Which ordered pairs are in a proportional relationship with (0.2, 0.3)?
A
(1.2, 2.3)
B
(2.7. 4.3)
C
(3.2, 4.8)
D
(3.5, 5.3)
E
(5.2, 7.8)

a² + b²= c²

24² + 7² = c²

c= 25

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
