Answer:

Step-by-step explanation:
Multiply those together and combine like terms. Then make sure you order the terms in descending powers.
Answer:
X = 9, -1
Step-by-step explanation:
1, Factor it
(x-9) (x+1) = 0
2. Both of a factor will = 0
x-9 = 0
x+1=0
3. Solve
x=9
x=1
Answer:
y = -3x +2
Step-by-step explanation:
If you divide the equation for the given line by 2, it will be in slope-intercept form:
y = (1/3)x +7
This tells you its slope is 1/3. The slope of the perpendicular line is the negative reciprocal of this: -1/(1/3) = -3. The point-slope form of the equation for the perpendicular line can be written as ...
y = m(x -h) +k . . . . . line with slope m through point (h, k)
Your line is ...
y = -3(x -(-2)) +8
y = -3x +2
Answer:
9.268
Step-by-step explanation:
Answer:
If you look at the "Standard Form" column, you can take any number from an upper row and divide it by 4 to get the number in the row below it.
For example: You can take 256 and divide it by 4, and that will give you 64. Like wise, if you take 64 and divide it by 4 you will get 16.
This tells us that every time you add 4 to the equation, your answer will keep increasing 4 times.
