10*5+10*5*1 I think this is the right way
Answer:
slope = -3/4
using the formula
y -y1 = m(x -x1)
y -1 = -3/4(x -(-8))
y -1 = -3/4(x +8)
cross multiply
4(y -1) = -3(x +8)
4y -4 = -3x -24
4y = -3x -24 +4
4y = -3x -20
divide both sides by 4
y = -3/4 x -5 (equation of the line)
Answer:
B -o.60
Step-by-step explanation:
34 - 40 = -6. -6 divide by 10 = -3/5 or - 0.6. So answer is B
10 + 5d = 13.50
5d = 13.50 - 10
5d = 3.50
d = 3.50/5
d = 0.7.......so one large drink (d) cost 70 cents
The solutions are where the quadratic is equal to 0, or when the quadratic crosses the x axis.
Where the quadratic crosses the x axis are the solutions:
6) x = –5, x = –6
7) x = 0, x = 1
8) x = –6, x = 1
9) x = –4, x = –3
