Answer:y=2x+1
Step-by-step explanation:
y

y
1=
m(

.
Slope-intercept form:
y
=
2
x
+
1
For this case we have the following system of equations:
5x + 3y = 17
-8x - 3y = 9
The solution to this system can be written in matrix form as:
Ax = b
Where, A is a matrix that is given by:
A = [5 3; -8 -3]
The determinant of this matrix 2 * 2 is given by:
lAl = (5) * (- 3) - (3) * (- 8)
lAl = -15 - (-24)
lAl = -15 + 24
lAl = 9
Answer:
The determinant for solving this linear system is:
lAl = 9
Answer:
ok so I am not that smart but I want to try to help do this is my best. 595
Step-by-step explanation:
I did my answer on a calculator and pretty much I did 195 plus 400 (btw I got 195 by adding numbers) and then got 595. Like I said not 100% sure but this is the best I got
Answer:
y = 1/2x -1
Step-by-step explanation:
to find the y-intercept you find where the line crosses the y axis
for the slope you need to use the equation
change of y2 - change of y1
change of x2 - change of x1
Length x width is the formula.
so 18 x 18 for 7.
22 x 24 for 8.
and 8 would probably be 5 x 5 to equal 20. so the length and width would be 5 and 5 because 20 is the area
