A factor is a group of 2 or more numbers that can be multiplied to make a greater number.
The factors for 400 include:
1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200
When paired together:
(1, 400), (2, 200), (4, 100), (5, 80), (8, 50), (10,40), (16, 25), (20,20)
Prime factors:
1, 2, 5
Answer:
The equation of the line that is perpendicular to the line that passes through the point (-4, 2) is y = -9·x/5 + 18
Step-by-step explanation:
The coordinates of the point of intersection of the two lines = (5, 9)
The coordinates of a point on one of the two lines, line 1 = (-4, 4)
The slope of a line perpendicular to another line with slope, m = -1/m
Therefore, we have;
The slope, m₁, of the line 1 with the known point = (9 - 4)/(5 - (-4)) = 5/9
Therefore, the slope, m₂, of the line 2 perpendicular to the line that passes through the point (-4, 4) = -9/5
The equation of the line 2 is given as follows;
y - 9 = -9/5×(x - 5)
y - 9 = -9·x/5 + 9
y = -9·x/5 + 9 + 9
y = -9·x/5 + 18
Therefore, the equation of the line that is perpendicular to the line that passes through the point (-4, 2) is y = -9·x/5 + 18.
When x is 4 the diagonal line is on the first line above the 4 so that would be y=1
Answer:
0.75
Step-by-step explanation:
3 x 5 = 15 because the opposite of dividing is multiplying
