Answer:
see explanation
Step-by-step explanation:
Given x and y are in proportion then the equation relating them is
y = kx ← k is the constant of proportion
To find k use an ordered pair from the table
Using (2, 10 ), then
10 = 2k ( divide both sides by 2 )
5 = k , thus
y = 5x ← relationship between x and y
Answer:
20, 22, 28, 50
Step-by-step explanation:
The length and width could be:
1, 1, 24, 24
2, 2, 12, 12
3, 3, 8, 8
4, 4, 6, 6
1+1+24+24= 50
2+2+12+12= 28
3+3+8+8= 22
4+4+6+6= 20
Answer:
x=5
Step-by-step explanation:
(5x+2)/3 = 9
Multiply each side by 3
(5x+2)/3 *3 = 9*3
5x+2 = 27
Subtract 2 from each side
5x+2-2 = 27-2
5x = 25
Divide by 5
5x/5 = 25/5
x =
Answer:
<em>y = - x - 10 </em>
Step-by-step explanation:
y - (- 3) = - (x + 7)
<em>y = - x - 10</em>
