Answer: 4 and 7.5 you multiply them
Step-by-step explanation:
First, we need to understand the speed formula:
The time used = distance ÷ rate
In this case, the time needed would be:
5 1/5 ÷ 2 1/6
= (5×5+1)/5 ÷ (2×6+1)/6
=26/5 ÷ 13/6
When there is division in an equaiton, we can swap the nominator and denominator of the fraction amd change it to multiplication:
=26/5 × 6/13
= (13 x 2)/5 x 6/(13 x 1)
Factorize 26 and 13,we get:
=2/5 x 6/1
= 12/5 ft or 2.4 ft
Therefore the answer is 12/5ft or 2.4ft.
Hope it helps!
X intercepts are where y=0
0=x^2+1x-42
0=(x-6)(x+7)
set to zero
x-6=0
x=6
x+7=0
x=-7
x intercepts are (-7,0) and (6,0)
y intercept is where x=0
y=0^2+0-42
y=-42
y intercept is (0,-42)
x intercepts at (-7,0) and (6,0)
y intercept at (0,-42)
