Remember
if ab=0, then assume that a and b equal 0
factor out common term
comon term in 6x^2 and 15x is 3x
3x(2x)+3x(5)=0
3x(2x+5)=0
set each to zero
3x=0
x=0
2x+5=0
2x=-5
x=-5/2
x=-5/2 and 0
Answer:
Step-by-step explanation:
for y intercept
we calculate f(0) and the value is y intercept
for the slope we have 2 points (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
Answer:
The first equation
Step-by-step explanation:
Answer:
The answer is 45.72
Step-by-step explanation:
If 1 yard = 2.54 centimeters, you multiply each side by 18.
1*18=18
2.54*18=45.72.
18 yards=45.72 centimeters.
