What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the two linear equations are x + 2y = 14 and y = 3x − 14. Equations can be solved as below,
x + 2y = 14
y = 3x − 14
Substitute the value of y in the first equation,
x + 2y = 14
x + 2 ( 3x - 14 ) = 14
x + 6x - 28 = 14
7x = 42
x = 6
The value of y will be calculated as:-
y = 3x - 14
y = ( 3 x 6 ) - 14
y = 18 - 14
y = 4

Complete the table below for the function y = -3x+7
Answers
Answer:
(x,y)--> (2,1), (4, -5), (7, -14), (9, -20), (11, -26)
Step-by-step explanation:
y = -3x + 7
substituting x-values in y= -3x + 7
x = 2
y= -3 × 2 + 7
= -6 + 7
= 1
x=4
y= -3 × 4 + 7
= -12 + 7
= -5
x=7
y= -3 × 7 + 7
= -21 + 7
= -14
x=9
y= -3 × 9 + 7
= -27 + 7
= -20
x=11
y= -3 × 11 + 7
= -33 + 7
= -26

Jane's situation is the one which represents a porportional relationship.
Step-by-step explanation:
To verify the proportionality betwen a ratio you have to divide all the ratios and all them have to get the same constant factor.
So, if you divide the matt's ratios you aren't gonna find the same constant factor
12/1=12
20/2=10
31/2=15,5
But if you try with Jane's ones:
12/1=12
24/2=12
36/3=12
This 12 is the known constant factor, which show us that these ratios are proportional.
