Answer: 1.5
Step-by-step explanation:
The equation of a line in slope - intercept form is given as :
y = mx + c , where :
m = slope
c = y - intercept
Given:
2y = 3x - 30
What we need to do is to write it in slope - intercept form, we will make y the subject of formula.
Divide the equation through by 2
2y/2 = 3x/2 - 30/2
y = 3x/2 - 15
comparing with y = mx + c
slope = 3/2 = 1.5
Answer:
5 days
Step-by-step explanation:
The question above is modeled by the equation :
150 − 8x = 170 − 12x.
After how many days will both have ye same amount :
Number of days = x
Collect like terms
-8x + 12x = 170 - 150
4x = 20
x = 20/4
x = 5 days
The boys will have the same amount in their account after 5 days.
