Answer:
b. 10a³ - 11a - 3
Step-by-step explanation:
1. Expand 3(a³ - 2a - 5)
= 3a³ - 6a - 15
2. Add 7a³ - 5a + 12 and 3a³ - 6a - 15
7a³ + 3a³ = 10a³
-5a + -6a = -11a
12 + -15 = -3
3. Answer: b. 10a³ - 11a - 3

Step-by-step explanation:
is this correct?
a * b = -70
a + b = -9......a = -9 - b
b(-9 - b) = -70
-b^2 - 9b + 70 = 0
(-b + 5)(b + 14) = 0
-b + 5 = 0
5 = b
b + 14 = 0
b = -14
ur numbers are -14 and 5
-14 * 5 = -70
-14 + 5 = -9
If she would have waited a day she would have saved D) $64.43 more. This is because the original sale price comes to $322.15 and then we find the answer by taking this number and multiplying it by the additional sale and get $64.43.

Answer:
the correct choice is marked
Step-by-step explanation:
The line has a rise of 2 for a run of 1, so a slope of 2. The line crosses the y-axis at y=-2, so the y-intercept is -2. The slope-intercept equation for the line is ...
y = mx + b . . . . . . for slope m and y-intercept b
y = 2x -2
