First lets invert the divisor and chane to a multuplication:-
x + 5 2x^2 - 7x - 4
----------------- * --------------------
2x^2 + 3x + 1 3x^2 + 18x + 15
Now we can factor the 3 trinomials:-
x + 5 (2x + 1)(x - 4)
-------------- * ------------------
(2x + 1)(x + 1) 3(x + 5)(x + 1)
Now we simplify because (2x + 1) and (x + 5) are common to top and bottom:-
1 * x - 4
= ------------- ------------
x + 1 3( x + 1)
= x - 4
--------------
3(x + 1^2
Answer:
y intercept (0,490)
I would use (Graphing equation standard form) to identify x and y intercepts. I will Plot the y intercept (0,490) and the x intercept (735,0)
,It will Connect the two intercepts with a straight line
2x + 3y = 1,470
3y = -2x + 1470
y = (-2x + 1470 ) / 3
y = -2/3 * x + 1470/3
y = -2/3 * x + 490
slope is -2/3
y intercept is 490
x intercept (735,0)
Step-by-step explanation:
The function is: f ( x ) = x³ - 2 x² - 68 x - 120
If f ( - 2 ) = 0, we have to divide this equation by: ( x + 2 )
( x³ - 2 x² - 68 x - 120 ) : ( x + 2 ) = x² - 4 x - 60
- x³ - 2 x²
--------------
- 4 x² - 68 x - 120
4 x² + 8 x
---------------------------
- 60 x - 120
60 x + 120
-----------------
0
After that for a function: f ( x ) = x² - 4 x - 60; f ( - 6 ) = 0
( x² - 4 x - 60 ) : ( x + 6 ) = x - 10
-x² - 6 x
-----------------
- 10 x - 60
10 x + 60
-------------
0
Answer:
C ) ( x - 10 ) ( x + 2 ) ( x + 6 )
Answer:
7 X 9 = 63
Step-by-step explanation:
Basically if 7 friends each spent $9 each you can times it to get the answer like 7x9 = 63 because each friend spent 9 each and there is seven so there for all together its 63
The answer would be x = 4 miles.
