Answer:
7x (x + 1 ) ( x + 3 )
Step-by-step explanation:
7x³ +28x² +21x
7x ( x² + 4x + 3 )
7x [ x² + 1x + 3x + 3 ]
7x [ x ( x + 1 ) + 3 ( x + 1 ) ]
7x (x + 1 ) ( x + 3 )
Answer:
The equation of a line through (5 -3) that is parallel to y = 1/2 x+3 is
y = - 2 x + 7
Step-by-step explanation:
Let us assume the slope of the line whose equation we need to find is m 1.
The line parallel to the needed line is: y=1/2x+3
Comparing it with the general form: y = m x + C
we get m 2 = 1/2
Now, as Line 1 is Perpendicular to Line 2.
⇒ m 1 x m 2 = -1
⇒ m 1 x ( 1/2) = -1
⇒ m 1 = - 2
Also, the point son the line 1 is given as: (x,y) = (5,-3)
Put the value of point and Slope in y = m x + C to find the value of Y- INTERCEPT.
we get: -3 = (-2) (5) + C
or, C = -3 + 10 = 7
⇒ C = 7
The general line equation is given as: y = m x + C
Substituting the values of C and m, we get:
y = - 2 x + 7
Hence, the equation of a line through 5 -3 that is parallel to y = 1/2 x+3 is
y = - 2 x + 7
15 is the answer because 8-5 is 3 and 3 and 4 is 12 so 12 plus 3 is 15
The answer is 376$ because 47 x 8.00 = 376$
