Answer:
y = 17.5
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 35 when x = 140, then
35 = 140k ( divide both sides by 140 )
0.25 = k
y = 0.25x ← equation of proportion
When x = 70, then
y = 0.25 × 70 = 17.5
The answer for this answer would be B. X is less than -10 so B would be the answer.
Since x=8/3 is a vertical line,the slope is undefined,
Answer:
two of the sides are 21 m long and one of the sides is 28 m long
The answer is b so good luck and i hope that helps
