Simplify the following
7^1 =
4^0 =
6^-1 =

(I thought 7^1=7, 4^0=1, and 6^-1=0.16 but it is saying 0/1 points so???
Help!

try 6^(-1) = 0.17 or 1/6

Step-by-step explanation:

1/6 in decimal form is 1.66666... which technically should round to 1.7

if 1.7 isn't the right answer try righting it in exact form, 1/6 where there is no estimation

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
