Answer:
29,100
Step-by-step explanation:
29.1 × 10 = 291
29.1 × 100 = 2,910
29.1 × 1000 = 29,100
9u-9t=18
original no. is 10t+u
reversed no. is 10u+t
so its (10u+t)-(10t+u)=18
which gives 9u-9t=18
Answer:
There are two intersections
Step-by-step explanation:
The number of intersections can be found by calculating the delta of the equation
Δ=b²-4ac
if Δ=0, there is 1 intersection
if Δ>0 there are 2 intersections
if Δ=<0, there are no intersections
where the quadratic equation is in the form ax²+bx+c
Δ=7²-4(2)(6)
=1>0
There are two intersections
