Answer:
y = -5/4x - 7
Step-by-step explanation:
First, find the slope:
3 - -7 / -8 - 0 = -5/4
Put it in point slope form:
y + 7 = -5/4(x-0)
y + 7 = -5/4x
y = -5/4x - 7
Answer:
60% of Y is 72
Step-by-step explanation:
25% of Y is 30 so multiply 30 by 4 and you get 120. Multiply 120 by .60 and that leaves you with 72 as your answer.
Answer:
a. 12 - 8x - x² + x³
b. 275 - 375x - 351x² + 240x³ + 112x⁴
c. 30 + 37m - m² - 25m³ - 14m⁴ + 3m⁵
d. 81 + 9x² + x⁴
Step-by-step explanation:
Tabular method is what I hear people call "Partial Products". Alright. All you have to do is look at how many terms are in each factor, break them up separately into columns and rows, then do your multiplication. This is the best example you will get, and just so you know, it is NOT drawn to scale [IMPERFECT]:
d.
9 | -3x | x²
------|-------|-----
9 | 81 | -27x | 9x²
____________________
3x | 27x| -9x² | 3x³
| | |
____________________
x² |9x² | -3x³ | x⁴

Add up all the boldfaced terms inside the box, and you will get the above answer.

Answer:
f^-1(x) = (4x +3)/(1 -x)
Step-by-step explanation:
Solve for y:
f(y) = x
(y -3)/(y +4) = x
y -3 = xy +4x . . . . . . multiply by y+4
y -xy = 4x +3 . . . . . . add 3-xy
y(1 -x) = 4x +3 . . . . . factor out y
y = (4x +3)/(1 -x) . . . divide by the coefficient of y
The inverse function is ...
f^-1(x) = (4x +3)/(1 -x)
