Answer:
-1/2
Step-by-step explanation:
y = -1/2x + 1/4 is in slope y-intercept form : y = mx + b
m is slope
Slope = -1/2
The equation for point slope form is written as :
y - y1 =m(x-x1)
M is the slope which is given as -37
The given point would be X1 and y1, where X1 is 5 and y1 is 8.
The equation becomes:
y - 8 = -37(x -5)
Answer:
3 and 2
Step-by-step explanation:
The ratio of the 2 numbers = 3 : 2 = 3x : 2x ( x is a multiple )
When 5 is subtracted from both , that is
3x - 5 : 2x - 5 = 2 : 3
Expressing the ratio in fractional form
=
( cross- multiply )
3(3x - 5) = 2(2x - 5) ← distribute both sides
9x - 15 = 4x - 10 ( subtract 4x from both sides )
5x - 15 = - 10 ( add 15 to both sides )
5x = 5 ( divide both sides by 5 )
x = 1
Thus the 2 numbers are
3x = 3(1) = 3 and 2x = 2(1) = 2
Answer:
2⅙ miles per day
Step-by-step explanation:
Miles : Days
39/4 = 9¾ : 4½ = 9/2
X : 1
39/4 ÷ 9/2 = X/1
39/4 × 2/9 = X
13/6 = X
X = 2⅙
