The one with the U shape going up, and the red line is tilting to the left that last picture
The statement on the bottom left is correct. (6 students studied for 20 to 24 hours)
Answer:
6/4 = 1 1/2
1 2/4
12/8
Step-by-step explanation:
Given that the two lines are parallel, we can assume that the two angles given are supplementary (due to them being same side interior angles)
Supplementary angles - when the sum of their degree measure is 180°
8x - 13 + 4x + 1 = 180
12x = 192
x = 16
Answer:
y = - 3x + 5
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, - 4) and (x₂, y₂ ) = (1, 2)
m =
=
= - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, 2), then
2 = - 3 + c ⇒ c = 2 + 3 = 5
y = - 3x + 5 ← equation of line
