Whats the sum for 5(−3.4k−7)+(3k+21)

-14k-14

Step-by-step explanation:

5(−3.4k−7)+(3k+21) this is the same as:

(5*-3,4)k-(5*7)+3k+21

-17k-35+3k+21

Grouping terms of k:

(-17+3)k-35+21

-14k-14

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
