The decimal is 0.4what does 10x equal

0.4 × 10 ≈ 4.0

the reason is, normally if any decimal no. is multiplied by 10 , the decimal point will move one step towards the right

well this is how i was taught in schools

i hope the ans is right

hope this hepls :)

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
