1. The population of a city increases by 4000 people each year. In 2025, the population is projected to be 450,000 people. What is an equation that gives the city's population p (in thousands of people) x years after 2010?
A) p=4x+450
B)p-450=4(x-5)
C)p-15=4(x-450)
D) p=4x+15
i keep getting a different answer. somebody pls help me!?? thanks
actually 5 is B not C
1. C
2. C
3. D
4. B
5. B
1. y-6 = -12(x + 4)
C. y = -12x - 42
2. y + 4 = -5(x - 3)
C. (3, -4)
3. (6, -3) and (-4, -9)
D. y + 3 = 3/5(x - 6)
4. The population of a city increases by 4,000...
B. p - 450 = 4(x - 15)
5. y - 3 = -3/2(x + 4)
B. The graph in which the line passes through points: (2, -6) (-6, 6)
Yup. It's
1.C
2.C
3.D
4.B
5.B
I put C instead of B for 5 as everyone said, and it was wrong. You don't have to believe me, but you'll see for yourself.
kezie is right 5 is b not c
i got a 4/5 with #5 being C
the correct answer is B
5 is b
You have a point (15,450) and a slope (4), so the line should be
p-450 = 4(x-15)
I'd say (B) with a typo
Steve, there was a typo. :)
The answers for Honors Algebra 1A. (Point Slope Form Quick Check)
1.} C. y=-12x-42
2.} C. (3,-4)
3.} D. y+3=3/5(x-6)
4.} B. p-450=4(x-5)
5.} C. y+2=2(x+1)
Just took the test: 100%
