Answer:
The value of y when x = 90
y = 22.5
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
The value of y is directly proportional to the value of x.
Y∝ X
y = k x
If y = 45 when x = 180
45 = k ( 180)
<u><em>Step(ii):</em></u>-
The value of y when x = 90
y = 0.25 × 90 = 22.5
y = 22.5
6 = 1/13 (6-7)
Thats mostlikely wrong im sorry \(._.)/
Answer: x = -9
Step-by-step explanation:
-10x - 10y = -10
when y = 10
-10x - 10(10) = -10
-10x - 100 = -10
Add 100 to each side
-10x = 90
Divide each side by -10
x = -9
-10(-9) - 10(10)
90 - 100 = -10
Answer: y= -1/2x + 3.5
Step-by-step explanation:
y=mx+b
Y-3= -1/2(x-1)
y-3= -1/2x+1/2
+3 +3
y= -1/2x + 3.5
