Answer:
4th option
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (2, 12) and (x₂, y₂ ) = (6, 6) ← 2 points on the line
m = = = -
the line crosses the y- axis at (0, 15 ) ⇒ c = 15
y = - x + 15 ← approximate equation of line of best fit
1). 8 x 5x - 8 x 3y
40x - 24y
you have to multiply the eight inside the parentheses
Answer:
153.5
Step-by-step explanation:
Given 25% of 614
That’s 25% /100% x 614
0.25 x 614
153.5
9514 1404 393
Answer:
(x, y, z) = (x, x+2, 3x+1)
Step-by-step explanation:
We can add twice the second equation to the first to get ...
[eq4] -3x +0y +z = 1
Adding the first and second equations gives ...
[eq5] -x +y +0z = 2
Solving [eq4] for z gives ...
z = 3x +1
Solving [eq5] for y gives ...
y = x +2
Then the solution triple is (x, y, z) = (x, x+2, 3x+1).
