Answer:
y = 1/2x + 0.5
or
y = 1/2x + 1/2
Step-by-step explanation:
y = mx + b
b is y-intercept:
when x = 0, y = 0.5 (when the line cross the vertical (y) axis of the graph)
the point is (0, 0.5) so b = 0.5
m is slope:
slope = rise / run
rise = 1
run = 2
for every 2 x values, y increase by 1
slope (m) = 1/2
In solving equations, each must have vales of x and y. X is any number and Y is the output of any number. If you substitute x for a number, you can solve the equation for y.
Answer:
Option C - $26.44
Step-by-step explanation:
To find the closing proce on Wednesday
Company XYZ is $ 25.69 on Thursday
Company XYZ is - $0.75 on Wednesday
This means the calculation should be as following,
25.69 + 0.75 = 26.44$ the closing price for Wednesday
we are given
system of equations
First equation is

Second equation is

now, we can find augmented matrix

now, we can change it into reduced row echelon form
step-1: multiply the 1st row by 1/3

step-2:add -3 times the 1st row to the 2nd row

step-3:multiply the 2nd row by 1/4

step-4: add 2/3 times the 2nd row to the 1st row

so, we get

Answer is (5,-8)
