Y varies inversely to x. If y= 7 when x= -4, what is y when x=5?

Step-by-step explanation:

, where k is a constant. (Since y varies inversely to x)

Let's find the value of k first.

when y=7, x= -4,

Thus,

When x=5,

  y = -5.6

Step-by-step explanation:

When x changes by a factor of 5/-4, y changes by a factor that is the inverse of that. (That's what varies inversely means.)

  y = (-4/5)(7) = -28/5

  y = -5.6

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
