1594. 5) – (118. 8)²
b = 1.4388762339 or 1. 4389
