Answer:
The relationship is linear: y -5 = 2 (x+7)
Step-by-step explanation:
While the difference between -7 and -5 / -5 and -3 / -3 and -1 is always 2 teh difference between 5 and 9 / 9 and 13 / 13 and 17 is always 4.
y-5 = -1/2 (x +7)
for x= -7 and y = 5 this is true
for x=-5 and y = 9 this is not true
y + 7 = 1/2 (x-5)
for x= -7 and y = 5 this is not true
y -5 = 2 (x+7)
for x= -7 and y = 5 this is true
for x = -5 and y = 9 this is true
for x = -3 and y = 13 this is true
for x = -1 and y = 17 this is true
Answer:

Step-by-step explanation:
25= r•r•8 ⇔ 25/8 = r²
then

Answer:
$21.76
Step-by-step explanation:
15% of $25.60= $3.84
$25.60-$3.84= $21.76
