Alright so I'm gonna set up an inequality for this. Let x be the hours
50 + 9x ≤ 200
9x ≤ 150
x ≤ 16.6
They said that the car cannot be rented for part of an hour so that means we must found it down. the max she can rent it for is 16 hours.
Check: 9*16 + 50 = 194 which is just under her budget
amount after 2 years = 6000(1 + (0.04/12))^24 = 6498.86
x²+3x = 9x - 8
Subtract 9x on both sides
x² - 6x = -8
Add 8 on both sides
x² - 6x + 8 = 0
Now you need to find the factors of 8(numbers that multiply to equal 8) that add or subtract to -6.
Factors of 8: 1, 2, 4, 8
2 and 4 add up to 6, if they are both negative they equal -6.
(x - 2)(x - 4) = 0
x - 2 = 0
x = 2
x - 4 = 0
x = 4
x = 2, x = 4
Answer:
D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 4 and (a, b) = (- 2, 7), thus
y - 7 = - 4(x - (- 2)), that is
y - 7 = - 4(x + 2) → D
