Answer: $3.50 per week
Total money needed: $32
Money saved already: $18
$32 - $18 = $14
Money left to save: $14
-
Money left to save: $14
Time left to save: 4 weeks
$14 / 4 = $3.50 per week
Have a nice day!

Firstly expand (x - 3)(ax^2 + bx + c):
ax^3 + bx^2 + cx - 3ax^2 - 3bx - 3c
Now rearrange it so that it's in the form ax^3 + bx^2 + cx + d:
ax^3 + (b-3a)x^2 + (c-3b)x - 3c
Now we can compare both equations:
ax^3 + (b-3a)x^2 + (c-3b)x - 3c = 2x^3 - x^2 - 19x + 12
We get:
(1) a = 2
(2) b - 3a = -1
(3) c - 3b = -19
(4) -3c = 12
If we substitute (1) into (2) we get:
b - 3*2 = -1
b - 6 = -1
b = 5
Now if we solve (4) we get:
-3c = 12
c = -4
Therefor a = 2, b = 5 and c = -4
Answer:
x/(-5/8)
Step-by-step explanation:
haha lol I was looking for the answer too, but I solved it! Here it is:
Answer:
The slope of line s is b/a. Rotate line s 90° clockwise about the origin to get line t. The labeled points on line s map to (0, a) and (b, 0) on line t. The slope of line t is -a/b. The slopes of the lines are opposite reciprocals because the product of the slopes is -1.
Answer:
x = 55
Step-by-step explanation:
x + (2x+15) = 180
3x + 15 = 180
3x = 165
x = 55
