Answer: y = 30x + 50
Step-by-step explanation:
let y be the distance traveled (in meters) after x minutes.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (260 - 110)/(7 - 2)
m = 150/5 = 30
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 7, y = 260 and m = 30 into y = mx + c. It becomes
260 = 30 × 7 + c = 210 + c
c = 260 - 210
c = 50
The linear model becomes
y = 30x + 50
Part A: Barry has his own job. Barry saves his earned money and doesn't spend it. He cuts down on buying things he doesn't need. After a while, Barry will have enough money saved to go on vacation with his family.
Part B: Barry has a job, but he buys all kinds of thing with his money. He saves no money and wastes it on things he doesn't need. he gives his money aws=ay to his friends. Barry will not have money for a family vacation.
Answer:
g = 12
Step-by-step explanation:
g + 7 - 4 = 15
Combine like terms
g +3 = 15
Subtract 3 from each side to isolate g
g+3-3 = 15-3
g = 12
12 is div. by 3 but not 9
