Answer:
6 8/9 , 69/10 , 6.99 , 7.927
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = -2/3 x multiply both sides the first equation by 6
6y = -4x Add 4x to both sides.
6y + 4x = 0
<u>-9y +4x = - 40 </u> Subtract the bottom equation
15y = - 40 Divide by 15
y = -40/15
y = - 2.7
======================
6y = -4x
6*(-2.67) = -4x
-16 = - 4x
x = - 16/-4
x = 4
Answer:
(x + 3, y - 2)
Step-by-step explanation:
we know that
The rule of the transformation T is equal to
T: pre-image → image
T: (x, y) → (x',y')
T: (x, y) → (x - 3, y + 2)
so
x'=x-3 ----> x=x'+3
y'=y+2 ----> y=y'-2
The rule of the inverse of transformation T -1 is equal to
T-1: image → pre-image
T-1: (x', y') → (x,y)
T-1: (x', y') → (x'+3, y'-2)
Step-by-step explanation:
The difference of number p and 2 is at least 5
means
p - 2 ≥ 5
then
p ≥ 7
